Stephanie Lansing

Dr. Lansing is leading two new grants totaling >$6 million from the U.S. Department of Energy (DOE) to develop sustainable products, such as biofuels and bioplastics from food waste. These grants are aimed at understanding the waste sources we have, particularly the quantities of food waste, and determining what opportunities exist for us to create renewable resources and energy from that waste. One grant is focused on the production of bioplastics from food waste, while the other is focused on characterizing the municipal solid waste stream to create biofuels that can replace liquid fuels like aviation fuel.
