Abstract: Waste banks are well-known community-initiated activities in Indonesia for collecting inorganic waste in neighbourhood areas, in an aim to reduce the volume of waste which goes to the landfill. The collected waste is then sold to industries which resell or reprocess the waste. It has been understood that the sustainability of waste banks depends a lot on the selling price of the waste. Especially for plastic waste, a shredded plastic waste could increase the selling price by almost two times. In this research, design and development of a low-cost shredder for plastic waste is carried out. The shredder with a capacity of +/-30 kg h–1 is installed and operated to aid a neighbourhood-level waste bank in Depok. The main shredding component consists of three rotating blades and two fixed blades. With the aid of a screen, the shredder is expected to shred plastic wastes to small pieces of 15 mm in dimension. A 6.5 hp gasoline engine with a transmission pulley are used as the power source. After the development, the performance is evaluated.
