Novozymes has launched its next yeast technology, Innova Lift, for the starch-based ethanol industry. Innova Lift expresses a glucoamylase that is two times more effective at converting difficult-to-reach starch. When paired with advanced enzyme solutions, Lift also has the potential to significantly increase ethanol yields, reduce fermentation risks and eliminate costly inputs, while improving performance reliability. Novozymes’ new yeast platform, Innova, has been founded on new S. cerevisiae yeast – utilizing proprietary methods to enhance its ability to withstand the rigors of today’s ethanol production processes and goals.

Covestro said that it is developing and marketing new polyether carbonate polyols, under the name cardyon. These polyols are produced with the aid of carbon dioxide (CO2). With Desmopan 37385A the company now offers the first representative of a new series of thermoplastic polyurethanes (TPU) containing polyether carbonate polyols based on CO2 technology.  Compared to conventional TPU materials, the new TPU products leave a lower carbon footprint and help close the carbon cycle. They also conserve fossil resources and, unlike many bio-based materials, do not compete with food production.  Desmopan 37385A has a hardness of 85 Shore A. Its mechanical properties are at least at the level of conventional TPU grades of similar hardness, and even exceed some of them. Read More

Perstorp said that it will expand the production capacity of its non-phthalate polyester plasticizer Pevalen from 2019 onwards. To achieve this the company has entered into a long-term production agreement with Italian company Alcoplast Srl. The new partnership more than doubles the current production capacity, bringing it in total to 50.000 tons per year and improving unit metrics due to the economies of scale. Pevalen (pentaerythritol tetravalerate or PETV) is Perstorp’s high-performance, true non-phthalate plasticizer. It is the perfect choice for sensitive applications and products in direct human contact, e.g. toys and childcare products, apparel and accessories, sports & leisure products, automotive interiors or other indoor applications such as furniture, floors or wall coverings in both homes and public spaces.
