Falken: Power generation tech measures tyre wear
A joint project between Sumitomo Rubber Industries, parent company of Falken Tyre Europe, and Professor Hiroshi Tani of Japan’s Kansai University has resulted in the development of an innovative power generator for tyres. It generates electricity from the rotation of the tyre and uses this to power peripheral sensors installed within the tyre. In this way, the sensors can operate without the need for batteries.
SRI: Better tyre rubber through tomato research
Tyres and tomatoes. At first glance these have little in common apart from the same initial letter, but Sumitomo Rubber Industries, Ltd. may beg to differ. The Japanese manufacturer shares news of joint research work focusing on an enzyme that is found in tomatoes and has a similar structure to those involved in the biosynthesis of natural rubber.
Pirelli extends tyre tech research partnership
A decade after the first agreement, Pirelli, Milan Polytechnic and Polytechnic Foundation have signed off a three-year continuation of their ‘Joint Labs’ programme, which centres upon research projects that advance tyre-related technological innovation.
USTMA producing standardised tyre tread particles to advance scientific research
The U.S. Tire Manufacturers Association (USTMA) intends to produce cryogenically milled tyre tread (CMTT) and provide samples to researchers in order to advance scientific study on tyre and road wear particles (TRWP). Representatives from the industry have presented information about this initiative at the 42nd Annual Meeting of the Society for Environmental Toxicology and Chemistry (SETAC) North America, a virtual meeting that’s taken place between 14 and 18 November.
Michelin: SimatLab speeding up development
The SimatLab public-private research laboratory, created in 2017 by the Michelin Group and the Clermont-Ferrand Chemical institute (ICCF), is renewing its works on modelling future materials for another four years. Furthermore, the laboratory is speeding up its development by integrating new partners and widening its areas of research to the medical and hydrogen fields.
Insa Turbo researching solvent-free retread adhesion
Ellie BurginInsa Turbo is embarking on research into the “…development of a new rubber-rubber adhesion system for the reuse of end-of-life tyres” in order to improve its products and make them “even more sustainable”.
Global retreaded tyre sales to hit $8.8 billion in 2021
C Technical; PexelsGlobal retreaded tyre sales are expected to reach US$ 8.8 billion in 2021, according to research produced by ESOMAR-certified market research and consulting firm Future Market Insights. According to the new report entitled “Retread Tires Market”, the increase in average miles driven and growing vehicle parc will drive the tyre aftermarket, subsequently fuelling the demand for retreaded tyres.

Master’s thesis rates circular economy methods for recycling end-of-life tyres
BlackDonutsIn addition to the flurry of research relating to tyre pyrolysis published at the end of 2020 and the start of this year, in February it emerged that another related study has been released. In his master’s thesis for Tampere University, Mikko Sirén explored the best technologies for turning scrap tyres into secondary raw material and value-added products. The research project started in May 2020 as an initiative of Black Donuts, the turn-key tyre industry consultants, who desired up-to-date research of the recycling of discarded tyres as part of their circular economy initiatives.
Cooking up better tyre pyrolysis oil compounds
“Wastes to energy: Improving the poor properties of waste tire pyrolysis oil with waste cooking oil methyl ester and waste fusel alcohol – A detailed assessment on the combustion, emission, and performance characteristics of a CI engine”, published in the journal Energy on 22 January 2021; and “Thermodynamic comparison of pyrolysis and gasification of waste tyres”, which was published in the Journal of Environment Chemical Engineering on 30 January 2021 complete our recent review of the latest peer-reviewed pyrolysis research.
Spike in tyre pyrolysis investment backed by flurry of related scientific research
Scott Donkin – stock.adobe.comWe have all witnessed the recent spike in interest in tyre pyrolysis-related recycling during the last year or so. The concepts themselves are not new, so what is behind renewed interest and confidence in such projects? As well as an uptick in investment in tyre pyrolysis plants, the last few months have also seen the publication of a flurry of peer-reviewed research papers into different aspects of waste tyre pyrolysis. As part of this year’s annual Tyre Recycling feature, we took a look at the three most recent papers in order to find out more.
Research: Retreads offer hyperelastic tyre characteristics
Ivan; PexelsDoes 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.”
Recycled tyres used in new strengthened concrete
RMITWe’ve all heard of tyre-derived oil and rubberised tarmac, but what about tyre-utilising concrete? Australian researchers have developed a new technology to manufacture concrete made from recycled materials including tyres that is stronger and more durable than the traditional product.
Tyre particulate solution wins James Dyson Award
The Tyre CollectiveThe Tyre Collective – winners of the James Dyson Awards 2020 – have designed a device to capture tyre particulate at source. According to the UK Department for Environment, Food & Rural Affairs’ “Air Quality: Brake, Tyre and Road Surface Wear” report, tyre-wear accounts for nearly half of road transport particulate emissions. Furthermore, a reported half a million tonnes of tyre particles are produced annually in Europe alone, from vehicles accelerating, braking and cornering. As we move towards electric vehicles in the future, exhaust emissions will reduce but tyre particles will continue. The Tyre Collective estimate that tyre emissions may even increase, as electric vehicles become heavier due to the added battery weight. For both reasons, this year’s UK national James Dyson Award winners attempt to address this issue.
2020 Tire Society meeting goes virtual, theme: intelligent transportation
The 39th Tire Society Conference on tyre science and technology, which runs from 28 September to 2 October, will be held entirely
virtually for the first time this year, due to the Covid pandemic. However, it will still feature 27 original works of tyre technology presented by the authors and a special topic paper on the 40+ year history of the Tire Society as well as a keynote address, plenary address, invited lecture and panel discussion.
