Latest offering from SRI boasting 100% Butyl Free SRI DVR Compound
Then when the same DVR Compound is added to Volume Medium grade Asian Retread Compound the results are interesting to say the least!The retention of properties is very exciting especially the EB% !!
With the significance of high Rolling Resistance and Heat Build Up in tyres being a direct measure of CO2 generation contributing to Global Warming its a particularly important factor in terms of sustainability in Commercial Vehicle and Passenger Car Tyres. The SRI DVR Compound is the first recycled content tested by global tyre manufacturers that does not impact adversely on Rebound Hysteresis test results which is a benchmark for Rolling Resistance and Heat Buildup in their tread compounds.
Groups sue U.S. EPA to close loophole, protect public health and the environment
June 16, 2011
Washington, D.C. —
Earthjustice, on behalf of Sierra Club, Montanans Against Toxic Burning, Huron Environmental Activist League and Downwinders at Risk filed a lawsuit in federal court today that challenges an egregious air pollution loophole supported by the U.S. Environmental Protection Agency. The suit disputes the Obama EPA’s unprecedented assertion that burning industrial solid waste as a fuel—akin to coal or natural gas—is a form of recycling, and therefore not subject to key provisions of the Clean Air Act that protect people from the harmful air emissions that result. Industry groups have pressed previous administrations long and hard for just such a favor, but the Obama administration is the first to acquiesce so broadly to their demands.
It did not come as a surprise when Sekhar Research Innovations (SRI) Sdn Bhd won the cleantech innovation award from the international technology consultancy firm Frost & Sullivan. SRI’s devulcanising process, which is a closed-loop rubber recycling solution that can match the volume requirements of rubber manufacturing, is not only an environment-friendly process but also holds out great commercial value.
SRI, founded by the doyen of modern rubber technology the late Tan Sri Dr BC Sekhar, is a renowned R&D firm working on ecological reuse of end-of-life tyres and waste rubber to produce premium tyres.
It won the Asia Pacific award in recognition of its technology’s uniqueness that will have a defining impact on new products, applications, functionality and customer value. The technology transforms the recycling of scrap rubber into a volume-based and industrially scalable process, said SRI CEO Gopinath B Sekhar in an interview.
“Our solution provides for substantial economies of scale by having a modular, high-volume processing system that lends itself to a very high-level of consistency in performance,” he said.
“Further, our energy footprint is lower than any other available devulcanisation technology and we have zero discharge.”
This is the first time that an eco-friendly technology will be able to match the sheer volume of tyre wastes generated in a way that is economically viable without relying on subsidies.
“Frost’s innovation award was a welcome validation of our efforts and achievements thus far,” Sekhar explained.
The product from SRI, which was a start-up based in the Malaysian city Petaling Jaya and is currently engaged in commercialising its process by opening a production facility in Malaysia, is a viable recycling solution that can address the problems of scrap tyres globally.
Sekhar said the world produces tyres in excess of 1 billion units yearly valued at more than US$130 billion. But scrapping them poses a major environmental hazard because it is difficult to dispose end-of-life tyres. It has been found that the option of producing tyre derived fuel by incinerating them is a global public health concern. More…..

TYRES. They are on our cars, buses, trucks and motorcycles. Yet, how many of us actually know what happens to them once they outlive their usefulness?
The issue of scrap tyre recycling is often placed down the pecking order after the primary worries of illegal logging, open burning and other forms of pollution. Granted, they may form only a small part of our lives but stacking these unwanted rings of rubber up into a pile will give a sense of what many nations are struggling to deal with – or get rid of.
Two industry organizations are objecting to a proposal by the Environmental Protection Agency (EPA) that would designate scrap tires as a “solid waste.” If the regulations are adopted, manufacturers that currently utilize tire-derived fuel (TDF) — such as cement kilns and paper mills — will have to operate under the tougher standards directed at commercial incinerators.
TDF-burning facilities would fall under more stringent Section 129 emissions regulations in the Clean Air Act, which would mean revamping or replacing current combustion units. The fear is that these firms would reject using TDF in favor of more traditional fuels — thus lessening demand for old tires. Read more
Moving aggressively forward in our work with tyre manufacturers in 2011. While we may be at varying stages of evaluation with several tyre manufacturers globally we are breaking into 2011 straight into tyre building trials with a major producer. This effectively means a fast forward in terms of our move to addressing the global scrap tyre problem while establishing the SRI Compound Masterbatch as a standard industrial raw material.
Devulcanized content in tires will not be about fillers and the proportions will be measured against total compound and not against raw rubber content, moving towards substantial volumes and huge strides in Cleantech. The market for fine powders will also see a major change as if they are able to maintain feedstock and purity they will suddenly become raw material of choice for devulcanization with their volumes taking a major increase with year round offtake and far less dependence on state subsidies.
The misconception that End of Life passenger car tires have no real value needs to be challenged and corrected. Today there are a few plants scattered around the world that crumb the material but it looks like the vast majority are incinerated as tire derived fuel (TDF). The approach to tire recycling thus far has been following the paths of least resistance with few technological strides of consequence. The primary problem in passenger car tires is the lower rubber recovery with a high fibre content,
The 12th of October 2010 was an interesting day, there we were signing our agreement with the MRB (Malaysian Rubber Board) at the same time as agreements were being signed with MARDEC and FELDA represented by their CEO’s. While it was nice to be operating on the same level as these enormous companies, it really augurs well for the planned collaboration with us as they are taking us seriously as a cleantech solution provider and a leader in tyre recycling/devulcanization. With this formal agreement which was hammered out with the support of their dynamic Director General, Dr. Salmiah Ahmad, the Rubber Board has effectively made a substantive commitment to support the development of recycling technologies. The agreement provides us with the requisite priority in using their equipment, provides for fast turnaround in testing and general collaboration in terms of applications.
