Status Analysis of Agricultural Waste Generated in Gangwon-do Using Statistical Tool

초록

This study aimed to comprehend the generation and treatment status of agricultural waste in Gangwon-do through statistical analysis. The average annual generation of agricultural waste, represented as synthetic resins in Gangwon-do over the past 5 years (2017-2021) was 26,057 tons/year with a coefficient value (CV) of 16.7%, which accounted for 8.3% of the nationwide amount. In Gangwon-do, low-density polyethylene (LDPE) exhibited the highest proportion among greenhouse LDPE, mulching LDPE, high-density polyethylene (HDPE), polyvinyl chloride (PVC), ethylene-vinyl acetate (EVA), and polyolefins (PO). In addition, it accounted for the largest share of mulching LDPE nationwide. The generation of agricultural waste in the form of pesticide containers in Gangwon-do over the past 5 years (2017-2021) amounted to 5,265,279 pieces/year with a CV of 8.1%, representing 7.3% of the nationwide total. The generation proportion ratio of plastic bottles (3,567,751 pieces/year, CV 8.7%) and plastic bags (1,697,528 pieces/year, CV 12.8%) in pesticide containers was approximately 2:1. The amount of agricultural waste generated by the 18 local governments of Gangwon-do exhibited a radial pattern, with a notable concentration in Hongcheon, Pyeongchang, and Hoengseong. As a result, it could be regarded as a focal point in the future when installing a treatment and recycling facility directly managed by the Korea Environment Corporation. The results of the correlation analysis conducted using SPSS revealed that factors such as agricultural land area or field cultivation area exhibited a higher correlation with the amount of agricultural waste generation than factors such as the number of agricultural populations or households engaged in field cultivation. © 2023, Korea Society of Waste Management.
