Arkema and bio-based products

Castor bean plant

In response to the dwindling supply of fossil resources, Arkema focuses its research efforts on renewable raw materials to produce green chemicals and bioplastics, which are more environmentally friendly.

Arkema's expertise in plant chemistry

Green chemistry, a priority research area for Arkema

Arkema has a unique know-how in the chemistry of the castor plant, a non-edible plant, from which a wide range of high-performance long-chain biosourced polyamides (Rilsan® polyamide 11 range) are produced. Many finished products are already made from these biosourced polymers: soles of sports shoes, eyeglasses, casing of cell phones, auto parts, etc.

Arkema R&D is exploring various opportunities in order to increase the use of renewable raw materials

Arkema’s R&D is exploring additional opportunities based on other plant species as raw materials:

  • Propylene, which is used to manufacture our acrylic acid essential for countless applications (pharmaceuticals, paper industry, paints, etc.), could be produced from glycerol, a polyol obtained from the production of biofuels made from rapeseed, sunflower or soya oil.
  • Cecabase®RT additives for road bitumen contain surfactants 50% made from raw materials of renewable origin. Their use helps reduce by up to 50°C the application temperature of road surfacing, and thus significantly save energy consumption compared to the standard process.

Bioplastics for automotive equipment

Supplier of castor oil, Arkema has an unsurpassed offering in bio-sourced polyamides.

On the strength of its expertise in castor oil chemistry, Arkema has developed a full range of ultra high performance biosourced polyamides capable of replacing metal in many under-hood applications.

 

In particular, Arkema recently developed the Rilsan® HT polyphthalamide (PPA) biopolymer used in the manufacture of certain under-hood equipment such as fuel lines, hydraulic lines, and connectors. This thermoplastic exhibits exceptional chemical and high temperature resistance, making it suitable to replace metal and rubber for the manufacture of rigid or flexible parts.

Collaborations to develop new plant-based raw materials

Alongside 17 European partners — businesses, agricultural institutes and universities —, Arkema is participating in the COSMOS research project, supported by the European Union and launched in March 2015.

The objective is to study the agro-industrial uses of camelina and crambe, two poorly known oilseed crops that cope with poor soil and can be harvested in just three months. They contain fatty acids that are not widely available in nature, potentially convertible into high-quality bioplastics.

Another major collaboration is Fiabilin in France, an R&D collaborative project overseen by Arkema and launched in September 2012. Its aim is to develop the use of flax in the manufacture of composite materials for a variety of markets, including automotive. Thanks to these vegetable fibers, manufacturers will be able to use high performance technical flax to replace glass fiber or carbon fiber as reinforcement for composite matrices.
