CleanTech Biofuels, Fiberight to Create Municipal Solid Waste to Cellulosic Ethanol Demonstration Plant

CleanTech Biofuels, Inc., an early stage provider of cellulosic biomass feedstock derived from municipal solid waste (MSW) for energy and bio-based chemical production, will install its demonstration vessel at Fiberight LLC’s cellulosic ethanol pilot plant in Lawrenceville, Va. This combination of CleanTech’s patented Biomass Recovery Process and Fiberight’s Targeted Fuel Extraction process will create a fully-integrated MSW to cellulosic ethanol demonstration plant.

This agreement advances the Companies’ July 2009 Joint Research Agreement, which established anticipated yields and operating costs of using CleanTech’s cellulosic biomass feedstock in Fiberight’s Targeted Fuel Extraction process. Under the terms of the agreement, Fiberight will finance the transfer of the vessel, equipment upgrade, and all operating costs associated with running the vessel at the Lawrenceville plant.

Additionally, CleanTech will have access to biomass produced at the Lawrenceville plant for delivery to companies interested in testing it as feedstock in their conversion technologies.

CleanTech Biofuels’ Biomass Recovery Process uses steam and pressure to separate and clean municipal solid waste into high-quality biomass, capturing recyclables at the same time. When removed from the process vessel, the cellulosic material is sorted from the recyclables and other garbage contents using shaker screens.

The cellulosic biomass falls through the screens. The recyclable materials are recovered and the remainder, less than 20% of the total input, is sent to the landfill. The process also removes a sustainable amount of the volatile organic compounds (VOCs) avoiding their release into the atmosphere.

Fiberight’s TFE process recognizes that sold waste is neither homogeneous nor fully convertible to energy. Fiberight has developed a system that bifurcates organic and inorganic wastes and converts them according to type. Fiberight’s TFE process separates, cleans and processes organic and hydrocarbon fractions then converts the organic fraction into cellulosic biofuel, the hydrocarbon fraction into plant energy and electricity, and the inert fraction into recyclables or beneficial products. Enzyme recycling and cellulosic sugar concentration technologies. The company brought a pre-commercial plant in Blairstown, Iowa on line in May.
