Australian researchers develop new recyclable "rubber"

Australia’s Flinders University have now reported a new chemical that can make rubber meld seamlessly back together and better yet, the material is made of waste products and can easily be recycled itself.

Rubber can be recyclable with the new material

The new material is made up of more than 50% sulphur, mixed with some canola cooking oil and a chemical compound called dicyclopentadiene (DCPD). This unusual concoction makes a new form of sustainable rubber. These are the three main ingredients to make the rubber which has a bonus of all of them being industrial waste products. For example, DCPD is a by-product of petroleum refining which means its cheap and environmentally friendly to produce the new material.

The new rubber can completely heal itself in minutes after exposure to amine catalyst.
 
“This study reveals a new concept in the repair, adhesion and recycling of sustainable rubber,” says Justin Chalker, lead researcher on the study.
