A pile of uncollected garbage has accumulated in front of the Department of Environment and Natural Resources (DENR) XI office in Lanang, marking a growing confrontation between Davao City officials and environmental regulators. The buildup follows a decision by the DENR to suspend operations at the city’s sanitary landfill in Barangay Carmen.
A Crisis of Sanitation and Safety
The suspension was triggered by a trash-slide that occurred at the landfill on May 20, 2026, around 1:10 PM. The incident affected an estimated 3.72 hectares, blocked access roads, damaged nearby houses, and resulted in two fatalities, two injuries, and one individual who remains missing as retrieval operations continue.
Mayor Sebastian “Baste” Duterte has criticized the suspension, attributing the city’s uncollected waste to the “bureaucratic inaptitude of DENR.” He noted that while approximately 180 families have been evacuated from high-risk areas to address the threat to human life, the continued halt of essential services poses a significant public health and sanitation risk.
“We have identified additional collection points, including one in front of the DENR XI office, so they can personally appreciate the volume of garbage that accumulates when an essential public service is halted indefinitely,” Mayor Duterte stated.
In response to the waste being left at their compound, the DENR has warned that it will pursue legal cases against involved individuals and vehicles, citing Section 48 of Republic Act 9003, also known as the Ecological Solid Waste Management Act of 2000.
Regulatory Requirements and Future Outlook
The DENR maintains that the suspension, issued on May 21, will only be lifted once necessary safety and engineering interventions are completed. DENR Davao Regional Director Atty. Ma. Mercedes V. Dumagan stated that the agency is working to ensure that measures are in place to protect workers and nearby communities.

To manage the current crisis, the DENR has proposed several alternatives, including coordinating temporary disposal with neighboring local government units like Sta. Cruz and Panabo City, as well as fast-tracking a new sanitary landfill facility currently under development.
The situation could reach a resolution if the DENR verifies the engineering interventions proposed by the city, which the city has committed to completing by June 9. Alternatively, the city may have to wait until the new landfill facility becomes operational, which is expected by June 16, 2026.
