Israeli company announces de-vulcanisation process

ERJ staff report (DS)

Kiryat Gat, Israel -- An Israeli company -- Levgum -- claims to have developed a process for de-vulcanising rubber goods. The company says its technology is the brainchild of three scientists with wide experience in the rubber recycling and chemical fields.

The process is carried out by adding Levgum's proprietary modifier to vulcanized rubber brought into a stressed condition at a two-roll mill for about 20 passes. This mechanical-chemical process, accoriding to Levgum, "is carried out at room temperature, does not use harmful chemicals, does not produce or emit any hazardous waste or gases and is 100% environmentally safe."

Levgum aims to licence its technology to rubber companies. The process requires smooth rollers with a nip of around 0.1 mm (This seems very small, but is given on the company's website).
