Waste sulfur polymers to assist plastic recycling

Waste sulfur polymers to assist plastic recycling

A new study published in Chemistry – A European Journal, suggests the problem of plastic waste could be addressed via waste sulfur polymers.

Study co-director Justin Chalker of Flinders University said researchers are working to develop a range of versatile and recyclable materials by controlling physical and mechanical properties, bringing them closer to scale up for manufacturing.

“Polymers made from elemental sulfur have emerged as versatile materials for energy storage, optics applications, environmental remediation and agriculture,” Mr Chalker said.

“Controlling their properties takes a big step towards these new polymers being able to replace plastics, rubber and ceramics that are currently unrecyclable.”

According to Mr Chalker, research found the new polymers could be broken down and reformed into new materials.

“This represents a new era in recyclable materials made from renewable building blocks such as plant oils and industry by-products such as sulfur,” Mr Chalker said.

University of Liverpool collaborator Tom Hasell said the research is another important set towards taking sulfur-based polymers out of lab, for use in every-day practical material.

“Being able to produce polymers from sulfur – a waste product of the petrochemical industry – is a really exciting opportunity, both for the environment and for creating more sustainable products and industries,” Mr Hasell said.

“Almost every household item has some kind of plastic polymer plastic in them and making polymers from sulfur, not carbon, opens doors into a new frontier of possibilities.”
