餐饮品类与城市空间差异下的餐饮外卖行业塑料垃圾产生特征分析
Characteristics of plastic waste generation from food delivery industry differentiated by catering types and urban space
摘要
Abstract
Food delivery industry developed rapidly in recent years,making it a crucial issue for mitigating land-based plastic waste.Profiles of plastic waste generation from food delivery are fundamental for precisely controlling plastic pollution for cities;however,its spatial characteristics remained unclear.In this work,5 456 food delivery restaurants in four categories of urban functional zones in Beijing,China were studied to find the spatial differences of plastic waste generation.Main results were:1)The plastic waste generated per order ranges from 3.05 to 1 120.10 g,that of the hot pot was the greatest and western food was the lowest.2)Polypropylene was the main component of plastic waste generated from food delivery,accounting for 76.27％±6.17％of the plastic packaging,followed by the composite packaging(incl.,polyethylene,aluminum foil,and pearl cotton),accounting for 15.96％±4.37％of the plastic packaging.3)Per unit area and per capita plastic waste generation from the food delivery industry showed spatial differences,i.e.,campus zone＞commercial zone＞residential zone＞industrial zone;the campus zones produced 3.29 times plastic waste than the industrial zones.Space-specific policy recommendations were put forward for improving plastic waste management of food delivery industry.关键词
