Gorgeous counter attack: how strong is the regeneration of waste plastics?

Due to the non degradability of plastics, it has become the number one enemy of mankind. But the existence of all things in the world has its value. If it is recycled well, it is also a friend of mankind. How to reduce the environmental pollution caused by waste plastics? The research and development of recycled plastics and biodegradable plastics is the only way for plastics to be good.

Do you remember the report about waste plastics building roads not long ago? On the 52nd World Earth Day (April 22), China's first recycling road for waste plastics was officially opened in Xuhui campus of East China University of science and technology. This 300 meter "plastic road" uses Dow's innovative elvaloy? RET asphalt modification technology, more than 6000 waste milk bottles and other plastic wastes are used to pave polymer modified asphalt (PMA) roads.

Besides building roads, waste plastics can create more……

trunk

Quality circular polymers (QCP), a plastic recycling joint venture between Suez and Lyondell Basel, has adopted recycled materials for a new luggage line. The trunk is made of recycled plastic. In the new suitcase series, the large-size suitcase contains the equivalent of 483 yogurt cups and 14 plastic bottles of recycled material. Its outer shell is made entirely of recycled plastic, and its inner fabric is made of 100% recycled PET bottles.

chair

Tom Robinson, a London designer, designed and made the chair "evolve" using 100% recycled plastic extracted from e-waste. At the end of the chair's life, plastic parts can be recycled and metal connectors can be reused“ All walks of life will favor natural materials, but considering the 6.3 billion metric tons of waste plastics we produce on the earth, I think it is necessary for us to find a reasonable way to make use of these flexible material resources, so as to save the use of raw materials. " Robinson said.

Building brick

Byfusion from the United States is committed to building sustainable buildings. After several years of research and development, the company has built the first byblock building brick made entirely of recycled plastic. Heidi kujawa, chief executive of the company, said that in the past few years, the company has been working hard to develop innovative systems to help the recycling industry solve the plastic waste crisis by recycling plastics that were previously thought to be irrecoverable.

Mobile phone case

Lander, an outdoor brand, has launched a new environmentally friendly protective case designed for Apple's iPhone 12. The popular upgraded version of Torrey series protective case adopts Eastman tritan ™ Renew sustainable materials. Torrey series protective shell is made of soft touch bio based plastic on the outer layer and hard protective layer made by tritan renew on the inner side. In addition to using environmentally friendly materials, lander also uses 100% recyclable non plastic materials for product packaging, uses soybean ink for printing, and adopts corresponding sustainable strategies in logistics and transportation to reduce its carbon footprint.

electric vehicle

The Tu / ecomobile student team at the University of technology Eindhoven in the Netherlands has launched an electric car Luca, which is almost entirely made of waste plastic. Luca's body, surface treatment, windows and interior are made of recycled materials, including PET bottles, ABS and household waste. The base is made of flax and recycled plastic, mostly from plastic that has been fished from the ocean.

Thermostat, intelligent speaker

The environmental pollution of plastic products is great. From the principle of protecting the environment, saving resources for human survival and the community of human destiny, countries all over the world attach great importance to the recycling of plastic waste, which is an effective measure to take the road of sustainable development and circular economy, and the corresponding requirements for its recycling and regeneration technology are also high. At present, the recycling methods of plastics include: melting regeneration, pyrolysis, energy recovery, chemical raw materials recovery and other methods.

With the application of new technology and new equipment, the recycling of waste plastics is developing from single physical recovery to diversified environmental protection disposal. For example, Sinopec has carried out comprehensive research on the pretreatment of waste plastics and the post-processing technology of plastic oil, and will cooperate with professional waste plastics recycling enterprises to complete waste plastics recycling and oil production, and explore value-added schemes for the utilization of plastic pyrolysis oil in the future. Among them, the whole set of waste plastic oil production technology developed by the Academy of petroleum sciences can meet the national six vehicle fuel standards in terms of product quality, significant economic benefits and large-scale production.

In recent years, China's waste plastic recycling volume has gradually increased. In 2019, the waste plastic recycling volume will reach 18.9 million tons, accounting for 23.09%. In the future, the waste plastics in China's landfills will be disposed innocuously, up to 1 billion tons.
