DÜSSELDORF, GERMANY — DSM NV said its Arnitel Eco material can now be made with up to 73 percent bio-based content, thanks to a new butanediol deal with Genomatica Inc.
Frederic Petit, sustainability, communication and branding director at DSM, said the company is currently testing materials made with Genomatica's bio-based BDO. The bio source is currently rapeseed oil but Genomatica can use a variety of different raw materials, he said.
"Arnitel Eco is continuously evolving and now 73 percent can be bio-based, depending on the hardness of the materials," he said.
At K, DSM (Hall 6.1/N4) also is showing its Eco Paxx 410 material, which is derived from castor oil grown in India.
"This polymer was launched at the last K show but has now been commercialized with a lot of customers," Petit said.
Eco Paxx can also be used for non-automotive applications, for example sunglasses, which were designed by Italian company Nannini, and food packaging, made by development partner MF Fobien.
According to Petit, one of the major differences between K 2010 and K 2013 is the shift, in terms of bioplastics in any case, from biodegradable materials, to bio-based durable materials which can often be recycled at end of life.
"At the last K there was lots of PLA, now there are bio polyamides," he said.
