Drop in – The Zerma tyre recycling plant at which up to 45 tons of material are processed an hour is a substantial initiative, obviously, beginning with in-feed of tyre casings into a Zerma ZXS-T shredder for passenger car or truck tyres (up to 1500mm diameter) where material is reduced into strips and pieces of approx. 100 mm. The material then moves to a second-stage Zerma ZTTS shredder where it is reduced to approx. 20mm. Steel radial material is removed at this stage. Heavy-duty GSH granulators with a special closed H-rotor are used in the final stage, producing pieces down to less than 5mm or as required

Heavy-duty, high-efficiency Zerma technology for tyre recycling

10 FEB / MARCH 2019

With processing of scrap tyres, you either go huge or go home WITH the Supreme Court of Appeal’s recent ruling in favour of REDISA, the likelihood that the South African tyre recycling sector may be able to regain momentum has increased, meaning that tyre recycling may become a reality in the country. With that in mind, Jeff Cawcutt of Zerma Africa was an interested participant at Zerma’s global sales meeting in Thailand at which one of the Zerma customers in that country showed delegates its expanded tyre recycling plant. The Thai cement

manufacturer, one of the largest in South-East Asia, has expanded its tyre recycling plant from 25 to 45 tons per hour, which is substantial in anybody’s book. The name of the game for tyre recyclers – as it is for anyone involved in plastic or rubber recycling – is economy of scale: that is to achieve volume throughput where unit cost is as low as possible. With tyre recycling, tonnages are substantial and – in order for plants to operate profitably – high

efficiency technology needs to be utilised. Due to the increasing number of cars and trucks all over the world, used tyres are available in large quantities at relatively low cost, currently. With a bit of clever recycling, you can get a whole lot out of used tyres: granule in various sizes, steel and profit. The sales income naturally depends on the quality of the output material, and the process obviously needs to be as efficient as possible. >>

REDISA’s vindication & why it matters to you continued ... fight the case all the way to the SCA, it would have established a precedent whereby a solvent company can be put into liquidation on the say-so of a Minister with unfounded suspicions, a grudge, or some other arbitrary motive, without even the chance to defend itself. There are few businesses that can survive the process, since the directors immediately get cut off from their information and assets, and must contest the provisional liquidation from

their personal resources. And as we have seen in this case, that can mean fighting for two years without access to their livelihoods or business assets. The judgment was scathing both against the misuse and abuse of ex parte provisional liquidation applications, and the attempt to construe the Companies Act to allow a Minister to bring such applications. If this case had not been so decisively settled, any company in the country

could face the same attack, on equally spurious grounds, as REDISA. That would have been a serious blow to business confidence, at a time when we most desperately need to build, not break it. * Ex parte contact occurs when an attorney communicates with another party outside the presence of that party’s attorney. Ex parte contact also describes a judge who communicates with one party to a lawsuit to the exclusion of the other party or parties.
