Anaerobic Digestion of Animal Wastes: Factors to Consider
Some Massachusetts dairy farmers are combining manure with food waste to produce renewable energy, reports PBS. Dairy farmers are diversifying their operations, working with a renewable energy company that builds anaerobic digesters on their farms. The digesters not only help farmers manage manure, but also take in food waste from the surrounding area. Unsold produce, spent distillers grains, and food-processing waste are trucked to the farms, ground, and used to produce energy for the farms and surrounding communities. The feature notes that a state ban on food waste in landfills and renewable energy incentives helped launch the operations and make them economically feasible.
