Novel chemical recycling system for vinyl polymers of cyclic styrene derivatives

Chemical recycling of widely used vinyl polymers (VPs) is one of the key technologies required for realizing a sustainable society. In this regard, a team of researchers from Shinshu University have recently reported a new chemical process that facilitates the depolymerization of cyclic styrene-based VPs, resulting in the recovery of a monomer precursor. This highly efficient chemical recycling system can help with effective resource circulation and the development of new plastic recycling technologies. Vinyl polymers (VPs) are one of the most widely used plastic materials. They are found everywhere, from poly(vinyl chloride) pipes and surgical gloves to disposable polystyrene plates. Given the global call for a move towards sustainability, would it not be great to chemically recycle this widely used polymer for realizing a sustainable society?

Nurdles have a significant impact on the environment long before they are formed, as well. The vast majority of the plastics plants in the United States are located alongside communities of color, which are disproportionately impacted by industrial pollution. Those plants emit a toxic mixture of pollutants including ethylene oxide, styrene, and benzene; there are so many petrochemical plants located between Baton Rouge and New Orleans that the area has become known as “cancer alley.”

Gas Leak at Indian Plastics Plant Kills at Least 11, Sends Hundreds to Hospitals

A major gas leak at a petrochemical plant in the eastern, industrial port city of Visakhapatnam, India has killed at least 11 people and sent hundreds to the hospital, according to the most recent figures from India Today.

Excerpt from this story from EcoWatch:

A major gas leak at a petrochemical plant in the eastern, industrial port city of Visakhapatnam, India has killed at least 11 people and sent hundreds to the hospital, according to the most recent figures from India Today.

The leak occurred around 2:30 a.m. Thursday at the LG Polymers chemical plant, when styrene leaked out from two 5,000 tonne (approximately 5,512 U.S. tons) tanks that had been left unattended due to India's coronavirus lockdown, police said, as The Guardian reported.

"Because of the leakage of the said compound gas hundreds of people have inhaled it and either fell unconscious or having breathing issues," greater Visakhapatnam municipal corporation commissioner Srijana Gummalla said on Twitter.

Naik said at least 1,000 people were hospitalized, while Rani put the number at a lower 300 to 400, according to Reuters. A further 1,500 people were evacuated.

The plant's manager, South Korea-based LG Chem, said the leak was now contained.
