Manure Digesters: Climate Fix or Risk?
Manure digesters are increasingly promoted as a solution to cut greenhouse gas emissions from dairy farming, but a recent analysis highlighted by New Scientist suggests their real-world impact is more complex. These systems use anaerobic processes to break down manure and capture methane—a potent greenhouse gas—converting it into biogas for energy. While they can significantly…
Methane leaks threaten dairy digester gains
A new study highlights that while methane digesters on dairy farms are largely effective, rare but massive leaks can erase much of their climate benefit, raising concerns about long-term sustainability. The research, led by scientists at the University of California, Riverside, analyzed 98 dairies across California over eight years using satellite and airborne data, tracking…
Suzuki unveils second biogas plant in India
Suzuki Motor Corp. has unveiled its second biogas plant in India, located in Bhukhala, Gujarat, marking a significant step in integrating dairy waste into clean energy production. The facility, opened in January, processes around 100 tonnes of cow dung per day and produces approximately 1.5 tonnes of biogas daily, which is converted into methane for…
