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.

Innovation

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

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.

Corn Starch & Latex Protein

Photo by AMagill

It is really unfortunate that the corn starch used in conventional examination gloves has been so demonized by its tenuous link to latex protein allergy that I fear its future is bleak in this application. Corn starch is a marvellous material which used in gloves affords ease of donning, reduced tearing, dry comfort and in some aspects it is actually good for the skin. One of its mains strengths is now its debilitating weakness in that if there are residual extractable proteins on the glove surface it would tend to be absorbed into the corn starch and act as a transport agent.
