Waste-to-energy is a heated topic these days…

Waste-to-energy is a euphemism for incineration, which is that process where a plant will burn municipal solid waste using thermal treatment which in turn can be used to generate electricity. At the “Waste-Based-Energy” industry conference in November 2009, delegates learned about several new incineration plant proposals including one in the Durham/York Region (not too far from Peterborough). The facility’s price tag is roughly $272 million and will be operated by New Jersey based Covanta Energy Corp.

There are some advantages to this plant that I should note. Considering the large population growth of the Durham/York Region, and given the implications of their growing electricity demand, the incinerator could very well provide electricity for thousands of homes. It could also be a solution for neighbouring municipalities who are currently stressing over their landfill sites due to overuse and leachate problems (i.e. when a lot of organic wastes end up in the landfill, sometimes they can leach from the landfill carrying other toxic wastes into the groundwater supply). Other parts of Canada including Metro Vancouver, Ottawa and Edmonton are all on the path to building more incinerators, many of which are being done by public-private partnerships.

So, I have touched on the “good” and now I turn to my cynicism and pessimistic take on the proposed incinerator. Firstly, there are numerous health issues associated with incineration. The burning of waste releases thousands of toxic emissions implicated in asthma and respiratory illnesses, autism, dyslexia and Parkinson’s disease just to name a few. These sites are often built on Greenfield sites or in agricultural communities thereby eroding the viability of the farmer’s land and well-being. Tens of thousands of tonnes of toxic ash are generated annually from the burning of waste, and o yeah, that ash is often sent to the landfill.

These sorts of projects are highly controversial because the companies that operate them do not often account for their negative externalities. For example, when these plants spew out toxic emissions, those living within close propinquity suffer great respiratory illnesses. Indeed, the Durham/York Region is growing tremendously and an incinerator is bound to pose health issues which can potentially add even more pressure to a health care system that already has too much.

I think the Province should mandate that all new incinerators built in Ontario have “scrubber systems”. These systems are a diverse group of air pollution control devices that can be used to remove some particulates and/or gases from industrial emissions. This would account for some of those externalities and put the accountability right on the company that operates the plant.

Finally, the plant is proposing to have a $140 per tonne tipping fee (the charge for accepting waste at the site). I think that 50% of this fee should go directly towards the region’s recycling and composting programs. This would be imperative because empirical evidence suggests that when a city sees the construction of an incinerator, there is less of an incentive for keeping a well-maintained recycling system because incinerators are expensive! Also, taxpayers pay for them.

Key message: Companies that run these incinerators must be held accountable for their emissions. Indeed, they should be required to have mandatory scrubber systems to really minimize the health impacts of emissions. Our health care system is already stressed, let’s keep our innovative waste management programs like recycling and composting which pose no real health effects, unlike incineration.
