Project Title: Bioenergy Production from MSW by Solid State Anaerobic Digestion
Project Description: Solid-state anaerobic digestion (SS-AD) is a bioenergy production technology characterized by a high solids content (15-30% solids). It is widely used in Europe to produce biogas from the food and yard waste; however, to our knowledge only one commercial scale SS-AD facility is currently operating in the US. Advantages of SS-AD include faster waste degradation and higher biogas quality than conventional or bioreactor landfills, lower water use and leachate production than wet anaerobic digestion technologies and production of a nutrient rich fertilizer. The overall goals of this project are to evaluate the potential for SS-AD in Florida and to improve the rate of biogas production during co-digestion of the organic fraction of municipal solid waste (OFMSW). Specific objectives are to:
- Evaluate the most appropriate technologies for implementing SS-AD of OFMSW in Florida,
- Carry out fundamental research at bench- and pilot-scale to improve the biodegradability of lignocellulosic waste through co-digestion with pulp and paper waste sludge,
- Identify potential sites, collaborators and funding sources for a large scale SS-AD demonstration project in Florida.
Results from this project will be disseminated widely to a variety of stakeholders including FDEP, USEPA and county regulators, county solid waste directors and their staff, private waste management companies and other associated industries, university and K-12 students, engineers, operators, scientists and community members.
