Methane digester

#3. "Methane Digester". Marshall, CA. The single largest source of pollution in the State of California is methane from cows. At Albert Straus’s family dairy a methane digester traps methane before it can enter the atmosphere, breaking it down into solids and liquid fuel that can be used to provide enough electrical power to run the entire dairy operation.

Methane from grass clippings has been happening on my farm for the last 9 years. You can see an earlier post of the experimental system. Interest is finally picking up, even though few believe the hot, blue flame on the stove is methane when they see it. I thought it might be helpful to run some numbers passed the unwashed on this subject. Costs per kilowatt of electricity in Texas are fixin’ to rise. There’s no real reason just now to hike the cost since they’ve been pumping out…

conceived by a group of teenage girls, the machine separates hydrogen from urine to provide six hours of electricity from a generator.

Clean energy is sometimes touted as space-age technology. Some of the principles, however, can be pretty darned simple.

Story at a glance The Environmental Protection Agency just awarded Ohio University nearly $200,000 to go toward a project aimed at reducing methane emissions. The project would target food and brewery sectors near the university using a process called anaerobic digestion. Anaerobic digestion uses microorganisms to break down organic material. The U.S. Environmental Protection Agency…

In the book Another Kind of Garden, the methods of Jean Pain are revealed. He spent his entire short-lived life studying brush land and forest protection, specifically fire prevention, alongside his w

Biogas is a gaseous fuel containing large amounts of methane (biomethane) which is produced by the anaerobic digestion of biological material under controlled conditions. Please fill in the form with as much as information so … Continued

It’s a misunderstanding that methane emissions come from the back end of cows. Fortunately, they are burped out, which means we can target the start of the digestive system to find ways to reduce emissions. The DairyNZ experts in this video are researching how forages like plantain may help reduce the amount of methane in cow burps. Question for discussion: What causes cows to produce methane?
