Two TPSTs in Denpasar Target to Process 500 Tons of Waste per Day
Environment Minister Hanif Faisol Nurofiq visited the Integrated Waste Processing Facility (TPST) Tahura Ngurah Rai in Benoa, Denpasar Selatan, on Thursday, 5 March 2026, accompanied by Bali Governor Wayan Koster and Denpasar Mayor I Gusti Ngurah Jaya Negara. The Tahura Ngurah Rai TPST has three new machines expected to process 300 tons of waste. The group coordinated with the facility operator on waste processing. Two of the new machines are at Tahura Ngurah Rai 1 and one at Tahura Ngurah Rai 2. Added to two new machines at TPST Kesiman Kertalangu, it is estimated that 500 tons of waste in Denpasar can be treated.
General Manager of PT Waste to Wealth (the waste processing technology provider), Aditya Sigit, said the three machines are expected to contribute to the Denpasar City Government’s waste management. He noted that two similar machines are at TPST Kesiman Kertalangu. On average, Denpasar produces around 1,200 tons of waste per day. Therefore, the five machines are expected to relieve Denpasar’s waste processing burden.
‘So in Denpasar City, there will be procurement of machines with a capacity of 300 tons per day at Tahura, and 200 tons per day at Kertalangu. So total about 500 tons,’ Aditya said.
Since 2022, he continued, Tahura Ngurah Rai TPST has performed waste picking (sorting). This TPST is also one of the waste disposal sites in Denpasar when the Suwung landfill is fully closed.
Waste processing machines at Tahura Ngurah Rai and Kertalangu will be processed into waste products such as RDF and carbon. ‘They will go into PLTU (coal-fired power plant) and cement factories; these products result from the processing,’ he added.
Aditya said the processed materials will become supplementary fuels to coal. According to him, the TPST machines have advantages. Besides being able to process at least 100 tons per day, the waste products also yield valuable products.
‘Waste is sorted, then turned into something more valuable. RDF and carbon are bought at around Rp 600 thousand per ton. So there is value that can be obtained from waste production,’ he added.
Aditya is confident that waste processing at Tahura Ngurah Rai TPST will be effective. If successful, he believes Suwung landfill need not be closed.
Aditya hopes waste management in Denpasar can be as effective and modern as Banyumas, Central Java.
‘TYes, gradually, not impossible to achieve zero waste. Like in Banyumas, waste processing is good, the landfill is no longer in use because they have processed waste well,’ he concluded.
TPST Kesiman Kertalangu has Two Machines
Foreman or operator of TPST Kesiman Kertalangu, I Gusti Ngurah Giri Putra, revealed there are two new machines provided by Denpasar City Government and two old machines expected to address the waste problem.
‘There are two additions provided here. Usually for the older machines, waste processing can reach up to 15 tons per day,’ Ngurah Giri Putra said on Thursday (5 March 2026).
He further stated that with the new machines, the waste in East Denpasar, the border of South and North Denpasar can be optimally processed at TPST Kesiman Kertalangu.
TPST Kesiman Kertalangu currently employs 50 workers. The number will increase with the new machines. ‘Currently there are 50 employees, 10 from DLHK and 40 from the private sector. It is possible the number will increase,’ he added.
‘We will support the best possible measures so that the waste problem in Denpasar can be resolved properly,’ he concluded.
