  • First biobased coating hardener for lightfast polyurethane coatings


    At eMove360° Europe 2018, the international trade fair for Mobility 4.0 in Munich, Covestro was awarded one of the coveted MATERIALICA Design + Technology Awards 2018. With the world's first biobased hardener for lightfast polyurethane coatings, the company managed to prevail in the "CO2 Efficiency" category.

    mFor years, Covestro has been increasingly using alternative raw materials to manufacture its products, also to reduce its own dependence on fossil resources. The material manufacturer is thus meeting the growing interest in products on this basis and is presenting itself as a pioneer in terms of sustainability.

    Covestro experts Hiep Tran (second from right) and Nusret 
    Yuval (second from left) are much pleased about receiving the MATERIALICA 
    Design +Technology Award 2018, in the "CO2 Efficiency" category. 

    Improved ecological footprint

     "Our hardener is of similar high quality to its petrochemical counterparts," explains Hiep Tran, project manager for the biobased hardener in the Coatings, Adhesives, Specialties segment at Covestro. "With a biomass proportion of 70 percent, however, it achieves a 30 percent better ecological footprint than comparable fossil products.”

    In addition, its properties are also comparable, enabling processors to use formulated coatings on their systems with minimal adaptation costs. Coatings based on Desmodur eco N are equally suitable for automotive, plastics, wood, furniture and industrial coatings.

    Promising drop-in solution
    Along with alternative raw materials, industries such as the automotive industry rely above all on energy savings and the possibility of using existing processes and plants – at competitive prices for the products they use.

    The polyurethane raw material Desmodur eco meets all these requirements: The hardener is produced from fermented feed maize and thus conserves fossil resources. Compared to conventional products, several process steps are saved during its manufacture.

    First near-series car paint job
    Last year, a project team consisting of employees from the vehicle manufacturer Audi, the BASF Coatings division and Covestro reached a new milestone: for the first time, Audi Q2 test bodies were successfully coated with a clear coat of the bio-based hardener. The application took place at the Ingolstadt plant under near-series conditions on existing systems. One of the vehicles was exhibited at the European Coatings Show from 4 to 6 April 2017 in Nuremberg.

    Desmodur eco N is just the beginning: Covestro is expanding its product range to include a large number of variants with different properties – such as the recently launched water-soluble product Bayhydur eco, which is perfectly tailored to the requirements of high-performance waterborne coatings. At the same time, Covestro and its partners are working on the development of next-generation biobased raw materials from cellulose and waste biomass.

    Renowned award
    The MATERIALICA Design + Technology Award is presented to products and concepts that meet demanding criteria such as intelligent material selection, competent engineering, a high degree of innovation and convincing design. The prize has been awarded since 2003 and addresses designers and engineers alike. eMove360° Europe 2018 is one of the world's leading technology trade fairs for sustainable mobility solutions.

  • Anellotech announces commercial plant engineering plans


    Sustainable technology company Anellotech confirms significant progress in its Bio-TCatTM technology development program

    mThe company has begun planning for scale-up design and engineering of a commercial plant with its process development and design partner IFPEN and commercialization, engineering, and licensing partner Axens.

    Anellotech is pioneering an innovative manufacturing process to produce cost-competitive renewable chemicals and fuels from non-food biomass. Its patented Bio-TCat thermal-catalytic technology produces a mixture of benzene, toluene and xylene (BTX) which can be used to make important polymers such as polyester, polycarbonate, and nylon, or high-octane gasoline blendstock. Jacobs, a globally respected engineering firm, recently confirmed that the Bio-TCat process enables a CO2 emission reduction potential of 70-90% when compared to petroleum-derived equivalents. Co-product gas streams from Bio-TCat can be used to make significant amounts of renewable electricity, hydrogen or cellulosic ethanol using third-party technologies.

    Commercially-viable process yields and catalyst performance has now been achieved at economic design conditions at Anellotech’s TCat-8 pilot unit in Silsbee, Texas. TCat-8 has demonstrated consistently stable operation of major process steps and recycle loops, with highly-accurate analytic confirmation. These attractive results have been achieved with real-world commercial feedstock, loblolly pine recently harvested from Georgia forests. Anellotech’s MinFree pretreatment process, operational at multi-ton scale, has been used to ensure low mineral content in the TCat-8 feedstock which is critical for catalyst performance.

    TCat-8 has operated for over 2,000 hours with continuous catalyst circulation including a fluid bed reactor, catalyst stripper, catalyst regenerator, quench tower, and recycle compressor. The pilot plant is operating mass balance closures of 100% +/-2%, and regularly completes uninterrupted 24/7 runs. The TCat-8 unit operates inside a commercial chemical facility that is OSHA PSM compliant.

    David Sudolsky, President & CEO of Anellotech, said, “Our TCat-8 unit consistently demonstrates stable, economic performance as we continue to further optimize process conditions. These advancements come from the dedicated and coordinated efforts of Anellotech, IFPEN and Johnson Matthey engineers and scientists. We are excited to begin commercial plant engineering activities with our partner Axens and open up engagement with potential partners for investments and locations for the first commercial plant.”

  • First home-compostable coffee capsule hits the market


    Leading packaging manufacturer ALPLA is announcing a breakthrough in the world of coffee capsules: a biodegradable Nespresso-compatible capsule that is suitable for home composting, developed in close cooperation with German materials expert Golden Compound.

    sMade from Golden Compound green, a non-GMO organic material incorporating ground natural fibres derived from sunflower seed shells, the new capsule and filter fleece are completely biodegradable in the garden compost within a maximum of six months. ALPLA supplies the capsule and the garden-compostable lid.

    The very first user is Amann Kaffee from Vorarlberg, Austria. The coffee roaster is presenting the new product as part of the ‘Gustav – fair for consumer culture’ trade fair in the Dornbirn trade fair district, October 19-21. Golden Compound will also be represented at the Fakuma trade fair for the plastics industry in Friedrichshafen (Hall B4, Booth 4114) from 16 October.

    Golden Compound uses sunflower seed shells as a reinforcing material. They are a by-product of the food industry and not in competition with food production. Composting the capsule generates humus, and the coffee grounds contain valuable plant nutrients such as potassium, phosphorus and nitrogen.

    The material also has excellent characteristics, as confirmed by numerous certificates: the oxygen barrier is very similar to conventional plastics such as PP-EVOH-PP. The monolayer coffee capsule is aroma-proof without outer packaging. Furthermore, Golden Compound green is certified in line with the standards ‘OK compost HOME’ and ‘OK biodegradable SOIL’ from TÜV.,
