 The carbon black industry is transforming significantly as demand for sustainable alternatives grows. Klean Industries has developed an advanced process for upgrading scrap tire char (pyrocarbon) into high-quality recovered carbon black (rCB), providing a cost-effective, low-emission alternative to virgin carbon black. This breakthrough innovation reduces environmental impact, supports circular economy principles, and meets the increasing demand for sustainable materials in the rubber, plastics, and coatings industries.
Vancouver, Canada - Klean Industries Inc. “Klean”- an international developer of comprehensive waste-to-value solutions. Focused on vertical integration of clean energy and recovered resources. We deliver scalable, reliable environmental energy solutions. Klean is pleased to announce today that samples of raw pyro-carbon residue from Klean Industries scrap tire pyrolysis recycling plants were upgraded using patented and proprietary post-treatment technology.
Independent tests confirm that the generic recovered carbon char processing successfully upgrades raw pyro-carbon residue (char) into cost-competitive grades of black reinforcing fillers that can be reused in rubber manufacturing to replace or blend with carbon blacks and as an asphalt modifier. The reinforcing properties are related to the quality of the raw heterogeneous pyro-char.
In every case studied, the upgrade recovered carbon black (rCB), clearly illustrated the tensile properties were always better than those of the N-900 series carbon blacks. In tests by BFGoodrich, tensile strengths exceeded those of N-600 carbon blacks on controlled runs.
The patented technology was introduced at the Carbon Black 1996 World Conference “A Black Filler for Rubber Prepared from Tire Pyrolysis Char” as an economical solution necessary to commercialize pyrolysis of scrap rubber. Reinforcement qualities were equivalent to carbon blacks with particle sizes at 0.05 to 0.10 microns. The initial demand for recovered carbon black was estimated at 50,000 tons per year without considering additional marketing and the tire and asphalt markets for rCB products. Since then, many successful upgrading tests have been integrated with other pyrolysis technologies and after the treatment of the raw non-commercial pyro-chars.
The US EPA report Markets for Scrap Tires states in Section 8 on pyrolysis: “Pyrolysis units are expected to have minimal air pollution impacts” but adds: “If markets for char cannot be developed, the char becomes a major solid waste problem.”
The Rubber Manufacturers Association (RMA) describes carbon black as an essential ingredient in nearly all rubber products to improve properties such as tensile, wear resistance, and modulus. Scrap tires and rubber can contain 25% to 35% carbon black. According to the Freedonia reports, the global demand for carbon black will grow 3.4% yearly through 2006 to 8.7 million metric tonnes.
A modular 4,000-per-day passenger tire equivalent pyrolysis plant can produce 3,500 tonnes of rCB per year or less than 0.05 percent of the present carbon black market, allowing for significant niche product market growth potential. The surplus of regional scrap tire pyrolysis feedstock is not subject to the volatility of the imported oil presently used to manufacture carbon blacks. This can permit stable long-term price guarantees.
In earlier tests, reinforcing fillers were also obtained by rCB upgrading of pyrolyzed automotive shredder residue, often referred to by the industry as “ASR” or “fluff.” In cooperation with the Vehicle Recycling Partnership, USCAR (General Motors, Ford, and Daimler-Chrysler), General Motors provided 40 tonnes of this raw pyrolyzed ASR material for these tests.
Tests by the Indiana Department of Transportation and Purdue University, sponsored by the US Department of Transportation, show cost-benefit application potentials for improving rutting resistance by modifying asphalt using rCB products.
A summary of this extensive testing and the potential for using scrap tires and ASR-derived rCB reinforcing fillers for asphalt modification is planned for the Second Rubber Modified Asphalt Conference, sponsored by the RMA and American Chemical Society Rubber Division, to be held in San Antonio on May 18-19, 2005.
Recycling is an increasingly important issue confronting the auto industry. The European Union will require that 85% of every vehicle be recycled by January 2006. In France, the creation of Aliapur with eleven rubber tire manufacturers demonstrates this Group’s determination to pursue an active policy of recycling end-of-life tires (ELT). Efforts requiring manufacturers to increase recycling responsibilities and End-Of-Life Vehicles (ELV) programs are underway in the U.S. as well.
The patented rCB technology is a breakthrough, allowing the potential for plastic, rubber, and automobile industries to meet these recycling objectives.
