Tindakan Pengembalian Limbah Pabrik Kelapa Sawit Sebagai Upaya Memaksimalkan Zero Waste.

Abstract

Palm oil is one of the plantation commodities that continues to grow in Indonesia. Palm oil mills process oil palm fruit into Crude Palm Oil (CPO) and also produce 75% of waste (solid and liquid). This waste is an environmental issue and requires serious handling. Along with the times and increasing awareness for environmental conservation, waste management is very important. The purpose of waste treatment in addition to preventing environmental damage is to maximize zero waste. Utilization of waste into useful materials is carried out to reduce negative impacts on the environment and create an environmentally industry. Utilization of waste into useful materials is carried out to reduce negative impacts on the environment and create an environmentally sound industry. Palm oil mill waste is in the form of solid waste and liquid waste. Solid waste in the form of shells, fiber is reused as fuel, while empty fruit bunches are used as compost, raw material for paper and animal feed. Palm oil mill effluent will be processed at the WWTP (Wastewater Treatment Plant) and will then be returned to the land (land application). The returning palm oil mill effluent turned out to have an effect on improving soil quality, adding nutrients, soil diversifying mesofauna and macrofauna, also affecting the ratio of male and female flowers. In addition, liquid waste also has the potential to become biogas.
