RECYCLING
Recycling strategy needed for construction industry IMS Engineering believes that it is time there was a coherent strategy for construction and demolition (C&D) waste recycling in South Africa.

OUTH AFRICA needs to follow many European countries which have established well-organised, highly efficient recycling processes. This is the view of Shannon McEwan from IMS Engineering. “This would make a significant contribution to the quality of the environment while producing significant direct financial savings, not to mention business opportunities and jobs,” says McEwan He adds that one of the foundations of a successful recycling strategy is appropriate, fit-for-purpose machines for the job. “In essence this means machines that accept the right feed with a minimum of prepreparation, and produce clean separated saleable products in the fewest appropriate, economic steps.” “Companies are beginning to realise that, with the right technology and processes, they can unlock significant value from waste materials. In the construction industry this includes construction waste and demolition material in the form of rubble, concrete, steel reinforced concrete and asphalt. When one takes into account the rising costs
of all building materials, rising dumping costs, the increase in the fuel price and the negative environmental impact of dumping unprocessed C&D waste, it makes sense to re-use what useful construction materials you can, or to benefit from income derived from the sale of the recycled material such as clean G5 filler, or selling recovered steel reinforcing to another recycler, instead of simply trucking loads of discarded building material to landfill sites.” To this end, IMS Engineering, as a subsidiary of Hazemag and EPR GmbH, Germany, has geared itself to provide a broad spectrum of recycling solutions to the construction and recycling industries including its range of Hazemag horizontal shaft impact crushers and MinPro horizontal impact roll crushers . Hazemag is the world leader in rubble recycling crushing technology. It produces robust and effective crushing plants ideal for the crushing of demolition rubble and concrete debris – including steel-reinforced
concrete, from which “cleaned” steel is effectively liberated – as well as broken road paving, asphalt, railway sleepers and blocks.
