California’s dairy farms have long powered human bodies through milk, cheese, and other nutritious products. Now those same farms are helping to power machines by producing renewable fuels through innovative projects and programs that also help improve the state’s air quality. Like many farm animals, cows produce a lot of manure. The traditional way of handling manure is storing it in ponds or lagoons before the nutrients are applied to fields of feed crops. The anaerobic conditions of manure lagoons are ideal for generating greenhouses gases, in particular methane. However, anaerobic digestors increasingly being used on California family dairy farms can transform that methane into clean, renewable natural gas, electricity, and even hydrogen fuel. More >>
