National roads being upgraded using recycled truck tyres
The use of large amounts of recycled rubber crumb for the manufacture of road surfaces and related products is propelling South Africa towards a circular economy where waste products are usefully used to address key infrastructure needs, Dr Mehran Zarrebini, CEO of Hammarsdale-based radial truck tyre recycler, Mathe Group, points out.
Much of the production from Mathe Group factory, which recycles approximately 1 000 radial truck tyres per day to produce 45 tons of rubber crumb, goes to bitumen product manufacturer, Tosas, for the manufacture of rubber modified bitumen, a product that is being used by the South Africa National Road Agency (SANRAL) for massive upgrades to the N1 in Gauteng and the N2 / N3 leading from the port of Durban.
