Natural resource exploitation

This manuscript describes the dyeing properties of some textile materials using biological extracts from walnut and malt fungi. Also cellulosic materials were printed with colloidal metal nanoparticles obtained by reduction of metals by biological aqueous extracts. In the second part raw and modified biomaterials were used as adsorbents for carcinogenic dyes. Almond waste date waste and shrimp shell waste were used. In the final section nanoparticles were prepared from lignin extracted from poplar fibers and aqueous extracts of oleander pergularia and malta fungi plants and used for dye degradation.
