Anaerobic digesters have become a useful tool for some dairy farms to not only manage their manure and environmental impact, but also to create another source of income by selling the power that is generated. In a growing number of states, that opportunity may become more feasible and attractive as food retailers and distributors must explore ways to divert their food waste.
Waste from human food production and consumption is already processed in digesters around the country, often to help smaller dairies that generate less manure keep their digesters running efficiently. Of course, the technology is also a valuable way to reduce some of the impact of the thousands of tons of spoiled and discarded food destined for landfills.
