A Waste Composition Study was conducted at Tapak Pelupusan Sanitari Rimba Mas to assess the characteristics, types, and distribution of solid waste received at the facility. The study involved analysing different categories of waste to gain a better understanding of current waste generation and disposal patterns. The findings provide valuable data to support effective waste management planning, enhance operational efficiency, and identify opportunities for waste reduction and resource recovery. This initiative also contributes towards promoting more sustainable and environmentally responsible waste management practices.
