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.

Scrap Tires - Solid Waste Managment

The ultimate model which addresses all possible aspects of environmental sustainability in rubber recycling is still Devulcanization but should start right from the collection of tires. This means the starting point should be at the tire collection centers or in the US possibly at the landfills. Here we are not talking about solid waste management anymore but effectively managing a vital raw material in process.

Addressed properly the tires would not be dumped in the open but would be separated out between passenger car and commercial vehicle (truck) tires, making it possible to split up the feedstock into types ie. Mostly Natural Rubber (80/20) from Commercial vehicle tires and Mostly Synthetic (60/40) for passenger car tires. This important step also makes it possible to shoe horn in a step which could see the eventual removal of the Butyl inner liners by grinding or peeling off. The resultant by-products would be butyl scrap feedstock and butyl free scrap tire feedstock, an interesting and very significant change to the current situation.

RUBBER ASIA MARCH – APRIL  2011

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…..

Turn old tyres into new ones

By GEOFFREY YEOW
star2green@thestar.com.my

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

SRI on Discovery News

The smell of a burning tire is unforgettably putrid, but so far recycling technology has been unable to resurrect dead wheels. Millions and millions get discarded every year. Now a Malaysian startup says they have an answer. 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.
