Current Prospects for Plastic Waste Treatment

Polymers, Год журнала: 2022, Номер 14(15), С. 3133 - 3133

Опубликована: Июль 31, 2022

The excessive amount of global plastic produced over the past century, together with poor waste management, has raised concerns about environmental sustainability. Plastic recycling become a practical approach for diminishing and maintaining sustainability among management methods. Chemical mechanical are typical approaches to waste, simple process, low cost, environmentally friendly potential profitability. Several materials, such as polypropylene, polystyrene, polyvinyl chloride, high-density polyethylene, low-density polyurethanes, can be recycled chemical approaches. Nevertheless, due waste’s varying physical properties, separation becomes challenge. Hence, reliable effective technology is critical increasing value rate. Integrating technologies would an efficient method reducing accumulation contaminants by especially in industrial uses. This review addresses recent advances technology, mainly recycling. article also discusses current various materials.

Sustainable recycling technologies for thermoplastic polymers and their composites: A review of the state of the art

Polymer Composites, Год журнала: 2022, Номер 43(9), С. 5831 - 5862

Опубликована: Авг. 20, 2022

Abstract This review article discusses the environmental and economic effects of recycling, as well sustainable thermoplastic polymer recycling technologies. Several researchers have utilized recycled thermoplastics matrices in production a variety natural synthetic‐based composites, which is also focus this study. All industries (food packaging, construction building, transportation, indoor usage) where large market share are covered review. The desirable properties polymers, such corrosion resistance, low density, user‐friendliness, caused plastic to surpass aluminum other metals use over past 60 years. Furthermore, one most important measures available mitigate these dynamic segments plastics industry at present. Increased landfilling incineration negative impact on ecosystem, continued increase virgin fossil has environment. Consequently, continuous could lead depletion fuel resources, an emissions during processing, eventual incineration. Increasing numbers nations adopting circular economy concept effort avoid all problems. emphasizes reuse products materials according waste hierarchy, rather than their cremation or disposal

Advancing Plastic Recycling: Challenges and Opportunities in the Integration of 3D Printing and Distributed Recycling for a Circular Economy

Polymers, Год журнала: 2023, Номер 15(19), С. 3881 - 3881

Опубликована: Сен. 25, 2023

The concept of the circular economy has emerged as a promising solution to address mounting concerns surrounding plastic waste and urgent need for sustainable resource management. While conventional centralized recycling remains common practice waste, facilities may prove inadequate in handling ever-increasing volumes generated globally. Consequently, exploring alternative methods, such distributed by additive manufacturing, becomes paramount. This innovative approach encompasses actively involving communities practices promotes economy. comprehensive review paper aims explore critical aspects necessary realize potential manufacturing. In this paper, our focus lies on proposing schemes that leverage existing literature harness manufacturing an effective We intricacies process, optimize 3D printing parameters, challenges, evaluate mechanical properties recycled materials. Our investigation draws heavily from last five years, we conduct thorough assessment DRAM implementation its influence structures. Through analysis, reveal materials delivering functional components, with insights into their performance, strengths, weaknesses. serves guide those interested embracing transformative recycling. By fostering community engagement, optimizing processes, incorporating suitable additives, it is possible collectively contribute more future while combatting crisis. As progress made, essential further delve complexities material behavior, techniques, long-term durability printed components. addressing these challenges head-on, feasible refine advance viable pathway minimize cultivating cleaner planet generations come.
