The effectiveness of plastic waste pyrolysis reactor with a zeolite catalyst as an appropriate technology in producing kerosene


Salma Aripin et al. View all

Solid Waste Management

Plastic waste is harmful to the environment due to its long-term decomposition process. Plastic waste is made out of hydrocarbon polymers, its chain bonds do not naturally decompose physically, chemically, or biologically. The plastic waste generated in Indonesia reaches up to 175,000 tons per day...
