Biofuel from plastic waste

Plastic waste is a major environmental problem and at the same time a great energy potential. One of the possibilities of disposing of waste plastics is the production of liquid fuel. In this paper, technological, ecological and economic aspects of liquid fuel production from plastic waste are analyzed. Analyzes show that the process of obtaining fuel by pyrolysis with a catalyst is a technologically mature technology, although there is still room for improvement. The most commonly used catalysts are zeolite based. Up to 800 liters of liquid fuel can be obtained from one ton of waste plastic, although up to 450 liters are usually obtained in real plants. The quality of the obtained fuel largely depends on the quality and contamination of the raw material, and its price is slightly higher than conventional oil-based fuel. The total amount of plastic waste in Croatia is 266, 384 tons, which represents a potential for obtaining up to 213 million liters of fuel per year. Since a large amount of plastic waste without impurities is needed for commercial production, it is necessary to improve the existing infrastructure for separate collection of plastic waste in Croatia. The environmental benefits of disposing of waste plastics by producing liquid fuels are great, including the reduction of greenhouse gas emissions.
