So far this year, 247.7 tons of rubber crumb have been exported to A1 Rubber, an Australian company.
OTML superintendent Waste Treatment and Disposal, Hendrick Min, said this year OTML expects to produce 720 tons of rubber crumb.
"We are capable of producing 5.7 to 7.6 tonnes a day if we have more buyers.
"We only have one buyer at the moment, so we are producing at this current level," Mr Min said.
"Our ultimate aim is to reduce OTML’s footprint and that has been our driving force," he said.
Mr Min added that OTML has about three to four year’s stock of old tyres, which is significant enough to meet additional demands for rubber crumb.
In 2013, OTML commissioned a rubber recycling plant in Tabubil as part of its waste management strategy, to recycle old conveyor belts, and tyres from its mine haul trucks and other vehicles.
