According to Metro Vancouver’s waste surveys, 40% of household waste (by mass) is compostable organics. That means, of the average Metro Vancouver household’s 834kg of annual garbage, about 334kg is organic material that will compost. Notably, some organics, like fabrics and leather, do not readily compost, so they are not included in this 40%, nor are things like paper that do compost, but are classified under “recyclables”.
The vast majority of the rest of what goes to the curb is recyclable through the blue-box program or through the City’s recycling centre. Therefore, through recycling and composting, we can significantly reduce the amount of trash that goes to landfill or WTE. Every kilogram of trash we divert from the garbage truck, we save tax dollars used to pay tipping fees to dispose of the trash, we save the expense of moving garbage about, we reduce the need to burn diesel, we reduce the negative environmental impacts of trash incinerators and landfill leachate, we save landfill space. So can we agree that indiscriminately throwing trash to the curb is not a sustainable activity?
However, not all compostable organics are suited for the back-yard garden composter. Things like meat, bones, milk products, and fat get really stinky as they rot, and attract rats and other pests. They also encourage the production of methane, or sulphur compounds that we generally want to avoid both for the ecosystem of the compost, and for greenhouse gas reasons. Weeds like chickweed or creeping buttercup, when placed in your garden compost, will spread to new areas of your garden when you apply the compost. Therefore, the traditional backyard compost (where most of my kitchen scraps go) is unsuited for these wastes.
We have three options to manage this stuff not suited for the traditional garden compost:
Option 1: We put it in our new Clean Green Organics bin, provided by the City. The City then takes this material and ships it to a commercial composting company. There the material is shredded and composted in a high-oxygen environment, to reduce the production of methane and sulphur gasses, and is made back into commercial-grade compost, used mostly in parks and other City gardens. The reason the City does this is simple: they pay about half the tipping fees for this material than they do for “regular” garbage going to the landfill or incinerator. Therefore, your garbage utility tax goes down.
3: we do what Conservatives always suggest: we take personal responsibility for our own situation, and instead of relying on the “nanny state” or the “suffering taxpayer”, we simply install a Green Cone in our back yard and throw the small proportion of organics that would foul our composter into there instead. We remove the personal need for Clean Green Organic waste collection, we reduce the collective need for expensive incinerators or landfill technology, we save the poor, beleaguered taxpayer money.
All for the price of about 10kg of plastic. Oh, and the Green Cone is made of 100% recycled plastics, and is 100% recyclable with today’s plastic recycling technology. “Anonymous” suggested it would be destroyed by the sun within 8.3 years, but it is guaranteed for 10 years, and there are many of them out there in the world that have been functional for more than 20 years.
Again, I like the math of the Green Cone. It looks good on paper. However, part of the purpose of my having one is to evaluate how useful and practical it really is. I will report back.
