The Recycling and Economic Development Initiative of South Africa (Redisa) says waste tyre remediation company Waste Beneficiation, which is supported through the initiative’s business incubation programme, is ready to use its waste tyre shredding solutions to implement tyre abatement plans for waste off-the-road (OTR) tyres for the mining industry.

Part of Redisa’s mandate is to develop independent businesses that will compete in local and international markets, says Redisa director Stacey Davidson, explaining that the programme aims to prove the viability of businesses in the recycling industry, as well as create and develop entrepreneurs in the industry.

“Redisa has an obligation to create a waste tyre recycling industry, which means the initiative also needs to investigate recycling capability requirements and technologies for the remediation of waste tyres that are generated by the mining industry,” she stresses.

Davidson notes that, while mining companies are required by law to have waste tyre stockpile abatement plans in place to deal with large waste OTR tyres, there is no solution to deal with the problem – either through downsizing or recycling – and only a few mining companies have met the compliance requirements.

“Waste Beneficiation, however, has acquired Eagle Plant machinery that can downsize from between 50 t/d and 60 t/d of waste OTR tyres using state-of-the-art machinery,” she says.

The mobile plant, currently located at premises in Wadeville, Gauteng, was commissioned this month. The company currently employs nine people at the plant, but aims to increase this number to 16 by the end of the month.

Meanwhile, to raise awareness of Waste Beneficiation’s assistance to mining companies in implementing their waste OTR tyre abatement plans, the company highlighted its service offering at this year’s Investing in African Mining Indaba, which ran from February 8 to 11 at the Cape Town International Convention Centre.

The offering includes the Eagle Plant equipment, which comprises the Titan II cutter, as well as a tyre handler, debeader, punch cutter, grabber, shredder and skid loader, collectively valued at R35-million.

Waste Beneficiation CEO Khothatso Moloi highlights the significance of the OTR problem, claiming that, until now, the necessary technology and machinery have not been available in the country to deal with it.

The end product downsized by Waste Beneficiation’s machinery is shredded, high-quality OTR rubber: “The technology enables Waste Beneficiation to adjust the size of the shredded rubber based on the requirements of the recycling company purchasing the product.”

Once the product has been downsized by Waste Beneficiation and then by the recycling companies, the shredded product can be used in asphalt, as well as the manufacture of roofing tiles, rubber bricks and matting used at playgrounds.

Davidson says, while Waste Beneficiation’s plant currently shreds new waste tyres, Redisa aims to also remediate the historical stockpiles, which comprise waste OTR tyres that were manufactured before Redisa’s Integrated Industry Waste Tyre Management Plan came into effect in 2013.

In terms of the Redisa plan, OTR tyres, or category 4, 6, 7, 8 and 9 tyres, are to be dealt with no later than 18 months after publication of the plan, which was gazetted in November 2012. Therefore, Redisa has to start collecting these tyres by May 2014.

Davidson notes that the first collections took place in Mpumulanga. For the year ended November 2014, of the 56 436 t of waste tyres remediated, 991 t were OTR tyres.
