Bay Area Science Events

Come to the permaculture guild gathering to hear David House present on home scale biogas. Come for networking and food/seed sharing before and after.

Biogas, sometimes called “the cousin of composting,” is what you get when any organic material decomposes in the absence of oxygen (aka it’s anaerobic, vs composting which is aerobic). Biogas is made largely of methane, which is chemically identical to natural gas. Because of this, biogas is sometimes called renewable natural gas. In other words, it’s 100% natural, renewable energy from waste!

This talk is about how to build an entirely new type of “anaerobic digester” – a device that makes biogas, and a nutrient-rich slurry that works well as an organic fertilizer (used by organic farmers in Europe for decades). What’s new about this digester is that it can be built very cheaply, with materials entirely from Home Depot (or a similar store), and will work in cold climates, year-round.
