Lignin is a natural biopolymer found in the cell walls of plants. Kraft lignin, in particular, is a widely available by-product of the paper industry, to which we aim to add value due to its potential as a renewable resource. In this research line, we produce Kraft lignin nanoparticles using the antisolvent method and incorporate them into biodegradable polyvinyl alcohol (PVA) films. The goal is to enhance antioxidant activity, UV absorption, and hydrophobicity, creating functional materials for active packaging and industrial applications.
