Depackaging Feedstocks For AD And Composting
A1 Organics purchased the Ecoverse Tiger HS640 Food Depackager, which has an 8 cubic yard stainless steel hopper that can be fed with a loader (above). Material is pulled into the vertical mill by augers in the bottom of the hopper; bolt-on paddles, spinning at 1,000 RPMs, remove organics from their packaging. Examples of feedstocks processed include cardboard-packaged dried dog food (in loader bucket above), expired dairy products (bottom left) and gallon jugs of iced tea (bottom right).

Digester preprocessing system to be installed by A1 Organics at the Heartland Biogas anaerobic digester in Weld County, Colorado, includes two types of depackaging units.
