Abstract: An in-vessel composting apparatus and process for continuous processing of food waste into an end product comprising a bulk organic compost material. The apparatus comprising a shredder/particle sizer feeding a horizontal drum having at least three chambers with connecting ports of sequentially increasing diameter, and through to a bulk collection container. The apparatus is further equipped with motorized drum rotation and provision for compressing and draining excess fluid from the incoming feed stock and then reintroducing it in the third chamber as needed to maintain suitable moisture level.

Abstract: An in-vessel composting apparatus and process for continuous processing of food waste into a two component end product consisting of a bulk organic compost material and a compost-rich, liquid tea. The apparatus consists of a shredder/particle sizer feeding a horizontal drum having at least three chambers with connecting ports of sequentially increasing diameter, and through to a bulk collection container. The apparatus is further equipped with motorized drum rotation and provision for draining excess fluid from the first chamber, holding a batch volume at elevated temperature for a period of time, and then percolating it through the finished compost product in the third or final chamber to make compost tea.

Abstract: An in-vessel composting apparatus for processing food waste and associated organic packaging materials, consisting of a shredder/particle size, and a horizontal drum with three chambers with connecting ports of sequentially increasing diameter, incremental drum rotation, and process control system.
