Natural gas is inexpensive, seemingly plentiful and much cleaner-burning when used as an alternative to diesel fuel in transportation fleets, so it makes sense that Waste Management is converting its entire North American fleet to run on compressed natural gas. The company announced this week it has added 25 new CNG waste collection trucks to its fleet in Ottawa. About 80 per cent of all new trucks purchased by the company now run on compressed natural gas. To accommodate this fleet conversion, Waste Management has been increasing the number of fuelling stations it has to support the fleet. Currently it operates 17 of these stations across North America, but that number is expected to expand to 50 by the end of this year. Overall, the company has more than 1,400 CNG trucks in its fleet, including 100 added to its fleet in Vancouver last year. While this represents only 3.5 per cent of the entire fleet, conversion is happening at a healthy clip. It should be noted that Waste Management is also using route optimization software to reduce driving time and all trucks are programmed to turn off automatically after five minutes of idling. These are all solid initiatives that will help reduce emissions, but also reduce company costs.

From a greenhouse-gas perspective, the emission reductions aren’t massive — up to 25 per cent reduction — but the real gains here are in the reduction of smog-causing pollutants. Nitrogen oxides and diesel particulate matter are reduced by 90 per cent. Over time, it leaves open the possibility of using renewable natural gas, sourced from landfill gas and municipal wastewater biogas, to displace its fossil fuel cousin. The city of Surrey, B.C., is already heading in this direction. It now requires that natural gas-powered trucks be used for its municipal waste collection, a service being performed by BFI Canada, which has purchased 75 trucks that run on CNG. At the same time, it is launching an organics collection program for Surrey’s 470,000 residents and businesses that will see the household waste converted into biogas that will be cleaned, conditioned and used in BFI trucks. Surrey hopes the new biogas facility will begin operation in 2014.

Toronto was supposed to head in this direction as well, but from what I understand the plan has unraveled under the administration of Mayor Rob Ford.

My Clean Break column this past week looks at the missed opportunity of growing crops for biofuel production when making green chemicals is a higher value proposition, both economically and environmentally.

By Tyler Hamilton

About seven million tonnes of grain corn was grown in Ontario in 2011, and by year’s end roughly 30 per cent of that is expected to go toward ethanol fuel production.

Let’s ignore for the moment the whole food-versus-fuel debate, and assume that devoting nearly a third of Ontario corn production to making renewable fuel doesn’t help drive up global food prices, or for that matter, reduce our capacity to feed the world.

Let’s focus instead on the use of corn as part of a greenhouse-gas reduction strategy that returns more economic value per harvested bushel. Through this lens, is biofuel production the best use of a renewable but also land-limited resource?

Corn, after all, doesn’t have to be made into ethanol and burned in the gas tanks of our cars to reduce our dependence on fossil fuels. It can also be used to make a variety of “green” chemicals that form the basis of a wide variety of products currently made from petroleum-based chemicals.

Let’s take, for example, Burlington, Ont.-based EcoSynthetix, which takes starch from corn to make certain biopolymers. These biodegradable biopolymers can displace petroleum-based ingredients used to make coatings for packaging and cardboard, adhesives, carpet backing, building materials and a wide range of other products.

John van Leeuwen, chairman and chief executive of EcoSynthetix, which had a successful initial public offering on the Toronto Stock Exchange in August, says he can make $35 worth of biolatex for every bushel of corn the company consumes in its process.

Ethanol, by comparison, fetches about $10 for every bushel of corn, he says. Indeed, the amount of corn that’s consumed annually by 10 large ethanol production plants – out of about 200 in North America—could probably supply enough starch for the entire emulsion polymer market worldwide if it were to switch to 100 per cent biopolymers.

More than that, EcoSynthetix’s biopolymer can compete head on with petroleum-based polymers that currently dominate the marketplace, unlike the heavily-subsidized ethanol industry. “We don’t need subsidies. We can actually go into a deal and offer a discount against petroleum-based products to win business,” says van Leeuwen.

Asked about the growing volume of corn consumed by the ethanol industry, van Leeuwen, without pointing fingers, responds sensibly. “We really need to be thoughtful as an industry to make sure what we make derives maximum value from our agricultural feedstocks.”

Such wise advice could be directed to Canada’s bioproducts sector as a whole, which as I wrote in August has been shrinking when it should be flourishing. That was the conclusion of a report by the Richard Ivey School of Business, which called Canada’s performance on the global stage “disappointing.”

In that report, ethanol represented more than two-thirds of Canada’s bio-products market, while higher-value polymers accounted for just 2 per cent and organic chemicals 12 per cent. In the area of green chemicals, Canada’s landscape was described as “stagnant.”

This isn’t just about corn; it’s also about how we choose to use agricultural residues, municipal organic waste, wood waste, algae biomass, and non-food crops.

Does it make sense to just burn this material for energy, or convert it into fuel so it can be burned? Or, should we be doing a better job of targeting niche markets with high-value “green” products that are just as effective at reducing our dependence on fossil fuels?

“There is an overemphasis on biomaterials as a source for energy,” says Dr. Rui Resendes, executive director of Kingston-based GreenCentre Canada, which helps commercialize green chemistry innovations coming out of Canadian universities.

And that energy isn’t as green as often claimed. After all, Resendes points out, the fertilizers used to grow crops are petroleum-based, as are many other products consumed along the supply chain.

“Just because you pluck it out of farmer’s field doesn’t mean it’s sustainable,” he says, adding that the entire value chain has to be considered. This is where green chemistry and the products it supports play a crucial role. “I’m a firm believer in technologies that are addressing niche markets where volumes are much smaller and margins are much higher.”

Green chemicals may be a broad category, but it’s one that serves highly targeted markets where petroleum-based products currently dominate, including the manufacture of fertilizers, polymers, and lubricants, to name a few.

And, as EcoSynthetix is demonstrating, you can be competitive and aim for profitability without relying on subsidies.

This isn’t to suggest we abandon biofuels. Renewable jet fuel, for instance, is emerging as an attractive subcategory of green fuels and fulfills a role that electricity, while an alternative source of energy for consumer vehicles, simply can’t based on current-day technology.

But certainly Canada can have a much more balanced portfolio, and that means doing a better job of nurturing our green chemistry sector, and – in the particular case of corn – getting more pop per kernel.

Tyler Hamilton, author of Mad Like Tesla, writes weekly about green energy and clean technologies.

FYI: This is a presentation and panel that I participated in in late September at the Evergreen Brick Works Forum on Leadership, Innovation and Sustainability. We were confined to a PechaKucha presentation format, meaning you have to go through 20 slides and spend no more than 20 seconds on each one — i.e. total presentation of just six minutes and 40 seconds. Needless to say, we all felt rushed, but it allowed more time for discussion. You can find the other panels here, as well as video of the keynote presentation from Jeremy Rifkin.

It’s shameless self promotion, I know, but this is how you create awareness of books, and the point of writing Mad Like Tesla was to create awareness of the innovation going on around clean energy and the immense barriers inventors and entrepreneurs face. I also wanted to celebrate those much-needed risk takers in society, without whom we will never have the kind of breakthroughs necessary to tackle our energy demons. It’s part of the reason I write and have maintained this Clean Break blog for the past six years, without financial gain. It’s a labour of love, as time consuming as it often can be.

Mad Like Tesla: Underdog Inventors and Their Relentless Pursuit of Clean Energy was launched this month and has been well-received. The reviews so far have been positive, and awareness of the book is slowly building. But not fast enough. I want to take this moment to ask my readers, many of whom have already purchased the book (thank you!), to help spread the word. Share this link or the Mad Like Tesla website (www.madliketesla.com) on social media sites such as Facebook and Twitter. Refer to it when commenting on the various blogs you might follow. And for my media friends out there — whether in the mainstream press or the blogosphere — please consider a review, or alternatively, I’m happy to chat about the many odd and inspiring stories in this book. Please see press release here.

Thank you all for your ongoing interest and support. BTW: Many have asked, so I’m happy to report that the e-book version of Mad Like Tesla is now available at Amazon.com.

My Clean Break column this week reports on a new study out of the Richard Ivey School of Business, which takes a look at the state of the bioproducts industry in Canada. The researchers behind the report analyzed Statistics Canada data between 2003 and 2009 and what they found was a disturbing negative trend — the industry is shrinking, not growing, at a time when bioproducts are desperately needed as part of a strategy to reduce our dependence on fossil fuels; also at a time when the United States and other regions are showing a strong commitment to bioproducts and are enjoying the associated growth.

What’s going on? Well, for one the bulk of bioproducts made in Canada are first-generation biofuels, such as corn ethanol, or other forms of bioenergy. We don’t give enough support to biochemistry research and product development, or higher value non-fuel markets such as alternative plastics, which in my view are much more exportable down the road. We are throwing money at corn ethanol and not doing enough to support and help commercialize next-generation biofuels produced from algae or cellulosic conversion technologies.

I’m pasting my column below, though before you read there are some caveats here. The data analyzed doesn’t cover the past two years, so there may be some positive signs not accounted for in this report. Also, Ontario appears to be doing much better than the rest of Canada, though this is not to suggest there’s enough being done in Ontario. Anyway, I think this report is an important wake-up call for Canada. Sure, we’re blessed with forestry and agricultural resources, but are we satisfied just growing and selling commodities? Are we going to continue down the path of selling our raw natural resources to other countries, only to purchase it all back in the form of higher-value products? Once again, Canada lacks a vision and has no real plan to lead the world on bioproduct development, even though it has the capacity to do so. Click below to read the full column: (more…)
