Since crude oil serves as the initial material for plastic production, the reverse processing of plastic back into crude oil represents an innovative method employed in the present work for improved plastic disposal. Initially, the long-chain molecules of waste plastics are broken down into shorter chain molecules, which are then further fragmented into smaller molecules using a catalytic cracker. The resulting product is a mixture of oils including gasoline, diesel, kerosene, and similar substances. The machinery and processes involved in oil production are entirely based on environmentally friendly principles. Plastics suitable for conversion into oil include propylene, used garbage bags, cookie packaging, CD cases, polyethylene found in vinyl bags, medical products, PET bottle caps, and polystyrene used in cup noodle bowls, lunch boxes, Styrofoam, etc. In addition to addressing the challenges of plastic waste management, the innovative process outlined in this work underscores a commitment to environmentally conscious practices. By employing catalytic cracking and adhering to sustainable principles throughout the oil production process, the conversion of waste plastics into valuable resources not only mitigates environmental impact but also contributes to the circular economy. The types of plastics suitable for this conversion encompass a wide range of commonly used materials, further highlighting the potential for widespread adoption and impact in reducing plastic pollution. Through this approach, the journey from crude oil to plastic and back to oil demonstrates a holistic and efficient method for managing plastic waste while promoting sustainable resource utilization.
