Sustainable Chemistry

The unit conducts diverse research for the utilization of inorganic by-products and waste streams. Research topics are related to water treatment, fertilizers and recovery of precious metals. New water treatment materials and chemicals are produced from suitable industrial by-products. Applications are adsorption, catalysis and precipitation. New recycled fertilizers are being developed from the nutrient-containing precipitates formed in water purification by combining them with nutrient-containing by-products. Industrial by-products can contain high concentrations of valuable metals, the recovery of which is studied in the unit.

The unit conducts research related to the utilization of lignocellulosic side streams as raw materials for high value-added products. The research topics include chemical modification of side streams to adsorbents and catalysts, conversion of side streams to platform chemicals as well as the preparation of biomass-based polymeric materials. Adsorbents and catalysts can be utilized in water purification; biomass-based polymeric materials, which have competitive and technically high-level properties, can be used to replace conventional fossil-based plastic materials.

High-quality research related to Li-ion batteries is conducted in the research unit. The main research topics related to battery chemicals are focused on cathode materials with high voltage and high energy density. These materials are suitable especially for electric vehicles. Sustainable anode materials including biomass-based graphite and Si/C composites as well as solid-state electrolytes are investigated. Recycling of used batteries are also researched.
