We are currently working on creating biochars from various biomass waste sources including food waste. We are also looking how biochars can be used for energy, as a soil amendment, and as an adsorbent for pollutants like CO2.

In the production of biochars, we have looked at a large variety of biowaste including nut shells, coffee grinds, spent grain from breweries, and corncobs. We have found that lignin content and ash content both impact how quickly the pyrolysis reaction proceeds. We have found that the impact of the inorganic content also impacts the reactivity of the biochars for subsequent gasification reactions. Here is a video of Derek and Delphine showing their leaching process to study the impact of removing inorganics on biochar reactivity.
