摘要

化石基塑料问题是一个悖论,提出的解决方案相互矛盾。虽然理想化的愿景提倡将生物降解塑料作为最终解决方案,但现实情况是,化石基塑料在生产中占主导地位,约占 99%。尽管生物降解塑料在概念上很有吸引力,但其实际应用仍然有限,产量极低。因此,当前的塑料废物管理系统面临着挑战,塑料废物总量中仅有 25% 被回收利用。约 31.2% 的塑料废弃物被焚烧,43.8% 的塑料废弃物被填埋或被不当处理,这反映了一种不可持续的方式。根据预测,到 2050 年,回收率有可能提高到近 44%,但焚烧率仍高达近 50%,令人震惊。为了实现可持续增长,创造一个无碳、无毒的环境,有必要再次承诺加快塑料废物的再利用和回收。否则,尽管化石基塑料对社会和环境做出了重大历史贡献,但仍有可能使人们对化石基塑料的谴责永久化。

Sustainable Development Growth in the Plastic Industries is Promising or Just a Hoax: Past, Present, and Future aspects on Global Perspective
The issue of fossil-based plastics presents a paradox, with conflicting solutions proposed. While an idealistic vision promotes biodegradable plastics as the ultimate solution, the reality is that fossil-based plastics dominate production, constituting approximately 99%. Despite the conceptual appeal of biodegradable plastics, their practical implementation remains limited with minimal production. Consequently, the current plastic waste management system faces challenges, with only 25% of total plastic waste being recycled. A significant portion, around 31.2%, is incinerated, and 43.8% ends up in landfills or is improperly disposed of, reflecting a non-sustainable approach. Projections suggest a potential increase in recycling rates to nearly 44% by 2050, but incineration remains alarmingly high at close to 50%. To achieve sustainable growth and create a carbon and toxic-free environment, there is a need for a renewed commitment to accelerate the reuse and recycling of plastic waste. Failure to do so risks perpetuating the condemnation of fossil-based plastics, despite their significant historical contributions to society and the environment.
