Green Chemistry

Clean water is essential not only to ensure life, but also to facilitate functional processes in many fields of industry. Research into purification techniques applies the principles that help in decreasing the use and creation of harmful materials during the design, manufacture and application of chemical products.

The LUT School of Engineering Science researches and develops different methods for the treatment of waste water, raw water and process streams. E.g. a new type of oxidation developed at the LUT saves 70 per cent more energy than traditional ozonisation.

Our key research topics include particularly challenging waste water treatment processes that are used in the pulp and paper, mining, food and pharmaceuticals industries' applications. Some examples of these applications are waste and raw water purification, recovery of chemicals from branch currents and efficient recycling of process waters in a closed water cycle.

Our research focuses on the energy-efficient utilisation of separation techniques, chemical analytics and issues related to water treatment, such as the minimising of water consumption. Additionally, we are researching the possibility of utilising materials based on microtechnology and nanotechnology in the development of purification methods.

Our aim is to develop more eco-friendly materials and methods for researching the status of the environment, as well as to solve problems related to the environment and industrial processes.
