The Wright Biodryer technology is designed to convert (through biological drying) various wet organic wastes and materials (food, biosolids, SSO, manures, wet distillers, grain, wood, paper, mill sludge, agricultural, etc) into a dryer, higher heating value biomass fuel (5500-7500 Btu/lb) without the use of fossil fuels (natural gas, etc) like traditional dryers (rotary, steam, etc).

The biomass fuel can then be used to create renewable energy in the form of heat, steam, power or ethanol through standard direct combustion, gasification, cofiring or calcination processes. This technology can also help clients meet their Renewable Energy targets while helping to reduce GHG’s (diversion of organics from landfill, displacement of fossil fuels) as well.
