Developing an environmentally friendly alternative for EPS

While it is used all over the world as packaging and insulation material, EPS (expanded polystyrene) is a problem as waste. This is why VTT Technical Research Centre of Finland is currently developing an affordable and environmentally friendly alternative from PLA bioplastic.
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 packaging applications (News Item VTT, 2 December 2014).
