This was revealed through CLOCC’s data collection, part of its waste management planning process. The purpose of the data collection was to explore how much waste is generated, how it is managed and how much leaks into the environment in the regency of Tabanan
The baseline study was executed in collaboration with partner Indonesia Solid Waste Association (InSWA) and Udayana University, and local authorities and waste management stakeholders. It is the first step in creating an integrated and sustainable waste management for the Regency of Tabanan and the villages.
Waste management planning needs reliable data on waste generation and composition. The data quality will affect waste management planning from the design process - flow of collection and transportation, to the quantity and specifications of waste processing facilities.
202 tons of waste daily is not properly managed
The survey found that the total potential waste generated in Tabanan is 422 tons per day. Of this, 41% derives from domestic sources and 59% from non-domestic. The waste composition is 62% organic, 19% plastic, 7% residue and 12% other wastes.
Of this, 120 tons per day (28%) is handled by the formal sector (waste banks, waste facilities, landfill). 100 tons per day (24%) is handled by the informal sector (scavengers, collectors, recycling industry). 2 % of the managed waste ends up in the agriculture sector, 25% in the recycling industry, and 25% in landfill.
202 tons per day (48%) of the waste is not handled properly and leaks into the environment through illegal dumping, burned or dumped into water bodies.
The research shows that plastic from domestic sources is dominated by LDPE and film plastic (46% and 34%), which is of low economic value.
It was also found that only 100.54 tons of waste per day (24%) can be managed in Tabanan’s recovery facilities, based on current capacity.
The methodology used was the UN Habitat’s Waste Wise Cities Tools and the Indonesian national standard SNI Method 19- 2964-1994.
The data collection took place over 8 days. The sampling locations were categorized into domestic and non-domestic. Households were categorized into low, middle and high income households, with a total sample of 120 households. Non-households included shops, offices, schools, health facilities, with a total sample of 98. Sampling is also carried out at 10 MRFs (Material Recovery Facilities) and at the Madung landfill, including informal sector activities.
Conclusions and recommendations
Village government needs support to ensure they have the capacity to plan for waste management activities to manage the large amounts of waste. This also includes efforts to nudge people’s behavior towards reducing and segregating waste at the source.
Providing technical guidance to the village government to manage TPS3R (village level recovery facility) is key. It is clear that the role of the formal waste management sector, including waste banks and TPS3Rs must be strengthened in order to reduce waste accumulating in landfill or leaking into the environment.
The recycling sector in Bali is limited, especially for materials such as paper, metal and glass. Such materials are often distributed to Regencies outside Bali, which causes high operational costs and unsustainable business practices. Because of the costs it is also a common practice for waste collectors to dispose of the residues directly into the environment rather than the landfill.
The waste composition analysis shows that the most common plastic from domestic activities is of low value. Serious efforts are needed to boost the collection of such plastic. It is important to reduce the use of low value plastic in communities to reduce residual waste ending up in landfills.
The next steps for the CLOCC programme in Tabanan is to use the data as the foundation for planning a new waste management system for Tabanan Regency. Read the full report here.
