Illuminating Pretreatment Systems: Liquefiers, Biodigesters, Dehydrators, Accelerated Composters
Join us for the Composting Collaborative’s November webinar that will explore the wide and very diverse family of pretreatment systems. Pretreatment systems include technologies that size-reduce food waste, often using enzymes or microbes and heat. We’ll examine the findings of the Composting Collaborative’s forthcoming directory of pretreatment systems and dive into case studies of individual technologies, as well as an analysis of the benefits and concerns of these technologies and how different cities have approached the influx of pretreatment systems.
