In China, the food delivery packaging waste is increasing due to the rapid growth of the sector and the use of single-use packaging to transport the meals. In addition, the recycling rates of current municipal waste management are low. In this regard, this study aims at estimating the climate change impact of current food delivery packaging and its waste treatment, by performing a Life Cycle Assessment with a cradle-to-grave approach. In addition, this article explores the potential benefits of increasing the current recycling rates, the recycled content of the packaging as well as the use of reusable packaging. For this study, the food packaging of a typical dumpling-based meal of the popular Chinese restaurant Xijiade was selected. Based on this menu and the current Chinese consumption patterns, the food delivery packaging in China would have emitted about 13 million tons of CO₂eq. Increasing current recycling rates to 35% would reduce 16% the emissions of single-use packaging, and further decrease (60%) could be found if half of the packaging was made of recycled material. In addition, if single-use packaging was replaced by reusable PP-based packaging (food container and carrier bag), the emissions would potentially be 63% lower than the current situation. In this case, doubling the recycling rates and the recycled content of the reusable food packaging would represent an extra 6 and 17% reduction of emissions, respectively.
