Resumen
[es] Actualmente tiene un enorme interés industrial aquella biomasa de naturaleza lignínica por la posibilidad de aprovechamiento de las tres fracciones que la constituyen: hemicelulosa, celulosa y lignina. De entre estos componentes, la lignina es un biopolímero muy abundante que ofrece en la actualidad múltiples aplicaciones: en la fabricación de espumas de poliuretano, como precursor de fibras de carbono, como antioxidante en la industria cosmética, en la fabricación de composites con propiedades físico-mecánicas iguales o superiores al polímero original, etc. Por otra parte, estos residuos de naturaleza celulignínica, podrían ofrecer una alternativa al empleo de combustibles fósiles, al ser sometidos a procesos de combustión, pirolisis o gasificación, ofreciendo un enorme potencial por ser una fuente de energía de carácter renovable.

Among these components, lignin is a very abundant biopolymer that currently offers multiple applications: in the manufacture of polyurethane foams, as a precursor for carbon fibers, as an antioxidant in the cosmetic industry, in the manufacture of composites with physical properties -mechanics equal to or superior to the original polymer, etc. On the other hand, these wastes of a cellulignin nature could offer an alternative to the use of fossil fuels, as they are subjected to combustion, pyrolysis or gasification processes, offering enormous potential for being a renewable energy source. In this study, residual biomass materials such as pistachio peel, olive pit and oil pruning have been valued for their use as adsorbent material after activation by acid treatment.
