Ottawa is starting up a citywide composting system, with pick ups every two weeks through the winter:
Starting Monday, and for the next 12 weeks, the city will be delivering 240,000 green bins and small, counter-top kitchen-catchers to households across the city.
The chief environmental advantage cited, reducing landfill usage, is not overly compelling. We have plenty of space for landfills, and they are very tightly regulated. I would be interested in knowing what the other effects of the program will be, if any, on factors like air quality, water quality, and greenhouse gas emissions.
It is interesting to note that the service will no accept ‘biodegradable’ plastics, because the term doesn’t have a standard usage and there is a risk that the compost produced would be contaminated.
