Research Title: Transformation of Greenhouse Gases into Sustainable, Biodegradable Microbial Plastics

Research Description: Reducing adverse effects of plastic pollution and climate change requires transitioning away from our global fossil fuel-based economy. Safe and effective utilization of greenhouse gases (GHGs) such as carbon Photo of graduate student Jorge Meraz in the lab, working with a long, tube-shaped device.dioxide (CO2) and methane (CH4) is increasingly important, as they are ubiquitous and reliable sources of feedstock for bioplastic production. Type II methane oxidizing bacteria (MOB) can use CO2 and CH4 to produce environmentally-safe bioplastics. While growth substrates are widely available, current designs limit growth efficiency and pose explosion risks from mixing combustible gases. Jorge will combine the fields of environmental biotechnology and materials science to develop the innovative reactor design and process engineering required to increase safety and maximize biomaterial yield and reduce climate change effects.


Jorge is an analyst at PG&E, where he conducts research and analysis on emerging technologies to plan for California's transition to clean energy.
