Braskem, Amyris & Michelin Collaborate to Develop & Commercialize Renewably-sourced Isoprene

Amyris, Braskem and Michelin announced recently that Braskem is joining a collaboration already launched in 2011 between Michelin and Amyris. This collaboration was initiated to develop and commercialize renewable isoprene, sourced from various biomass as an additional sustainable pathway to produce isoprene.
Under the terms of the agreement, Braskem, Michelin and Amyris will work together to develop a technology to utilize plant sugars, such as those found in Brazilian sugarcane or cellulosic feedstocks, to produce renewable isoprene. Adding the expertise of Braskem, the largest petrochemical company in the Americas and one of the global leaders in the production of biopolymers, Amyris and Michelin will accelerate the industrialization of renewable isoprene.
Amyris will share its rights to commercialize the renewable isoprene technology developed under this collaboration with Braskem. Michelin will maintain certain preferential, but not exclusive, access to the renewable isoprene to be produced by this technology. The companies will not disclose details of the agreement, including the financial contributions of each party.

This joint project, with Amyris and Braskem, will give Michelin an additional sustainable sourcing channel for poly-isoprene for the production of quality tires, providing a high-performance, environmentally responsible material.
“With this new partnership, we join forces with Amyris and Michelin in the development of an innovative technology that strengthens our commitment to improve people’s lives, creating solutions through sustainable chemistry,” said Luciano Guidolin, Vice President for Polyolefins and Renewables of Braskem. With a proven track record in leading research in sustainable chemistry, Braskem has already an experience in the development of 100% renewable polyethylene.

“Braskem is an ideal partner to join our isoprene project with Michelin. They bring the right expertise and share in our commitment to transform the chemical industry through sustainable product innovation and superior performance,” said John Melo, President & CEO of Amyris. “Amyris has led the way in producing long-chain hydrocarbon molecules via fermentation, from anti-malarial drug precursors to long-chain hydrocarbon molecules used in cosmetic emollients and even fuels. Building on the success of this proven technology to produce tailored hydrocarbons, we are revolutionizing the way products are made, one molecule at a time,” concluded Melo.

“We are pleased to have a strong industrial partner join our ongoing collaboration with Amyris. Braskem’s chemical industry experience, coupled with Amyris’s biotechnology expertise, will support Michelin’s goal of addressing the long-term needs of the tire industry for sustainable sourcing with renewable chemicals,” said Jean-Christophe Guerin, Head of the Materials Division of Michelin.

DSM Unveils Dyneema Purity® Radiopaque UHMWPE Fiber for Devices Used in Orthopedic Trauma

DSM, among the global leaders in biomedical materials science and regenerative medicine, announced the launch of its Dyneema Purity® Radiopaque fiber, one of the radiopaque ultra-high-molecular-weight-polyethylene (UHMWPE) medical fibers in the world. The fiber is the newest addition to DSM's medical Dyneema Purity® fiber portfolio.
Dyneema Purity® Radiopaque fiber is designed to support the development of medical devices for use in orthopedic trauma. The fiber contains a radiopacifier, which makes it the only UHMWPE fiber currently available that is visible in x-ray images. This feature helps surgeons with medical device and implant visualization both during and after surgical interventions.

The fiber will initially be used as a replacement for metal surgical cables that are used in procedures to treat bone fractures. The fiber is 15 times stronger than steel but maintains high pliability and increased flexibility, which may help lower the risk of bone damage. Steel does not conform well to the natural contours of the human body. A small contact point between the bone and metal wire leads to high levels of pressure in a concentrated area during surgery. On the other hand, UHMWPE fibers conform directly to complex bone anatomy, which increases surface contact and spreads force more evenly, reducing the risk of the cable cutting into the bone. The fiber is biocompatible and chemically inert, which can help reduce tissue inflammation, irritation and complications associated with metal allergies. All of these factors can increase patient comfort and promote shorter healing times.

UHMWPE fiber has additional advantages for cable construction. If a steel cable is wrapped around portions of a bone that require repairs, both ends of the cables must be guided through a tensioning device. Once fixation is complete, no incremental adjustments are possible and a re-adjustment can only be accomplished by cutting the cable and starting all over again. In contrast, a cable construction made from UHMWPE fiber promotes more flexibility and allows for re-tensioning after primary fixation without the need to start from scratch.
"With its impressive durability, flexibility and X-ray visibility, our Dyneema Purity® Radiopaque fiber gives device manufacturers the opportunity to use UHMWPE fiber in new applications," said Carola Hansen, Director of Biomedical Polyethylenes, DSM Biomedical. "Creating quality and innovative materials that help patients and surgeons is of the utmost importance to DSM."
"As an orthopedic surgeon, I have firsthand knowledge of the current challenges presented by traditional, steel cable solutions," said Professor Dr. Lodewijk van Rhijn, head of the department of orthopedic surgery at the University Hospital Maastricht, The Netherlands. "DSM's new Dyneema Purity® Radiopaque fiber has high flexibility which has the potential to reduce the chance of patients suffering from neurological damage. Further, the radiopacity would allow me to check instrumentation stability using x-ray imaging." Dyneema Purity® Radiopaque fiber is available worldwide.

AIDC to Produce Composite Panels for Airbus' A320 Family Aircraft Aft Belly Fairings

Aerospace Industrial Development Corporation (AIDC) in Taiwan has become a new tier-one supplier for Airbus. Under the agreement, which followed a thorough evaluation process, AIDC will produce composite panels for A320 Family aircraft aft belly fairings. The contract was signed by Fran├žois Mery, Airbus Senior Vice President Aerostructure, Procurement and Tony Liou, AIDC Senior Vice President.

The Airbus A320 Family is one of the world's best-selling single aisle product lines. As of end July 2014, the A320 Family had accumulated over 10,900 firm orders, with more than 6,100 aircraft delivered. The latest version A320neo, featuring new engines and Sharklets, has already gathered 3,200 orders before even entering service.
To date, 83 Airbus aircraft have been ordered by airlines in Taiwan, including China Airlines, EVA and TransAsia Airways, with 67 in operation. As among the leading aircraft manufacturers, Airbus seeks to explore further collaborations with industries in regional markets and to considerably grow its industrial presence, especially in the fast-growing Asia-Pacific region.
