Abstract

This study investigates the adsorption capabilities of various biomass-based adsorbents for the removal of heavy metal ions from industrial wastewater. This research focusses on the comparative effectiveness of chemical and steam activation methods. Steam-activated adsorbents derived from wine sector waste exhibited a maximum adsorption capacity for Pb²⁺ ions of 399 mg/g. Adsorbents derived from walnut shells and chemically activated with HNO₃ ions exhibited a maximum adsorption capacity of 204.08 mg/g for Cu²⁺ ions. Steam-activated spruce sawdust adsorbents achieved optimal adsorption of Fe²⁺ ions at a capacity of 329 mg/g. The adsorption capacity for Cd⁺ ions was determined to be 116 mg/g, achieved through microwave-assisted steam activation of palm kernel shell-based adsorbents. The research emphasizes the necessity of selecting appropriate activation techniques based on specific heavy metal ions and the desired adsorption properties. Additionally, there is a necessity for further investigation into the processes of pore structure development and their impact on adsorption effectiveness. The findings suggest that developing adsorbent from biomass waste represents a sustainable and effective method for reducing heavy metal contamination in industrial wastewater, thereby advancing environmental protection and resource efficiency.

Abstract

Edible films serve as an effective barrier to prevent mass transfer between the product and its environment. This innovation facilitates the development of environmentally sustainable food packaging alternatives that promote the efficient use of natural resources. A variety of biopolymers are utilized in the formulation of edible films, primarily polysaccharides, proteins, and composite materials. Polysaccharides can be further categorized according to their origin, including plant, animal, marine, microbial, and industrial waste sources. Proteins are generally classified into plant- and animal-based categories. Composite films, which combine multiple biopolymer types, offer enhanced structural properties. The application of biopolymer-based edible films presents a promising strategy for mitigating commercial plastic waste accumulation. Nevertheless, the incorporation of additives—such as plasticizers, antioxidants, and antimicrobial agents—is essential to enhance film properties and ensure compliance with quality standards for food packaging application
