Recycling food waste through composting and anaerobic digestion has the greatest potential by far to reduce the quantity of food waste going to landfills over the next 15 years relative to food waste reduction and reuse, according to ReFED. However, as more cities and states institute landfill food waste bans and other programs to promote recycling, the demand for centralized organic processing facilities is outpacing the supply. To address the gap, vendors are actively marketing to commercial customers new onsite pre-processing systems, including dehydrators, pulpers, and biodigesters. The systems can save money by reducing or eliminating off-site hauling of food waste and are well suited to facilities short on space and staff time. But the question arises: are the nutrients and energy in food waste really being recycled? The answer depends upon the next stage of processing.
