Wet Waste Recovery

A system that collects and liquefies food residuals for composting or digestion (Rothenburg Wet Waste Recovery), is being marketed by Ecology LLC. Supported by a grant from the Wisconsin Dept. of Natural Resources, a unit has been installed at Pandl’s restaurant in Bayside, Wisconsin. From a kitchen input station, waste is transported by vacuum to a mechanical device where it is chopped and slurried, then hauled to recovery sites. Program partners beside Ecology LLC include: Marquette University (analyzing samples for nutrient content); Milwaukee Metro Sewerage District (testing suitability for producing electricity); United Water Services (integrating into biomass equipment); Microgy (testing material in farm-based biogas system); Growing Power (using waste for composting and vermiculture); and Onyx Services (testing residuals for transport and field spreading).
