About U.S. Sustainable Energy Corp.

U.S. Sustainable Energy offers a revolutionary new energy process that creates three times more fuel per feedstock unit than any other biofuel process. The company has engineered the first bio-renewable fuel able to serve as a replacement to diesel, with none of the negative traits associated with competitive green fuels. The USSEC biofuel is furthermore created at a nominal cost as the byproduct of producing organic fertilizer from recycled waste products, a discovery made during research into agricultural biomass now known as the "Rivera Process." The technology offers a solution to foreign oil dependence, significant reduction to the cost of electricity and ethanol production, and the eventual reversal of greenhouse gas emissions.

Management and current operations are focused on leveraging the superior performance and low cost of the fertilizer, biogas and biofuel within bundled plant operations, turnkey energy contracts, ethanol production, and other critical applications that rely on energy as a major cost component.
