We 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.
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.”
Three Japanese firms are jointly conducting pilot testing that involves joining data gained from an internet-capable tyre with a road surface sensing system to map data. The trio – tyre maker The Yokohama Rubber Co., Ltd.; map and navigation technology specialist Zenrin Co., Ltd.; and technology company Alps Alpine Co., Ltd. – have now also begun studying ways to monetise this technology.
Test specialist Horiba Mira expects the new ‘rules of origin’ clause will drive a surge in demand for development and testing of EV battery packs.
It comes as last month Aston Martin boss and Nissan planning chief Dr Andy Palmer issued a warning to the UK government that the Brexit trade deal, alongside ambitious plans to ban the sale of new petrol and diesel cars by 2030, presents a risk of “crippling tariffs” for the UK automotive industry unless the sector invests heavily in domestic battery production for electric vehicles.
Billed as “the first complete simulation platform that cuts time and costs in the development and testing phases of both tyres and vehicles”, MegaRide has launched the RIDEsuite tyre simulation platform road and motorsport applications. Boasting performance enhancements of up to 30 per cent, RIDEsuite is described as a modular and multi-physical platform consisting of four applications.
We’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.
The 40th annual Tire Society Conference on Tire Science and Technology will again be held virtually this year, from 30 August to 3 September 2021. This year’s theme is “The Virtual Tire” and many conference papers each year are chosen for publication in the critically reviewed Journal of Tire Science and Technology, published quarterly by The Tire Society.
As part of a range of structural changes taking effect on 1 April, Toyo Tires will draw upon its experiences making tyres for the demanding European market in order to benefit its development programme for other regions. The tyre maker is integrating its Europe/Module Development department, which currently operates under the Technology Development division within its R&D Headquarters, into the R&D Headquarters’ Replacement Tire Development department.
In December 2020 French group UTAC CERAM announced that it was buying British test specialists Millbrook, which also owns well-known tyre test centres such as Test World in Finland. The plan is to merge the two companies, creating “a market-leading group in vehicle testing, vehicle type approval and emerging technologies for autonomous, connected and electric vehicles”.
AB Dynamics is showcasing its ability to replicate simulated swarm tests quickly and accurately in the real world and vice-versa. According to the company, this work enables the testing and development of ADAS and autonomous systems to be significantly accelerated whilst also reducing risk and cost.
Qingdao Sentury Tire Co., Ltd. has appointed Martin Winter as global technical director OE. Winter has more than 20 years’ experience of working in original equipment tyre development with Continental, Goodyear, and most recently Hankook. Sentury Tire states that Winter will work to establish relationships with leading original equipment manufacturers. Sentury is seeking to “establish and increase a competitive partnership and relationship” with European and global light vehicle makers. Manufacturing from its base in Qingdao, China and in Thailand, Sentury is primarily known for its Landsail brand in the UK and Europe.
Davanti Tyres is opening a European Development Centre at Applus+ IDIADA. The brand, owned by the UK’s Oak Group, says the centre will “spearhead its next-generation tyre design.” Davanti has previously used the Spanish facility, located in the northeast of the country near Barcelona, in the development of its tyres. It says the facility will allow its research and development team to experiment more with innovative new designs and materials, speed up new product development, and enhance ongoing testing and improvement of its existing range. General manager Peter Cross calls the move “the biggest step Davanti has taken since we brought our first tyre – the DX390 – to market.”
South Korea’s Ministry of Science and Information & Communications Technology has given Hankook Tire and its Hankook Technodome R&D centre its ‘Certification of Exemplary Laboratories in Safety Management’, a distinction given to laboratories that have passed an expert assessment by leading professionals. Hankook comments that this is the first time a tyre company has received this certification in Korea.
Analysis of the latest data from the Office of National Statistics by R&D tax relief specialists Catax shows that R&D spending in the UK motor industry has slumped 9 per cent annually. Total motor sector spending on R&D fell to £3.42bn last year, a decrease of £338m from a record high of £3.75bn registered a year earlier. The industry now employs 22,000 people directly involved in R&D, however, the latest spending figure is a dramatic turnaround from the 4.2 per cent increase seen in 2018.
