“…This is because pollutants that affect water, soil, and air are constantly released into the environment, producing many residues. One of the most critical industries that is essentially considered a source of water pollution is the dye industry, whose products are used in many applications such as textiles, paper and pulp, wood composites, cosmetics, soap, colored glass, paints, ceramics, polymers, adhesives, art supplies, beverages, wax, and biomedicines [ 1 , 2 , 3 ].…”

Today, the emphasis is on environmentally friendly materials. Alkali lignin and spruce sawdust are suitable natural alternatives for removing dyes from wastewater. The main reason for using alkaline lignin as a sorbent is the recovery of waste black liquor from the paper industry. This work deals with removing dyes from wastewater using spruce sawdust and lignin at two different temperatures. The decolorization yields were calculated as the final values. Increasing the temperature during adsorption leads to higher decolorization yields, which may be due to the fact that some substances react only at elevated temperatures. The results of this research are useful for the treatment of industrial wastewater in paper mills, and the waste black liquor (alkaline lignin) can be used as a biosorbent.

The pressing need to develop eco‐friendly polymer materials for building applications has led to increased interest in modifying existing polymer systems. In this study, a sustainable approach to augmenting urea‐formaldehyde (UF) resins, widely employed in wood‐based panels is introduced. Addressing this, formaldehyde‐scavenger demethylated lignin nanoparticles into UF resins, aiming to produce a green and enhanced medium‐density‐fiberboard (MDF) with minimal formaldehyde emissions is incorporated. The results indicate that increasing concentrations of demethylated lignin nanoparticles in the UF adhesive, there is not only a reduction in formaldehyde emissions from MDF composites but also a significant decrease in thickness swelling. The highest reduction in formaldehyde emission is observed in the MDF composite prepared with UF resin containing 7% lignin nanoparticles (UF‐7NL), with an emission of 2.9 mg/100 g, marking a substantial decrease of 74% compared to emission of 11.2 mg/100 g from neat resin. Importantly, this reduction does not compromise physical and mechanical properties of the MDF; they remain comparable to boards bonded with unmodified UF. Molecular modeling revealed that lignin effectively traps formaldehyde, incorporating it as ‐CH2OH groups, leading to a notable decrease in formaldehyde emission from MDF. This approach offers an eco‐friendly modification to a common polymer, showcasing lignin nanoparticles as innovative additives.
