The hottest recyclable ultimate plastic is success

  • Detail

The ultimate plastic that can be recycled has been successfully developed

plastic is very common in people's lives, from electronic equipment to parcels and vehicles, but the waste plastic after use is difficult to decompose. The liquid crystal rubber tensile testing machine adopts line drive encoder with strong anti-interference ability. It usually won't rot for hundreds of years. When they burn, they may make chemicals enter the environment and produce toxic substances in the air. Recently, researchers at North Dakota State University (NDSU) in the United States have developed a new type of plastic, which can be degraded and reduced to molecules under special light, and these molecules can also produce new plastics again. Relevant papers were published in the recently published "Applied Chemistry"

the research team made a molecular solution from fructose in fruits and then converted it into plastics (polymers). According to physicists' organization, the plastic can be completely decomposed into its original soluble molecules after being exposed to ultraviolet light of 350 nm for 3 hours

"real sustainable utilization includes the decomposition of materials into their basic substances. Talent education has proved that we can decompose them into basic substances and regenerate polymers." Mukund Sibi of the school's Center for sustainable materials science said. They use oil seeds, cellulose, lignin and sucrose in crops to produce the basic molecules of plastics, and then synthesize the basic molecules into polymer molecules to finally form plastics

"this' cradle to cradle 'approach has brought a new kind of plastic, which can be easily degraded, and also provides a scientific possibility for people to reduce their dependence on fossil fuels and raw materials when producing end products." Dean Webster, a professor in the Department of paint and polymer materials, said

"our strategy is likely to use biomass to create new materials, which will be degraded by light after use, reducing the pressure of harmful chemicals in the environment." Sivaguru geraman said

the university has established a sustainable materials science center in conjunction with the North Dakota experimental project incentive competition research (nd epscor), and several experimental groups have combined biomass and renewable resources to produce polymers and mixtures. Sibi's laboratory is responsible for the production of monomers and bio based triggers. Sivagulu's team specializes in photochemistry and photodegradation, while Webster's team is studying the product compound chemistry that poly food contact materials are not produced in a one-stop manner. "Through teamwork, we can complete this research. We need everyone's expertise to solve this problem." Spey said

researchers also pointed out that before making this plastic from biomass into products and commercializing it, further research is needed to evaluate its durability and strength. That is, "what is the best trigger to decompose plastic? What is the best monomer? What is the best polymer we can make?" Spey said. In the next two years, they will also use this kind of plastic in cars, electronic equipment and other equipment to test their working performance
