conventional specialty carbon blacks. “We are excited to bring this availability to the Americas and to partner with companies who have previously had to import acetylene-based carbon black,” said Stroh. “We see a growing interest in conductive blacks at every level – from ESD through to true conductivity.” Orion introduced new specialty carbon black
grades at NPE 2024 made from end-of-life tyre pyrolysis oil, which uses waste tyres as a feedstock and creates circular carbon black that can be certified by ISCC Plus. Orion offers ISCC Plus certification for multiple furnace-black grades made from different feedstocks at five different plants. “ISCC Plus verifies the transparency and traceability of sustainable raw materials in our value chain,” said Orion CEO Corning Painter in the press release. In June 2024, Orion announced that it was installing additional tyre pyrolysis oil tanks at its plant in Poland to increase production of circular carbon black. Stroh added that companies have a variety of goals for sustainability, including reducing their carbon footprint at their manufacturing sites, reducing carbon footprint of their products, and having recycled and sustainable sources for raw materials. “Companies have aggressive goals for the 2030 timeframe and beyond, and these new grades will help our customers meet their goals,” she said.
Orion says it is continuously expanding its
portfolio of conductive additives for cable applications to meet the increasing requirements in terms of dispersion and cleanliness without losing the focus on sustainability. “Over time, we’ve optimised the colloidal properties of legacy

conductive additives to ensure excellent dispersibility and product cleanliness in our newest grades plus those in development,” said Kevin Milks, Orion Marketing Manager for Polymers and Special Applications, in a press release.
Bio-based black US-based Bioregion Technology (BRT) has launched a series of bio-derived carbon additives produced from lignocellulosic biomass from agricultural waste. The additives have been through the USDA’s BioPreferred certification process and have 100% bio-based carbon content, said Brendon Bohnert, Senior Manager for Emerging Technologies at Nagase, which has
