Track: Waste Management
Abstract
In this study, the potential to make charcoal briquettes from brewery waste was investigated in a bid to utilize brewery waste and come up with an alternative source of energy. Brewery spent grains were first shredded to reduce the particle size to a range of 2-10 mm and then briquetted at 2 MPa at a 1-minute compaction periods to square biomass briquettes. The briquettes were then carbonized at temperatures varying between 200- 600 °C. The charcoal briquettes formed had calorific values ranging from 25-32 MJ/kg with the optimum calorific value being obtained at 400 °C. The charcoal briquettes produced from brewery waste can be used as an alternative source of energy at the same time managing industrial waste to promote environmental sustainability.
