Food Waste Depackaging Systems
Packaging output from a Dupps-Mavitec food waste processing unit.

Newer models separate packaging with the least amount of applied force necessary to avoid splintering of the packaging. Depackager options are described.

Facilitating Food Waste Digestion
Dry fermentation digester at Blue Line Transfer processes about 11,000 tons/year of residential and commercial food waste and green waste.

Increasing volumes of commercial food waste, much of it contaminated or packaged, led digestion facility in South San Francisco to install a depackaging unit.

Depackaging At Solid Waste Transfer Station
Storage area for packaged dry foods such as bread and cereal, to be loaded into the Scott Turbo Separator, and recovered for animal feed. An entire pallet of packaged food, inside a large cardboard box, can be tipped into the hopper for processing.

A Massachusetts trash hauling and recycling company invested in a mechanical separation system for food waste, opening up outlets for the processed material.

Depackaging Feedstocks For Anaerobic Digestion
Biogas Energy Partners accepts packaged food waste from food processors, retailers and institutions. A depackaging unit installed in July is designed to process 150 tons/day.

Mechanical and hydraulic techniques are used to break open packaged feedstocks and separate them from the organic material.

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.
