Polyester sport and functional textiles treated with Sanitized® Odoractiv 10 are protected against “permastink”. Already a holder of the Swiss Technology Award, the Sanitized® Odoractiv 10 odor-management technology can now carry the bluesign® sustainability label, the Skin Friendly certification from the Hohenstein Institute and the ECO PASSPORT by OEKO-TEX® label. SANITIZED AG has been a bluesign® system partner for over 10 years. Odor-free Polyester Functional Clothing   An unwelcome odor can quickly develop in polyester sport and functional clothing, even if freshly washed. This is “permastink”. It’s a challenge to the textile industry as it generally reduces the attractiveness and market opportunities of sport and functional clothing made from polyester. The patented, non-biocidal Sanitized® Odoractiv 10 technology provides specific solutions and sales arguments for the end products. It works in two ways: The odor-causing bacteria can’t stick to the tex...

Nestlé and Danimer Scientific has announced a global partnership to develop biodegradable bottles. Nestlé and Danimer Scientific will collaborate to design and manufacture bio-based resins for Nestlé’s water business using Danimer Scientific’s PHA polymer Nodax™ .

Gevo has announced that it has developed a proprietary, breakthrough catalytic process that transforms low-cost commercially available, or even waste by-product, renewable alcohols into renewable isoprene that would be expected to compete head-to-head on price with natural and petroleum-based chemical equivalents while reducing CO 2 emissions. Key Chemical Building Block for Producing Rubber Isoprene is predominantly used in the production of synthetic-based rubber. The market for isoprene is estimated to be approximately $4 Billion USD by 2025, growing at a compound annual growth rate of 7% or greater driven by growth in the automotive sector. Chemical-based Catalytic Process Gevo recently developed a chemical-based catalytic process to convert low-value “fusel oils,” a mixture of alcohols that are byproducts from fermentation processes such as ethanol production, into renewable isoprene. Fusel oils from the ethanol industry alone equate to about 2.5 mil...

Children living in homes with all vinyl flooring or flame-retardant chemicals in the sofa have significantly higher concentrations of potentially harmful semi-volatile organic compounds (SVOCs) in their blood or urine than children from homes where these materials are not present, according to a new Duke University-led study. Higher Concentration of PBDEs in Children’s Blood Serum The researchers presented their findings Sunday, Feb. 17 at the annual meeting of the American Association for the Advancement of Science in Washington, D.C. They found that children living in homes where the sofa in the main living area contained flame-retardant polybrominated diphenyl ethers (PBDEs) in its foam had a six-fold higher concentration of PBDEs in their blood serum. Exposure to PBDEs has been linked in laboratory tests to neurodevelopmental delays, obesity, endocrine and thyroid disruption, cancer and other diseases. Vinyl Flooring Leads to Metabolite Concentrations...

Recently, polymer chemists from the University of Groningen, led by Prof. Katja Loos, have described an enzyme-based polymerization method to produce PEF, an alternative to PET, which can be made from bio-based furan molecules. Polyethylene terephthalate (PET) is one of the most successful plastics the material we use to make bottles and fibers for clothing. PET is used to make fizzy drink bottles because it has excellent barrier properties, which keeps the fizz inside. However, PET is made from petroleum-based building blocks. "But furan-based polymers are a good alternative", says Prof. Katja Loos. Furans, which are characterized by an aromatic ring with four carbon and one oxygen atom, can be made from biomass-derived sugars, and polymerized into Polyethylene 2,5-furandicarboxylate (PEF) . This alternative to PET, polyethylene furanoate (PEF), can be made from bio-based furan molecules, but to polymerize these furans you need toxic catalysts and high tem...

One thing that became apparent at the IAA Commercial Vehicles 2018 was that the issue of hydrogen tank approval had yet to be resolved. Though it had already been said years ago that tanks “must only get approved,” the process is taking much longer than expected. At present, there are few 700-bar type IV units for sale in Germany. The key reason for the lack of products seems to be that European automakers have not made a firm commitment to purchase tanks in large quantities for their vehicles. So far, OEMs have been ordering only few units for testing or integration into prototypes. At the same time, they have been demanding a lot from the manufacturers of those tanks, for example, by restricting the space in which units could be installed.  Tank manufacturers in Europe are deeply frustrated about the entire situation. Circumstances will not permit them to ramp up production capacity and make their business economically viable, so they are waiting to get products a...

Dr Henry Leung from the School of Chemical and Life Sciences and his team of three final-year students from the Diploma in Medicinal Chemistry found a way to lessen the environmental impact of coffee waste. They have turned used coffee grounds into a flame retardant that could potentially be used to improve fire safety in homes and offices. Leveraging Slow-burning Properties of Coffee By treating coffee waste and mixing it with epoxy resin – a material commonly found in floorings and walls of homes – the team were able to leverage the slow-burning properties of coffee to create a material that could withstand a fire by as much as two times that of regular epoxy resin. This new material has also attained an “HB” grading, which indicates slow burning on a horizontal specimen, based on initial findings by a third-party testing laboratory. Apart from its fire-resistant qualities, the coffee-epoxy resin has the potential to become a total solution for reducing coffee waste as groun...
