Pulogadung industrial estate turns source sorting into a working model for Jakarta's business districts

Jakarta's push to sort waste at the source has so far been told mostly through households, neighbourhood associations and kelurahan offices. On 2 October 2026 a different kind of generator stepped into the story. PT Jakarta Industrial Estate Pulogadung (PT JIEP), which manages the Pulogadung Industrial Estate in East Jakarta, set out how it is applying sorting and organic processing across an estate of 433 hectares that hosts more than 400 operating companies.

The announcement is modest in tone and specific in content. It reports a compost tally, names the facility doing the work, and lists the groups the company is training beyond its own fence. For a city that now sends only residue to Bantargebang, that combination of a measured output and an outward-facing programme is exactly what other estates, office districts and commercial zones will want to study.

What PT JIEP announced

According to ANTARA's report of 2 October, PT JIEP is strengthening sorting and processing at the source inside the Pulogadung estate as part of its support for Governor's Instruction (Ingub) No. 5 of 2026 on the Movement for Waste Sorting and Processing from the Source. The company runs a TPS3R facility, the reduce, reuse and recycle site model used across Indonesia, where organic waste from the estate is separated and composted. The resulting compost is used for greening within the estate and for its plant nursery.

President Director Dharma Satriadi framed the work as a natural extension of the company's role. He said the approach fits PT JIEP's position as an estate manager, and that the company is translating sorting and processing principles through area management, education, the provision of facilities and collaboration with government and communities.

"Reducing the waste that ends up in Bantargebang cannot be done by one party alone." Dharma Satriadi, President Director, PT JIEP

Olenka, which carried the company's fuller statement, reports that Dharma linked this to a broad coalition: estate managers, businesses, workers, government, schools and the public, all of whom need to keep sorting and processing consistent from the point where waste is generated.

The numbers behind the compost

The figures PT JIEP released are small in absolute terms and precise in a way that is useful. From 2023 to 2026, manual composting at the estate produced 50,572 kilograms, or about 50.6 tonnes. Machine processing added a further 4,040.8 kilograms, about 4 tonnes. The total recorded compost output is therefore 54,612.8 kilograms, roughly 54.6 tonnes.

Two readings of these numbers matter for practitioners. The first is that most of the output so far has come from manual methods, with mechanised processing a recent and smaller contributor. That is a familiar pattern for TPS3R sites in Indonesia, and it suggests room to grow throughput as machine capacity is used more fully. The second is that the company has kept a cumulative record by method across several years. Many facilities can describe what they do. Fewer can show a ledger. A tally of this kind is the starting point for any later conversation about diversion rates, offtake for compost, or the business case for more equipment.

What the figures do not yet show is the share of the estate's total organic stream that the TPS3R captures, or the volume of inorganic and residual waste leaving the estate. Neither source published those numbers, and Sirkularium does not estimate them here. They would be the natural next disclosure as the programme matures.

Why an industrial estate matters to Jakarta's sorting drive

Ingub No. 5 of 2026 took effect on 10 May 2026 against a backdrop of Jakarta generating 7,500 to 8,000 tonnes of waste a day, according to Good News From Indonesia's summary of the instruction. It sets out four streams. Organics, marked green, go to composting, black soldier fly larvae or biodigesters. Inorganics, marked yellow, go to waste banks and recyclers. Hazardous household items, marked red, go to dedicated B3 collection points. Residue, marked grey, is the only stream intended for final disposal or for RDF and waste-to-energy plants. From 1 August 2026 only residue may be sent to Bantargebang.

Most public discussion of the instruction has focused on homes, which detikNews notes are its main addressees alongside their surrounding environments. Yet the logic of the instruction applies with equal force to large non-household generators, and Jakarta already has a rule for them. Kompas, Medcom and Okezone, reporting on PT JIEP's July plans, all point to Governor Regulation No. 102 of 2021, which requires industrial estates and companies to manage their waste independently before anything is passed on to Bantargebang.

An industrial estate is well placed to make that rule work. It has a single manager, a defined boundary, a known set of tenants and existing service contracts. That gives it the governance tools that a dispersed residential area lacks. When an estate operator sets sorting expectations, provides the bins and runs the processing site, compliance can be designed into everyday operations rather than encouraged one household at a time. Pulogadung, which Okezone describes as Indonesia's oldest industrial estate, is a fitting place to show how that can be done.

Reaching beyond the estate fence

The most interesting part of PT JIEP's programme may be the work it does outside its own operations. ANTARA and Olenka both describe an education track with several strands. The company works with the Jakarta Environment Agency to train PPSU personnel, the city's public infrastructure and facilities crews, in various parts of Jakarta. It provides sorting equipment to schools and to RT and RW neighbourhood units in its ring 1 area, the communities immediately around the estate, together with education on sorting at the source. It trains waste bank communities, runs internal education for its own employees, and works with tenant businesses to encourage waste management that goes further than simply collecting and hauling.

This outward reach builds on earlier activity. Metro TV News reported that PT JIEP had already run organic waste and urban farming education for pupils at SDN 01 Rawaterate inside the estate, and that the company operated two urban farming sites totalling 1.2 hectares at the time. In July 2026 the company also signed a memorandum of understanding and a non-disclosure agreement with PT Morego Green Indonesia to develop a technology-based, integrated waste management system for the estate. Dharma described that signing as a first step in building synergy, while Morego Green chairman Wing Indrasmoro said the partnership aimed at solutions that reduce environmental burden and also create economic value from resources.

Read together, these steps describe a sequence that other estates could follow: start with organics and a simple facility, keep records, extend education to the people who handle waste every day, and then bring in technology partners once the basics are in place. The October update shows the first stages are producing measurable results while the technology track is still being developed.

Sirkularium's view: a template for non-household generators

For government and public institutions, the Pulogadung case offers three practical lessons.

First, large generators can carry part of the source sorting load if they are given clear expectations and recognition. Pergub 102/2021 and Ingub 5/2026 together already provide the legal frame. What helps now is visible examples. The provincial government and the Environment Agency could encourage other estates and business districts to publish the same kind of cumulative tally PT JIEP has released, so that progress can be compared and celebrated.

A compost ledger kept by method and by year is a small thing, but it is the foundation on which diversion targets, offtake agreements and equipment investment can later be built.

Second, the training of PPSU crews and ring 1 communities is a sensible use of an estate's capacity. The people who collect, sweep and transport waste are the ones who decide in practice whether separated streams stay separated. Partnerships that put estate resources behind that frontline workforce deserve support and wider replication across Jakarta's five administrative cities.

Third, the planned technology partnership with PT Morego Green Indonesia is the stage to watch. Once details are available, the useful questions will be which streams it targets, what capacity it adds beyond the current TPS3R, and how its outputs will be measured. A clear baseline, which the compost figures begin to provide, will make that next phase easier to evaluate.

What to watch next: whether PT JIEP publishes data on the share of estate waste now diverted from Bantargebang, how tenant participation develops, and whether the Environment Agency adopts industrial estates as a distinct track within the Ingub 5/2026 rollout. If it does, Pulogadung's early numbers could become the reference point that helps other zones move from compliance to genuine circular practice.
