Workers cleans up waste on the ocean side before the upcoming G20 in Bali - 

Indonesia is preparing to welcome dozens of heads of state at the G20 Summit in Bali on November 15-16. All supporting activities are prepared, including waste management. As the location of the peak of international events, of course, this issue becomes a priority.

In order to prepare for the event, the Mayor of Bali, IGN Jaya Negara, is mobilizing resources to clean up the garbage in 23 3R TPS in Denpasar City. This step is taken so that there are no piles of garbage in Denpasar, which will be passed by the heads of state at the G20 Summit.

"We cleaned it before the G20, we emptied it, in collaboration with the Gianyar Regency Government, it will be exiled to Temesi. So that in the G20 area there is no mobility of waste there. Empty. Neat,” he explained when interviewed by telephone by the G20 media team, Saturday (5/11/2022).

The Mayor of Denpasar Jaya is also committed to ensuring the cleanliness and comfort of the G20 event.

Currently, there are three TPSTs in Bali, namely Tahura Ngurah Rai, TPST Kesiman Kertalangu, and TPST Padang Sambian Kaja. All three are in the process of installing waste processing equipment. Tahura Ngurah Rai and Kesiman Kertalangu will start operating before the peak of the G20 Presidency next November.

"The physical progress will be completed before the G20, and the machine can only be operational in Tahura 2 and in Kertalangu, but the process is not yet complete. The capacity is only 20 tons during the trial," explained Jaya Negara.

The three new TPSTs on the Island of the Gods were built because the Suwung landfill has exceeded capacity.

The construction of the TPST is a benefit that Bali receives from the G20 Summit. Because after the summit, Bali will maximize its use as a waste processing facility. "And he (the manager) agreed that at the end of November it was only 100 percent completed," he said.

According to a release received by Voice of Indonesia on Saturday, waste management has become a serious concern for the government of President Joko Widodo. During the G20 implementation, Minister of Home Affairs Tito Karnavian said that four districts/cities in Bali, namely Denpasar, Badung, Gianyar, and Tabanan, were the main focus areas for waste management.

"The place which is the location of the G20 and its surroundings as well as the four areas must have good waste management so that we can talk. Even if necessary they (the G20 delegation) come to see," said Tito, while visiting the Kertalangu TPST, last September.

Moreover, Tito reminded that at the G20 meeting there would be discussions on climate change. Therefore, waste management is an important part.

Indonesia makes Bali as one of the pilot provinces that implement net zero emission in 2045. Meanwhile, one of the contributors to greenhouse gas emissions is waste. For this, better waste management is needed.

Assistant Deputy for Waste and Waste Management at the Coordinating Ministry for Maritime Affairs, Rofi Alhanif, said that waste that is not managed properly will release methane that pollutes ozone.

Another interesting thing about the three new TPSTs is the application of RDF (refused derived fuel) technology. RDF technology is a technology in processing waste into biomass which can then be used as a new and renewable energy source (EBT). This waste-processed biomass is a coal co-firing in the cement industry and steam power plants (PLTU). This is in line with the G20 agenda in the field of energy transition.

This refused derived fuel (RDF) product can be used as a substitute for LPG gas for pyrolysis reactors in accordance with the concept of a green and zero waste waste treatment model.

With this waste management technology, it is hoped that it can reduce the waste problem and turn it into a product of economic value so that it can improve the welfare of the community. In addition, the location of waste processing has the potential to become a place for training and tourism.

In Indonesia, the development of the first RDF TPST is in Tritih Lor Village, Jeruklegi District, Cilacap, Central Java. The construction of the RDF facility in an area of ​​3 hectares has been carried out since 2017.

The construction of the RDF TPST is arguably a new milestone in waste management in Indonesia as well as a step towards the energy transition. From Cilacap the government then developed the RDF TPST infrastructure in Kongok Gardens, Lombok, West Nusa Tenggara (NTB)//VOI
