Malaysian tyre recycling firm Green Rubber Global, whose shareholders include Hollywood stars Mel Gibson and Bruce Willis, is headed for a listing in London, a report said Tuesday.

Green Rubber plans to list on London's Alternative Investment Market (AIM) in six months, the Star newspaper said.

The Star said an official statement was expected to be announced at the Forbes Global CEO Conference in neighbouring Singapore later Tuesday.

It is unclear how much Green Rubber plans to raise in funds, but bankers are valuing the company at 150-170 million pounds (304-355 million dollars), the newspaper cited an industry source as saying.

Other shareholders in Green Rubber are Malaysian businessman Vinod Sekhar, Indian former cricketer Kapil Dev, former golfer Lee Westwood, the Forbes publishing family and the former chairman of Britain's Vaux Brewery, Paul Nicholson.

Sekhar owns 84 percent of Green Rubber via Petra Trust, while the remaining 16 percent is held by his celebrity friends.

Green Rubber's first tyre recycling plant is in Gallup, near Albuquerque in New Mexico.

The process, which avoids used tyres being burned or ending up as landfill, reportedly uses waste-free environment-friendly technology to produce a rubber compound that can be used to make a variety of products including tyres.
