Recycled and devulcanized rubber

Sustainability Aspects: Till recently vulcanized rubber like used in car tyres couldn't be recycled. Thus every year about 1.3 billion tyres, mostly form Europe and the US ended up either in landfills or were burned. The Petra company developed a technology with which they can d

The devulcanized rubber

Rubber manufacturers typically throw off waste of 5 to 15 percent – it’s a cost of doing business. These manufacturers now have another, more profitable option. They can recover this waste and crumb it into granules of rubber. They can then mix two parts of DeLink to 100 parts of the crumbed rubber. As a result, they create a de-vulcanized rubber compound, which can be reintroduced into the manufacturing process. The company ends up with two benefits. It is waste free and the waste cost is eliminated. Plus, the new compound, created from the waste, costs far less than purchasing virgin rubber compound on the open market. Numerous companies in Malaysia, Thailand and China are successfully using this process today.

The cost, compared with virgin rubber compound, will be a significantly lower. These companies would also have the option of entering into a licensing agreement whereby they can use the Green Rubber name and logo. There will be quality standards and marketing support, likely they can get a higher price for their products because of their “greeness”.

The product spec of the DeLink chemical mix provides no details about it composition so how green is green? They received the ‘global green USA’-award which hopefully tested it. But getting rid of 1.3 billion tyres of waste is a big improvement!
