News: Tire Recycling & Pyrolysis

Aliapur – a French end-of-life tire management authority – recently announced a call for applications to participate in a tender to renew end-of-life tire collection and recycling contacts for 2021–2024. The authority says that the estimated volume of end-life-tires to be processed in this time span will reach over 380,000 tons of tires. The authority highlights that there will be several consultations with regard to the tender, and they will take place this April. According to Aliapur, Tender arrangements are expected to start in the very beginning of the next year.

In its recent press release, Ecopneus – Italian non-profit end-of-life tire management authority – informed about the reduction of the environmental contribution levied on new tires, greater controls on online tire purchases, better service for tire specialists and more stringent collection obligations to avoid any risk of end-of-life tire disposal in the open environment. These are the main novelties of the new Decree for the management of ELTs (DM 182/2019), introduced to improve the end-of-life tire recycling industry in Italy. Ecopneus says that this way the industry will have clearer and more transparent rules for all parties involved, for the benefit of operators and for an increasing recycling of tires.

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.
