The soaring prices of crude oil have sparked a debate about the benefits that increased use of renewable raw materials might bring to plastics production. Another aspect is the greater environmental compatibility attributed to products based on natural components. Industrial sugars and vegetable oils have been used for some time now in the production of polyols - one of the two basic components in polyurethanes alongside isocyanates. Bayer MaterialScience has developed polyols based up to 70% by weight on renewable raw materials to help cut down emissions.
