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.

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.

The 30th of July 2009, a very special day for me, one that I am unlikely to ever forget. We all have our ultimate goals and challenges in life, some spiritual while yet others take on mythic proportions to be striven for but more often than not, never achieved.

Green Tire before Moulding

Well I’ve been hunting my version of big game for some time now, in some ways a shared obsession with my father. For my father it was achievable, in his view it was just a matter of time, something just around the corner. After he left us, for me it became an elusive hydra, using it’s many heads to throw one impediment after another in my way. Strange how technology and chemistry can take on such colourful proportions but in this case getting there has been on par with finding “Big Foot” or the veritable doorway to Shanri-La.

Rubber Automotive Components – Recycled Content

photo by bitzcelt

Imagine having a car where all or most of its rubber based components are made with some order of recycled content. There are a few manufacturers who insist on a certain proportion of their components being “recyclable” but todate none have been able to actually meet the challenge of using recycling in all its OEM equipment other than by way of low grade fillers. I think it’s a very interesting challenge.

NR and Synthetic compounds from EPDM, NBR and Butyl are well represented in the more than 200 components made of rubber. Today all that has been done is introducing degraded material like reclaim in limited quantities playing to the very threshold of acceptable performance and performance. For the first time it will be possible to have recycled compound being introduced into the mix representing value addition.
