West Nusa Tenggara ties waste management to village economics across 28 locations

A project that starts with the business model

On 1 September 2026, the West Nusa Tenggara regional research and innovation agency set out the approach behind PELITA, the integrated waste management project running in the province.

PELITA is a cooperation between Indonesia and the United Kingdom, delivered through the Low Carbon Development Indonesia Innovation and Technology Fund. It targets 28 villages across NTB, with construction running from September 2026 to April 2027. Among the locations are Gili Trawangan, Gili Air and Pulau Moyo.

The province generates around 2,500 tonnes of waste a day.

I Gede Putu Aryadi, who heads the provincial research and innovation agency, framed the design around a failure mode rather than around an ambition.

Waste management programmes must not stop at building facilities. They have to ensure there is institutional capacity, human resources, a business model and management mechanisms able to sustain the programme.

That sentence describes the single most common way donor funded waste infrastructure fails in Indonesia. A facility is built, handed over, and operated for as long as the project team remains. When the funding cycle ends, there is no entity with a legal mandate to run it, no revenue covering its costs, and no trained staff. The building remains and the service stops.

Designing against that outcome from the start, rather than treating sustainability as a closing workshop, is what distinguishes this programme on paper. Whether it distinguishes it in practice is a question for 2028.

The technical shape of it

The programme concentrates on the organic fraction, converting it into biogas fuel and organic fertiliser.

Yayasan Rumah Energi is conducting a feasibility study for biodigester development within PELITA, covering 33 units of 4 cubic metres each, distributed across Lombok and Sumbawa.

Four cubic metres is a domestic or small community scale unit rather than an industrial one. That sizing is consistent with the village level design: a unit that a household group or a neighbourhood can feed, operate and maintain, producing gas usable for cooking and a digestate that has value as fertiliser.

The choice matters for the economics. A large centralised digester requires collection logistics, a technical operator and a gas offtake arrangement. A distributed network of small units requires none of those, and its output is consumed where it is produced. The trade off is that small units are harder to monitor and easier to abandon quietly, which brings the discussion back to Aryadi's point about management mechanisms.

Anna Amaliya of Bappenas, coordinating low carbon development, placed the work in the national frame, noting that climate action has to accompany economic growth and improvements in welfare rather than compete with them.

The focus on the organic fraction is also technically correct for village scale. Organic material is the largest share of household waste generation in Indonesia, the share that most quickly produces odour and leachate if left, and the share of least interest to collectors. No market waits for food scraps the way it waits for plastic bottles. That makes the organic fraction the part most likely to remain in the village absent an intervention, and simultaneously the part easiest to process on site.

Why the islands are the interesting test

Gili Trawangan and Gili Air are small tourist islands. They present a version of the waste problem that is unusually stark and unusually instructive.

An island has no landfill option worth the name. Every tonne that is not processed locally has to be shipped to the mainland, at a cost per tonne far above what a mainland district pays. Waste generation is also seasonal and driven by visitors rather than residents, so per capita planning figures based on population understate the load considerably.

Those constraints make islands the places where circular approaches stop being preferable and become necessary. Processing organic waste on the island removes the heaviest and wettest fraction from the shipping bill immediately, because organic material is mostly water and is the most expensive thing to move.

It also makes the islands a useful demonstration site. A model that works under island economics, where the alternative is expensive shipping, will generally work on the mainland where the alternative is a landfill fee. The reverse is not true.

The inclusion element

The programme has an explicit distributional design, targeting economic benefit at women, young people and persons with disabilities.

This is more than a framing choice. Waste recovery work at village level is already substantially performed by women, often informally and unpaid, as an extension of household management. A programme that formalises those roles and attaches income to them converts existing unrecognised labour into recognised employment. That is a different proposition from creating new jobs, and generally an easier one to sustain, because the skills and the routines already exist.

Aryadi also made a point about the ecosystem, arguing that government, community, universities, business and development partners have to work within one system so that separate initiatives do not stop partway. In a province where multiple donors, ministries and NGOs run waste programmes simultaneously, that coordination question is not rhetorical.

Sirkularium's view for government and public institutions

Three observations.

First, on writing the operating entity into the design. The most valuable feature of PELITA's stated approach is that institutional capacity, business model and management mechanism are named as deliverables alongside the physical infrastructure. Districts and provinces receiving donor funded waste infrastructure should require the same, and should insist that the operating entity is legally constituted and has a revenue line before handover rather than after. We would encourage NTB to publish what that entity looks like in each of the 28 villages.

Second, on sizing technology to the operator. The choice of 4 cubic metre biodigesters over a centralised plant reflects who will run them. That principle generalises. Local governments should specify equipment against the capability of the intended operator, because a technically superior unit that nobody in the village can maintain delivers less than a simpler one that someone can.

Third, on islands as proving grounds. Provinces with small island territories should treat them as priority sites for circular infrastructure rather than as difficult peripheral cases. The economics are more favourable there than anywhere on the mainland, because the avoided cost of shipping waste out is high and immediate. Results from Gili Trawangan and Gili Air will carry an evidence value well beyond NTB.

What to watch next: completion of construction across the 28 villages by April 2027, the outcome of the biodigester feasibility study and how many of the 33 units proceed, the legal form and revenue model of the village operating entities, and whether waste shipped off the Gili islands to the mainland falls measurably.

NTB has named the failure mode it is designing against. Sirkularium will continue following whether the design holds.
