Joseph Gallo Dairy & Cheese Plant's methane capture provides 80% of the electricity for the plant from 5,000 cows. The farm uses waste water from the cheese plant to flush the manure from the cattle stalls. The solid manure is removed and the remaining liquid containing bacteria from the cow manure is pumped into a covered digester (pond). This bacteria releases methane that is then used as fuel for electric generators.

A similar anaerobic digester is being used by the UC Davis Biogas Energy Project to divert food waste and yard clippings from landfills. Instead the organic biomass is being used to create alternative renewable energy. View the fullsize video.
