CEBU CITY — The Environmental Management Bureau in Central Visayas (DENR-EMB 7) issued a warning on March 30, 2026, cautioning the public against attempting to extract fuel from PET bottles using do-it-yourself (DIY) methods involving heating or burning. This warning comes in response to the proliferation of viral videos on social media demonstrating this practice.
The agency emphasizes that these methods are dangerous and can release harmful substances, specifically polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs). These chemicals are known carcinogens and pose significant health hazards when plastics are heated without proper controls.
Dangers of Uncontrolled Pyrolysis Processes
According to DENR-EMB 7, while pyrolysis is a legitimate waste-to-energy technology in some countries, it requires stringent conditions to be safe. These include controlled temperatures between 800 and 1,200 degrees Celsius and the use of air pollution control devices. The DIY methods circulating online lack these critical safety measures.

The bureau stressed that these uncontrolled processes do not eliminate the formation of PCDDs and PCDFs. Furthermore, without air pollution control devices, the pollutants released during these DIY extractions pose substantial risks to both human health and the environment.
Health Risks Associated with Toxic Emissions
The primary concern is the release of PCDDs and PCDFs, which are highly toxic and persistent environmental pollutants. Exposure to these chemicals can lead to a range of health problems, including developmental issues, immune system suppression, endocrine disruption, and an increased risk of cancer. These substances can accumulate in the food chain, posing a long-term threat to both human and animal health.
The DENR-EMB 7 urges the public to avoid these dangerous practices, highlighting that they are not a viable or safe alternative fuel source. The potential health and environmental consequences far outweigh any perceived benefits.
Proper Pyrolysis as a Waste-to-Energy Solution
It's crucial to understand the difference between the dangerous DIY methods and the controlled pyrolysis processes used in some countries for waste-to-energy production. Proper pyrolysis involves the thermal decomposition of organic materials, including plastics, at high temperatures in the absence of oxygen. This process can produce liquid by-products that can be used as fuel.
However, the key difference lies in the operating conditions. Industrial-scale pyrolysis plants maintain precise temperature controls and employ advanced air pollution control technologies to minimize the formation and release of harmful emissions. These facilities are designed to meet strict environmental standards and protect public health.
Impact on Air Quality and Environment
Uncontrolled burning or heating of plastics, as seen in the DIY fuel extraction videos, releases a cocktail of pollutants into the air. These pollutants contribute to air pollution, respiratory problems, and other health issues. They can also contaminate soil and water sources, posing long-term ecological risks.
The DENR-EMB 7 emphasizes the importance of proper waste management practices and the need to avoid methods that can harm the environment and human health. Promoting responsible waste disposal and supporting legitimate waste-to-energy initiatives are crucial steps towards a sustainable future.

Community Awareness and Education is Key
Effective public awareness campaigns are essential to educate communities about the dangers of DIY fuel extraction methods and the importance of responsible waste management. By providing accurate information and promoting safe alternatives, local government units and environmental organizations can empower individuals to make informed decisions that protect their health and the environment.
Looking Ahead: Promoting Sustainable Alternatives
Moving forward, it is essential to prioritize and promote genuine sustainable fuel alternatives, such as renewable energy sources. Investment in solar, wind, and other clean energy technologies can provide a long-term solution to the country's energy needs while minimizing environmental impact. Public awareness and support for these initiatives are critical to achieving a more sustainable future for the Philippines.
The Department of Energy (DOE) and other relevant agencies should also strengthen regulations and enforcement to prevent dangerous DIY practices and ensure that any waste-to-energy initiatives adhere to strict environmental standards. Collaboration between government, industry, and communities is essential to address the challenges of waste management and energy security in a responsible and sustainable manner.
The DENR-EMB 7 urges residents of Central Visayas and the wider Philippine public to report any observed instances of dangerous DIY fuel extraction activities to the authorities for appropriate action. By working together, we can protect our environment and safeguard the health and well-being of our communities.
