Physical properties characterization of fuel briquette made from spent bleaching earth

Cooking oil industry in Indonesia produces a massive amount of solid waste, called Spent Bleaching Earth (SBE). Briquetting of this waste can be a good alternative to achieve zero-waste, as well as minimizing energy cost, in this industry. Therefore, the valorization of SBE as briquette was studied using different pressure and maltodextrin dosage. The results show that the physical characteristics of SBE briquette were similar to that of standard value for the wood briquette (Indonesian National Standard or SNI 1-6235-2000).
