    This research evaluated the environmental impact of waste film used in the farming industry which is subject to voluntary agreement by Waste Charge System using Life Cycle Assessment (LCA). When analyzing the environmental scores applying weighted values, production of raw materials, production of goods and disposal had nearly 73%, 15% and 11% of contribution to the environmental impact and also, amongst impact categories, resource depletion and global warming had 63% and 32% of contribution respectively. For resource depletion which had the highest contribution, production of raw materials, production of goods and disposal occupied around 86%, 9% and 4% of it, and the impact category of resource depletion that belongs to production of raw materials, accounted for about 54% of the whole environmental score, Here, over 95% of it was caused by crude oil. When investigating the contribution of each phase to global warming that is the key issue of low carbon green growth, production of raw materials, production of goods and disposal had respectively, 45%, 28% and 27% of contribution. As the result, production of goods and disposal had higher contributions than resource depletion. The entire contribution of production of goods and disposal to global warming was about 17%, and it is predicted that it would bring a huge impact, considering the possibility of establishing improvement plans. In the production of goods, electricity consumed was the main cause of global warming, and electricity used in the recycling process and incineration occupied approximately 52% and 45% of the disposal stage. In conclusion, we should pay attention to energy used in the production of goods and recycling for improving an environmental competitiveness of goods, and reduction of energy would be able to satisfy economic feasibility and environmental efficiency of the whole process of agricultural PE film.
