Study on the production and recovery level of waste PET drinking bottles in China

State Environmental Protection Key Laboratory of Eco-Industry, Chinese Research Academy of Environmental Sciences

摘要

摘要: 聚对苯二甲酸乙二醇酯（PET）饮料瓶属一次性塑料包装，应用广泛且周期短，废弃量大，从节约资源、减少碳排放和保护环境等方面看，废PET饮料瓶回收都具有重要的意义。基于PET瓶装的饮料产量和PET瓶消费量的正相关性，建立了饮料总产量－PET瓶装的饮料产量－废PET饮料瓶产生量（PET饮料瓶消费量）间的数量响应关系，结合灰色模型，预测2020—2025年我国废PET饮料瓶的产生量；根据国内PET饮料瓶回收现状和物质代谢定性分析，确定了废PET饮料瓶的主要流向；通过问卷调查和现场实测，测算出现阶段我国PET饮料瓶回收总体水平。结果表明：2020—2025年，我国废PET饮料瓶的年产生量预测值为370万~409万t，主要流向回收利用体系、餐厨垃圾处理厂、垃圾填埋场、垃圾焚烧发电厂以及海滩等地，其中流向餐厨垃圾处理厂、垃圾填埋场、垃圾焚烧发电厂、海滩等地的废PET饮料瓶所占比例总体低于5%，即全国废PET饮料瓶回收率在95%以上，处于较高的回收水平。

Abstract: Polyethylene terephthalate(PET) drinking bottles are a kind of disposable plastic packaging, which are widely used with a short cycle and a large amount of waste. From the perspectives of saving resources, reducing carbon emissions and protecting the environment, the recycling of waste PET drinking bottles is of great significance. Based on the positive correlation between the output of PET bottled drinks and the consumption of PET bottles, the quantity response relationship among “total output of drinks - output of PET bottled drinks - production or consumption of PET bottles” was established. Combined with grey model, the waste PET drinking bottle production from 2020 to 2025 in China was predicted. According to the status of PET drinking bottles recycling and qualitative analysis of material metabolism, the main flow directions of waste PET drinking bottles were determined. Through questionnaire surveys and field measurements, the overall level of PET drinking bottles recycling in China at the present stage was calculated. The results showed that, from 2020 to 2025, the annual production of waste PET drinking bottles in China would be in the range of 3.7 million to 4.09 million tons, and they would mainly flow to the recycling system, kitchen waste treatment plants, landfills, waste incineration power plants and beaches. And the total proportion of waste PET drinking bottles flowing to kitchen waste treatment plants, landfills, waste incineration power plants and beaches would be less than 5%, that is, the recycling rate of waste PET drinking bottles would be more than 95% in China on the whole, being at a relatively high recycling level.
