Integral valorization of two-phase olive mill waste: extraction of cellulose and lignin and their characterization

The increased awareness regarding the economic and environmental impact of olive oil production waste has motivated a notable interest in reusing byproducts within the industry. By mitigating ecological risks associated with olive mill waste, this research addresses concerns about waste disposal and contributes to sustainable practices within the olive oil industry. This study focuses on extracting and characterizing two key biopolymers, cellulose and lignin, obtained from locally sourced two-phase olive mill waste. The development of a straightforward yet efficient extraction protocol yielded promising results, with 11.72
