Illustration of Greenhouse at Lebanon Landfill
Carbon Harvest Energy has a 20 year contract with the City of Lebanon, New Hampshire to design, build and operate the Lebanon Resource Stewardship Facility at the City’s active landfill. The first phase of the project will manage existing, vented landfill gas through a new gas collection system. Next a combined heat and power plant with a capacity of 1.6 megawatts will be added, and the electricity will be sold to the grid through a long-term power purchase agreement. The estimated 7 million Btu/hour of waste heat will also be recovered for use on-site in greenhouse-based agriculture systems as well as for a distributed heat system providing heat to nearby asphalt and concrete plants to offset the fossil fuel demands of their industrial processes.
The project includes an ongoing research partnership with Dartmouth College’s Environmental Studies Program, which includes lab and greenhouse research facilities at Dartmouth College. This research partnership focuses on the development of a sustainable algae-based tilapia feed program that will enhance the omega-3 fatty acid content of the fish and to provide a sustainable, non-animal based substitute for fish meal.
A 21,000 s.f. hard-shell greenhouse is also proposed at the Lebanon Landfill as a near-future phase and will house an aquaponics operation incorporating 100,000 gallons of aquaculture. Greenhouse products will be sold to Dartmouth Hitchcock Medical Center and Dartmouth College, with the remainder going to our distribution and marketing partner, Upper Valley Produce. Additional plans are being developed for a multi-acre (3 to 5 acres) algae grow-out facility.
