Medical Waste Messes in Philippines Pollute Waterways

Hazardous healthcare waste in the Philippines has increased by 20.19 percent over the last five years, with hospitals now generating between 1.13 and 1.31 kg of waste per bed per day. That figure might sound abstract until you consider what it contains: syringes, soiled bandages, pathological waste, and plastics laced with chemicals that, when mismanaged, can leach into groundwater or release toxic fumes when burned. The problem is not just about volume — it is about what happens after the waste leaves the hospital room.

These numbers come from a national push to understand the scale of the issue. The Philippine Healthcare and Mercury Wastes Management Project (HCW Project), a five-year initiative launched in December 2023, is the first coordinated effort to track and treat healthcare waste across multiple regions. Partner hospitals like the Eastern Visayas Medical Center (EVMC) and Quirino Memorial Medical Center (QMMC) have started reporting their waste streams in detail — and the picture is sobering. At QMMC alone, hazardous waste totaled 496,505 kg in 2023, alongside nearly 325,000 kg of general waste. Much of that ends up in waterways, either through direct dumping or via runoff from poorly managed disposal sites. For a deeper look at how pollution more broadly affects Filipino communities, you can read about pollution’s socioeconomic effects on communities.

What Makes Healthcare Waste Different from Ordinary Trash

The distinction matters because ordinary municipal waste systems are not designed to handle these materials. The World Health Organization estimates that 85 percent of healthcare waste is general and non-hazardous, but the remaining 15 percent — the infectious, toxic, and sharps waste — requires special treatment. In the Philippines, the capacity for that treatment is limited. Local government units often lack the facilities to handle even general waste, let alone hazardous materials. Treatment, storage, and disposal (TSD) facilities for hazardous waste are scarce, and delays in collection are common. The result is that hazardous waste sometimes ends up in the same landfills or waterways as household trash.

Where the System Breaks Down: Storage, Segregation, and Awareness

During the project’s inception phase, a critical gap emerged: awareness about proper waste segregation among hospital clients — patients, visitors, and even some staff — was low. If a used face mask or a food container contaminated with blood goes into the wrong bin, the entire waste stream becomes hazardous. That means more material must be treated as infectious, putting additional strain on already limited treatment capacity.

Inadequate storage facilities compound the problem. Partner hospitals reported that they lack space and equipment to hold waste safely before collection. When collection is delayed — which happens frequently because TSD facilities are overburdened — waste piles up, increasing the risk of leaks, spills, and unauthorized dumping. A waste audit conducted by Healthcare Without Harm (HCWH) Southeast Asia across three partner hospitals found that plastics accounted for over 70 percent of total waste composition. At QMMC, that figure reached 84 percent. Most of this plastic comes from patient-care disposables, sanitary products, and medical textiles like aprons, masks, and gloves. Non-medical items — food packaging and bottles brought in by visitors — also contribute significantly, which means the problem is not confined to clinical areas.

Mercury: A Banned Substance That Hasn’t Gone Away

Since 2022, mercury-containing products have been banned in healthcare facilities under FDA Circular No. 2022-003. Thermometers, sphygmomanometers, dental amalgam capsules, and fluorescent lamps are no longer supposed to be in use. Most hospitals have shifted to mercury-free alternatives. But the stockpiles of old mercury waste remain. These stockpiles have not been properly disposed of, partly because there are few facilities equipped to handle mercury safely. If mercury waste is crushed or incinerated, the metal vaporizes and eventually settles into soil and water, where microorganisms convert it into methylmercury — a neurotoxin that accumulates in fish and poses risks to pregnant women and children.

What Gets Overlooked: The Role of Plastics and Chlorine in Toxic Emissions

Most discussions about healthcare waste focus on needles and infectious material. But a less visible threat comes from the chlorine content in plastics and disinfectants. When chlorinated materials — PVC plastics, chlorine-based disinfectants — are burned at low temperatures, they form unintentional persistent organic pollutants (uPOPs), specifically dioxins and furans. These compounds are highly toxic even in small amounts. They do not break down easily in the environment, and they accumulate in the fatty tissues of animals, concentrating as they move up the food chain.

The HCW Project’s approach to this problem is multi-pronged. It includes a policy gap analysis to identify weaknesses in existing regulations, hiring technical experts to recommend environmentally sound treatment technologies, and building stakeholder capacity through training. A key part of the strategy is reducing the use of chlorinated plastics and disinfectants in healthcare settings. The Toxics-Free Hospitals Campaign, launched during a national workshop in January 2026, promotes a 4Cs framework: Change old habits, Cut plastics, Commit to reuse, and Champion sustainability. The campaign introduces “Nurse Susie” as a friendly guide to help hospital staff and visitors adopt these practices.

One of the most practical recommendations from the HCWH audit is the shift toward reusable systems that maintain infection control standards. Reusable PPE, washable medical textiles, and durable patient linens could significantly cut the volume of single-use plastics entering the waste stream. This is not about compromising hygiene — it is about choosing materials and processes that can be safely sterilized and reused, which is already standard practice in many healthcare systems worldwide.

What Can Be Done: Practical Steps for Hospitals and Communities

The HCW Project is still in its early stages, but several concrete actions are already being implemented. These range from policy reforms to on-the-ground changes in how hospitals handle waste every day.

Improving Waste Segregation at the Source

The most effective way to reduce hazardous waste volume is to keep it separate from general waste from the moment it is generated. The project is developing standardized segregation protocols and training materials for hospital staff, patients, and visitors. For hospitals, this means color-coded bins, clear signage, and regular audits to ensure compliance. For the public, it means understanding that not all hospital waste is the same — and that putting a food wrapper in the wrong bin can turn a non-hazardous item into a disposal problem.

Adopting Low- or Zero-Emission Treatment Technologies

Open burning and old incinerators are being phased out in favor of technologies that do not produce dioxins and furans. Options include autoclaving (steam sterilization), microwave treatment, and chemical disinfection. These methods render infectious waste safe without combustion. The project is assessing which technologies are suitable for different hospital sizes and locations, and exploring opportunities for technology transfer and green financing to help facilities make the switch.

Managing Mercury Stockpiles Safely

Hospitals that still have mercury-containing devices need to identify, label, and store them securely until they can be transported to a facility equipped for mercury recovery. The project is working on improving waste inventory systems so that hospitals know exactly what they have and where it is. Proper storage means leak-proof containers in a well-ventilated, locked area away from heat sources. Disposal should only be handled by licensed TSD facilities that specialize in hazardous waste.

Reducing Single-Use Plastics in Healthcare

This is where the 4Cs framework comes in. Cutting plastics means evaluating every disposable item in a hospital and asking whether a reusable alternative exists. For items that must remain single-use — certain types of sterile packaging, for example — the focus shifts to choosing materials that do not contain chlorine, so that if they are eventually incinerated, they will not form dioxins. The project is also promoting the use of reusable face masks and other PPE, which became a topic of global discussion during the pandemic but has not been widely adopted in Philippine hospitals.

What to Watch For Next

The HCW Project has already expanded to include three new partner hospitals in Mindanao — Caraga Regional Hospital, Northern Mindanao Medical Center, and Southern Philippines Medical Center — bringing the total to six. The next phase will focus on implementing the policy recommendations, rolling out the Toxics-Free Hospitals Campaign more broadly, and securing green financing for technology upgrades. For communities near hospitals, the most immediate change to watch for is better waste segregation and fewer open burning incidents.
