Indonesias Organic Waste Landfill ban

A significant step to comply with the Global Methane Pledge

In a significant and forward-thinking move, the West Java provincial government officially prohibited the disposal of organic waste in the Sarimukti landfill, located in the West Bandung Regency, effective January 1, 2024. This comes as a response to the  August 2023 Sarimukti landfill fires. The policy has the potential to divert 228,855 tons of organic waste per year from Bandung alone — preventing 575,428 tonnes CO2eq of methane emissions per year from the landfill. The West Java Provincial government has targeted a reduction of 754,154 tonnes CO2eq from all the landfills in West Java by 2030. This means that Bandung, the capital of the province, can contribute 75% of the set target.

Apart from reducing methane, this policy has the potential to contribute to environmental justice by significantly reducing river pollution caused by the landfill’s leachate, which is a water source for more than 6,000 people. If implemented in parallel with separate organic waste collection and treatment, cities could save significant costs, particularly on transportation, and it could also contribute to the local economy, creating 6 jobs per tonnes of waste managed, double the current system.

Methane, a greenhouse gas 86 times more potent than carbon dioxide, is an increasingly significant global concern to deliver climate action. According to the UNEP’s Global Methane Assessment, reducing methane is a crucial step to keep global warming under 1´5ºC, the threshold established by the Paris Agreement. Interestingly, the Climate Transparency Report (2022) highlights that Indonesia’s waste sector is the country’s largest methane emitter.

In 2023, Sarimukti landfill, a regional landfill serving four cities in West Java, was projected to surpass its capacity. Landfill fires got out of control – AZWI reported 38 landfill fire occurrences in 2023,  attributing methane from organic waste as its root cause. Responding to this critical situation, the Bandung Zero Waste Forum and grassroots groups, particularly Friends of The Earth Indonesia (WALHI) and Yaksa Pelestari Bumi Berkelanjutan (YPBB) —members of Alliance for Zero Waste Indonesia (AZWI)— initiated intensive advocacy efforts, targeting the ban of organic waste landfilling and incineration, emphasizing how the air pollution was affecting waste pickers and the community around the landfill. By August 2023, provincial and local governments declared a waste emergency status, and soon after, the organic waste ban to landfill was sealed.

Incinerator Threat Looms

However, while this policy is a critical milestone for the Metro Bandung area, the provincial government is risking this achievement with a Waste-to-Energy incinerator project proposal in Legok Nangka, a newly built regional landfill to replace Sarimukti. In opposition, WALHI has continuously warned the government about the hidden risks of incineration, emphasizing the risk of methane-to-carbon swapping, the obstacle it will pose to cities to achieve its climate and waste reduction targets, and its adverse impacts to local communities. Accordingly, YPBB and Bandung Zero Waste Forum advocate for coherent policies through alternative policy scenarios that do not rely on incineration. 

Furthermore, the organic waste ban to landfill should be implemented carefully. The government must not allow pitfalls as experienced by the European “zero waste to landfill” policy, which has resulted in an excess of incineration capacity in this region. The policy should be more ambitious by including a mandatory source separation, separate collection, and treatment of organic waste, and a ban on landfilling ‘untreated organic waste’.

Zero Waste is Already Happening

It is critical that the organic waste ban to landfill policy drives and scales up the existing zero waste models. Nine zero-waste city models throughout Indonesia (Bandung City, Bandung Regency, Cimahi, Sumedang, Purwakarta, Karawang, Gresik, Denpasar and Gianyar) organized by AZWI cover a population of more than 478,000 people with an average of 40% waste segregation compliance rate, up to an 88% in the best cases, which is by far the highest in the country. In total, these zero waste models have the potential to reduce organic waste sent to landfill by 6,500 tons per year. In a recent report, YPBB and GAIA found that a city-scale zero waste implementation in Bandung is four times more climate-effective than incineration. The success of these zero waste initiatives has relied on two strategic pillars:

1. implementation of waste prevention measures, source separation and separate collection of various waste streams, including organic waste; and

2. strong community engagement with a clear priority for inclusion of informal waste collectors. Ultimately, local stakeholders have played a pivotal role in implementing the zero waste models that started with minimal government support.

In conclusion,  the level of ambition required in achieving Indonesia’s climate commitments, and the political momentum in West Java should be harnessed to drive systemic change. This can happen now thanks to decades of collective and dedicated work of local groups like YPBB, Bandung Zero Waste Forum, WALHI, and AZWI. To make the most of this, governments and financial institutions must create the right flow of resources and capacity — aligned with Environmental Justice principles — making the inclusion of local organizations a clear priority for a lasting impact.
