Recovered Carbon Black – ConBlack®

What is recovered Carbon Black?

Recovered Carbon Black (rCB) is a processed solid residue created from the pyrolysis of end-of-life tires (ELTs). rCB can be made from many types of rubber waste, but ELTs are the most convenient because of their wide availability.

The pyrolysis process recovers various virgin Carbon Black (vCB) grades and mineral fillers present in the rubber. The raw product is called a char. The char is further processed, milled, and pelletised to become recovered Carbon Black. rCB contains around 20 per cent less carbonaceous material in comparison to virgin Carbon Black, because of the presence of minerals. However, rCB is still a high-quality product with many applicable uses. 

The in-rubber performance of rCB produced by Contec is very similar to several grades of virgin Carbon Blacks that are widely used in the tire manufacturing industry. The rCB carbon footprint is over 80 per cent lower in comparison with vCB. 

Meaning, that there is a large push in the tire manufacturing industry to pivot towards rCB in production.

Recovered Carbon Black applications

Recovered Carbon Black is a sustainable alternative to virgin Carbon Black. There is a high interest in rCB from tires, manufactured rubber goods, plastics and pigment industries.

Less carbon footprint with rCB

Switching to recovered Carbon Black (rCB) reduces CO2 emissions by over 80 per cent for each ton of Carbon Black produced. In other words, if rCB replaced only 10 per cent of vCB production, annual global CO2 emissions would be reduced by a striking 2.7 million tonnes.

Recovered Carbon Black by Contec

At Contec, we provide recovered Carbon Black (rCB) of consistent and stable quality.

Contec’s ConBlack® comes from an established technological and operational process  – from the initial tire shredding and unique pyrolysis process to the post-treatment line based on the best-in-class solutions. 

Our in-house testing laboratory ensures that our customers get the highest quality rCB possible.

Why choose Contec products

01. High-quality products ensured

Contec products meet quality standards in terms of consistency, safety, and repeatable quality. 

At Contec, rigorous quality control measures are established throughout the process. Quality is checked regularly – from the initial tire shredding and pyrolysis process to the testing of the end product in our dedicated in-house lab.

We recognise the importance of maintaining these high standards, and our process reflects this commitment. 

The preventative maintenance program and our engineers will also take immediate steps to identify and rectify the cause of any pyrolysis line needs.

It’s important to have well-maintained equipment for quality and consistent products. Our on-site team of technicians and engineers undergo regular preventive maintenance schedules and quality checks.

02. Continuous innovation and technology development

Our research and development department is committed to applying new technology and processes to create innovative and sustainable solutions. 

We continue to conduct joint R&D initiatives to improve the technology resulting in us having a firm understanding of the design quality. 

We developed the pyrolysis process through collaboration with experts in the field.

Our team of in-house engineers, external partners, and technological institutions like the Warsaw University of Technology have been involved in technology development. Special attention was given to constructing a process that is suitable for a variety of applications.

03. We take safety seriously

Most industrial processes have risks and hazards associated with them, and the pyrolysis of ELTs is no exception. 

We have managed to maintain an exemplary safety record by investing in equipment, sensors, procedures, and policies to keep our employees safe.

All of the processes at our full-scale production location comply with safety and quality standards which are reviewed by external auditors. 

We regularly perform operator training, supported by process engineers 24/7, and have safety procedures in place. We also apply automated safety systems to the technology.

As experienced operators, we know that safety comes with preventative maintenance.

04. Sustainability is part of our mission

Sustainability is at the core of our mission. 

We aim to recycle 100 per cent of the ELTs that come into our plant to help reduce carbon emissions and cut material waste. The technology and processes that we’re helping to improve allow us to achieve this mission. 

We strive to improve efficiency and sustainability across our operations and limit our carbon footprint.

We’re proud that our products have a drastically lower carbon footprint in comparison with fossil-fuel-derived counterparts.
