Old tyres from motorists in the upper North Island will now be used as fuel for the Golden Bay Cement plant in Portland, Whangarei.
Fletcher Building completed an upgrade to its plant last month to allow it to use tyres as fuel, thanks to a $16 million grant from the Government's Waste Minimisation Fund.
Mahurangi-based Labour MP Marja Lubeck says the disposal of waste tyres has been an environmental headache in New Zealand for some years and the initiative will go a long way to reduce the tyre pollution problem.
Fletcher Building CEO Ross Taylor says up to half of the 6.3 million waste tyres produced in New Zealand will be used for cement manufacturing at the plant.
The tyres are combusted at around 1400C and any remaining particulates from rubber, metal or ash are combined into the cement.
It is expected to reduce carbon emissions by about 13,000 tonnes a year by reducing the need to use coal and iron sands as fuel.
Disposed tyres are collected from northern automotive garages and fleet managers and taken to Waste Management's tyre recycling facility in south Auckland.
The tyres are shredded into small pieces and then transported to Northland, where they can be used as fuel for producing cement.
