Does the hyper-elasticity of retreaded tyres impact their behavioural quality? Uday Gudsoorkar and Rupa Bindu, two researchers working within the department of mechanical engineering at the Dr DY Patil Institute of Technology in Pune, India sought to answer this question and more by using computer-aided finite element analysis. Their paper “Computer simulation of hyper elastic re-treaded tire rubber with ABAQUS”, which was published in November 2020 in Materials Today: Proceedings used a combination of qualitative and quantitative methodologies to measures forces across the tread belt in a compute simulation. These virtual samples were then compared with laboratory examples. According to the paper, the researchers’ findings are “promising to predict the behaviour of re-treaded tyre rubber” and can be “used to improve the product [retreaded truck tyres] and its utility in small tyre re-treaders, customers and policymakers.”

SSH Recycling Ltd has submitted a planning pre-application to Renfrewshire council in a bid to build a tyre devulcanization and processing plant in Linwood, Renfrewshire, Scotland.
The project is what the company describes as “the first of its kind in the UK” and is intended to “solve the entirety of Scotland’s waste tyre problem, using revolutionary new technology to recycle or reuse every component part of the tyre”. However, SSH’s process will support the devulcanisation of treated rubber in order to create synthetic rubber sheet, conveyor belts, shoe soles or rubber mats.
Vipal Rubber is researching the possibility of using rice husk residue as a raw material for the rubber industry, the result of a partnership between Vipal, the University of Caxias do Sul, in Brazil, and Lodz Poland University of Technology. Goodyear released a rice husk silica tyre in China in mid-2015, before announcing in November 2020 that is would double its rice husk usage by 2021; and Pirelli announced that it was researching the use of rice husk ash in new tyre compounds back in April 2009; but Vipal is the first retreading compound maker to go public with its use of rice husks in compounding.
B&J Rocket is offering retreaders the opportunity to earn reward points with every purchase of B&J products throughout the year.
