The United States Department of Agriculture (USDA) and the Federal Aviation Administration (FAA) have teamed up on a 5-year Memorandum of Understanding, for the development of aviation biofuels in the country. The feedstocks considered for jet biofuel development are forest and crop residues. In order to achieve the objectives, the two agencies will: (1) "bring together their experience in research, policy analysis and air transportation sector dynamics to assess the availability of different kinds of feedstocks that could be processed by bio-refineries to produce jet fuels", and (2) "develop a tool to evaluate the status of different components of a feedstock supply chain, such as availability of biomass from farms and forests, the potential of that biomass for production of jet fuel, and the length of time it will take to ramp up to full-scale production". According to the USDA press release, the cooperative agreement supports a larger research plan led by USDA through its five Regional Biomass Research Centers, and the plan sets out to include as many U.S. rural areas as possible to maximize the economic benefits of biofuel production across the country.
