The Indonesia National Plastic Action Partnership (NPAP) system model estimates that 620,000 tonnes of plastic entered Indonesia’s waters in 2017.18 Most plastics are not collected into a managed waste system after use (4.2 million tonnes, or 61% of plastic waste). This leaves households and small businesses with no other option than to dispose of them in an environmentally harmful way: 78% of uncollected plastic waste is burned by households, often close to homes, 12% of it is discarded into bodies of water and 10% is dumped on land or buried and can then end up in bodies of water through rainwater runoffs. Much larger volumes are burned by households, often close to homes (about 78% of uncollected plastic waste).
Of the plastic waste that is collected, most are handled by local governments (2.1 million tonnes, or 32% of total plastic waste). Nearly all of this waste is combined with other household waste streams and goes directly to landfills or official dumpsites19 without sorting of waste at households or in the collection system. We estimate that government-run sorting centers (TPS3R) process around 1% of waste collected. Approximately 8% of plastic waste that is collected by local governments is brought to uncontrolled official dumpsites from where it can leak into the environment, including into water bodies. As of early 2020, Indonesia does not have commercial-scale incineration or waste-to-energy facilities, but several are planned.
Of the 1 million tonnes of plastic waste that the informal sector collects for recycling, around 700,000 tonnes are transformed into recycled plastic; the remaining 300,000 tonnes are eventually disposed of due to yield losses in the sorting and recycling process, such as after contamination with organic material.
This puts Indonesia’s plastic recycling rate at around 10% of the total 6.8 million tonnes of plastic waste generated (measured as a percentage of plastic waste that is actually recycled into new plastic). Of recycled plastics, around 85% are processed in a way that makes it difficult to recycle the product again. An example of this is PET bottles recycled into textiles or mixed plastics.
