Abstract
Plastic waste generation makes the second largest contribution of 18.6% to the total generation of municipal solid waste. Plastic waste often becomes a problem in the environment because it does not decompose easily. Polyethylene terephthalate (PET) is one type of plastic waste. This paper aims to provide a general review of the potential for using nuclear energy in the form of irradiation techniques in assessing the life cycle of PET plastic waste. The research method used is a literature study based on several related studies. The life cycle assessment method can be used to analyze potential uses and their impacts. Life cycle assessment consists of the stages of determining objectives and scope, life cycle inventory analysis, life cycle impact assessment, and interpretation. A SWOT analysis of the PET sorting program from generation sources is needed as a complement to the life cycle assessment analysis. The potential for PET irradiation techniques is in two ways, namely direct and indirect. The first way, is PET plastic waste is exposed to a certain dose of radiation directly to degrade the material properties of PET plastic waste. The second way, PET plastic waste is substituted into other products, and then a certain dose of radiation is given. At the stage of determining life cycle goals, for example, measuring the impact of irradiation techniques on the reuse or recycling of PET plastic waste. The scope is limited to “gate to gate”, from receiving PET plastic to PET irradiation. The functional unit as a basic unit can be used based on 1 kg of PET plastic. The use of nuclear power through irradiation techniques has the potential to be used in processing PET plastic. Keywords: irradiation, polyethylene terephthalate (PET), life cycle assessment
