The last issue of Tyre Asia published in December/January featured the second part of Robert Weibold’s interview on tyre recycling. Earlier, Tyre Asia interviewed Robert Weibold on the state of the tyre recycling industry. As the problem of waste tyre accumulation and disposal around the world gets acute, Robert shared his view on how to sustainably tackle the problem.

Commenting on the term of the new CEO, the company revealed that he will serve as a company’s head until Thomas Redd, CEO of Pyrolyx USA will be ready to be in charge of the corporation and will not be distracted by the development of the Indiana-based recovered carbon black facility, which is anticipated to begin functioning in June this year. The facility will be able to recycle more than 12,000 metric tons of scrap tires.

Scandinavian Enviro Systems and Treadcraft Limited extend the MoU that was signed on June 29th, 2018 by six months. The parties intend to establish a Joint Venture for co-ownership of a tyre pyrolysis plant with an annual capacity of 30,000 tonnes tyres. The plant is planned to be established at 1501 College Avenue, Niagara Falls, New York, USA. “The fact that we have a specified site for the plant is an important step forward. We will now continue to formalize the terms and conditions of the project. Within the next six months, legal, financial and license issues will be clarified, and a plant order will be established. Joint ownership is in line with Enviro’s new business model and it means that we will benefit from the returns that will be generated by a plant” says Thomas Sörensson, CEO of Enviro.

Annually, New Zealand generates 5 million scrap tires and the biggest part of them end up at landfills or as waste export. To solve the problem, a company Eneform has developed a low emissions system that has the recycling capacity of 1.5 million scrap tires per year. Currently, the firm seeks expansion within the country and wants to upgrade its recycling capacity up to 5 million tires per annum. To develop its new system, Eneform relied on traditional pyrolisys and transformed it so the company could run a cost-efficient tire recycling plant. Southern Cross Engineering, Petrotec and Hineuru Holdings helped Eneform develop the innovative tire recycling facility.

The move comes after the Austrian firm earlier presented its innovative way of tire recycling that seeks to recycle rubber from tires into solid carbon, also known as recovered carbon black. Alternatively, the method allows getting a hydrocarbon mixture like pyrolysis oil and gas. Apart from commercial application of recycled products, the process is of value as it is totally in line with circular economy’s principles and it does not require external energy sources.

In tire recycling, one can create different types of output depending on production technology. From each output type, several applications can be produced, hence different industries and markets can be targeted. Currently, there is a wide range of products that can be developed via tire recycling. However, to significantly increase profits, R&D activities prove to be an integral part of tire recycling. Success of products on the market largely depends on the regions where they are sold.

A new tire recycling line has been commissioned and installed in Poland by American tire recycling equipment manufacturer CM Shredders. The company says it is the second CM line in Europe intended for tire pyrolysis / gasification industry. CM Shredders (formerly Columbus McKinnon) revealed that its system is capable of manufacturing rubber free of wire, which may be used as a feedstock in tire pyrolysis. In addition, the equipment produces purified steel wire from tires.

We are glad to announce that our team has been enriched by an expert in tire pyrolysis, Pavol Fehér, PhD! To introduce our new expert to you, we list below his qualifications and professional background. Focus of tire pyrolysis and fuel quality enhancement Pavol Fehér worked on all aspects of thermal conversion of waste materials: from feedstock preparation to end products in R&D projects at Slovnaft Refinery and MOL Group. He researched treatment feasibility of waste materials, particularly waste tires and plastics, and worked with technologies designed to improve pyrolytic fuels.

Oil makes up approximately 35-45% of pyrolysis output depending on process conditions. Recovered fuel oil consists of three fractions with the middle fraction prevailing and it cannot be considered a substitute for traditional fuels before purification and sometimes additional treatment. Width of application of tire-derived pyrolysis oil depends on regulations in particular countries where a project is carried out. In countries with strict environmental protection regulations pyrolysis oil may require additional treatment and refinement, which in turn will increase production costs and lower profit margins.
