While the potential risks associated with the use of crumb rubber in synthetic turf, have been debunked by over 90 separate pieces of research, the issue “is not going away” until “a definitive study” is published, according to Robin Wiener, President of the US Institute of Scrap Recycling Industries (ISRI).
Speaking at recent the Bureau of International Recycling (BIR) World Recycling Convention & Exhibition in Hong Kong, she said that despite the impressive body of research, negative media reports surrounding crumb rubber use in artificial turf have prompted some US jurisdictions to delay purchasing decisions while 13 bills have emerged in the US this year targeting this application.
The “cloud of uncertainty” had led to a 30% decline in the crumb rubber market over recent years and also to job losses, Wiener told the BIR Tyres & Rubber Committee meeting in Hong Kong.
She warned that this represented “an industry-wide issue affecting all recyclers, regardless of commodity” and that it was therefore essential to “work together, sharing information and strategies”.
Wiener also pointed delegates in the direction of the RecycledRubberFacts.org microsite which carries information on “all the various studies out there that have demonstrated the safety of this material”.BIR Tyres & Rubber Committee chairman, Barend Ten Bruggencate of Recybem in the Netherlands noted that both the Dutch public health and environment institute RIVM and the European chemicals agency ECHA have both insisted recently that the health risks associated with rubber granulate were “negligible”
He also highlighted statistics from the European Tyre and Rubber Manufacturers’ Association indicating that 95% of the EU-28’s used tyres underwent some form of treatment in 2015 - including material and energy recovery - whereas only 5% or 186,000 tonnes was landfilled.
In China, the most recent figures available suggest regenerated rubber production accounts for 36.5% of waste rubber utilisation while vulcanised rubber powder production and thermal cracking contribute a further 5% and 3.6%, respectively. Tyre retreading consumes 4% and has been “stagnant” in China over recent years
The Hong Kong meeting was informed by Qiang Yu, Executive Chairman of the China National Tyre Recycling Association and President of Tianjin Hi-tech Environmental Development Co. Ltd.
The speaker also noted that his company had paved more than 4100km of highway using tyre-derived crumb rubber modified bitumen.
Waste Agricultural Tyre Recycling Success in Maryland

$6.9m Tyre Recycling Facility Coming to Anderson County, South Carolina
Columbia, South Carolina based tyre recycler and rubber manufacturer, Viva Recycling of South Carolina, is to establish a new facility in Anderson County.
Co-operation Between Tyre Recyclers and Manufacturers Needed
Increased co-operation between recyclers and tyre producers is needed to solve the short-, medium- and long-term problems endangering a sound economic environment for the tyre recycling industry, was a the consensus at a round table discussion at the Bureau of International Recycling Convention in Prague.
