Research Focus:

Dr. Li’s research focuses on the development of advanced technologies for the production of bioenergy and bioproducts from renewable sources which can be commercialized by industry partners. His current research covers four areas: (1) anaerobic digestion, (2) Biopolyols and polyurethane, and (3) algae.

Anaerobic digestion:  Dr. Li has developed an integrated anaerobic digestion system for bioenergy production from both liquid such as animal manure and solid organic waste such as crop residues and yard trimmings. This technology is currently patent pending. With the funding from US Department of Agriculture and the Ohio Third Frontier program, he is closely working with Quasar Energy Group for the pilot scale testing and demonstration of this technology in Zanesville, OH.

Biopolyols and polyurethane:  Dr. Li has developed a patented liquefaction process (US 8,022,257 for the production of biopolyols and polyurethanes from lignocellulosic biomass and crude glycerin (biodiesel byproduct). This project is funded by USDA NIFA and the Ohio Soybean Council. It has been licensed to Bio100 Technologies LLC in Mansfield, OH for commercial production.

Algae:  Dr. Li has developed an integrated system for algae production using anaerobic digestion effluent as a nutrient source. The algae biomass residue after lipid extraction will be sent back to the anaerobic digester for biogas production. This project is funded by US Department of Energy. He is working with Touchstone Research Laboratory for pilot scale algae production and demonstration on Cedar Lane Farm in Wooster.
