A composting plant’s odoriferous problem

Orgaworld sees big money in compost. But first, there’s the matter of that stench.

The shuttering has thrown into turmoil Ontario’s delicately balanced composting system. Toronto once sent a quarter of its green bin refuse to London; it may now have to resort to shipping that trash to a landfill. Nor is Orgaworld alone. Universal Resource Recovery, which has processed up to 25,000 tons of York Region’s organic waste in Welland, Ont., has been forced this year to throw millions of dollars into revamping its facility because of ongoing smell complaints. And when the city of Toronto last year scrapped its contract with Halton Recycling Ltd. after a Toronto Star investigation found the company was shipping organic waste to a Michigan landfill rather than actually composting it, the plant’s neighbours in Newmarket, Ont., breathed a cleaner-tasting sigh of relief: it meant the facility would no longer take on Toronto’s diapers, pet waste and plastic bags.

The ministry’s Blanchard notes that many composting plants manage to operate with no odour complaints. But industry observers say those few odoriferous operations have hoisted a smelly pong on the business. “We really need to get our collective stuff together as an industry and sort this odour issue out,” says Paul van der Werf, president of 2cg Inc., an environmental consultancy with a waste diversion focus.

All this serves to highlight how frail the organic composting industry remains in many parts of Canada—even in Ontario, where Premier Dalton McGuinty promised to divert 60 per cent of the waste from landfills by 2008. Observers say Ontario’s industry remains underdeveloped because McGuinty’s commitment has never been followed up by policy designed to drive large-scale organic composting. Although residential organic waste programs are now the norm in large cities, no mandate has been directed at industrial, commercial and institutional operations—big producers like hospitals and restaurants.

Hence all the small potatoes. Van der Werf estimates the market value of processing residential organic waste into compost, then selling the resulting fertilizer to farmers, at just $75 million a year in Ontario (throwing in industrial, commercial and institutional organic waste might put that figure just south of $100 million). “It’s not an industry—it’s definitely not an industry because it’s not viable yet,” says the Compost Council of Canada’s Susan Antler, who notes another policy driver: tipping fees, the per-ton cost of burying garbage at the landfill. Composting doesn’t become a profitable alternative to burying trash until those fees hit around $60; in Michigan, still the destination for a lot of Ontario trash, they hover at $30.

Europe’s dense populations and tight quarters have encouraged a thriving organics industry there. So, too, has the European Union’s directive asking members to reduce the amount of organic waste they landfill to 35 per cent of 1995 levels by 2016. It’s no surprise, then, that many organic waste operators in Canada are European (both Hamilton and the Region of Peel have partnered with the Christiaens Group, another Dutch firm, for their composting technology, while Moncton, Edmonton and All Treat Farms in Arthur, Ont., use the GORE Cover system developed in Germany).

Orgaworld’s two Canadian operations—the embattled London plant and a second facility that opened this year in Ottawa—sought to reproduce the company’s success in the Netherlands, Belgium and the U.K., where its parent company, Shanks, moved out of the landfill business and into composting a few years ago in response to high tipping fees. The shift has made Britain’s only listed waste management group an attractive morsel. Last year Shanks fought off a buyout attempt by Carlyle, the private equity investor.

Over half of Shanks’s business, according to its 2010 annual report, is in the Netherlands, with revenues of $570 million there this year. It did just one per cent in Canada, a market, the report states, “which has significant potential in terms of volumes and to date has few competitors.” Despite its trouble in London, Shanks is therefore being aggressive about getting a foothold in the Canadian market. Orgaworld is spoiling for a fight over its newer Ottawa plant, which under a provincial certificate of approval is allowed to handle only kitchen scraps and yard waste but which the company wants to see handle used diapers, pet waste and plastic bags, too (the Ottawa plant has run without complaint since January). A broader mandate would significantly increase the number of Orgaworld’s potential clients in eastern Ontario.

Peter Hume, the Ottawa councillor who pushed through his city’s green bin program in the face of major political hurdles, is fighting Orgaworld over that bid; the last thing he needs is voters getting sick to their stomachs. Orgaworld appears undeterred. “We’ve invested almost $30 million in London and almost $24 million in Ottawa,” says Janssens. “We’re planning to invest far more.”

    I wonder if they aren't taking on more than they can chew with disposable diapers and pet waste. My municipality has a green bin program, but it isn't as comprehensive as Toronto's – basically food waste and paper towels / napkins only. No plastics, either. Compostable bags only. The composting operation is run out of a nearby city and I haven't heard a word about odour problems or issues with the end product.

      "I wonder if they aren't taking on more than they can chew with disposable diapers and pet waste. "

      I take your point, but that metaphor has serious problems.

        Oh, I don't know about that. Some composters use 'digesters.'

    I live in Halifax Regional Municipality. We've had a green bin compost program for many years. We are only permitted to put in food waste, paper towels, napkins, including non-corrugated boxes. No smell complaints. Newspapers go into a either grocery bags or blue bags. Corrugated boxes are tied or taped and are recycled separately as are certain PET plastics, plastic bags and anything metal like tin foil, etc. Any metal items end up being collected by people who drive around, usually in old beat up trucks, before the garbage collectors arrive. Last week, however, I saw a guy with a newer model minivan, remove the metal legs and frame of a patio table with a battery charged screw driver. Enterprising lot. Not sure whether it's illegal, but probably. It's apparently illegal if people collect containers, for which the purchaser has paid a deposit but hasn't returned to the recycling depot to get a partial refund on the deposit. The city wants to benefit for the unclaimed deposit. Typical.

    Offer a profit incentive (inscentive?) for odorless waste control and it will happen. Currently the only incentive is that residents may complain in such numbers that politicians force the plant to close. That's pretty indirect.

    How about dividing the tax revenues from the plant among the local residents, and allowing locals either to accept the payment, implying approval of the operation, or reject it. If they choose to reject it, the plant pays double (or triple) that person's portion to the government. This way the residents effectively become customers of the plant, with the ability to refuse to purchase if they don't like what they're getting.

      Encouraging an improved environment through a progressive tax structure?

      • http://intensedebate.com/people/Gaunilon Gaunilon

        Of course! But "improved environment" in my view means incontestable benefits like odor and health, not dubious ones like a reduction in atmospheric CO2.

          Why should the law-abiding owner-operator of the plant have to pay a punitive tax without due process?

    "Diapers, pet feces and plastic bags" have little or nothing to do with Orgaworld's odour problem. Diapers and pet feces have been accepted and composted successfully elsewhere. Plastic bags, biodegradable or not, are a nuisance but are not the basic cause of the problem. The real problem with the plant and the operation is that they are fundamentally flawed.

      yeah, i agree, when our home compost-er starts to smell, it is because the stinky anaerobic bacteria are taking over. A thorough stirring and turning fixes the problem right away, we turn the mix at least once a week we get about 4 or 5 cu/ft of compost yearly .

      Our nearest municipality had this problem and it was the same solution;, aeration, but on a grander scale.
