Sweet Solution: Turning Agri-Waste to Good Use
In countries where sugar cane is grown, such as Cuba and Brazil, this agricultural waste product has been added to cement for years. Extracting sugar from the cane typically leaves a lot of fiber waste that is burned into ash, discarded and then requires disposal.
Using sugar cane ash also can lower the energy use and carbon footprint of cement production. Heloisa Bordallo, a researcher at the Institute, comments, “You are saving both CO2 emissions and raw materials.” Source: EcoSeed.org
