Proposal for Biogas Capital Improvement Project
Thanks for the attention to the subject of energy from biogas. Following is a brief explanation of using landfill gas (LFG) and biogas from local organic waste.
The 2007 feasibility report projects LFG from the Ukiah landfill to be 300 cubic feet per minute for the next ten years. It will slowly decrease to 200 cubic feet by 2023. We contacted national experts who proposed biomass gasification for increasing power potentials. Gasification of biomass is not burning at all nor producing any more methane gas, rather is it an instant hot smoke gas extraction. All emitted gasses are completely absorbed, filtered and compressed. The process of gasification is automatic, extracting first water vapors then volatile gasses with heat. Using the exhaust heat from the electric turbine generators, gasification has no smokestacks and a relatively small physical footprint. In a closed loop cycle, no new additional pollution is created. The gasified material is left as agrichar, a clean soil amendment. The process purifies the carbon by heat. It qualifies for carbon credits. Distilled hot water is another byproduct.
Since LFG is bound to its location, a good site for a gasification plant is at the old dump on the existing concrete slab. The LFG can then be mixed with the biogas as additional fuel. Biomass material for gasification is all locally available; it includes: biosolids, tree trimmings, agricultural and yard waste (currently burned.) At the moment, Ukiah pays for transporting its biosolids from the waste water treatment plant to “Redwood” in Marin for landfill. Cost and pollution can be redirected.
