ABOUT THIS
ISSUE
Last issue, when we announced that this issue
would be about nothing, we probably left some readers somewhat confused. But we
are delivering, with several articles about the environmental importance of
doing nothing, and one about the mathematical significance of
nought.
However, not wanting to be seen as entirely
Scrooge-like, we open this issue with a list of ten suggestions for
environmentally better gifts. GL developed this list and has seen nothing like
it anywhere else. If you are doing some last minute Christmas shopping we
commend it to you as a list of gift ideas that can help reduce the environmental
footprint of the season. Consistent with our theme, we also present a list of
ten popular Christmas gifts that we recommend you avoid because their
environmental cost / recipient benefit ratio is, in our opinion, way too high.
As always, we welcome your comments and will publish a selection of those
received.
A recent International Joint Commission report
is very "unoptimistic" about achieving virtual elimination of persistent toxic
substances in the Great Lakes Basin. We report on this governmental body's views
on the challenges to achieving virtually zero. Farmers have been enthusiastic
about use of what they consider agricultural waste to provide biomass for
energy. A recent study suggests that this may not work - another zero for those
who like to see the world as providing unlimited resources. In Manitoba, a
somewhat related study is looking at how to reduce nutrient loading to Lake
Winnipeg. The partners here include the government, an ngo, and the private
sector.
One green chemistry leader is suggesting that
the greenest solvent may be no solvent. One of his scientific colleagues has
written a song about green chemistry - in the spirit of the season we bring you
some of the words. We are often asked to describe 'green chemistry'. We will
provide more in future issues of GL, but Queen's University has opened a centre
for green chemistry and has provided us with an excuse to provide some of the
explanation. Another approach to green chemistry and green products is the E
factor. The closer the E factor of a product is to zero the better the
environmental performance. Our article in this issue explains.
Our book review in this issue is of (what
else) The Value of Nothing: How to reshape market society and redefine
democracy. Oil sands' tailings ponds in northern Alberta have been attracting a
lot of attention recently and GL brings you its own take on the issue. In a
future issue we will be analyzing the reports of the federal and Alberta panels
that have been set up, but in the meantime we look at Syncrude, Schindler, and
the Alberta Legislature. Virtual elimination does not seem to be high on the
Company's tailings pond agenda. Interface flooring has been a leader in
corporate sustainability for many years. Now the Company's Mission Zero sets a
new pace that may be difficult even for Interface. Zero waste is a fantastic
goal but is it achievable?
CMHC, the federal housing agency, recently
gave out awards for affordable housing. We were pleasantly surprised to see that
the award selection included environmental criteria. We bring you the details.
We also get questions from time to time about the relative merits of paper and
electronic communications. A team of researchers at the University of Bristol
(where one of GL's editor’s nieces is studying) has provided some of the
answers. So far it looks like electronic beats paper in terms of lower
environmental footprint.
Lots of information about climate change has
come out around the annual conference of the United Nations Framework Convention
on Climate Change, this year held in Cancun. Next issue we will bring you some
of that which we see as important including the report from Canada’s
Commissioner of the Environment and Sustainable Development Scott Vaughan.
Meanwhile, enjoy this issue and send us your comments. In this issue, in
continuation of our issue by issue awards for who is good, and not so good, for
the environment, we nominate CMHC for the 'good environment' prize and remote
car starters for the black hat award. Have a good holiday season, whatever your
holiday may be.

EDITORIAL: TEN
LOW ENVIRONMENTAL IMPACT CHRISTMAS GIFTS
As we approach gift season GL's editors
thought we might share some suggestions for low environmental impact Christmas
gifts. Not surprisingly, these are mostly gifts that involve services rather
than durable goods - a switch which we see as key to increasing sustainability.
So, without further ado (another low impact thing, as far as we can tell),and in
no particular order :
- theatre tickets to a local theatre. We have
never seen or done a LifeCycle impact on theatre, but it seems to us that
cultural activities such as theatre likely have lower environmental impact per
dollar spent than almost any material goods. If you cannot find a local
theatre with tickets, or season tickets, for sale, then an alternative may be
an educational course for your friends or relatives.
- museum tickets. With family admissions now
often exceeding $20, and sometimes much more, the gift of admission to a
museum or art gallery makes a very nice holiday gift. Art will appreciate it
too.
- a season of Community Shared Agriculture.
Right across Canada many small farmers are offering CSA programs, where they
grow the food and all the members get a share. Many CSA farmers will sell an
entire season and, if one share is too big, they will sell a half share. This
means that your friend or relatives will get from 12 to 20 weeks of locally
grown, often organic, vegetables that will taste better than anything that can
be bought in the supermarket.
- local food products are always a good choice.
Food is a necessity and, in GL's opinion, food production presents one of the
most sustainable economic development opportunities for Canada. Depending on
where in Canada you live, the following ideas might help you find a
sustainable gift: on the east, west, or south (Great Lakes) coasts, look for
smoked seafood such as smoked mackerel, smoked trout, or smoked salmon. Many
fishmongers can help you choose a delicious local smoked fish product that
does not require refrigeration (as far as GL knows, Santa's sleigh does not
carry any kind of refrigerant).
- garden seeds and planters for growing of food
plants. If your friends or relatives are not yet into gardening for food, then
a book, a few packs of seeds for vegetable production, or a couple of
mini-greenhouses for seed germination can get them started. If they already
grow their own tomatoes, then an electric seed starter mat which warms the
seed tray from the bottom can help. Search for seed starter mat on Google or
Yahoo Search or inquire (by phone, to avoid driving) at local seed supply
companies or nurseries. Growing your own food is a pretty sustainable thing to
do, and getting the seeds started early can help increase production.
- transit tickets or passes. All
environmentally aware folks know that buses, trains, and coaches are far
better than taking you car. Why not encourage you parents, relatives, or
friends to use public transit by giving them a bus or train pass. If they are
not in a situation where they can use transit regularly, gift them a bus tour
or train pass to visit somewhere they would find interesting. Most coach tour
operators as well as Via Rail Canada offer short and longer tours to all kinds
of neat places. Trains and buses are usually lower environmental impact, and a
more pleasant way to travel, than taking your own car.
- a heated mattress pad or electric duvet along
with an automatic turn-down thermostat if they do not already have one. GL is
a big fan of electrically heated bedding. At night one can turn down the home
heating thermostat by as much as 8 or 9 degrees if one has a warm bed. In most
homes it takes far less energy to keep the bed warm, literally only a few
watts per hour, than to keep the whole house warm. Yes, we know a hot water
bottle might be better but we like an electric duvet, available in the US from
bedding retailers but in Canada apparently mostly from EBay - look for Sunbeam
brand - but heated mattress pads are also excellent and cheaper than the
electric duvet. Your gift recipient will only save money and the environment
if they turn down the house temperature overnight so if they do not have one
get them an electronic thermostat as well as the heated bedding.
- a romantic night in a local hotel. 'Nuff
said! But hotels exist and the environmental impact of another occupied room
is pretty small! Many people say they never explore their local tourist sites
unless they have visitors. For over 40 years, the London Free Press (London,
Ontario) has offered a “Shunpiker Tour” which highlights local art, culture,
old-fashioned general stores and other places to see and things to do within a
short distance away. Staying in a local hotel is a great way to explore the
local sights.
- a gift certificate at a store that you know
provides things that the recipient will like. Believe it or not but GL is not
a big fan of gift certificates. But we have to say that giving a gift
certificate so that the recipient can buy something they will use is far
better for the environment than giving them something for which they have no
use. So we endorse the current trend towards gift certificates as long as the
giver puts some thoughts into the store in which the recipient would find
value. If it is an older person or someone who can make good use of the gift
of communication, then consider a long-distance telephone gift card. We
particularly like the series offered by VOX, which is Bell Canada in disguise,
but other brands are probably just as good. The environmental impact of a
telephone call is very low and the social benefit seems to us to be very
high.
- trees for the garden or for a public space
are another environmentally helpful gift idea. Although it is obviously not
possible to plant trees in Canada during the Christmas holiday season, many
nurseries and garden centres offer gift certificates that can be used to plant
a tree when Spring arrives, or you can just pledge to deliver the tree when
the season is appropriate. We don't recommend giving a potted Christmas tree
or garden tree at Christmas time. Even if the tree survives the often dry and
hot conditions inside the home it is unlikely to forgive you for the
transition to the cool damp conditions that will exist outdoors in the
Spring.
Beyond our 10 more sustainable gift
suggestions we also recommend the gift of service. If it is someone who lives
alone, offer to visit their home, bring and make a meal and join with them in
eating together on four, six or twelve occasions during the year or if you are
driving, fill up the car and offer a ride to the grocery store. If it is a
couple or family, offer to bring a meal or help them with the household chores.
If it is a child, offer to play games with them or help them with puzzles or
school work on a specific number of occasions and for a specified length of time
in the coming year. If you have skills that the recipient would find valuable,
offer to teach them, help them exercise, maintain their home, or even babysit
for a number of occasions during the year. Give them a number of coupons for the
activity you have chosen that they can redeem with you so that you and they will
know that the obligation is real and will be delivered. Helping each other has
to be one of the cornerstones of a more sustainable 21st Century
society.
Above all, enjoy the holiday season and help
your friends and family enjoy the holiday season and the year ahead.

THEME: DO
NOTHING TO SAVE TO SAVE THE ENVIRONMENT
The City of Calgary's Rethink Water campaign
called "Do Nothing to Save Water" could be a model for other non-actions which
help to protect the environment. Those who take The Do Nothing to Save Water
Pledge commit to not watering the lawn when
- it's raining, has recently rained or is
forecast to rain.
- it's the hottest time of the day (between 11
am to 3 pm)
- when it's windy.
GL thinks more "do nothing" should apply to
mowing so that lawn areas not actively used e.g. for play or company picnics
could be retired as natural areas for urban and rural biodiversity while saving
fuel. Advice about maintenance of a wooden fence recently suggested that leaving
the natural wood makes the fence last longer and look better than applying a
stain or other finish which wears, needs to be regularly reapplied, and may
release toxic chemicals. In forests, doing nothing about cutting down dead trees
leaves cavities and nest habitat for birds.
Businesses, government and individuals could
"do nothing" in so many ways. Many businesses have adopted various approaches
which encompass the idea e.g. zero waste or lean and green manufacturing, Author
Michael Pollan, who writes about food, suggests that event organizers should not
serve any food or drinks because of the saved environmental effects and because
people tend to eat too much without any further assistance.

THE CONCEPT OF
ZERO: SOMETHING AND NOTHING
The concept of zero is said to have been
invented around 500 AD by Hindu mathematicians who also gave the world the
ten-base (0-9) system. The binary system (0-1) became the foundation for today's
computers where 0 represents the off switch and 1 the on. It took another
300-400 years for the first verified use of the concept of 0 along with the math
to use it e.g. how to add, subtract, and multiply with 0. This advance was
apparently made by Islamic mathematicians although there is a big quarrel on
various web sites about who should get credit - not unexpectedly the writers
call "much ado about nothing." The Romans didn't use zero. It wasn't until the
1200-1300s that zero became known in Europe. Although zero is about nothing, it
is something. It is a number but one with some characteristics not shared by the
other numbers, for example, dividing by zero is a no-no.
Who decides when something is something or
nothing and who pays for the "nothing" which turns out to be something is
crucial to the environment. When Kevin O'Leary, rich guy from the Dragon's Den
show which ironically is run by the publically funded CBC, says "Greed is good
and I love money", he is merely voicing what many accept as the basic tenant of
the free market. We can count money but it is much more difficult to allocate
the non-monetary costs to nature, humans and their societies. Climate change,
health damage, pollution, species loss, soil and natural resources depletion,
exploitation of labour, and the poor, and waste are essentially in many models
counted as nothing. This 'nothing' also has a huge monetary cost currently and
in the future but that cost isn't allocated to the O'Learys or the companies
they run.

LITTLE ZEROS:
GREAT LAKES TOXICS 1995
What seems like a long time ago, at a time
perhaps of more optimism about action on the environment, the Little Zeros
campaign was launched to achieve zero discharge of persistent toxics into the
Great Lakes basin. Great Lakes United provided the communications network Little
Zeros Watch for the citizen groups who were asked to focus "on eliminating
sources of persistent organic pollutants in their local communities - one zero
at a time". An article in the International Joint Commission newsletter of the
time by GLU's Scott Sederstrom described eliminating persistent toxic releases
to the Great Lakes from hospitals and health care institutions as one of the
eight Little Zeros campaigns. Releases from the health care industry include
incineration of medical waste with emissions of dioxins, partly from polyvinyl
chloride in medical waste. Hospitals are also sources of mercury due to
batteries, fluorescent and high intensity mercury vapour lamps, thermometers,
specialty papers and films and pharmaceuticals.
What has happened to the Little Zeros campaign
today we know not, but we do know that many healthcare institutions in the Great
Lakes basin are taking the environment much more seriously, though, as always,
we are sure the industry would agree that more remains to be done.

GREAT LAKES:
VIRTUAL ELIMINATION OF TOXICS
The International Joint Commission was formed
to assist the two countries in their cooperation to manage the Great Lakes and
other waters wisely and to protect them for today's citizens and future
generations. The 1978 Great Lakes Water Quality Agreement replace the 1972 with
an ecosystem approach with a broad range of pollution reduction programs. The
Agreement called for the virtual elimination of the input of persistent toxic
substances following a zero discharge philosophy.
A 2010 IJC report on groundwater is very
unoptimistic about the chances of making progress on the virtual elimination
strategy. Just the groundwater contaminated by the 4,500 known hazardous waste
sites around the Great Lakes basin would carry an average price of $27 million
per site on average for a total of $US112.5 billion needing multiple decades of
effort. Recommendations include:
- proper monitoring systems e.g. Ontario
doesn't know how much hazardous waste is moving around.
- minimizing the amount of hazardous waste
produced would reduce the effects of hazardous waste.
- the four R's can be implemented by industry,
government and individual. Reduce, recover, reuse and recycle.
- Education is needed to reduce hazardous
waste. Canadians improperly dispose of 27,000 tonnes of household hazardous
waste
- Industries can reduce hazardous waste by more
efficient manufacturing processes, using alternative compounds and using or
reprocessing waste.
State of the
Great Lakes
It is not only past pollution which is
affecting the Great Lakes but virtual elimination is not a reality for current
emissions. The State of the Great Lakes report published in 2009 based on the
State of the Lakes Ecosystme Conference SOLEC held in Niagara Falls, Ontario in
October 2008 discussed the indicators of the Great Lakes. In terms of
contamination, the releases of specified bioaccumulative chemicals have declined
significantly over the past decades but in some areas the decline is slowing and
new contaminants are increasing. For the most part, contamination doesn't limit
reproduction of fish, birds and mammals. However, while the concentrations of
contaminants in open water is low, some local ares including bays and Areas of
Concern have higher concentrations The report states "The lakes continue to be a
receptor of contaminants from many different sources such as municipal and
industrial wastewater, air pollution, contaminated sediments, runoff, and
groundwater."

BIOMASS YIELDS
FOR CORN-SOYBEAN ROTATIONS: POSSIBLY CLOSE TO ZERO
Maintaining soil carbon is essential for
ensuring soil structure, binding nutritients, providing energy for growth of
plants and organisms in the soil and to prevent wind and water erosion.
Elizabeth Schouten, a third year agricultureal economics student at the
University of Guelph, writes about the research on how much biomass can be
removed from farm land. She wrote in the Fall issue of the magazine of the
research partnership between Ontario's Ministry of Agriculture and the
University. Professors Bill Deen, Reen Van Acker and Alfons Weersink are
researching how much crop residue needs to be returned to the soil and how much
can be removed for use as biomass to produce electricity and heat generation. So
far, the estimate is that 2.5 to 4 tonnes of residue needs to be returned. Crop
rotations which use cover crops or more complex rotations which include corn,
soybean, wheat and red clover could build up biomass levels. A typical
corn-soybean rotation doesn't produce enough to allow removal of any significant
amount of biomass each year although removal less often might be an option in
some areas. Another article in the magazine explores other sources of biomass
including annuals such as sorghum and millet as well as perennials such as
switchgrass, miscanthus, big blue stem and reed canary grass. These have pros
and cons in terms of cost to plant, yields, perennials which take time to grow
but can be harvested more than once while annuals provide income in the same
year.

MADE-ON-MANITOBA LAKE WINNIPEG POLLUTION
PREVENTION
In November, Manitoba Premier Greg Selinger
announced funding of $150,000 to support a pilot project to prevent pollutants
entering Lake Winnipeg in partnership with the International Institute for
Sustainable Development and the University of Manitoba. Lake Winnipeg is the
tenth largest freshwater lake in the world and nutrient loading is exceeding its
ecological capacity.
Grass from 200 hectares of the marsh will be
cut and the biomass burned to replace coal. reducing greenhouse gas
emissions.The grass stores pollutants which would have eventually polluted the
marsh or Lake Winnipeg. It should also be possible to recover phosphorus and
nitrogen which pollute the lake but which are otherwise valuable
fertilizers.
The announcement was made as part of the
Premier's keynote speech at the IISD's Lake Winnipeg Basin Summit. which
focussed on "creating and taking advantage of opportunities for Manitoba’s
economy, while reducing the nutrient loading within the Lake Winnipeg Basin."
One of the co-facilitators was John Fjeldsted, executive director of the
Manitoba Environmental Industries Association, who sees it as important to
include Manitoba businesses in such bioeconomy solutions.
Like the bans on the cosmetic use of
pesticides first introduced by a few cities in Canada, Manitoba's ban on
phosphorous in dishwashing detergent led to further intiatives elsewhere. The
federal government followed Manitoba's lead to ban high levels of phosphorous
levels in household dishwash detergents effective July 1, 2010.

GREEN
CHEMISTRY: THE BEST SOLVENT IS NO SOLVENT
For many industrial and laboratory
applications including pharmaceuticals, chemicals are used for many purposes not
necessarily ending up as an element in the final product. These processes use
solutions including solvents which often contain toxics e.g. volatile organic
compounds. Green chemistry approaches seek to replace these solvents e.g. with
water or develop alternate reaction processes not requiring the catalysts. If
catalysts are required, green chemistry practitioners are seeking to recover or
recycle the catalysts which otherwise end up as toxic waste. In October 2010,
the Green Solvents for Synthesis conference was held in Bavaria. Germany. The
opening lecture was by Philip Jessop of Queen's University (Kingston, Ontario)
talking about green solvents. He spoke of three types of green solvents:
Replacement green solvents, Really green solvents, and Revolutionary green
solvents, but suggested that there aren't enough replacement green solvents to
meet the needs. Although some green solvents have been assessed most green
solvents haven't been. Philip Jessop is the Canada Research Chair of Green
Chemistry.
During the evening, Walter Leitner from
Germany led a song called Always Use Green Chemistry Tools (1) which has several
stanzas including:
...
If the process seems absurd
And “waste” is the final word
Green Chemistry will show a better
way!
Just save energy and steps
Of course, catalysis can help
And your profits will shoot up to the
sky!
Chorus:
And Always use the Green Chemistry

Dr. Jessop has been awarded the 2010 Queen's
Prizes for Excellence in Research. This is the highest honour given by Queen's
University to recognize the research excellence of its faculty. His group of
research associates and graduates students named the Jessop Group are
researching how to minimize waste e.g. Switchable Chemistry seeks to separate
and recover oil from waste plastic bottles and recycle polystyrene foam plastic.
Jessop is also the Technical Director of GreenCentre Canada (see separate

In August 2010, the facility for GreenCentre
Canada was officially opened. in Kingston, Ontario. The Executive Director is
Dr. Rui Resendes, a chemist who has worked in business include Bayer

Director. Funding is from governments of Ontario and Canada as well as industry
sponsors. Currently the eight industrial sponsors are:
- Fielding Chemical Technologies Inc.
- Ford Motor Company
- NexCycle Plastics Inc.,
- NOVA Chemical Corp.
- Polycorp Ltd.
- Pressure Chemical Co.
- Stepan Company
- Veolia Water Solutions and Technologies
(VWS).
The facility focuses on Green Chemistry which
is making chemical products and processes that eliminate or reduce damage to the
environment while reducing waste and energy. The team is assessing discoveries
from universities and industry with some technologies ready to license to
industry.
Twelve
Principles of Green Chemistry
Among the twelve principles of Green Chemistry
are:
1. It is better to prevent waste than to treat
or clean up waste after it is formed.
...
5. The use of auxiliary substances (e.g.
solvents, separation agents, etc) should be made unnecessary whenever possible
and innocuous when used.
6. Energy requirements should be recognized
for their environmental and economic impact and should be
minimized.
7. A raw material feedstock should be
renewable rather than depleting wherever technically and economically
practical.

E(NVIRONMENT)
FACTOR BEST IF ZERO
Roger Sheldon was Professor of Biocatalysis
and Organic Chemistry at the Delft University of Technology (The Netherlands).
when he retired in 2007. He had developed the measure called E factor as one way
to account for environmental acceptability of chemical processes. The E factor
is the mass ratio of waste to desired product ie E = kg. waste/kg. of product.
Counted in this measure are reagents, solvent losses, all process aids and
although it is often difficult to account for, in principle, fuel. Not counted
is water. Some production methods have soaring E factors, for example
pharmaceuticals often have an E factor of greater than 100 while bulk chemicals
have less than 5. The higher the E factor the greater the waste and in theory,
the greater the potential for negative environmental impact.
The Royal Society of Chemistry awarded Roger
Sheldon the 2010 Green Chemistry Award. as "one of the founding fathers of green
chemistry and in particular for his work on the development of clean, catalytic
technologies for waste minimization and elimination of toxic/hazardous materials
in chemicals manufacture."

THE VALUE OF
NOTHING
In the Value of Nothing, author Raj Patel
philosophizes about "how we inflate the cost of things we can (and often should)
live without, while assigning absolutely no value to the resources we all need
to survive." [from back cover] He accuses corporate interests of privatizing
profits and socializing risks (ie transferring social and environmental costs to
the public.
One of the topics he discusses is opportunity
cost. Opportunity cost is an important concept in economics. The Economist
explains it as "the true cost of something you give up to get it."
Patel says that the concept has implications
for the environment and society citing Larry Summers. now director of
President's Obama 's National Economic Council, once Patel says wrote while at
the World Bank that, "Just between you and me, shouldn't the World Bank be
encouraging more migration of dirty industries to the LDC [Less Developed
Countries}." The idea is that poor people value environmental harm less than
rich people.
Dumping waste is Africa is common. In Somalia,
hazardous waste is disposed of at a cost of $2.50 a barrel while in Europe,
disposing of that same barrel would cost $1,000. In 2005, the tsunami brought
barrels of toxic waste from offshore Somalia to the coast causing chronic
illness and radiation sickness.
Patel charges that the common economic
language ignores the fact that different people have different opportunity
costs. There is no single opportunity cost for all. Patel says, "Economics is
about choices. But it's never said who gets to make them. By choosing to value
the world through markets, we choose the principle of "The more money you have,
the more you can get." The opportunity cost of the company ridding itself of
toxic waste is different from that of a Somalia woman whose entire family is
affected by toxic disposal. She values her children just as highly as any rich
person in America or Germany but because she is poor, she is not taken into
account in the calculations of cost and benefits.
Patel provides some example of more
involvement of people in defining which opportunity costs provide the most
important benefits for their costs. For example, Port Alegre Brazil has citizen forums to decide
priorities for community funds and which groups get government money. The
opportunity cost of the city is debated. Since the 1990s, close to 100% of the
population has been connected to water and over 80% to sewage. Three times as
many children attend school The process is more transparent, more efficient, has
redistributive power and direct democracy. Rules and limits help to protect
future generations from today's decisions. This approach isn't perfect because
of the potential for democratic tyranny but just as any other system, work can
be done to improve but it reflects the potential for better definition of
opportunity cost, says the author.

SYNCRUDE: OIL
SANDS TAILINGS - SOMETHING MORE THAN NOTHING
Sun Oil Company later to become Suncor was the
first oil sands operation in northeastern Alberta in 1967. Syncrude opened in
1978 and by April 1998 had produced the billionth barrel, five years ahead of
time. Writing in a corporate report in 1993, Eric P. Newel, then President and
CEO compared the scale of the innovation to extract oil from sand to powered
flight, the polio vaccine and television: "Things that challenge our assumptions
about what is and what is not possible." He also said, "It is also a story of
technology, triumph over the elements - and teamwork." The brochure goes on to
say that Syncrude "learned how to protect, preserve and restore the environment
we would come in contact with during the construction and operational phases of
the project. Back then it was an innovative way to look at things. Preventing
environmental problems - rather than trying to cure them after the fact", so the
report continues.
Perhaps what is not said about what is in the
tailings pond is also important:
"fine tailings - a 'muddy water' residue from
the bitumen extraction process consisting of about 85 percent water and 15
percent fine clay particles." and in its 1995 report "Fine tailings - a
colloidal (gel-like) material resulting from the processing of clay fines
contained within the oil sand processed by Syncrude, consisting essentially of
clay fines and water." In its 1995 the annual report says the company is engaged
in local community partnerships "that are seeing wood bison returning to their
traditional range, ducks and wildlife enjoying healthy, new habitats and local
residents confident in their health and safety." Every year the reports state
that Syncrude is finding solutions to reducing the tailings ponds.
Syncrude:
2008/2009 Annual Report
In the 2008/2009 report the definition of
tailings has changed to: "Tailings are composed of a mixture of water, sand,
clay, fine solids, residual hydrocarbon and salts—all of which are naturally
found in oil sands deposits. Tailings are stored in mined-out areas and large
above-ground containment structures commonly referred to as settling basins or
tailings ponds."
Elimination is not top of the agenda. As the
report says, "The public understands that tailing ponds are a necessary
component in the processing of the oil sands." The report does suggest new
technologies for managing mature fine tailings including one of the conditions
of its approval, centrifuging by 2012. Remediation using microbes and less
bitumen in the tailings ponds through a secondary recovery system are options
considered. The reclamation of the West Mine is said to be the first
commercial-scale demonstration of water capping, which is water put on top of
the tailings residue to form a "fresh" water lake.
Today four companies operate in the Athabasca
Oil Sands Region in Alberta: Suncor Energy Inc., Syncrude Canada Ltd., Shell
Canada Ltd. (Shell), and Canadian Natural Resources Limited.

WHAT IS REALLY
IN THOSE TAILING PONDS?
Leakage of tailings fluid into groundwater,
migratory birds landing and dying on oil slicks in the ponds, large areas in a
boreal area turned from habitat into wasteland and air pollution are just some
of criticisms which lead activists to call for an end to "dirty
oil."
Even opportunities show that the tailing ponds
are more than just fine. One study in 2005 by University of Alberta researchers
indicated "the heavy minerals contained in the froth treatment tailings produced
by Syncrude Canada Ltd and Suncor Energy Inc represent about 6% of the world’s
production of TiO2 and about 9% of the world’s production of ZrO2." Samples
indicates that the amount of bitumen residual in the tailings ranged from 4% to
23%. Recovering these would add value and reduce pollution.
A review of reclamation options for oil sands
tailings by BGC Engineering Inc. for the Oil Sands Research and Information
Network at the University of Alberta says tt can take centuries for the
very fine material in tailings to settle. Most reclamation is done by increasing
the solid content of the tailings e.g. adding sand, leftover soil from the open
pit mining. Reclamation options may depend on technology used. Issues
include
- concentrations of sodium, chloride, sulfate
and boron in sufficient concentrations to be toxic to plants. Some species can
adapt more than others. There may even be a role for some salty wetlands but
the number which should be made are much less than the tailings available. And
these saline area might never progress to other species.
- high rates of fertilizer might be needed to
overcome the lack of nutrition and non-existing soil microbial activity in the
tailings "soil." Such fertilizer adds to the salt. Also it is unknown whether
the plants can survive after the fertilizer is no longer
applied.
In December 2009, David Schindler and other
researchers wrote in a science paper that the oil sands including tailings ponds
are responsible for increases in air pollution through polycyclic aromatic
compounds (PAC). This air pollution settles on snow and when the snow melt is
washed into the Athabasca River and its tributaries damaging fish. Schindler
says Canada's Fisheries Act has zero tolerance for release of contaminants which
kill fish and the Act should be enforced. (1)
Schindler also has criticizes the role of the
industry-funded Regional Aquatic Monitoring Program (RAMP) responsible for monitoring pollution. RAMP
has concluded that oil sands have minimal effects on health and the environment
due to pollution of nearby aquatic ecosytems. Schindler says RAMP lacks
scientific oversight, doesn't make data publically available and doesn't make
its methods transparent. Schindler wrote in a recent issue of Nature about the
“scarcity of peer-review science” in regard to the protection of the Mackenzie
River watershed of which the Athabasca River is a part saying that “the fox has
been left in charge of the henhouse.”
The Fall 2010 report of Canada's Commissioner
of the Environment and Sustainable Development says that Environment Canada has
only one long-term water quality monitoring station in the area and that is in
Wood Buffalo National Park. It was set up to monitor for pulp and paper effects
not oil sands. There are no baseline measures or long term data tracking to
evaluate what the oil sands are doing to water quality and to aquatic ecosystem
health. The first commercial oil sands operation began in 1967. Neither
provincial nor industry data is available to add to Environment Canada's
database of long term data.

OILS SANDS
TAILINGS ELIMINATION: THE ROAD NOT TAKEN YET
On Earth Day April 22, 2010, Alberta Premier
Stelmach asked that oilsand companies take steps to reduce the size of the
tailings ponds or if need be, the province would get tough. He suggested the
goal was to eliminate wet tailings ponds "within a few years" but would give no
defined target.
DIRECTIVE
74
The following day, the Energy Resources
Conservation Board issued approvals for more tailings ponds including Syncrude
and more approvals followed after that for the rest of the year. Conditions are
said to be stricter than previously due to Directive 74.
When the ERCB set out Directive 74 in 2009 it
set out new requirements for the regulation of tailings operations for the oils
sands and said this "is the first component of a larger initiative to regulate
tailings management." ERCB definition of tailings: "A by-product of the bitumen
extraction process composed of water, sand, fines, and residual bitumen."
Companies can use a suite of technologies to meet the directive. Companies in
previous applications committed to converting fluid tailings to deposits ready
for reclamation but have failed to meet targets set out in their applications so
tailings ponds have grown in number and size. Decisions by the Alberta Energy
and Utilities Board and joint panels of the EUB and the Canadian Environmental
Assessment Agency have long term objectives including:
- "to minimize and eventually eliminate
long-term storage of fluid tailings in reclamation landscape.
- to create a trafficable landscape at the
earliest opportunity to facilitate progressive reclamation
- to eliminate or reduce containment of fluid
tailings in an external tailings disposal area during operations
- to reduce stored process-affected waste water
volumes on site;
- to maximize intermediate process water
recycling to increase energy efficiency and reduce fresh water import;
- to minimize resource sterilization associated
with tailings ponds; and
- to ensure that the liability for tailings is
managed through reclamation of tailings ponds."
Two joint panel decision reports issued in
early July 2004 directed EUB staff to address tailings management issues through the establishment of
industry-wide performance criteria

ALBERTA
HANSARD: TAILINGS ELIMINATION
In the Alberta Hansard on October 27, 2010,
Rachel Notley, NDP Environment Critic, asked the Environment Minister,
"Yesterday we learned about another serious environmental tragedy in the Wood
Buffalo region. The impact on migratory birds is only one of the many threats
that toxic tailings lakes pose, yet this government has already allowed them to
cover a hundred and seventy square kilometres, and they’re growing as I speak.
To the Minister of Environment: why won’t this government take real action to
force companies to stop the growth of tailings lakes and eliminate them as soon
as possible?"
Environment Minister Rob Renner replied, "I
would suggest that the hon. member should have a look at the facts. The facts
are that we are taking real action, and the evidence is in the retirement of
Suncor’s tailings pond. Directive 074 clearly enunciates the
responsibility of industry to implement technology that is going to severely
restrict the growth of tailings ponds in the medium term and reduce the overall
tailings pond legacy in the longer term."
Notley responded, "Given that, at best, the
ERCB directive 074 will see toxic lakes grow well beyond 1 trillion litres of
toxic waste and that they will be with us for at least another 50 years – that’s
in the directive – and given that the ERCB has waived its weak-kneed measures 7
out of 9 times in the last year and a half, why won’t the Minister of
Environment admit the truth, that his current half-hearted measures will never
get rid of these toxic lakes?"
Renner replied, "I won’t admit it because it’s
not true. The fact of the matter is that the ERCB has not, as this member
characterizes, waived the directive. What they have done is allowed for
additional time to implement. Let’s be absolutely clear to all members of this
House and to all Albertans that it is a complete commitment on the part of the
government and on the part of the ERCB to implement directive 074. It will
happen."
From GL's reading of it, the directive does
phase in more requirements to convert wet fines to dry and push towards earlier
reclamation but by requiring a percentage of fines to be dried compared to the
total does not lead to the elimination of tailings ponds. It may not even lead
to a reduction if the oil sands productions expands. The minister did
acknowledge that Directive 74 wasn't the "be all and the end all" of government
action but didn't mention what further action might be. Alberta suffering from
the recession is very interested in increasing the competitiveness of the oil
sands.

IDEAS ON WHAT
NOT TO BUY AS A CHRISTMAS PRESENT
This issue we shared some ideas on holiday
gifts with a lower environmental footprint. But overall the end of year holidays
are pretty bad for the environment with far too many unneeded gifts being
exchanged. Gold, frankincense and myrrh were not really setting a good model
though at least the two last are renewable and may have medicinal benefits. GL
does not want to be labelled as a Scrooge, which is why we presented a list of
environmentally reasonable gift ideas before this, our list of ten items that we
recommend not be bought as holiday gifts.
1. Perfume and scents
The huge floor area dedicated to perfumes and
scented cosmetics in department and drug stores is indicative of an absurd
obsession with making ourselves smell nice. But that odour of perfume means that
volatile organic compounds, a precursor of smog, are being released into the
air. Quite a lot of people react quite badly to perfumes so many offices,
educational institutions and hospitals have moved to ban perfumed people from
the premises. GL sees perfumes and scented cosmetics as inappropriate and
unnecessary pollutants and urges our readers not to buy them as
gifts.
2. Remote car starters
Come on, fellow Canadians, you are not that
wimpy! Cars are bad enough but remote car starters are the epitomy of the driver
who has no concern for the environment, even though most users of remote car
starters probably do not realize the damage they are doing. Idling cold engines
produce more air pollution than any other phase of the driving cycle. Starting
you car to warm the interior is as inefficient use of petroleum fuels as you can
get. GL strongly recommends against remote car starters for Christmas or at any
other time.
3. Tins of biscuits, cookies, candies, or
cakes
We have no idea where the idea that cookies,
candies or cakes contained in a tin are more luxurious than those wrapped in a
coated paper or boxboard package came from, but it is not good for the
environment. There would not be so much so bad about the tin if it were recycled
at the end of its life, though even then it would have a greater environmental
impact than the cardboard box, but the fact is that few recycling programs will
accept empty cookie or candy tins. We suggest handmade cookies or candies in a
bag or a commercially packaged box or bag of cookies or candies in place of the
traditional tin.
4. Ceramics, unless known to be wanted and
useful
Ceramics, such a clay mugs, ornaments, or even
ceramic cooking pots, are manufactured by heating clays to very high
temperatures in kilns that are heated with fossil fuels or electricity. As a
result they have a huge amount of what is called 'embedded energy', the energy
required to manufacture a product. The kicker comes because they are not
recyclable and are likely never to be recyclable. If the product is a cooking
pot that is wanted by the recipient and which will be used then it may be
environmentally reasonable because the ceramic is very durable and will have a
long life, but if the recipient has no use for it and does not know someone who
would use it to whom it could be regifted then a ceramic gift is unlikely to be
an environmentally responsible gift.
5. Home biodiesel kits
There are quite a few home biodiesel kits on
the market and one of them may seem a good idea for the farmer or smallholder
who can produce their own vegetable oils or for the frequent fryer who has much
used vegetable oil to spare. However, we have yet to see a home kit than can
produce biodiesel that meets the ASTM D6751 standard. This standard means that
use of the biodiesel will not harm the engine or produce excessive emissions. A
biodiesel product that does not meet this standard is likely to produce
excessive air pollutants when burned in the engine and it may cause problems for
the engine. Some of the kits also use highly flammable and volatile solvents
and/or a great deal of liquid waste materials. GL's view is that production of
biodiesel is something best left to the professionals.
6. CDs or DVDs
Assuming the person to whom you are thinking
of giving a gift of audio, video, or software entertainment already has
equipment capable of receiving a download, GL recommends gifting such things in
purely electronic form rather than as a CD or DVD disc. CDs can be recycled but
we have yet to see any recycling collection programs for used CDs in Canada,
though you can mail them to one of a small number of recycling facilities in the
US. But, even with recycling, the energy associated with an electronic download
is far less than the energy associated with a material disc so we recommend the
electronic version as preferable to the plastic version. If you must give a hard
copy, download the file and put it on a memory stick. At least the memory stick
may be more reusable than the CD.
7. Liquid fuel powered toys such as ATVs and
personal watercraft
GL is increasingly becoming concerned about
the burning of fossil fuels, especially gasoline and diesel, for entertainment
activities. Whether it is automobile racing, all terrain vehicles, monkey bikes,
snowmobiles, or personal watercraft, GL recognizes that powered vehicles may
have legitimate uses in accessing remote areas but when these things are used
only for entertainment then they are creating air pollution and contributing to
climate change in a way that can only be described as a waste of resources. They
are also often used in ways which have significant adverse impacts on wildlife,
threatened species of plants and animals, and water quality. GL recommends human
powered mobile entertainment equipment, such as bicycles, scooters, skates, and
skis, as much more environmentally responsible mobility devices.
8. Candles
Candles seem to have great appeal and some are
even sold as environment friendly air purifiers or sources of light. GL has seen
much evidence of indoor air pollution and fire risk from wax candles and oil
lights and no evidence at all that they can purify air. The yellow part of a
candle flame is glowing particles of carbon and other materials. As those
particles rise out of the flame they cool and can contribute quite significantly
to indoor air pollution and the resulting health risks to those with respiratory
problems. Some are claiming that beeswax or soy candles produce less air
pollution. So they may but why add any air pollution to your indoor space.
Electric light adds no indoor air pollution and adds far less pollution per
lumen of light than any candle: GL recommends electric light (and flashlights
but only if powered by rechargeable batteries) as environmentally preferable to
candles or oil lights under any circumstances. [If you wish to give a gift of
light, consider a donation to Light Up the World: see www.lutw.org. GL's editor
is a director of this charitable international development
organization.]
9. Another stuffed toy.
GL is not so Scroogy as to be against stuffed
toys but North American sales of stuffed toys have skyrocketed to no good
environmental purpose at all. It seems that most children have a favourite
stuffed toy, or maybe two or three, but when a child has more than five or six
stuffed toys then, in our opinion, it is wasteful to give more. Stuffed toys for
teens and adults also seem to have little environmental merit. One of the gifts
from our environmentally preferred products list would seem to make much more
sense.
10. Anything unwanted
Regifting may be the term of the decade but it
is really indicative of a product that does not have a proper home. Manufacture
of that product had an adverse impact on the environment and in some cases use
of the product will have a further adverse environmental impact. Passing it from
person to person until it finds a home with someone who wants it may be better
than the first recipient throwing it away but it is still an inefficient process
and the final recipient may still not be an enthusiast for the product. Far
better to find out what it is that the people to whom you give gifts can really
use and to give them something from that list. If that is not possible, refer to
the this issue of Gallon Environment Letter for our list of suggested low
environmental impact gifts.
10a. Too Many
Reusables are great but distributing them in
quantities that are too large means they quit being reused. As a speaker, GL’s
editor often gets speakers gifts including windup flashlights, windup radios,
mugs, water bottles without BPA and other stuff that has environmental features
and usually presented in reusable bags. On one level, it is great that people
are thinking about the environment. On the other hand, it feels a lot like the
Sorcerer’s Apprentice who conjured up one broom to carry his water bucket for
him and ended up with far too many brooms.

2010 CMHC
AFFORDABLE HOUSING AWARDS
Canada Mortgage and Housing Corporation (CMHC)
announced nine winners of its 2010 affordable housing awards in Ottawa on
November 16, 2010. This will be the last such awards. CMHC is Canada's national
housing agency. The winning projects were:
Doug Story Apartments - Vancouver,
BC
Glacier Duplexes at Rainbow - Whistler,
BC
Harmony Housing Project - Abbotsford,
BC
Harold Green Building - Toronto,
ON
Independence Place - Summerside,
PE
Independent Supported Housing Initiative -
Halifax, NS
McKenzie Heights - Pembroke, ON
Résidence Parc Jarry - Montréal,
QC
Stadacona Plaza - Winnipeg, MB
Each project has a description which includes
societal, environmental and economic features. Examples include
- converting and upgrading old buildings. In
one case, large one bedroom units were converted into two bedroom units to
provide what single parent families needed. The total amount of space within
each unit was the same.
- energy and water efficiency built in to
reduce ongoing costs: energy-efficient lighting, ENERGY STAR qualified
appliances, extra insulation, low-flush toilets and low-flow shower heads
low-e windows, insulation. Energy upgrades affect affordability with lower
utility costs.
- passive solar design e.g. orientation towards
the southwest to maximize sun exposure.
- location with easy access to transit, grocery
stores, hospitals, local parks, trails and other community. Buildings close to
the community mean residents most of whom don't have vehicles can still belong
to the community.
- Mortgages and rents which are affordable e.g.
for one project, a covenant keeps rents affordable for 10 years after
opening.
- selection of materials was for low
maintenance.
- Common areas equipped with occupancy
sensors.
- units designed to be accessible to
wheelchairs with appliances reachable by a person in a wheelchair.
- conversion of abandoned buildings which are
located in community areas. For example, the Pembroke Ontario project was an
old school converted with minimum structural changes.

ENERGY USE OF
EMAIL AND WEB BROWSING: NOT QUITE NOTHING
Electronic communications might seem to be
something that uses no energy and hence has no environmental impact but of
course such is not true. A recent paper from researchers at the University of
Bristol in the UK has attempted to quantify the energy burden that
computer-based communications will impose on the planet. The good news is that
the planet's energy systems apparently can carry the load, though some serious
efforts to reduce 'digital waste' - information downloaded but not actually used
- will be necessary..
The researchers have found that current energy
demand for bandwidth is four watt-hours (Wh) per MB. To put that in context, a
typical Canadian house without electric heating uses 30,000 watt-hours of
electricity per day. The researchers estimate that typical global per person
demand for bandwidth by 2030 will be 3200 MB a day. The power required to
support this activity is estimated to be 1,175 gigawatts. Again for context,
current worldwide installed generating capacity is about 4,000 gigawatts,
according to the US Energy Information Administration. The authors of the study
state that a factor 60-performance improvement (60 times performance
improvement) is needed if infrastructure energy is to be provided by one per
cent of renewable energy capacity in 2030, but historical trends suggest that
this will be reached around 2021.
GL thought it would be interesting to compare
the energy used to manufacture a sheet of office paper with the energy required
to browse the web. According to US EPA data, a ton of office paper requires
roughly 40 million Btus (British Thermal Units - a very non-decimal unit of
energy) to manufacture and deliver to retailers. A ton of office paper is
roughly 200,000 sheets so one sheet of paper contains 'embedded energy' of 200
Btus. Four watt-hours of electricity is 13.66 Btus so if you are getting more
than the equivalent of 14.6 sheets of paper of information you need and use each
hour from your internet bandwidth then internet is an environmentally better
choice for communication than paper from an energy perspective.
As noted by the authors of the University of
Bristol paper, which was delivered from the UK to a conference in the US by
remote connection, none of these calculations includes the energy required to
manufacture the devices, either the desktop computers or the equipment that
makes up the network. More work is needed to look at these aspects.
[Note: this article was prepared from an
abstract of the Bristol University research as the full paper was not available
at the time this issue of GL went to electronic press. We will update if
necessary when we get the full paper.]
