Continental continues to step up its activities to ensure a circular economy. Recently, the tire manufacturer added recovered carbon black (rCB) to its newly produced Super Elastic solid tires at its tire plant in Korbach, Germany, thus reducing the use of fossil raw materials and CO2 emissions. Solid tires such as Continental’s SC20+ already contain around 60 percent renewable and recycled materials thanks to their high natural rubber content. By 2050 at the latest, Continental aims to use 100 percent sustainable materials in its tire products.

On 7 July, Newcastle University and Wastefront announced their partnership that will focus on the characterisation and enhancement of Wastefront’s recovered carbon black (rCB). As one of the UK’s top universities and a world leader in sustainability, Newcastle University’s partnership with Wastefront will see cutting-edge industry innovation emerge from research conceived in the North of England - ensuring the region is at the forefront of progressing circularity across Europe.

Bridgestone Americas and Dow have partnered to develop B-SEALS, a recyclable, silicone-based tire sealant technology. The extended mobility solution will be introduced at the upcoming 2022 Silicone Expo in Detroit (June 21-23), and represents more than four years of joint research and development between the two companies.

This article should give an overview over the recent development trends regarding the options for an upgrade of the tire-derived oil (TDO) with chemical and physical techniques. In two previous articles we have already dealt with the production of limonene and highlighted the advantages of fractional distillation of TDO. Introduction Refiners around the world are looking for alternatives to producing fuels from petrochemicals only. This is due to expected future declines in crude oil reserves combined with significant fuel demand growth expectations throughout the world and increasing environmental awareness among the population.

The company receives truck tires from local businesses, separates the steel from the rubber and crushes the rubber into a crumb that is fine enough for roads, playground surfaces and rubber ramps. Mr. Pennington says that the company recycles 100% of tires arriving to the facility. The general manager said while other companies exported old tires for recycling, their aim was to recycle material in the Western Australia. According to the general manager, after cutting the tire walls, they stripped the rubber from the bead, extracting the steel to go to scrap metal recycling.

During the last eight month, waste management centre Tadweer based in Abu Dhabi has processed almost 7,000 tons of scrap tires at its Gulf Rubber Factory; thus, it constitutes the daily recycling rate of 28 tons of tires. The move to establish the plant was made by Tadweer with an aim to process various waste, which could be further used as raw materials. According the company’s head Salem Al Kaabi, the recycling at the factory is conducted in accordance with the top global standards. The Middle-Eastern factory, equipped with tire recycling systems from Europe capable of manufacturing crumb rubber granules of various shapes, was launched 7 years ago. The process is sustainable and environment-friendly.

Replan is committed to enhancing collaboration among various tire recycling projects to facilitate information sharing and create new cooperation opportunities. By connecting diverse initiatives, the goal is to merge isolated efforts and products made from recycled tire materials (RTM) into European market.

Apollo Tyres, the international tire manufacturer, is readying itself for sustainable mobility solutions. The company has now developed passenger vehicle tires with 75% sustainable materials. Apollo’s new sustainable product comprises many featured compounding ingredients in different components of the tires, including bio-based and recycled materials. The sustainable natural rubber, used in these tires, have been sourced from suppliers who have public commitments to sourcing and/or traceable to specific plantations, in accordance with the company’s sustainable natural rubber policy.
