Use of waste lignin for modification of coniferous wood to increase fire resistance
Original language description
In current ecological and circular economy trends, emphasis is placed on recycling and innovative use of industrial waste materials. Waste black liquor from pulp production, rich in lignin, represents a significant material with ecological potential. This paper examines using of acidic and alkaline waste black liquors for wood impregnation to enhance its fire protection and optimize its properties. The analysis of total heat release showed that the impregnation of spruce wood with black sulphite liquor reduced the heat release to 19.14 MJ/kg and with kraft black liquor to 18.39 MJ/kg, representing a 6% decrease compared to the reference spruce (19.58 MJ/kg). Similar trends were observed for pine wood. Other parameters studied included wood surface properties, smoke production during combustion, and the ability of the wood to bind the liquor. The goal is to demonstrate that waste black liquors can be used without additional treatment, benefiting the wood processing industry, ecology, and supporting the principles of the circular economy.
