Cleaner Production Opportunity at Palm Oil Plant to Minimize the Wastewater Effluent and Solid Waste Generation

PT MNA is a palm oil industry that has a processing capacity of 60 tons of FFB/hour with its main products of palm oil (CPO) and Kernel. The palm oil industry, in addition to producing its main product in the form of CPO, also produces solid waste, wastewater and gas emission. The purpose of this study is to identify the flow of materials, products, and non-products in the palm oil processing industry. It also aims to assess the alternatives of waste handling process, identify cleaner production opportunities that can be applied to the palm oil industry The methods used include literature studies, observations, laboratory analysis. PT MNA has treated the waste generation by reusing the solid waste formed as boiler fuel (solid waste) and land application of processed wastewater). There are still problems of waste and loss. Boiler ash is solid waste came from the combustion of fiber or pulp and palm shells in the boiler. It has a rough texture in the form of crust. The strategy for implementing cleaner production at PT MNA, has been considered technically, economically, and environmentally. By modifying the process of adding a condensate and oil water reservoir pool, could produce a B/C value = 2.5 and PBP = 0.50 years. By implementing good housekeeping could reduce dirt on the fruit with GMP (good manufacturing practice) training, having a B/C value = 1.61 and PBP = 1.63 years. By using solid boiler ash waste as a material to minimize the use of Calcium Carbonate (CaCo3) in the clay bath system
