According to head researcher Prof Krijn de Jong: "The products are exactly the same [as petroleum-based ones], only they are made of pruning waste instead." The invention has already sparked the interest of the chemical industry, he added.
"Until recently, there were too many steps involved in the [biomass] process, so the technology was not efficient or economical enough to be used on a large scale," added de Jong.
"Industry will be able to utilise this technology to make bioplastics, biopaints and even biopharmaceuticals. The properties of these products are the same, despite the fact that the raw material is biomass instead of petroleum. The bioplastics are totally identical to regular plastics.
"In light of the imminent oil shortage, using sustainable raw materials is an extremely attractive option for industry," continued de Jong. "One major advantage of the method is that the raw materials are sustainable, but do not compete with the food supply, because they consist of wood-like biomass, such as branches, plant stalks and pruning waste."
The petroleum-free products are made using a catalyst consisting of iron nanoparticles measuring 0.00002 millimetres. The technology was developed in cooperation with Dow Benelux and Delft University of Technology.
