Rayan Mourad from the American University of Beirut (AUB, Lebanon) studied the replacement of sand by biochar in concrete production. Biochar is a carbonic by-product of waste pyrolysis, a form of recycling.
The project shows new forms of building with concrete as well as opportunities for environmental improvement and economic development. Using biochar in concrete is a way to optimize waste recycling in Lebanon; it can create new job markets and applications. The project also helps reduce the extraction, transport, and consumption of sand.
