TIA & RMA Proposed EPA Restrictions on Burning Tyres as Fuel

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

Sustainability with Performance & Value Added Rubber Recycling – SRI Tyre Building Trials in 2011

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.

Scrap Passenger Car Tires & Tire Derived Fuel

Incineration as Tire Derived Fuel

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,

Agreement & Collaboration with the Malaysian Rubber Board on SRI Rubber Recycling Technology

Signing Agreement with Dr. Salmiah Ahmad, Director General of the Malaysian Rubber Board

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.

Green Car Project Ready for 2010

A Labour of Love

The idea was to take a classic performance car, bring it back to optimum condition, if not slightly better and then change all the rubber components in it to ones with substantial recycled content in the form of my SRI Activated Compounds. Targeting more than potentially 200 components, no fillers or diluents but substitution of one compound for another in proportions ranging from 5% to 30% plus, subject to the application and required performance parameters. The final product performance exhibiting no appreciable loss off properties or performance. The car may be a classic but its performance specs at every level require high performance rubber components and by extension sophisticated compounds even by today’s standards, so whatever works here is equal to anything on the road anywhere.

Rubber Recycling – The World Needs A Real Solution

crumbrubber A few days ago I saw an interesting article about a big rubber scrap (tire) rubber recycling operation being set up in Houston. Actually what was interesting was the way in which they justified the process and it’s viability, they were trying to compare the production of crumb as a superior recycling solution to the retreading of tires. The point I am making is that when you have been floating in a void long enough you forget where you come from and where your going becomes a function of the direction you happen to be pointed in. Now it sounds like a desperate attempt to find a positive spin to defend the indefensible where the audience has forgotten the plot, so no worries.

14% Recycled Content and Being Evaluated as Virgin Compound!

With SRI Test Light Truck ready for tire measurements at RRI Tire Lab

21st of October 2009 another historic day, light truck tires produced using my activated compound (Magnum SRI custom compound) establishing a 14% recycled content and ensuring the manufacturer a 6% to 8% savings in raw material cost. After having run the tires successfully through several lifetimes (30,000km), official on road measurement and validation trials started today using our tires installed on a light truck  under the supervision and protocol of the Rubber Research Institute. We will be reporting the results of the evaluations as they come out, obviously we are expecting the results to be quite exciting and reflective of the laboratory test results.

Recycled vs Recyclability & Automotive Components

For some time now there has been a concerted move in Europe especially among the major manufacturers to ensure that a large proportion of their cars and manufactured with automotive components that lend themselves to be easily recyclable. This doesn’t mean that they are not using new virgin material or that the environment will not be damaged in their manufacture, it means that impact subsequent to their use and scrapping will be mitigated as these components may be more readily recycled into other material

Working on Processing and Conversion of Skim Block and Coagulum Scrap into Engineering Grade Rubbers

Rather than the dilution of quality a far better and more interesting approach would be to mechano chemically process it into a value added raw material, possibly deproteinized engineering rubbers.

This would be of particular commercial significance to Latex centrifuging and Latex Foam operations where I believe there will be a appreciable benefit in terms of their bottom line. Your also taking a throw away material that actually puts a strain on latex effluent treatment and converting it into a very useful value added raw material that will have a demand in the manufacturing sector. Imagine using this material as a substitute for supplementary rubber content where required.
