Tyre Stewardship Australia has provided funds to the University of South Australia to conduct research and testing of advanced formula of Crumbed Rubber Concrete (CRC) intended to be used in residential building projects. CRC relies on crumb rubber that is used as partial replacement material to sand in mixtures. Present studies have shown that CRC had absolutely identical performance as traditional concrete in residential construction, and no visual flaws were reported after 3 months.

The K show in Germany city of Düsseldorf set October 16-23 will see Evonik Industries AG exhibit its patented rubber additive, Vestenamer, that allows transforming waste tires into products that can be applied to construct roads. The company’s additive makes the process of transforming waste tires into rubber powder that can be used in asphalt cost-efficient; this Evonik’s innovation is used in combination with road construction asphalt as it can improve the quality, thus extending the life of roads and boosting their durability preventing wearing off.

A global producer of synthetic rubber Trinseo believes that styrene which can be processed out of plastic waste can be reused in tire manufacturing; however, it is still unclear how the industry could switch from a linear production reaching a more sustainable approach like circular economy. This concern was voiced by Trinseo’s tech and innovation director Sandra Hofmann during Future Tire Conference 2019 in Germany’s Cologne earlier this month. She explained that currently there is an access to a stream of recycled styrene that could be used in packaging, or, alternatively, be upcycled in tires and SSBR (solution-styrene butadiene rubber).

Italy-based EcoTyre shared its first results of devlucanization initiative saying that the process gave outstanding results when used on retreaded Hankook tires. Some materials that rely on devulcanized rubber were used in tire retreads; according to EcoTyre, this method brought positive outcomes of the testing and the company now seeks to apply more devulcanized rubber in retreads as well as in new tires.

Cement company Argos belonging to a larger Colombian conglomerate used over 75,000 tons of waste as energy source last year – this amount represents all waste, including scrap tires, that a city with population of 200,000 generates annually. Moreover, the company’s alternative fuel control system at cement plant in Cartagena uses scrap tires and helped increase co-processing capacity of Regional Colombia by 200%. Following the success, the company signed an official document in which it set forth its commitment to sustainability vowing to rely on alternative fuels, including scrap tire rubber, received via recycling.

On November 11-15 this year, one of the most industrialized cities of Mexico, Queretaro, is hosting the XV Latin American Conference on Rubber Technology that will also shed light on future and potential developments in tire recycling in North and South America. It is anticipated that the event will unite representatives of public sector and businesses; thus, it will become a sound platform for networking where visitors could offer their services and products. According to the event’s website, the biggest companies representing the recycling sector will attend the conference.

A British company Rosehill Security will start providing its security molded goods from recycled tires, including hostile vehicle mitigation (HVM) barriers, Ballistic Blocks and Rapid and Impakt Defenders to the US market after it signed a deal with ARX Perimeters (ARX). The production of Rapid and Impakt Defenders relies on recycled tire rubber, and uses polyurethane to get extra strength. The product can be used in almost all types of surfaces, ranging from roads to stadiums. It is also possible to apply them in combination with mobile perimeter and high-security fence systems – this would secure boosted protection.

Equine Air, a product developed after Tyre Stewardship Australia (TSA) teamed up with Flexiroc, was used for a trial on 550 square meters of Pakenham Racing Club Tynong race track in 2018. The findings of the experiment with the trail were positive, and the riders admitted the benefits of the new surfacing. To manufacture the product, developers used more than 3,000 tires – this equals 27 tons of recycled rubber. It has an innovative design enabling the product to be used for difficult ground conditions. Moreover, it helps the surface to drain quickly following rain.

Using electronic identification chips in new tires has been found to be an efficient practice that tire producers can undertake. The verdict about its technical feasibility was delivered by the National Highway Traffic Safety Administration (NHTSA). However, the group also noted that the technology has to be standardized, and this means, the industry will have to elaborate on it, as well as new regulations will be required.
