Plastics have outgrown most man-made materials and have long been under environmental scrutiny. However, robust global information, particularly about their end-of-life fate, is lacking. By identifying and synthesizing dispersed data on production, use, and end-of-life management of polymer resins, synthetic fibers, and additives, we present the first global analysis of all mass-produced plastics ever manufactured. We estimate that 8300 million metric tons (Mt) as of virgin plastics have been produced to date. As of 2015, approximately 6300 Mt of plastic waste had been generated, around 9% of which had been recycled, 12% was incinerated, and 79% was accumulated in landfills or the natural environment. If current production and waste management trends continue, roughly 12,000 Mt of plastic waste will be in landfills or in the natural environment by 2050.
塑料的使用已超过大多数人造材料，长期以来一直受到环境审查。然而，目前缺乏全面的全球信息，尤其是关于其生命周期末端的命运。通过识别和综合聚合物树脂、合成纤维及添加剂的生产、使用和生命周期末端管理的分散数据，我们首次对所有大规模生产的塑料进行了全球分析。我们估计，迄今为止已生产了83亿吨原生塑料。截至2015年，已产生约63亿吨塑料垃圾，其中约9%被回收利用，12%被焚烧，79%则堆积在垃圾填埋场或自然环境中。如果当前的生产和废物管理趋势持续下去，到2050年，大约1.2亿吨塑料垃圾将被填埋或留在自然环境中。
