EPS i.e. Expanded Polystyrene is nothing but a waste product as it is utilized as packaging material and insulator all around the world. VTT, a technical Research Centre in Finland is working for development of a reasonable and eco friendly option for polystyrene from PLA bioplastic. PLA is a biopolymer made up of renewable materials using lactic acid. The research centre is looking for excellent methods for foaming the bioplastics in order to prepare beads which can be later subjected for refining into insulators. Although, EPS is a non toxic product but degrades into a waste product so it is important to replace it with some eco-friendly material. Burning of EPS is harmful as the compounds resulting from this process are health hazardous.

It is very important to consider the proper environment for foaming of bioplastics with the help of CO2. VTT is planning for introducing development of the product in industrial processing including lab work and factory testing. Thus, the research group wants new partners for a collaborative program in this direction and carrying out effective operations.
One more thing to know here is that PLA products similar to the polystyrene ones are in existence yet but they are costlier so VTT is looking for the idea for production of efficient and cheaper products.
