The Race is On! Speed Composting is a Go!

- Adam Clare

One person’s trash is another person’s treasure. Or in reality, our waste from consuming can be repurposed and turned into useful resources.

If anyone knows that there’s value in trash, it’s Waste Management — the big waste hauler collects 66 million tons of it every year. So the company has teamed up with a small venture-backed company that has developed a system that can break down some of that trash fast and turn it into natural gas, electricity, compost or all of the above, making some of that trash even more valuable.

Waste Management announced today it has invested in Harvest Power and will develop projects with the company. Harvest builds giant digesters — think of them as cow stomachs — that speed up the composting process. By creating conditions that the bugs that break down organic matter thrive in — a little warmth, a little moisture — and mixing it up to keep the process going, Havest can speed the natural composting process to six to eight weeks from double that. The output? No hamburgers, milk or leather, but otherwise the same as what you’d get from a cow: natural gas and good fertilizer.

How to Stop Shopping

One reporter has joined a growing movement of people who have sworn off buying new things. It’s a good read and a good introduction into how one can change their shopping habits to help our friendly planet.

Here are the ground rules: No buying anything new, with three exceptions – food, booze and health essentials, like medicine and toilet paper. Mary-Margaret suggests we could use leaves, but I think she’s joking.

Also accepted: Second-hand purchases. Value Village, Craigslist, vintage shops are all fair game, as the official point is to lighten our environmental load. We are in Planet Saving Mode, not Shopaholics Anonymous.

It’s an easy case to make after the stuff-gorging of Christmas. Torontonians, on average, throw 3.7 kilograms into the household trash each week – not including compost or recycling – according to city statistics. And for every garbage bin we pack, another 70 were filled to make the stuff we’re throwing out, according to American garbage guru Annie Leonard.

So, by boycotting new things for three months, I personally will keep more than 900 bags of garbage out of landfills or incinerators around the world. Not to mention the coal-fired electricity involved in making the stuff, the truck fumes, the mining and logging …

Solar Powered Trash

- Adam Clare

trash binBoston has got some new trash receptacles on their sidewalks that are solar powered trash compactors. It means that more trash can fit in a box without costing the city, the city might even be able to save money because the bins don’t need to be collected as much. This is a yet one more neat use of solar power.

“Developed by a Jamaica Plain inventor, they are powered by photoelectric panels, which supply power to motor-driven compactors inside. Workers extract neat, 40-pound trash bricks instead of trying to manhandle the messy contents of an overflowing can.”

Boston is not the first city to use this technology though. There are bins located in Vancouver; Cincinnati; Queens, N.Y.; Needham; Newton; and Worcester. What city is next?

A novel use of the sun, however, they still need some work as “some people downtown mistook them for mail drops or traffic-light switch boxes.”
