The estimated amount of poultry litter produced annually in Alabama is over 1,250,000 tons. This large amount results in significant litter management challenges. Currently, poultry producers are facing many regulatory issues and challenges with respect to environmental impacts of litter management. Commercialization and implementation of environmentally benign biorefinery technologies have the potential to generate electric power (including on-site power) and heat as well as transportation fuels, hydrogen, valuable chemicals and fertilizer from poultry litter economically while addressing environmental problems caused by traditional disposal practices.

In this study, poultry litter generated annually in Northern and Southern Alabama was documented on the basis of published literature and transportation cost of poultry litter is minimized for both North and South Alabama by the selection of the best large scale biorefining facility location and optimal feedstock allocation using mathematical optimization techniques.

The availability percentage of existing poultry litter feedstock for a large scale biorefinery is found to be an important factor in transportation cost. It is found in this study that transportation cost increases several fold as the local feedstock availability for biorefining reduces from 100% to 50%.

Optimum facility locations for both North and South Alabama were found within a 10 mile radius for three different poultry litter feedstock availabilities.
