Royal DSM, together with its automotive component specialist partner KACO, has developed a lightweight multi-functional crankshaft cover in EcoPaXX, DSM’s bio-based polyamide 410, for the latest generation of diesel engines developed by the Volkswagen Group. EcoPaXX, a bio-based, high-performance long-chain polyamide, is made mainly from tropical castor beans.
This EcoPaXX cover incorporates integral seals in PTFE and liquid silicon rubber (LSR), as well as various metal inserts. It will be used on Volkswagen’s new MDB modular diesel engine platform, implemented across its Audi, Seat, Škoda and VW brands.

SIM-Drive Corporation, founded by Hiroshi Shimizu and based in Kawasaki City, Japan, unveiled the SIM-CEL on 27 March—the third prototype of an advanced all-electric car incorporating in-wheel motors that the company has developed since it was founded in 2009. SIM stands for Shimizu In-wheel Motor, and CEL stands for Cool Energy Link.
Rennovia demonstrates production of HMD from renewable feedstocks; enabling production of 100% renewable nylon-6,6
April 25, 2013
Rennovia, Inc., a privately held company that develops novel catalysts and processes for the cost-advantaged production of chemical products from renewable feedstocks, has successfully demonstrated production of hexamethylenediamine (HMD) from widely available, renewable feedstocks. Coupled with Rennovia’s previously announced renewable adipic acid, this enables for the first time the production of 100% bio-based nylon-6,6 from monomers derived from bio-renewable feedstocks using chemical catalytic technology.
Nylon-6,6 is used extensively in automotive applications, where it is especially prized for its heat resistance, enabling under-the-hood applications. Nylon-6,6 is also widely used in fiber applications, including textiles, carpet, technical fiber, and tire cord.
ISU study finds large potential for biobased materials in auto industry, but with challenges
December 16, 2012
A study by researchers at Iowa State University has determined that the automotive industry has a very large potential to utilize biobased materials. Their report, “Biobased Automobile Parts Investigation”, was developed for the USDA Office of Energy Policy and New Uses. Because SUVs and trucks have a large number of parts, the authors suggested, they are good candidates to be the vehicle types with the largest amount of biobased material on a part number basis.
To create the largest impact, the researchers concluded, emphasis should be placed on the largest producers of vehicles; the five largest producers of automotive vehicles in the United States are General Motors, Ford, Toyota, Chrysler, and Honda. However, they noted, there are also many challenges associated with the use of biobased parts in the auto industry.
