Philippines Land Gets Dirty With Trash

In the first two months of 2026 alone, two major garbage landslides in the Philippines killed at least 38 people — one at a landfill in Cebu City and another in Rodriguez, Rizal. These are not isolated accidents but recurring failures of a waste management system under immense strain. When a mountain of trash collapses, it reveals deeper problems: landfills built on unstable ground, operating beyond capacity, and often in violation of the very laws meant to prevent such disasters.

These figures point to a system where the margin for error has all but disappeared. The Binaliw landfill in Cebu, for instance, handles nearly all of Cebu City’s trash — a concentration of risk that makes a single failure catastrophic. When a facility is that central to a city’s waste stream, any operational lapse can trigger a crisis. The Rodriguez landslide, meanwhile, occurred at a privately owned dump operated by International Solid Waste Integrated Management Specialist, Inc. (ISWIMS), prompting the provincial governor to request a probe from the Department of Environment and Natural Resources. The pattern is consistent: landfills fail not because of one mistake, but because of accumulated violations, poor design, and regulatory gaps that go unaddressed for years. For a deeper look at how these issues have unfolded across multiple sites, see our earlier coverage of trash troubles plaguing Filipino landfills.

What drives a landfill to collapse

These causes come from a global review of 62 landfill failures across 22 countries by Zhang et al. (2020). The study provides a useful framework for understanding what went wrong in the Philippines, but local conditions add another layer. Many Philippine landfills are built on or near watersheds, residential areas, or protected zones — locations that were never suitable for waste disposal in the first place. The Binaliw landfill, for example, sits on the Butuanon watershed, a fact confirmed by a former city legal officer. That alone should have disqualified the site, yet it operated for years.

The consequences of poor leachate management are not theoretical. In Binaliw, residents reported that garbage liquid flowed into their neighbourhood whenever it rained. More than 600 residents signed a petition demanding the landfill’s closure, citing health concerns and an unbearable stench. The Environmental Management Bureau (EMB) later found violations related to garbage hauling and monitoring reports, but the landfill continued operating. This gap between detection and enforcement is a recurring theme across the country.

How landfills became a crisis waiting to happen

The roots of the current crisis stretch back decades. When the Inayawan Sanitary Landfill in Cebu City — the city’s main disposal site since 1998 — was shut down for rehabilitation in 2017, it was long overdue. The landfill was only built to last seven years. Its closure forced the city to scramble for alternatives, eventually turning to a private landfill in Barangay Binaliw that had already faced controversy before it even opened.

The timeline of the Binaliw landfill illustrates how regulatory failures compound over time. In 2017, the operator’s parent company, ARN Builders Incorporated, was accused of conducting illegal quarrying on the site without property owners’ consent — quarrying that a city councilor claimed was done in preparation for the landfill. At that point, the landfill did not yet have an Environmental Compliance Certificate (ECC). The city council initially disapproved the project in April 2017 over a lack of transparency, only to approve it in August 2018. That same year, ARN won a P65-million contract with the Cebu City government for garbage collection and disposal, signed by then-mayor Tomas Osmeña.

The landfill’s problems did not end with its approval. In 2019, the EMB found violations related to the ECC, though it did not elaborate. ARN claimed it had addressed the issues, calling them administrative rather than environmental. The city cancelled the contract in July 2019, but by then 40 haulers were already using the facility. When Prime Integrated Waste Solutions Incorporated (PWS) — a subsidiary of billionaire Enrique K. Razon Jr.’s Prime Infrastructure Capital Incorporated — took over in January 2023, the problems continued. An inspection in August 2024 found that PWS was allowing waste to be disposed of in an open and untreated manner, effectively operating an open dumpsite in violation of Republic Act 9003, the Ecological Solid Waste Management Act. No sanctions were imposed.

The Binaliw case is not unique. In Calamba City, the SB Hain landfill received a cease and desist order from the mayor in November 2023, expecting the facility to correct its violations. The DENR had served the same order in July 2020 due to “numerous violations” of its ECC terms. The landfill sits on a 6.6-hectare site that, by regulation, should not be within 250 metres of residential areas — yet it operates in a populated area. The Kay-anlog landfill in the same region receives a thousand tons of refuse daily, equivalent to over 333 garbage trucks, with waste coming from 16 towns and cities across Laguna, Cavite, and Batangas. The sheer volume these facilities handle, combined with weak enforcement, creates conditions where failure is not a matter of if, but when.

What gets missed in the conversation about landfill safety

Most discussions about landfill failures focus on the immediate cause — a heavy rain, a slope failure, a gas explosion. But the underlying factors are more structural and harder to fix. One of the most overlooked is the role of pollution and poverty in shaping where landfills are sited and who bears the risk. Landfills are disproportionately located in low-income communities where residents have less political power to resist them. The Lupang Pangako disaster in Quezon City, which killed at least 200 people nearly 25 years ago, was a tragedy that unfolded in a poor community living next to an unregulated dump. The same dynamics are at play today.

Another factor that gets less attention is the classification system for landfills. The SB Hain landfill started as a Category 1 site in July 2018 before becoming Category 4 a year later. Category 4 landfills are supposed to meet higher standards for environmental protection, but the upgrade did not prevent the facility from receiving cease and desist orders. The classification system creates an appearance of oversight without necessarily improving outcomes on the ground.

There is also the question of what happens when a landfill reaches capacity. The EMB data shows that four of the 18 biggest landfills in the Philippines have already maxed out, and all four are planning to expand. Expanding a landfill that is already full is a temporary fix that postpones the harder question of where the waste will go in the long term. Meanwhile, 23 new facilities were set up from 2021 to 2022, and 38 others are under construction. The country is building its way out of a waste crisis, but new landfills bring new risks — especially if they repeat the design and siting mistakes of the past.

The role of inadequate drainage and stormwater management

The Commission on Audit found that the Binaliw landfill had inadequate drainage and stormwater management, along with infestations of flies and rats, foul odour, and a potential leak in its treatment plant. These findings are significant because poor drainage directly contributes to leachate buildup, which is the leading cause of landfill slope failures. When rainwater cannot be channelled away from the waste pile, it percolates through the garbage, increasing the liquid load and reducing stability. The audit findings suggest that the landfill was not just operating poorly — it was operating in a way that made a collapse more likely.

The gap between detection and enforcement

Across multiple cases — Binaliw, SB Hain, the AESC landfill in Consolacion — violations were detected by regulators but rarely resulted in meaningful penalties. The AESC landfill was shut down in May 2019 after a landslide killed a garbage truck driver, but only after years of violations. The Binaliw landfill was found to be operating as an open dumpsite in 2024, yet no sanctions were imposed. The city government instead vowed to help the operator correct its deficiencies. This pattern suggests that enforcement is reactive rather than preventive, and that the consequences of non-compliance are often too weak to change behaviour.

What can be done about landfill safety

Addressing the landfill crisis requires action at multiple levels — from individual waste reduction to systemic regulatory reform. The following sections outline practical steps that different stakeholders can take, based on the evidence from recent failures.

Strengthening regulatory enforcement

The most immediate need is for regulators to impose real consequences for violations. The DENR and EMB have the authority to issue cease and desist orders, revoke ECCs, and impose fines, but these tools are used inconsistently. When the Binaliw landfill was found to be operating as an open dumpsite in 2024, no sanctions followed. A more effective approach would involve automatic penalties for specific violations — for example, a mandatory fine for any landfill found to be accepting waste beyond its permitted capacity, or for failing to submit required monitoring reports. The process for reporting violations also needs to be clearer. Residents and local officials should have a direct channel to the EMB that triggers an inspection within a set timeframe, rather than relying on petitions and media pressure.

Improving landfill design and monitoring

The global data on landfill failures points to specific design improvements that can reduce risk. High leachate levels are the leading cause of failure, so better leachate collection and drainage systems should be a priority. This means installing and maintaining proper liners, leachate pumps, and stormwater diversion channels. Regular monitoring of leachate levels, gas pressure, and slope movement should be mandatory and the data made publicly available. The EMB already requires monitoring reports, but the Binaliw case shows that these requirements are not always met. A simple fix would be to require real-time monitoring data to be submitted electronically, with automatic alerts when levels exceed safe thresholds.

Reducing waste volume at the source

No amount of landfill improvement will solve the problem if the volume of waste continues to grow. The Kay-anlog landfill receives a thousand tons of refuse daily, and the Binaliw landfill handles nearly all of Cebu City’s waste. Reducing this volume requires better waste segregation, recycling, and composting at the household and municipal level. Republic Act 9003 already mandates segregation at source, but enforcement is weak. Local governments can strengthen compliance by providing separate collection schedules for biodegradable and non-biodegradable waste, and by establishing materials recovery facilities (MRFs) that actually process what they receive. PWS inaugurated an MRF in Pampanga with a capacity of 5,000 tons per day in June 2024, which shows that large-scale processing is possible — but it needs to be paired with consistent collection and segregation upstream.

Planning for landfill transitions

Four of the 18 biggest landfills have already maxed out their capacity, and all are planning to expand. Expansion is a short-term solution. A more sustainable approach involves planning for the eventual closure of each landfill years in advance, identifying alternative disposal sites or technologies, and budgeting for post-closure maintenance. The Inayawan landfill in Cebu was only built to last seven years but operated for nearly 20, which meant its closure was chaotic and reactive. A structured transition plan would include a timeline for reducing waste intake, a schedule for capping and sealing the site, and a fund for long-term monitoring of leachate and gas emissions.

Closing thoughts

The deaths at Binaliw and Rodriguez in early 2026 are not anomalies — they are the predictable outcome of a system that prioritises disposal over safety, expansion over planning, and convenience over enforcement. The evidence from past failures, regulatory audits, and global research is clear about what needs to change: better leachate management, consistent enforcement, reduced waste volume, and honest planning for landfill transitions. These are not easy fixes, but they are known ones. The question is whether the country will act on them before the next collapse.
