塑料消费随着全球人口的增长而增加,并导致塑料废物的数量增加。有各种塑料废物管理策略;然而,目前的管理进展是不可持续的,塑料废物倾倒在垃圾填埋场仍然是最常用的策略。不可生物降解,塑料垃圾倾倒在垃圾填埋场会造成一些环境和人类健康问题。最近已经进行了许多研究以确定塑料废物处理的安全和生态有益的方法。本文使用计算方法对有关塑料废物管理的现有文献进行了书目分析。高度使用的关键字,最常引用的论文和作者,积极参与的国家,在书目分析过程中分析了出版物的来源。此外,讨论了各种塑料废物管理策略及其环境效益。已得出结论,在六种塑料废物管理技术中(垃圾填埋场,回收,热解,液化,道路建设和焦油,和混凝土生产),道路建设和沥青和混凝土生产是两种最有效的策略。这是由于显著的好处,例如易于本地化,减少温室气体排放,并增加了制造材料的耐用性和可持续性,结构,和道路。相反,由于相关的环境和人类健康问题,使用垃圾填埋场是最不可取的策略。回收有同样的好处和缺点。相比之下,热解和液化是有利的,由于生产焦炭和燃料,但是高的能量需求限制了它们的好处。因此,建议将塑料废物用于建筑应用。
Plastic consumption increases with the growing population worldwide and results in increased quantities of plastic waste. There are various plastic waste management strategies; however, the present management progress is not sustainable, and plastic waste dumping in landfills is still the most commonly employed strategy. Being nonbiodegradable, plastic waste dumping in landfills creates several environmental and human health problems. Numerous research studies have been conducted recently to determine safe and ecologically beneficial methods of plastic waste handling. This article performed a bibliographic analysis of the available literature on plastic waste management using a computational approach. The highly used keywords, most frequently cited papers and authors, actively participating countries, and sources of publications were analyzed during the bibliographic analysis. In addition, the various plastic waste management strategies and their environmental benefits have been discussed. It has been concluded that among the six plastic waste management techniques (landfills, recycling, pyrolysis, liquefaction, road construction and tar, and concrete production), road construction and tar and concrete production are the two most effective strategies. This is due to significant benefits, such as ease of localization, decreased greenhouse gas emissions, and increased durability and sustainability of manufactured materials, structures, and roadways. Conversely, using landfills is the most undesirable strategy because of the associated environmental and human health concerns. Recycling has equal benefits and drawbacks. In comparison, pyrolysis and liquefaction are favorable due to the production of char and fuel, but high energy requirements limit their benefits. Hence, the use of plastic waste for construction applications is recommended.
