Materials New additive

Materials New additive grades US-FDA approved Perstorp (Malmö, Sweden) has acquired food contact use approval for its Capa for Bioplastics product grades 6500D and the new 6800D. By adding Capa 6800D to its product portfolio, Perstorp can now offer a higher molecular weight product to give customers more choices and flexibility in finding the right formulation. Capa 6500D and Capa 6800D now approved for food contact use in the US. (Food Contact Notification by FDA) • The new Capa 6800D for Bioplastics extends Perstorp’s range of products for biodegradable food applications • Capa for Bioplastics is durable, stable and easy to process as well as offering best-in-class biodegradability Bioplastics is a focus area for Perstorp. It is an important part of the company’s commitment to the environment and vision for a more sustainable future. Capa for Bioplastics exhibits excellent biodegradability properties and can improve bioplastic solutions, as well as enabling unique product characteristics. Capa for bioplastics (ε-polycaprolactones (PCL) can serve as a mechanical property enhancer for renewably sourced biopolymers, as well as a processing aid. In the bioplastics market, Capa is typically used for applications like bags and films, paper cups and packaging. “We have had food contact approval in Europe (EFSA) already for a few years,” says Jesper Fahlén, global product manager Capa. “This approval for our Capa 6500D as well as for the new Capa 6800D verifies that Capa is safe for food applications, enabling bioplastic packaging for a more sustainable future.” Performance without compromise The new Capa 6800D grade further extends Perstorp’s Capa portfolio. It is a high molecular weight linear polyester derived from caprolactone monomer. Like Capa 6500D, the Capa 6800D variant does not compromise on performance; being just as durable, stable, and easy to process while offering best in class biodegradability. “The bioplastics market is rapidly growing and Perstorp sees huge potential for biodegradable packaging and food applications,” says Marie Grönborg, Executive Vice President at Perstorp. “With the broader portfolio we meet our customers’ need for formulation efficiency by offering different choices of molecular weight. By helping manufacturers move from conventional plastics to bioplastics we are, together, reducing the pollution our planet is facing.” MT Leading Event on Carbon Capture and Utilisation 15 – 16 March 2018, Cologne (Germany) Conference Team Jutta Millich Partners, Media Partners +49 (0)0561 503580-44 Dr. Asta Partanen Sponsoring +49 (0)2233 4814-59 Achim Raschka Programme +49 (0)2233 4814-51 Conference highlights and main topics • CO 2 for feed – proteins made from carbon dioxide • CO 2 for platform chemicals and polymers • CO 2 for future fuels • CO 2 for aviation kerosene • Sustainability & climate change mitigation potential • Key drivers: renewable energy & hydrogen production • Artificial photosynthesis as future technology • Political framework & visions Newsticker on Carbon Capture and Utilisation!

Materials Biobased aniline for Polyurethanes Covestro (Leverkusen, Germany) has scored a research breakthrough for the use of plant-based raw materials in plastics production: aniline, an important basic chemical, can now be derived from biomass. The materials manufacturer achieved this by collaborating with partners on the development of a completely new process, initially in the laboratory. Until now, only fossil raw materials had been used for the production of aniline, which plays an important role in the chemical industry and is used as starting material for numerous products. Following its success in the lab, Covestro plans to further develop the new process together with partners from industry and research. The first step is to upscale the process in a pilot plant with the ultimate goal of enabling the production of bio-based aniline on an industrial scale. That would be an unprecedented achievement in the chemical industry. Unprecedented achievement About five million tonnes of aniline are produced annually worldwide; the total volume has been increasing by an average of about 5 % every year. With a production capacity of about one million tonnes, Covestro is among the leading producers. The company requires aniline as a precursor for rigid polyurethane foam, a highly efficient insulating material used in buildings and refrigeration systems. “The market is showing great interest in ecologically beneficial products based on renewable raw materials,” said Covestro Chief Commercial Officer Dr. Markus Steilemann. “Being able to derive aniline from biomass is another key step towards making the chemical and plastics industries less dependent on fossil raw materials and market fluctuations. With this, we are pursuing our vision of making the world a brighter place.” “The process currently under development uses renewable raw materials and produces aniline with a much better CO2 footprint than that manufactured with standard technology,” said Covestro project manager Dr. Gernot Jäger. “This also enables our customers to markedly improve the CO 2 footprint of their aniline-based products.” And the reactions would take place under milder conditions. The ecological aspects of the process are also being thoroughly evaluated by external institutes. 100 % of carbon from biomass The industry currently derives aniline from benzene, a petroleum-based raw material. But industrial sugar, which is already derived on large scale from, for example, feed corn, straw and wood, can be used instead. The newly developed process uses a microorganism as a catalyst to first convert the industrial sugar into an aniline precursor. The aniline is then derived by means of chemical catalysis in a second step. “This means 100 % of the carbon in the aniline comes from renewable raw materials,” explained Jäger. Covestro is working with the University of Stuttgart, the CAT Catalytic Center at RWTH Aachen University, and Bayer AG (all Germany) to further develop the process. “This interdisciplinary, motivated team combines all the needed expertise at a very high level and is the basis for continued success,” said Jäger. The long-term research project will receive funding for a period of two and a half years through the FNR (Fachagentur Nachwachsende Rohstoffe e.V.), a project agency of Germany’s Federal Ministry of Food and Agriculture (funding code: 22010215).
