In the past, ordinary plastics would wear out with the number of cycles. After the plastics are crushed, they will be made into lower quality plastics. For example, a transparent plastic bottle can only be processed after reprocessing. Into lower grade plastic products such as carpets or pile fabrics.
Researchers from Colorado State University stated that humans urgently need to develop a reusable plastic. They recently invented a chemical recycling method that can decompose plastic into 'building blocks', purify it and convert it into plastic again. .
Dr. Jian-Bo Zhu and colleagues improved the existing plastics. They finally identified two catalysts that can efficiently decompose this polymer into constituent monomers, about 85% of which can be reused. .
Andrew Dove from the University of Birmingham in the United Kingdom stated: 'In the study of Dr. Zhu et al., used plastics can be recycled indefinitely without adversely affecting their performance. This opens the door to the new world. After the end of the plastic is no longer considered as waste, but has become a raw material that can create high-value products and native plastic.
