Senior environmental engineering students work on making biochar from corn cobs
Three senior environmental engineering students produced biochar from corn cobs as part of their senior design project. Biochar is a carbon-rich product that is produced from organic material subject to high temperatures in the absence of oxygen. It can be used as a soil amendment and to remove contaminants from drinking or storm water. The goal of their project was to evaluate conditions and factors that increase the effectiveness of the biochar including the addition of alumina nanoparticles.
