The Malang City Environment Agency (DLH) is taking strategic steps to modernize its waste management system to reduce dependence on the Supit Urang Landfill. One of the innovations currently undergoing intensive study is the implementation of steam treatment technology, or steam-based waste processing.
Acting Head of the Malang City DLH, Gamaliel Raymond H. Matondang, explained that this method was chosen for its environmental advantages compared to traditional incineration techniques. By utilizing an evaporation system, this technology is claimed to significantly reduce waste residue. Although its potential effectiveness has been proven in several other regions, the Malang City Government is still conducting in-depth feasibility studies regarding investment aspects and required budget needs.
While reviewing the new technology, the Malang City DLH continues to prioritize upstream waste sorting education. Given the dominance of organic waste, composting programs are being accelerated. Meanwhile, for the inorganic category, the agency has successfully processed low-value plastics into an alternative fuel with quality comparable to premium-grade diesel.
Raymond acknowledged that although the production of this alternative fuel has been successfully tested on four-wheeled vehicles, current facility capacity limitations remain a challenge for mass production. The Malang City Government reiterated its commitment to continuing to seek sustainable solutions to achieve an efficient circular economy without compromising environmental balance.
