ABSTRACT The high-density polyethylene (HDPE) plastic bags, more commonly known as "kantong kresek" in Indonesian, have become the most prevalent plastic waste polluting the environment. The plastic, composed of long-chain hydrocarbon molecules, is highly resistant to natural degradation, necessitating technologies that can manage plastic waste without creating new waste. The pyrolysis pro…
