End-of-life tires represent a significant global waste problem. Their robust structural and chemical properties pose challenges for traditional recycling methods. With 1.5 billion tires manufactured annually, the environmental impact is substantial, with each tire contributing approximately 300 kg of CO2 emissions. The increase in tire production, driven by the rise of electric vehicles, underscores the urgency for effective recycling strategies. Waste tires are not only difficult to dispose of but also pose environmental hazards when dumped or incinerated. Traditional disposal methods like open dumping and incineration lead to issues such as fire hazards, mosquito breeding grounds, and the release of harmful pollutants.

Recovered Carbon Black (rCB) producer Klean Industries Inc. will become equipment supplier for five more India-based rCB upgrading facilities after signing a letter of intent; this move brings an overall number of facilities in the Asian country developed within the last two years to eight. The corporation has noted that the demand for rCB is substantial, and Klean has expansion plans throughout Asia. The demand growth comes at a time when the industry is witnessing virgin carbon black deficit and import levies in India.

When a tire is recycled through tire pyrolysis, the solid material that remains from the pyrolysis of the rubber, commonly referred to as tire char or raw rCB, is composed of carbon black and varying amounts of impurities, such as silica, zinc, and sulphur. The latter are found in the original tire as additives to the production process.

The global manufacturing community is certainly used to facing and overcoming challenges, yet 2022 has been particularly problematic with the pressures of soaring energy costs and resource limitations. These obstacles are forcing the sector to look afresh at sustainable raw material alternatives, including Recovered Carbon Black. . Made from recycled waste tyres, rCB can, depending on the applications, fully replace virgin carbon black or be blended with and integrated into existing recipes, offering sustainability & cost benefits.

In a world grappling with environmental challenges, finding ways to recycle and repurpose materials has never been more critical. At the heart of this movement is recovered carbon black (rCB), an innovative material derived from end-of-life tires (ELTs) through pyrolysis. This promising material offers a pathway to sustainable, high-value applications that can help reshape industries ranging from energy to environmental remediation.

ASTM International, formerly the American Society for Testing and Materials, is a globally recognized leader in developing and delivering voluntary consensus standards. Founded in 1898, ASTM provides a forum for producers, users, consumers, and other stakeholders to create and update standards transparently. The organization supports industries worldwide by offering over 12,000 standards that enhance safety, quality, and performance across various sectors. ASTM standards are utilized in research, product development, and quality assurance to improve public health and safety.

The tire waste recycling industry is transforming after 25 years of gradual progress. Traditionally, recycling focuses on mechanical processes to separate and recover rubber, steel, and fiber from End-of-Life Tires (ELTs), with applications developed for products like sports turf, civil engineering, mats, and even fuel for cement kilns.

Wastefront AS has announced a significant partnership with Weber & Schaer, one of Europe's largest distributors of rubber industry products, for the offtake and on-sale of their Recovered Carbon Black (rCB). According to Wastefront, this agreement secures a fully circular supply chain for end-of-life tires (ELTs) in the UK. The deal initially covers a minimum of 35% of rCB produced at Wastefront's Sunderland plant, with potential for future expansion. By manufacturing renewable fuels and new tires using ELTs and rCB, Wastefront moves closer to its goal of creating a Green Global Industrial Platform. With Weber & Schaer's expertise in rubber, carbon black, plastic, and adhesives distribution across Europe, Wastefront's ELT solution contributes to the global circular economy while expanding into new markets.

British Plastics Federation recently released an article about Waverly Carbon's sustainable recovered carbon black (rCB) and how it could be used in manufacturing process. The article also covers Waverly Carbon's collaboration with its official UK distributors Lawrence Industries Ltd. The widespread use of virgin carbon black, derived from finite fossil fuel resources, poses environmental challenges due to its production process, high energy consumption, and associated emissions.
