Waste management of household-scale snack industry based on Reduce, Reuse, Recycle (3R) in Watubonang Ponorogo

The household food industry that produces fish-based snacks in Ponorogo needs good waste management. Therefore, the waste is directly disposed of into the irrigation channel and vacant land. The waste produced by the industry contains highly organic compounds, which results in several problems, such as foul odor and eutrophication due to excess nitrogen and phosphorus. The management of water and solid wastes is a must to prevent environmental pollution, reduce waste circulation, and create better production; one of the methods that can be used is Reduce, Reuse, and Recycle (3R). Primary data were collected by sampling, laboratory analysis, and field research. In contrast, the secondary data were collected through literature studies. Based on the analysis results, reduction is done on liquid waste, compostable, and non-recyclable solid waste. Reuse is done on liquid waste and recyclable solid waste. Recycle is done on compostable and recyclable solid waste. Based on waste management, the treatment units begin with a grease, then an equalization basin, an Anaerobic Baffled Reactor (ABR), and constructed wetland. Solid waste storage for all types uses closed High Density Polyethylene (HDPE) tubs. Composting is carried out on compostable solid waste aerobically in a HDPE plastic tub.
