News: Tire Recycling & Pyrolysis

Gradeall’s team pinpoints that the current problem in OTR tyre recycling is that these huge tyres take up a lot of space and are very heavy at approximately 600 kg per tyre making them take up a lot of space, they are impossible to move by hand and costly to transport due to low amount of material fitting on a trailer. Using the Gradeall OTR cutting range these large tyres can be cut down into easy to manage segments weighing under 25Kg which means they can be lifted and moved around by anyone. These segments can be baled, shredded, sent for pyrolysis or any of the further recycling methods that are available to conventional tyres.

As one of the leading tire manufacturers in China and one of the biggest in the world, ZC Rubber says it is the only experimental unit designated by the Ministry of Commerce, the Ministry of Finance, the Ministry of Industry and Information Technology of the People's Republic of China and the China Tyre Recycling Association. While focusing on the tire industry, ZC Rubber says it took the lead to build up the production, sales, recycling and reuse of the whole life cycle tire management and development model. Besides, ZC Rubber says it has been actively involved in development of environment-friendly technologies, basing its development model on sustainable resources, and carrying out pilot projects for the recovery and comprehensive utilization of waste tires.

Tyre Stewardship Australia (TSA) reports that it will no longer be accepting applications from new entities seeking accreditation for the baling of whole end-of-life tyres for export. According to the statement, TSA makes this decision in light of the recent announcement made by the Council of Australian Government (COAG) to ban the export of whole baled tyres. TSA highlights that this action is intended to assist current accredited organisations transition from baling whole tyres for export to other processing methodologies.

A team of researchers at the National University of Singapore (NUS) reports about achieving a major technological breakthrough by converting end-of-life tires into super-light aerogels that have a wide range of applications. This is the first time that aerogels are made from end-of-life tires, the University reports. The new rubber aerogels demonstrate remarkable properties — they are extremely light, highly absorbent, very durable, and they are also very efficient at trapping heat and sound.

Crude oil prices are testing sub $20 territory, some analysts predict further decreases. This puts immense pressures on tire pyrolysis operators who depend on fuel oil sales as their main source of revenue. Experts at Weibold have engineered a cost effective upgrade program for batch reactors that will: • convert your reactor to continuous processing • add heat cycles to improve output and separation • allow you to keep processing the same feedstock • increase capacity 3 - 4 fold • reduce energy costs

A trial organised by Transport for Victoria saw the introduction of OLEXOCRUMB®, the most recent product innovation from Puma Energy’s Global Bitumen Technology Centre in Altona, Victoria (Australia). The new asphalt binder was trialled in close collaboration with Boral Asphalt, as part of the Boral/Puma technology program. The company reports that OLEXOCRUMB® was specifically formulated to comply with existing Australian roads polymer modified binders (PMB) specifications.

The association reports that the world consumption of NR fell 19.6%, year-over-year, during the first quarter of 2020, as per the preliminary estimates and forecasts of individual countries. The consumption anticipated during the second quarter is down 1.5% compared with the same quarter a year ago. At the same time, the world production of NR increased by 1.8%, year-over-year, during the first quarter of 2020, according to preliminary estimates and forecasts of individual countries. The production anticipated during the second quarter is up 3.6% compared with the same quarter a year ago.

In the end of this article we make an estimation of a possible annual market size of recovered carbon black, modestly assuming virgin carbon black substitution rate at 20%. Hint: numbers suggest that recovered carbon black production is a profitable business rich in opportunities. Traditionally Carbon Black (CB) has been used as both a reinforcing agent and filler in automobile tires. Along with better understanding of CB’s unique properties as a material, it is presently used in a much wider range of applications across a large variety of products – car tires, conveyor belts, inks, plastic pipes, rubber mats, shoe soles and so forth. Virgin CB contains only trace amounts of impurities and carbon content is very close to 100%.
