Thermal Pyrolysis of Hospital Plastic Waste

Abstract

Plastic plays an important role in our daily lives due to its versatility, light weight and low production cost. The amount of plastic waste is growing every year and with that comes an environmental concern regarding this problem. Pyrolysis as a tertiary recycling process is presented as a solution. In this work, the pyrolysis of hospital plastic waste products was investigated using thermal non catalytic cracking techniques. The experimental work was carried out using a pyrolysis reactor operating under an inert atmosphere at 450°C. Results indicated that the waste plastic is able to give the yield of liquid product by using a pyrolysis reactor. The obtained product was fuel liked liquid heavy oil which was viscous and had a yellow color. The fuel properties of the diesel-range distillate (diesel fraction) were comparable to other conventional fuel and found its calorific value was 31 MJ/kg.

Biomedical waste plastic: bacteria, disinfection and recycling technologies—a comprehensive review

“…PE in the health care sector have been used in medical drip bottles IV controllers, biohazards waste polythene, pulmonary mouthpiece applications. Mahmud (2018) (Table 4) worked on the pyrolysis of waste obtained from the MP of different types of polyethylene like PE, HDPE and LDPE in a thermal non-catalytic cracking technique. They worked at an inert atmosphere temperature of 450 °C, a yellow viscous liquid fuel of 78.7% was produced with a calorific value of 31 MJ/Kg, which indicates that liquid fuels represent one kind of diesel fraction.…”
