Photos of Greenbelt Micro-Biorefinery Systems
Our "Micro-Biorefinery in a Can" consists of an integrated package of containerized energy, food and water systems that can convert: MSW, food wastes, FOG (fats, oils, and grease), wastewater sludge, paper and cardboard, wood and green wastes into:
• Renewable power generation using biomass and/or solar thermal and PV
• Tri-generation for heating, cooling and power for parasitic loads (CCHP)
• Compressed renewable biogas for vehicles and/or for CCHP
• Bio-ethanol for E85 and E95 for engines
• Clean water for recycling, wastewater treatment
• Aquaponics for vegetables and fish
Prosys develops innovative integrated high efficiency biorefinery systems that are designed for processing of locally generated biomass or waste feedstocks into locally consumed products.
Our micro-biorefineries are small-scale, end-to-end modular systems that have been engineered to produce commercially viable advanced bioethanol or bio-diesel. This proven technology can recycle food, beverage and other cellulosic wastes as feedstocks into sellable products: fuel, feed, fertilizer, and filtered water.
The Micro-Biorefinery technology offered by Prosys is a proprietary closed-loop process that converts harvested duckweed and micro-algae crops into high value concentrated protein meal and bio-ethanol as co-products. After the protein meal has been separated the remaining liquid, which is rich in starch, is then fermented and distilled into high purity alcohol as biofuel. Once the alcohol is made the thin stillage that remains is recycled back to the ponds as fertilizer to grow the duckweed.
Duckweed is grown in shallow open 2.5 acre (1.0 hectare) earthen ponds 1.5’ feet deep. A “typical” biorefinery project would require 320-acres with 110 growing ponds and a 4.0-acre fenced site for the processing plant. Each pond is divided into sections for harvesting every two weeks.
