Above: Orion’s facility in the city of Huaibei in Anhui province, China, will produce


carbon black for a variety of applications, including coatings, printing inks, rubber, polymers, fibre and rubber


masterbatch for a range of polymers. Carbon black supplier Orion offers ISCC Plus


certification for multiple grades made from different feedstocks at five different plants. Three facilities – in Texas, Ohio, and Poland – were recertified in 2023, and the Cologne, Germany and Ravenna, Italy facilities were certified for producing circular and bio-circular raw materials. “ISCC Plus verifies the transparency and traceability of sustainable raw materials in our value chain,” said Orion CEO Corning Painter in the press release.


Renewable The company notes that it developed and commer- cialised carbon black from renewable feedstocks, such as vegetable oils, oils derived from waste, and residues from agriculture or forestry, a decade ago. The company is also a partner in the European BlackCycle consortium, which has developed sustainable carbon black using oil from an EOL tyre pyrolysis process. In June, Orion announced that it was installing multiple tyre pyrolysis oil tanks at its plant in Poland to increase production of circular carbon black, which is used in multiple applications. At NPE 2024, the company introduced two new specialty carbon black grades made from EOL tyre pyrolysis oil. The products, Printex kappa 100 Beads and Printex kappa 100 acetylene conductive additive, provide both pigmenting and conductiv- ity for wire and cable as well as pipe, film, fibre, packaging, and automotive applications. Orion’s latest for thermoplastics is Printex


chroma 500 Beads, a high-jetness carbon black designed for engineered plastics that balances high jetness and dispersibility. “This is a product our customers have been demanding for a long time. It’s ideal for injection moulded automotive parts, household appliances, electronics and other applications with a shiny, glossy finish,” said Tilo Lindner, Vice President of Global Marketing for Specialty at Orion, in the June press release.

Pomini is working with WF Recycle-Tech on a new, patented technology to use Farrel Pomini’s continu- ous mixer for pyrolysis of EOL tyres. The output is 50% tyre-derived oil, 10% syngas (which is used to generate electricity for the process) and 40% recovered carbon black, the company reports. A benefit of this equipment for this application is its modularity, which makes it suitable for the smaller, regional nature of EOL tyre processing, said Paul Lloyd, Farrel Pomini President. A typical size handles 10,000 tonnes/year of tyre scrap. Farrel Pomini has produced its own 40-55% black masterbatch in a research and development environment as samples.


White pigments Titanium dioxide (TiO2


) is broadly used for white


pigmentation in plastics and other applications. The Titanium Dioxide Manufacturers Association (TDMA), representing European manufacturers, recently announced an updated LCA measuring the climate change impact (ie, a carbon footprint measure) for TiO2


. The LCA used data from mem-


bers across 33 production sites. Tronox has new products in development that


are targeted for very specific thermoplastic applica- tions, said Steve Forrest, Director of Global Market- ing at Tronox. “Working with customers and under- standing the specific polymers and intended applications allows new, specialised TiO2


products


offerings to


be developed to enable performance,” said Forrest. He added there is a drive to provide TiO2


that are more sustainable, and suggested that Tronox can do this effectively because it is vertically integrated and controls 85% of its own feedstock as well as the TiO2


pigment factory, so that the com-


pany has direct control over almost two-thirds of the total carbon footprint. “We can take direct and achievable action with current technology to reduce our footprint in the short term, while also mapping out longer term and developing technology options for future reductions,” said Forrest. US Silica launched EverWhite Pigment, an


engineered high-white pigment for various applications, including plastics, in 2023. The pigment can be used to partially replace or complement other inorganic white pigments, such as TiO2


, the company says. For US customers, it is a


domestically sourced product, for cost savings and access, the company added. In mid-2024, the company was acquired by Apollo Funds. Finland-based FP-Pigments produces opacity pigment masterbatches for thermoplastics that are composites of TiO2


and calcium carbonate. These www.compoundingworld.com
