Biochar is a carbon-rich residue from the pyrolysis of biomass at high temperatures in an oxygen-depleted system. Biochar enables atmospheric CO2 removal via photosynthesis in biomass which is ultimately converted to biochare while also producing energy. Unlike other biomass fuels, biochar does not cause re-emission of CO2, therefore, biochar as a concrete ingredient can significantly reduce carbon emissions associated with Portland cement. In the short term, low-carbon concrete containing biochar could be utilized for transportation infrastructure including roadways, curbs, sidewalks, and bicycle paths. In the longer term, with increased understanding, concrete containing biochar could be utilized in applications like highways, railways, airports, stormwater, and other critical components. In collaboration with Penn State University, the Lehigh team plans to assess the life cycle assessment of several biochar forms and the resulting environmental impact on these concrete mixtures.
