Carbon Harvest is just starting to work with the City of South Burlington to develop a project that will collect biogas from the landfill, wastewater treatment plant and a new biodigester and use it to generate approximately 500 kW of electricity to the grid. To learn more about this project, link to video of Don's October presentation to the South Burlington City Council, courtesy of CCTV.

Landfill Gas-to-Energy Plant
With broad community support including the Windham Solid Waste Management District, Carbon Harvest Energy is launching the country’s first integrated renewable energy-to-agriculture and algae feed and biodiesel project in Brattleboro Vermont. Demonstrating complete capture and beneficial reuse of landfill gas, a potent contributor to global warming, Carbon Harvest Energy is restoring the former landfill gas-to-energy project at the Brattleboro landfill, which will supply 250 kW electricity to the grid (see recent photos of the project). Once this power plant is operational, Carbon Harvest will install an additional, state-of-the-art combined heat and power (CHP) generation plant (310 kW electricity).

Greenhouses and Aquaponics
Next Carbon Harvest will build a 20,000 square foot greenhouse with aquaculture and plant production for year-round, high quality fish and fresh vegetables to supply the Vermont Foodbank and other customers. Waste heat from power generation provides low-cost heat to the greenhouse, and 30,000 gallons of aquaculture provide high value organic nutrient for the plants (aquaponics) as well as the algae culture project. High winter heat demands of the greenhouse are balanced by high summer heat demands for algae processing, so all heat value from the CHP generators is fully utilized.

Algae Biodiesel and Feed R&D
In partnership with the University of Vermont’s Rubenstein School, combustion exhaust from the CHP plant and waste from the aquaculture facility will become the nutrient for an algae research and development project which will capture all remaining waste and carbon and convert it to algae for production of biodiesel and livestock feed for fish and poultry. This zero fossil fuel input, zero waste output facility will remove approximately 20,000 metric tonnes of carbon per year and convert this greenhouse gas to high quality local food, biofuel and feed while producing virtually zero waste.
