Wastewater

Introduction of foreign industrially produced organic (e.g., fatty acids and protein) and inorganic material (e.g., heavy metals) to water resources has become a global concern. In addition, the municipal waste effluents contain considerable concentrations of drugs and pharmaceutical products as well as detergents and dye pigments. We have generated lignin-based flocculants with superior functionality. Not only these products reduce the load of chemical use for cleaning wastewater effluent (and thus they produce less secondary sludge), but also they are biobased and generally reduce the use of synthetic oil-based products in water resources. In addition, the resultant sludge would contain lignin, which may have potential usage in the production of fertilizers and/ or animal feed mixtures.

Paint Industry

Paint and stain are vastly used in household and manufacturing facilities for decoration and protection. As solvent-based paint products are phasing out from the market, the need for the water-based formulation is enhanced dramatically. Our lignin-based products could be used for imposing various functionality to paint products. The natural aspect and great functionality of our lignin-based products make them great candidates for paint and stain products.
