Spill-Cure™ Opportunities and Prospects-Asphalt
(11/3/2008)
 
Employment of modifiers in the bitumen residue resulting from modern refining processes has increased as the sophistication of processing has extracted an increasing proportion of higher value products from crude oils. Indeed, specification of asphalt products has shifted in recent years from inferential formulations to the present laboratory rheology techniques where ground temperature extremes and traffic loads permit pavement system designers to apply exactly and only that needed for the task. Modifiers for bitumen have evolved from emulsifiers and simple polymers to complex mixtures of components designed to add back some of the 'life' extracted in refining processes. The purpose of such additives is to alter the performance of the pavement binder materials to address specific performance characteristics. A mixture of bitumen as a binder with size selected aggregates is commonly referred to as asphalt. Asphalt is the principal pavement material in use as it remains flexible in all temperatures, can be resurfaced and the performance tailored to placement location requirements. One component of increasing use to enhance asphalt performance is crumb rubber which itself is derived from grinding waste tires to very small sizes, extracting all wire and fibers. Such material enables asphalt mixtures to increase stiffness in high temperature or traffic loads, to resist reflective propagation of subsurface anomalies (such as cracks and seams) and to improve cold weather fracture performance. Tire crumb is attractive as is inexpensive, thermally and UV stable and easy to handle. It has limitations in that it will not remain in mixture with bitumen absent the presence of a compatible polymer with which it might cross-link. The idea being to chemically tie the rubber bit to the bitumen to assure the ability to make uniform mixtures which are storage stable at +325 degrees over time. The common material used to provide this linking between bitumen and rubber is polymers such as SBS, SEBS, and Kraton. Such materials have a cost of $1.00-3.00/lb. A common asphalt-rubber product would consist of 5% fine crumb at $130/ton and 2% polymer at $3000/ton added to a bitumen base costing $500/ ton. Ecser Spill-Cure™ can be used for blending into bitumen without need for polymers or by a greatly reduced amount. The selective amount of de-vulcanization permits the activation of the polymers in the rubber to perform the cross linking role with the bitumen producing a storage stable and easily mixed component of the asphalt whose characteristics can be tailored to the specific application need. The advantages of Spill-Cure™ also include the ability to be stored in mixtures at temperatures where ordinary polymers 'cook-off' or thermally degrade and lose their effectiveness. The primary applications for Spill-Cure™ are as a modifier in pavement maintenance products (emulsion seals, crack sealants and in friction course products), in roofing materials and in materials coatings. The market for pavement maintenance applications is estimated to be 100 million pounds annually, and growing. The increased cost of bitumen materials and the likely reduction in gasoline tax revenues (for several reasons) will place increasing pressure on pavement designers to improve performance of their products. As pavements are typically 6% bitumen and 94% stones, the pressure will surely increase to do more with less. Performance enhanced asphalts are the answer. Prices for Spill-Cure™ in this channel of $2,000 per ton are expected. Asphalt based roofing materials too are under pressure to improve their ability to withstand damage from impacts, deformation by wind cold weather cracking and UV damage. Replacement of asphalt shingles remains one of the top costs for home insurers and is an area of increasing emphasis with premiums now being tailored to the type roofing materials on the structure. Preliminary work with roofing firms leads me to conclude the immediate market potential to be 10 million pounds annually with growth to 50 million pounds within five years. Prices for Spill-Cure™ in this channel of $ 2,000 per ton are expected. Coatings include use of Spill-Cure™ modified bitumen’s for concrete structure water proofing, timber sealants and metal protection. While not likely to approach the pavement maintenance and roof materials, coatings promise to be a high margin contribution sales channel for Ecser. Prices of over $2,000 per ton are expected, this translates to a 50% savings.

A technical description of Spill-Cure™
(6/29/2006)
 
Oil spillage presents an ecological problem while oil spill cleanup is a financial problem. Therefore it is ideal for the industry to look towards inexpensive yet effective cleanup materials such as Ecser’s solution using waste tires.

Ecser’s new technology, based on its highly effective Counter-Cure™ process, has been able to achieve remarkable results using waste tire rubber as an oil absorption agent.

This new technology allows targeted destruction of the rubber vulcanization grid creating a substance with a high absorption capacity. In doing so the new substance must also be protected from dissolving in the oil spill; which is also achieved in an ingenuous manner.

Generally the dissolution of a rubber polymer in oil or any solvent occurs in two stages; initially the solvent molecules penetrate into the polymer, draw apart the polymer macromolecules, and become fixed inside the polymer matrix by physical (non chemical) bonds. This is commonly referred to as the swelling stage.

After substantial swelling occurs the polymer macromolecules may start to separate and transfer to the solvent where they may dissolve completely.
This is called the dissolution stage. Dissolution can generally occur only if the vulcanization cross links are thoroughly destroyed and the devulcanization is complete. Rubber polymers with a dense vulcanization grid can only allow minimal swelling so no significant quantity of oil can enter the polymer.

The challenge is to subject the rubber to a devulcanization regime that will produce a substance capable of maximum swelling yet maintaining sufficient cross links to prevent the rubber from dissolving in oil.

Ecser’s new technology is able to achieve precisely those conditions by creating a substance capable of significant swelling and with a high absorption capacity and with a very low cost.

New markets and value added uses for scrap tires and scrap rubber.
(6/29/2006)
 
Ecser Holding Corp, an innovator in rubber recycling technologies, announces an exciting new development that opens up new markets for scrap tire rubber and post-industrial waste rubber.

Building on Ecser’s patented Counter-Cure™ and Spill-Cure™ technologies, the company has engineered a new rubber substance with high value potential for various applications. While CounterCure allows companies to devulcanize their waste rubber and substitute it for virgin rubber in their master batch, Spill-Cure converts waste rubber into a substance that can be used as an oil absorbent for oil spill cleanup and remediation. By effecting a targeted destruction of the rubber vulcanization grid the Spill-Cure process creates a substance with a high absorption capacity

As crumb rubber manufacturers constantly seek new markets for their product, Ecser has consistently looked outside the traditional crumb rubber channels to find new markets for waste rubber. By expanding on Spill-Cure Ecser has now developed a product that can be introduced into broad consumer markets; which bodes well for crumb rubber manufacturers who may now find new and wider markets for their product.

Since Spill-Cure is designed to partially devulcanize waste rubber and allow rubber to swell and absorb oil, Ecser advanced the technology further so that it also makes an ideal aggregate material because it mixes well, can absorb oil and chemicals, and can function as a controlled release material.

Spill-Cure is easily molded and can be an ideal delivery vehicle for consumer chemicals such as pest repellents, anti microbial agents, malodor control, and agricultural additives.

Spill-Cure also performs well as a waterproofing sealant when mixed with asphalt for driveways or with roof coatings. Various construction applications have been identified as well including using Spill-Cure for insulation, soundproofing, waterproofing, and even as an additive into concrete.

Crumb rubber manufacturers who adopt Spill-Cure will find that they now have access to consumer markets with common household and garden products that can augment if not even surpass their existing markets for crumb. New industrial markets also appear as Spill-Cure is introduced to the construction and roofing industry.

The technology behind Spill-Cure is ingenious and innovative, yet the process is simple enough that it can be employed in almost any rubber manufacturing facility using industry standard milling and extrusion machinery.

Ecser expects that crumb rubber manufacturers, compounders, and rubber recyclers can utilize Spill-Cure technology to explore new markets for scrap rubber.
New use for tire rubber - Clean up oil spills!
(3/21/2006)
 
Ecser Holding Corp, an eco-friendly innovator in the field of rubber recycling, proudly introduces revolutionary new solutions for waste rubber,with the creation of Spill-Cure™

Based on its highly effective Counter-Cure™ technology to devulcanize waste rubber, Ecser has developed new applications using devulcanized waste rubber, opening up entirely new markets and opportunities for the industry.

Counter-Cure™ is a unique and innovative approach to recycling rubber. Using a patented technology, Ecser can enable recyclers, manufacturers, and compounders to convert waste rubber into a viable alternative to virgin rubber. This is achieved via Ecser’s proprietary chemicalmechanical process that is able to sever the sulfur crosslinks in cured rubber without damaging the carbon polymer chain and thus retaining the rubber properties desired for manufacturing. The process, which is ambient, non toxic, and mated to industry standard equipment; can be implemented “in house” in almost any rubber manufacturing facility allowing anyone in the industry to take advantage of an economically viable alternative to virgin rubber.

By focusing research efforts of finding solutions for other environmental concerns that have eluded resolution, Ecser can serve a dual purpose; first to redirect waste rubber from landfills in to productive and lucrative markets and second to solve environmental problems existing from other industry pollution.

With the creation of Spill-Cure™, Ecser’s new technologies include some exciting solutions for serious environmental issues. The first new development targets the oil industry presenting a solution for a major industry concern; Oil spills.

Using recycled tire rubber Ecser has been able to create a new engineered rubber substance that can absorb up to 6-8 times its weight of spilled oil. This pioneering technology can be applied to marine oil spills providing a highly effective solution to clean up and recover spilled oil. The rubber material continues to float allowing it to be removed from the waters surface and finally the oil can be extracted from the rubber material and cleaned providing a complete recovery solution rather than simply assisting in cleanup.


An effective oil recovery solution has yet to be developed that can offer such a comprehensive and effective result. Ecser’s oil recovery technology has numerous applications both terrestrial and marine including;

- For truck stops and fleets,
- Garages,
- Marinas,
- Commercial ports,
- Insulation for fuel tanks at filling stations,

. . . and likely many more.

In order to complete the eco-friendly circle, Ecser has further developed applications for the recovered rubber material that is saturated with oil so that by solving one ecological crisis we are not creating another one. A likely use for the rubber remnants is as an additive to asphalt and to coat gravel before final road surfacing. The material can also be used in compounding as a processing aid since it has rubber that is super-saturated with oil.

Ecser continues this approach to waste rubber and other prevailing industrial environmental phenomena; always looking for methods to tackle serious problems in an eco-friendly yet commercially viable manner.

Ecser invites participation from the oil industry as well as rubber recyclers, the public sector, and any interested party.
