Abstract

This Small Business Innovation Research Phase II project will build, field test, and prepare for commercialization, a prototype industrial tub grinder with integrated high inertia flywheel technology that will reduce the consumption of diesel fuel in recovering woody biomass. Low-weight, high-inertia flywheel technology can significantly assist the diesel engine duty cycle such that more production can be had with the same amount of diesel fuel consumed. This will in effect lower the cost of grinding woody resources as measured by cost per ton. Each year in the United States alone, an estimated 157 millions of gallons of diesel fuel are consumed in the processing of recovering woody waste streams. The woody waste streams have value in the forms of renewable energy source for electricity co-generation, potential feed stock for cellulose ethanol, engineered wood products such as particle board and press-forms, compost, landscape mulch, and other soil amendments. The USDA estimates that only 5% of the total available woody resources in the United States are currently being utilized. It is expected that recovering woody resources will grow as a source of green, renewable, carbon neutral energy source in the future and hence the need to lower the cost of processing.
