VOICED : US farmers turn cow poo into power and profit

Homestead dairy uses anaerobic digesters to convert cow waste into methane, generating electricity for 1000 homes. This process offers benefits like sustainable electricity, nutrient management, and odor reduction. The US has potential for biogas recovery on 8000 farms, but only 250 have invested. Digesters provide economic and environmental advantages, including improved fertilizer quality and reduced groundwater contamination.

What potential does the US government estimate for livestock farms in terms of bio gas recovery?

What is one advantage of using anaerobic digesters over open pools for manure storage?
