The Latvian State Institute of Wood Chemistry (, the main centre of wood science in Latvia, is an independent state non-profit organisation under supervisory of the Ministry of Education and Science Republic of Latvia. IWC is a research and innovation institute engaged in multidisciplinary applied and basic research and participating in academic education together with the largest universities in Latvia (University of Latvia, Riga Technical University and Latvian Agriculture University). IWC provides research in the field of wood and wood components chemistry and technology, polymer chemistry and biotechnology. The target of IWC is the development of scientifically grounded, environmentally friendly, waste less technologies based on biorefinery conception for obtaining of competitive materials and products from plant biomass. IWC has participated in 14 FP projects in EU, acting as coordinator in 3 of them. IWC is recognized as the Centre of Excellence (EC grant WOODPRO, the 5th FP and the grant WOODNET, the 7th FP).

Lignin Chemistry Laboratory at IWC (IWC LCL) (3 Dr. habil. Chem., 3  Dr. Chem., 6 PhD students, 6 M.Sc.) has an extensive experience in the detailed characterization of the structure, composition, physical properties and chemical reactivity of lignin in situ and isolated, using chemical and physico-chemical analytical methods as well as in development of lignin/lignocellulose raw materials processing methods including thermal, chemical and biochemical treatment. IWC LCL research group works in the areas of ecological friendly processing of reach-in-lignin by-products and waste from wood processing: design on the lignocellulose/lignin basis of active carbon sorbents, organomineral sorbents, biosorbents; design, testing and application of lignin and lignocellulose biologically active derivatives with controlled properties (bioactivity, protection function, complexing properties, sorption capacity, anti-oxidant activity); synthesis of lignin-based interface additives, flocculants, dispersing agents, flotation agents; modification of lignins/lignocelluloses residues from the lignocellulosic fuel ethanol production for obtaining of building blocks for bio-based composites. Production of fuel granules from lignocellulosic wastes, which correspond to requirements of commercial EU standards for solid biofuel, their co-firing with fossil fuels, combustion and emission characteristics of granulated solid biofuel are also investigated. In the area of utilization of plant biomass processing waste for environment objects cleaning, the IWC LCL works in collaboration with regional and EU countries research organizations, companies, SME and public organizations in EC, EUREKA! and bilateral projects.
