Review concerning enzymatic technologies for pulp and paper industry is presented in the article. Enzymes as additives for technological process provide selective destruction of different components and have positive effect on compositions of technological fluids, improving ecological safety of the factory.Enzymatic treatment (xylanases, cellulases, laccases, peroxydases) enhances lignin removing and decreases delignificating and bleaching agents dosage including chlorine-bleaching agents. Pitch removal with enzymes (lipases, laccases) provides destruction of pitch components. As a result removing of extractives destruction products and their bioconversion are more effective. Enzymatic deinking is alternative for chemical processes based on alkali, hydrogen peroxide, sodium silicate or chelates additives. Cellulases, xylanases, cellulases are recommended for these purposes.Microbiological monitoring of technological fluids and prevention of biofilms formation are perspective directions for industrial enzymes application. Enzymatic destruction provides obtaining low-molecular products and increasing bioconversion thereof.Based on the complex approach for technology realization (water recycling, quality of waste water treatment) enzymes are recommended for pollutants degradation and decreasing of waste water colour in the technological fluids. Enzyme preparations for waste water sludge utilization as a biofuel, compost and fertilizers are developed as well.Enzymatic analytic methods (peroxydase) provide highly-sensitive and selective detection of different substances in technological fluids.
