Environmentally friendly alternative for polystyrene
VTT Technical Research Centre of Finland is currently developing an affordable and environmentally friendly alternative for polystyrene from PLA bioplastic. The expansion of the bioplastic by foaming is carried out using carbon dioxide.
PLA products similar to polystyrene already exist, but their problem is their high price. In collaboration with companies operating in the field, VTT will be looking for new and more efficient production methods to enable the manufacturing of affordable products. VTT is also developing a process for PLA based on extrusion foaming, in order to replace polystyrene in traffic and packaging applications, for example (News Release VTT, 2 December 2014).
