Manure and Food Waste
RCM's Plug Flow Digester is an unmixed heated rectangular tank that digest raw livestock
manure (11 - 13% solids) from dairy farms only. Livestock manure is collected by scraping and
enters the digester. Manure degrades as it travels through the tank. An impermeable material
covers the top of the rectangular tank in order to capture the biogas.
