A new study shows that systems designed to capture methane from cow manure, called dairy digesters, are highly effective. But on the rare occasions they fail, the leaks are large enough to offset ...

A new study from the University of California, Riverside offers a nuanced assessment of dairy manure digesters, finding the systems significantly reduce methane emissions overall but can lose much of ...

A California state grant program designed to reduce greenhouse gas emissions results in the direct release of approximately 225,000 to 300,000 metric tons of carbon dioxide into the air each year, ...

Nine electricity-producing methane digesters are under development throughout the state despite initial financing hurdles. Digesters, located on dairy farms, convert manure into electricity by ...

They are some of the dairy industry’s anaerobic digester pioneers, the inno-vators who have taken steps—no, leaps—to create renewable energy, improve manure management, produce cow bedding or simply ...

One of California's biggest sources of methane pollution — its massive dairy industry — operates almost entirely without regulation. In fact, not only do the state's largest dairies face no penalties ...

A biogas site producing around 1,000 Nm3 per hour contains enough methane to support ammonia output measured in tens of ...

Low concentrations of caustic soda (sodium hydroxide, NaOH) are more efficient than high doses for preparing organic waste for biogas production. This finding increases methane production, reduces ...
