  • Pressure and heat no problem for new ECOZEN grade

    17.07.2018

    VELOX GmbH, a distributor of raw material specialities for the plastics, composites, additives and paint & coatings industries, and its long-term partner SK Chemicals Co. Ltd. (South Korea) present the next innovation for plastic packaging.

    mECOZEN HF is a newly developed bio-copolyester replacement for aluminum, glass or PET wherever heat and pressure resistance combined with transparency is required. The first customers have already started sampling the grades.
    ECOZEN HF has processing requirements similar to PET and can be used in the same injection-stretch blow moulding (ISBM) process.
    “However, the new grades by SK Chemicals perform perfectly in areas where PET can sometimes fail, such as in high temperature and high pressure applications,” said François Minec, General Manager at VELOX.
    “For example, PET is sometimes used to produce aerosol bottles. These bottles can often fail due to high residual stress and the low temperature resistance of PET, especially in the summer months when possible leakage is the result. ECOZEN HF offers an ideal alternative here.”
    In addition to its outstanding resistance to pressure, stress-cracking and high temperatures, ECOZEN HF is characterised by excellent transparency and easy processing. As a replacement for glass, e.g. in food packaging, it not only helps to reduce weight and transportation costs but can also be used to produce hot-fill containers without any need for an expensive PET heat-setting process or for crystallising the bottle or jar neck. Similarly, as an aluminum substitute in the cosmetics packaging industry, ECOZEN HF combines high pressure-resistance with design flexibility and transparency.
    Ecozen HF is totally miscible with PET in the recycling stream. It is available from VELOX in nearly all European countries.

  • 100% bio-based plastic bottle closer to reality

    16.07.2018

    Breakthroughs at Anellotech’s TCat-8 pilot plant advance work on 100% bio-based plastic bottle prototypes, affirming the company’s commitment to innovative production of cost-competitive renewable chemicals.

    Sustainable technology company Anellotech recently achieved new milestones at its TCat-8 pilot plant in Texas, thereby progressing its 100% bio-based bottle collaboration with global consumer beverage company Suntory.

    Anellotech’s TCat-8 pilot plant is using Bio-TCat technology, an efficient thermal catalytic process which converts non-food biomass feedstock material into BTX aromatics, a group of renewable chemicals identical to their petro-based counterparts. The first shipment of BTX has now been sent to joint development partners IFPEN and Axens for purification studies to make bio-paraxylene – the key aromatic chemical needed to make 100% renewable beverage bottles a reality. Bio-paraxylene from TCat-8 will be used to make renewable PET resin for prototype bottle manufacture and product testing.

    Since the announcement of a successful two-week continuous pilot plant trial in March 2018, over 1,200 hours of cumulative on-stream time have been achieved at TCat-8, while BTX has been generated for product testing and evaluation and process development data collected for future commercial plant design. Anellotech also continues to produce other aromatic products through its Bio-TCat process, including benzene and toluene. These can be used to make a range of bio-based polymers such as nylon, polycarbonates, acrylonitrile butadiene styrene (ABS) and industrial chemicals such as LAB (linear alkyl benzene), which is used in laundry detergents.

    David Sudolsky, President & CEO of Anellotech, said “Following our announcements earlier this year on process development and continuous operation, we are glad that significant progress continues at our TCat-8 pilot plant. We continue to move the technology towards commercialization, and shipping the pilot plant’s product for downstream evaluation is another major milestone. Having collaborated with Suntory since 2012 to advance development of cost-competitive bio-aromatics, we hope bio-based plastics made from our Bio-TCat process and a 100% bio-based bottle soon become a reality.”

    Anellotech CEO David Sudolsky will be talking more about these developments and Anellotech’s work in a 10.15am breakout session at the BIO World Congress tomorrow, Tuesday 17 July entitled ‘Renewable Chemicals Making Headway into New Materials and Consumer Biobased Products’.

  • Under development: Lignin-based aerogels with excellent insulating properties

    13.07.2018

    A consortium of researchers from, among others, the Technical University of Hamburg-Harburg (TU HH) has successfully produced lignin-based aerogels that were subsequently processed into highly porous insulation panels with excellent insulating properties.

    cAerogels are solid, highly porous materials with a low density and low thermal conductivity.
    A team led by the Professor Irina Smirnova at the TU HH has now developed an aerogel that is largely lignin based – pure lignin based panels are not feasible -, using lignin derived from residual wood and wheat straw.
    The lignin was extracted using two environmentally friendly treatment methods, based on Organosolv-and Aquasolv protocols.
    Using five different gelling strategies, the lignin was then coverted into aerogels. One of the most successful approaches led to the development of hybrid lignin polyurethane aerogels with tunable densities of between 50 and 250 kg / m3. The mass-related content of lignin is 78 percent; insulation boards made from this type of Aerogel reach a thermal conductivity of 24 mW / m K ;which significantly exceeds the insulating properties of polystyrene or Rockwool. Lignin-based resorcinol formaldehyde aerogels with a surface area of 500 m2/ g, and a wide range of adjustable properties look promising. The procedure has been scaled up in the pilot.

    At the end of the project, two spin-off companies from the TU HH will promote the market introduction of the material after the end of the project, manufacturing lignin and aerogels on a pilot scale for interested companies.
    The first is BioMP (www.thebiomp.de), a company with expertise in the field of hot water hydrolysis and production of lignin; the second, Aerogelex (www.aerogelex.com) manufactures various types of organic aerogels and offers lignin PU Aero gel plates for industrial testing.

    The project "material use of lignin: Nanoporous materials" was promoted by the Federal Ministry of food and Agriculture (BMEL) as the project carrier for specialist agency renewable raw materials e. V. (FNR). The final report is available on fnr.de 22018312 available at the grant number. On the project were in addition to the HH TU the Fraunhofer-Institute for chemical biotechnological processes (CBP), University of Vienna, the Bavarian Center for applied energy research and the company Dräger safety and Loick organic value substances involved.
