Briquetting a Better, Burnable Cow Patty

Chris recently served as a technical advisor to Rose Marie Belforti on her recent NE-SARE funded project to demonstrate a hydraulic press used to make fuel briquettes from manure and bedding.  The machine, dubbed the “Biomass Beast” by Rose, was built for $5,766 and Rose demonstrated production of briquettes at a rate of 90 dry […]

Vermont Farmers Food Center Heats with Biomass

UVM Extension and others supported the recent installation of a 341,200 BTU/hr (output) multi-fuel biomass boiler at the Vermont Farmers Food Center (VFFC) in Rutland, VT.  The boiler heats the Farmer’s Hall building with the capability to use several alternative fuels to displace propane. The boiler was fueled primarily on wood pellets but was also […]

Grass and “Ag Biomass” Competitive with Wood Chips

Recent testing at the Meach Cove Trust has demonstrated strong economic and technical feasibility of grass-based biomass combustion fuels.  The use of solid, densified, cellulosic biomass fuels has been well demonstrated with wood pellets in residential and light commercial systems and wood chips in larger, often centralized systems.  The Grass Energy Partnership of the Vermont […]

Oilseed Economics Update 2014

Yesterday we held our annual Oilseed Producer’s Meeting.  At this meeting, I presented an economic overview of oilseeds in Vermont.  Ina nutshell, Vermont has an installed on-farm biodiesel capacity of 600,000 gal/yr (5 sites) with a normalized initial cost of $1/gal of capacity (better than national average). Fuel can be produced for an average cost […]

Vermont On-Farm Biodiesel – Costs of Production

I recently co-authored a summary of the economics of on-farm biodiesel with Netaka White from the Vermont Sustainable Jobs Fund.  This report collects the economic and logistic learning from the past seven years of the Vermont Bioenergy Initiative (VBI).  The VBI has supported a wide range of sustainable fuel related efforts in Vermont.  Along with […]
