San Francisco's answer to dog waste problem.
To paraphrase, San Francisoco has a big animal waste problem. Acording to stats in this article pet feces makes up almost 4% of household waste. 6,500 TONS of dog poop is produced in the San Francisco Bay Area.
Quote from this article "The poo-to-energy scheme works like this: the pet poop is first put into an anaerobic digester, which uses bacteria to convert organic waste into methane gas. Burning that gas produces energy in the form of electricity, natural gas, and liquefied natural gas. This gas is then captured and used to power equipment that normally runs on natural gas, such as a kitchen stove or a heater. The 2 week long “digestion process” also produces valuable compost for agriculture."
