Post-consumer plastic packaging waste from online food delivery services in South Korea.

Along with the rapid growth of the food delivery industry, concerns are growing regarding the management of plastic packaging waste. This study estimates the amount of plastic packaging from online food delivery services in Korea and assesses its environmental effects using life cycle assessments. This study also compares the environmental impacts of the adoption of multi-use containers, the use of recycled materials, and the increase in recycling rates proposed by the Korean government for efficient plastic waste management. A total of 72.93 kt of plastic packaging was consumed by online food delivery in 2020, polypropylene and polyethylene terephthalate accounted for 81.48% of the packaging materials consumed. The adoption of multi-use containers is the most environmentally effective alternative, but its negative impact on terrestrial ecotoxicity is approximately 5 times higher than that of others. Although the other two alternatives are 2-6 times less efficient than adopting multi-use containers, they can still play an important role in plastic waste management. Overall, these results provide empirical information on food packaging waste and insights into the sustainable management of plastics.
