Why don't we just burn plastic?

We don't just burn plastic because burning plastic creates serious environmental and health problems and wastes resources. When plastic is burned, especially in open burning or low-temperature incineration, it releases toxic chemicals such as dioxins, furans, benzene, and hydrochloric acid, which cause air pollution, contribute to climate change by releasing carbon dioxide, and pose health risks like respiratory illness and cancer for people nearby. Burning also releases heavy metals if plastic contains additives. While modern high-temperature waste-to-energy incinerators with advanced filters can burn plastic more safely and capture energy, they are expensive to build and operate, still produce carbon emissions, and leave behind toxic ash that must be disposed of in special landfills. Burning also destroys material that could be recycled or reused, making it unsustainable long-term. Additionally, plastics are made from fossil fuels, so burning them releases stored carbon. Instead, better solutions include reducing plastic use, reusing, recycling where possible, and developing biodegradable alternatives and improved recycling technologies. Open burning of plastic is illegal in many places due to pollution laws and harms air quality.
