Recycled (Bio)Plastics and (Bio)Plastic Composites: A Trade Opportunity in a Green Future
AI summary Read the abstract
This review covers the recycling of thermoplastic, thermoset, biopolymer, and composite materials, discussing the technical and market challenges of creating high-quality secondary raw materials. The authors argue that improved material specificity, cleanliness standards, and integrated market systems are needed to make plastic and bioplastic recycling a commercially viable circular economy opportunity.
Today's world is at the point where almost everyone realizes the usefulness of going green. Due to so-called global warming, there is an urgent need to find solutions to help the Earth and move towards a green future. Many worldwide events are focusing on the global technologies in plastics, bioplastic production, the recycling industry, and waste management where the goal is to turn plastic waste into a trade opportunity among the industrialists and manufacturers. The present work aims to review the recycling process via analyzing the recycling of thermoplastic, thermoset polymers, biopolymers, and their complex composite systems, such as fiber-reinforced polymers and nanocomposites. Moreover, it will be highlighted how the frame of the waste management, increasing the materials specificity, cleanliness, and a low level of collected material contamination will increase the potential recycling of plastics and bioplastics-based materials. At the same time, to have a real and approachable trade opportunity in recycling, it needs to implement an integrated single market for secondary raw materials.
