Poop Power
Converting dog waste into light

If you’ve been reading Bark’s blog for any length of time, you know my pet peeve is dog waste. I hate wrapping it in plastic and adding it to the landfill almost as much as I resent people leaving it on the street and in the park. So I LOVE lemons-to-lemonade/sow’s-ear-to-silk-purse stories that start with this all too bountiful raw material.

Therefore, howls of gratitude to Cambridge, Mass., artist Matthew Mazzotta who has created a dog-poop-to-methane converter that fuels a park light, known as the “Park Spark.” Mazzotta has succeeded where others, including the City of San Francisco, have failed.

I've been seeing these and I think they're wonderful.

At our local dog park, dog waste is composted. But I'm still trying to find a good solution for every day walks. My yard doesn't have appropriate soil for a doggie digester.

It seems like the best way to get rid of dog waste is to flush it down the toilet. But how do you get it home to the toilet from a walk? I think we need sewage system safe baggies that can be flushed down the toilet. I've been looking for such a thing but have never seen it.

Pamela, I haven't tried this (and I don't work for the company), but it looks like a good product:
