Utilization of Plastic Wastes for Sustainable Environmental Management: A Review

Abstract

The advancement and modernization of industries have provided numerous benefits to human life including diversification of manufacturing a wide range of products made from plastic materials, thereby leading to the generation of huge quantities of plastic waste. Owing to the increasing issues related with plastic waste, recycling methods have attracted much interest. Recycling not only protects the environment and resources for future generations but also reduces energy consumption and greenhouse gas emissions. A wide range of valuable products including char, oil, fuels, sorbent materials, and chemicals can be obtained through different techniques. This Review highlights various sustainable research avenues and potential routes to reduce the environmental impact of plastic waste based on both traditional and potential approaches for its utilization.

Investigation of the physical-mechanical properties and durability of high-strength concrete with recycled PET as a partial replacement for fine aggregates

“…Concrete is one of the most popular and used building materials in the world (Kılıç et al, 2003;Topçu and Uygunoğlu, 2007;Akçaözoğlu et al, 2010;Khan et al, 2021b;Kumar et al, 2021;Khan et al, 2022d). Per year, "around 12 billion tonnes of concrete are produced worldwide, which is approximately 10 billion tonnes of rock (Shah and Wang, 2004).…”

Recent Research Advancements in Catalytic Pyrolysis of Plastic Waste

“…The utilization of secondary sources as raw materials by manufacturers of chemicals and materials is a requirement for the establishment of value chains for chemical recycling that is economic, practical, and sustainable. 8,9 Among all the thermochemical techniques, pyrolysis can be considered more effective and efficient due to its distinct advantages, such as high flexibility of feedstocks, requiring low cost to construct, ease of use, and production of a potential range of hydrocarbons from plastic waste. 10 Pyrolysis, commonly known as thermolysis, is one of the most significant chemical recycling methods that convert waste into energy.…”

Mechanochemistry Milling of Waste Poly(Ethylene Terephthalate) into Metal–Organic Frameworks

“…Generally, the methods of treating plastic wastes include landfill, incineration, mechanical recycling, and chemical upcycling [6] . Traditional landfill and incineration invade valuable land space and/or cause noxious gas emission [7] . Mechanical recycling usually leads to low‐quality products [8] .…”

“…[6] Traditional landfill and incineration invade valuable land space and/or cause noxious gas emission. [7] Mechanical recycling usually leads to low-quality products. [8] In contrast, chemical upcycling, which can convert plastic wastes into high-quality monomers/oligomers or high-value chemical products, has drawn great attention for the sustainability and profitability.…”
