Member introduction

A sustainable world starts with the Separation processes. A world in which we can reduce our dependency on fossil fuels and minimize the impact we are having on our environment. We can prevent further depletion of our scarce natural resources, and create products and processes that can enable new low-carbon and resource-efficient industries to flourish, driving economic growth.

Many important manufacturing processes involve separation. It has been estimated that the costs resulting from separations account for up to 70 per cent of the process industry’s total cost. Laboratory of Separation and purification at Lappeenranta university develops more eco-friendly, energy and cost-efficient solutions producing less waste than ever before for the benefit of industry and society.

Their research includes examination of molecular interaction, unit operations and process concepts.  Our researchers study separation materials and their customisation, regeneration and re-use. An integral part of our research is centred on the optimal use of separation methods, synergies between different methods and the development of simulation and modelling tools.
