Technological watch

bp and have signed a new agreement to work together to drive circular economy in the petrochemical activities at the Gelsenkirchen (Germany) chemical complex. Building on a long-established relationship between the two companies at the production site, the new collaboration will help to increase production of certified circular products that take used mixed plastics to make feedstock, thereby reducing the amount of fossil resources needed in the petrochemical plants at the site.

Advanced Recycling to Convert Used Plastic into Pyrolysis Oil
Certified circular polymers are part of SABIC’S TRUCIRCLE™ portfolio and are produced using , otherwise destined for incineration or landfill, into pyrolysis oil. The oil, which acts as an alternative feedstock to traditional fossil materials, will be processed at bp’s Gelsenkirchen refining site and then used by SABIC in its Gelsenkirchen polymer plants to produce certified circular products.
The final material has identical properties to virgin-based polymers and allows plastics to be recycled over and over again, with no loss of properties or characteristics. After successful trials in December 2020, polymer production using the alternative feedstock started at the site early this year.
“Advanced recycling allows us to increase the production of more sustainable materials and use our planet’s resources wisely, whilst reducing the use of conventional approaches such as landfill and combustion. Advanced recycling has a crucial role to play in the current recycling mix as it can capture value from plastic waste streams that have traditionally been ignored or discarded,” said Fahad Al Swailem, vice president, PE & Sales at SABIC.
bp and SABIC have a collaboration going back decades in petrochemicals at the Gelsenkirchen site, which is the starting point for the value chain of the chemical industry’s network in the northern Ruhr Area. The refining and petrochemicals site in Gelsenkirchen plays an important role within the chemical industry in North Rhine-Westphalia, Germany’s most populous state. bp operates one of the largest olefin plants in Germany, with a production capacity of around two million tonnes.
“This is an important milestone in our vision of achieving up to 30 percent of our ethylene and propylene production from sustainable, recyclable raw materials by 2030,” says Wolfgang Stückle, vice president refining and specialties solutions Europe & Africa at bp.
ISCC+ Certified Base Chemicals and Circular Polymers
The certified base chemicals from bp and the certified circular polymers from SABIC are recognized through the International Sustainability and Carbon Certification plus (ISCC+) scheme that certifies content and standards across the value chain from source to end product. The ISCC+ certification works on what is known as a ‘mass balance system’, meaning that for each ton of circular feedstock fed into the cracker and substituting fossil-based feedstock, a ton of the output can be classified as circular.
The circular polymers form part of SABIC’s TRUCIRCLE portfolio and services for circular innovations. The TRUCIRCLE portfolio spans design for recyclability, mechanically recycled products, certified circular products from feedstock recycling of used plastic, certified renewable products from bio-based feedstock and closed loop initiatives to recycle plastic back into high quality applications.
