Recycled Plastics Utilization in Packaging Converting Processes: A Semi‐Systematic Review
AI summary Read the abstract
This semi-systematic review assessed how extrusion and injection molding converting techniques can produce food and non-food packaging from recycled plastics, identifying enhanced sorting, cleaning, and chemical recycling as key quality-improvement drivers. Improving the quality and scalability of recycled plastic packaging is essential to closing the loop on plastic waste and reducing the virgin plastic production that ultimately feeds microplastic pollution.
In recent years, increased plastic usage has led to huge amounts of blended plastic waste moving into the environment without proper control. Packaging plastics make up one‐half of all waste and plastics disposal poses a significant environmental issue. Consequently, the need for improved recycling of waste plastics and their conversion into new products to decrease the need for additional virgin plastics has increased overtime. Given the growing demand for sustainable packaging solutions, this study examines various converting techniques, including extrusion and injection molding, to assess their effectiveness in the production of food and nonfood packaging from recycled plastics. The study underscores the role of advances in recycling technology and considers how challenges like variability in quality and process compatibility can be addressed. It is noted that enhanced sorting and cleaning methods and chemical recycling play a critical role in the quality and performance improving of recycled plastics. The article emphasizes the potential of recycled plastics for creating high‐quality packaging while reducing environmental impact. Future research efforts should focus on enhancing recycling techniques and expanding applications of recycled plastics to promote increased sustainability within the packaging industry.

AI summary Read the abstract
This review examined the effectiveness of plastic recycling as a solution to plastic pollution, finding that global recycling rates of only 9% are insufficient given annual production exceeding 400 million metric tonnes. The authors identified key gaps in recycling efficiency for thermoset plastics and proposed advanced recycling methods, design-for-recyclability principles, and the Global Plastics Treaty as emerging solutions.
Emerging Technologies for Converting Mixed Plastic Waste into Biodegradable Polymers
AI summary Read the abstract
Scientists are developing new ways to turn mixed plastic waste (like food containers and shopping bags) into biodegradable materials that naturally break down instead of polluting the environment. This research review summarizes promising techniques that could help reduce the microplastics that end up in our food and water. If these methods can be made affordable and used widely, they could significantly cut plastic pollution and the health risks it poses to humans.
