About
Our goal is to recover renewable energy, bio-based chemicals and agricultural nutrients from food production waste streams, while minimizing their carbon footprints. We combine fundamental and applied research to develop sustainable processes by integrating biological and thermo-chemical treatments to recover valuable resources from agricultural waste streams.

WasteDive tells our story
Research
Biomass to Energy
Most Waste-to-Energy technologies are still at an emerging stage with a lot of room for innovation. Process optimization requires fundamental research on each one of the conversion processes. An important step involves experimental research to identify chemical and metabolic pathways that will be essential to maximize conversion yields of biomass to biofuels for both thermochemical and biological platforms..
Upcycling of plastic waste
Accumulation of plastic waste is harming eco-systems and it is time to move towards a circular plastic economy. Sustainable production and recycling processes for plastics are challenged mostly by the lack of renewable building blocks. We investigate hydrothermal processing (HTP) as a platform for depolymerization of commonly used plastic polymers.
.
Nutrient Cycling
Holistic approaches to valorize waste streams seek to recover nutrients in a reusable form for further agricultural applications. Our lab seeks to better understand the fate of recycled nutrients and their incorporation into the complex plant-soil-atmosphere system.
Life Cycle Assessment
The development of sustainable and commercial-scale waste to resource systems must be supported by a life cycle environmental impact assessment to define research priorities. In addition, financing conditions, that would make waste to resource systems attractive, have to be determined. Specific parameters that account for uncertainties related to the development of these technologies will provide more useful information for investors and policy makers.
