Penalty Accusations on Crumb Rubber

Producers of crumb rubber used in sports field turf applications are facing accusations that the material is causing health problems. Using crumb rubber as a “shock absorber” on artificial turf playing fields has been one of the fastest growing markets involving crumb rubber over the past two decades. Although using the material has been largely successful both for crumb rubber producers and for synthetic turf fields installers, some of the athletes who play on the fields and their parents have made some serious accusations regarding the effects of crumb rubber on public health. Since 2014 both victims and parents have searched for connections between the crumb rubber used in some fields and forms of cancers developed in young athletes. The increased media exposure of the topic led to its inclusion on the agenda of the ISRI 2015 Convention & Exposition in April in Vancouver. According to speakers at the convention, a theory formulated by the University of Washington women’s soccer coach Amy Griffin, suspects that there are linkages between the crumb rubber used in the playing fields and lymphoma – a type of blood cell cancer. However, a report from NBC News (can be found at has stated that there has been no research linking artificial turf to any type of cancer. NBC News has further elaborated in their report, that neither any relevant studies, nor interviews with...

Weibold! Academy: Rubber Powder Applications – Rubber Industry

Dear Readers, This is the sixth article from our monthly blog series “Weibold! Academy”. As we have mentioned before, with these articles we try to provide our readers and our newsletter subscribers with valuable knowledge about the tire recycling industry. We believe that a good knowledge foundation might be beneficial for everyone involved in the industry and each month we cover different topics, thus providing you with important know-how for the tire recycling industry. Month by month we together dwell deeper into the world of tires and the ways of recycling them. In case you have missed our first five W! Academy articles, you can find them here: Welcome to Weibold! Academy Weibold! Academy: Recycled Rubber Output Spectrum and Rubber Granulates Weibold! Academy: Rubber Granulates, Rubber Powder, Tire Derived Steel and Tire Derived Fiber Weibold! Academy: Tyre Recycling Value Chain Weibold! Academy: Applications for Tyre Recycling Plant Output Weibold! Academy: Rubber Granulate Applications This month we continue covering the recycled rubber output spectrum. We will start explaining about rubber powder applications and in particular about the Rubber Industry. Rubber Powder Applications Rubber Industry Sales markets for fine rubber powders in the rubber processing industry ensue with the application of rubber powders as fillers and substitutes. Rubber powder can partly surrogate cost-intensive raw materials like natural caoutchouc. The situation for synthetic stirene-butadiene rubber (SBR), also substitutable by rubber powder is quite similar....

Ensure Your Successful Grant Application with Weibold! – Programmes in South Africa for the Manufacturing Sector

  The Department of Trade and Industry (the dti) of South Africa is currently offering two grant programs to the manufacturing sector – the Manufacturing Competitiveness Enhancement Programme (MCEP) and the Capital Projects Feasibility Programme (CPFP). Weibold! can help interested businesses and private investors by developing the pre-feasibility or the feasibility studies required for a successful application.   Manufacturing Competitiveness Enhancement Programme (MCEP) The objective of the programme is to facilitate feasibility studies that are likely to lead to bankable business/project plans, which will result in investment in new components or products or processes not currently manufactured or performed by the applicant or in the creation of markets that will lead to a substantial increase in the manufactured products of the applicant. The expected investment project to result from the feasibility study should have a minimum value of R30 million. The feasibility study component of MCEP offers a cost-sharing grant of 50% or 70% of the cost of the feasibility study, to be payable according to expected milestones. The cost-sharing grant percentage will be differentiated by enterprise size as follows: Applicants with total assets with a historical cost below R30 million may qualify for a grant of 70% of the cost of the feasibility study; and Applicants with total assets with a historical cost of at least R30 million may qualify for a grant of 50% of the cost...

New material in trackbed sub-ballast using rubber from used tyres

  A new material has been developed for usage on train tracks as subballast layer and it incorporates rubber shreds from old tires. The mixture is a combination with crushed stone and it has already been applied with great effect in roadside embankments and asphalt mixtures. Its usage in the rail sector, however, is yet to be explored. UPV technicians have already assessed the new material with tests along a section of the Almoraima-Algeciras ADIF line in Andalusia. Along with offering an outlet for recycling old tires, it has also shown some serious advantages when compared to traditional materials. For example, it provides good insulation for urban environments in close proximity to rail traffic, since it absorbs vibrations from passing trains. Also it offers higher resistance to abrasion and fragmentation of the crushed stone due to the addition of tire rubber in the mix. Researcher at the university’s Institute of Transport and Territory (ITRAT) Pablo Martínez Fernández has explained: “There are multiple benefits to using this material. On the one side, it contributes to mitigating the vibrations caused by moving trains. But at the same time it opens up a new market for many of our quarries, particularly limestone quarries, as well as for tyre recycling companies. It revitalises both sectors, making better use of the available limestone, not normally fit for use as a sub-ballast because of its...

TreadWright Presents New Tire with a 70-Percent-Recycled Content

The Houston-based tire company TreadWright has released new Claw II MT Series Tires geared toward the off-road market. The new tires for mud terrain combine the company’s green manufacturing process with a special mud-terrain tread pattern, which delivers greater performance on many of the more difficult off-road terrain. The TreadWright tires are manufactured with 70-percent-recycled content, including the premium brand tire structures. By using remolding, the company applies full-grade truck rubber to its tire structure, resulting in the Claw II tires achieving the same mileage as most premium original equipment, light truck and SUV tires. Moreover, each Claw II MT series tire is produced using 65 percent less oil than standard tires. “This is our most aggressive and rugged mud terrain tire yet,” said Anthony Showen, TreadWright’s CEO. “Our new Claw II series delivers great performance and value and we’re also proud of the Claw II’s environmentally friendly manufacturing process, which may be the greenest in the US.” Article source: Recycling Today...
