Seven deaths in landfill trash landslides trigger criminal probe into waste mismanagement.
Former Jakarta environment chief Asep Kuswanto has been named a suspect over alleged mismanagement at Bantargebang Landfill, where a series of trash landslides killed seven people between late 2025 and March 2026.
Suspect Named After Deadly Trash Landslides
Former Head of the Jakarta Provincial Environmental Agency Asep Kuswanto was officially named a suspect in the Bantargebang Landfill case on April 21, 2026. Environment Minister Hanif Faisol Nurofiq said the move is part of a law enforcement process into alleged waste mismanagement that failed to meet norms, standards, procedures and criteria, and was aggravated by multiple fatalities and serious injuries. A series of trash landslides at Bantargebang from November to December 2025 and again in March 2026 killed seven people, highlighting long standing concerns over landfill safety and operating practices.
Ministry Cites Regulatory Breaches At Bantargebang
Hanif said the landslide incidents demonstrate that Bantargebang’s management was not in line with existing regulations. He noted that investigators are now pursuing accountability for those responsible for landfill operations. Deputy for Environmental Law Enforcement at the Environment Ministry, Rizal Irawan, explained that authorities had intervened well before the suspect designation. On December 31, 2024, the ministry imposed administrative sanctions on Bantargebang’s management after compliance checks. A first follow up inspection on April 12, 2025, still found non compliance with required standards.
Warnings Issued Before Fatal Collapses
Following the failed April 2025 inspection, the Environment Ministry issued a formal warning letter on April 22, 2025 and granted time for corrective action. However, during another surveillance visit on May 9, 2025, officials concluded that the landfill still did not meet the mandated requirements. Despite these warnings, several trash landslides occurred later that year and into early 2026, culminating in deadly collapses that claimed seven lives. The sequence of sanctions, warnings and subsequent failures will form a key part of the criminal case.
Joint Investigation Builds Criminal Case
Between March and April 2026, the Indonesian National Police and the ministry’s environmental law enforcement teams questioned numerous witnesses, including officials from related agencies and independent experts, to strengthen the case. Rizal said the combined evidence was presented in a case development conference that concluded with Asep’s naming as a suspect on April 21, 2026. Investigators are examining whether systemic negligence, inadequate maintenance or ignored risk assessments contributed to the instability of trash heaps and the eventual landslides at the massive landfill serving Greater Jakarta.
Legal Process Continues, More Suspects Possible
Although Asep has been designated a suspect, Rizal confirmed that he has not been arrested at this stage. The legal process will proceed with further questioning and evidence gathering, including probing the possible involvement of other parties in the landfill’s management chain. Authorities say they aim to establish clear accountability and send a message that failures in managing critical waste infrastructure, especially when they lead to deaths, can result in criminal liability. For Indonesians and Singaporeans, the case underscores the risks of overloaded landfills and the need for stronger environmental governance in fast growing urban regions.
The suspect designation of former Jakarta environment chief Asep Kuswanto in the Bantargebang trash landslide case marks a rare move to criminally pursue senior officials over waste management failures that cost lives. For Indonesians, it highlights pressure on authorities to enforce safety standards at critical facilities, while for Singaporeans and other regional observers it illustrates how lapses in landfill and waste oversight can quickly turn into lethal disasters, strengthening the argument for more resilient urban waste systems across Southeast Asia.
