The issue of food waste is a significant global concern, with an estimated 1.3 billion tons of edible food lost or wasted each year, accounting for approximately one-third of the total food produced. Additionally, the presence of agricultural by-products, such as those generated during processing, poses a significant challenge in terms of environmental pollution and economic inefficiencies. This issue is particularly prominent in high-production regions like Asia and Australia. This study proposes an approach for utilizing this material by creating bio-adsorbents from agri-food and processing waste such as peels, grain husks and spent coffee grounds which are normally thrown away. These specialized bio-adsorbents will be developed to effectively eliminate water contaminants such as heavy metals, dyes and per- and polyfluoroalkyl substances (PFAS), which are persistent pollutants commonly found in water sources. Our primary focus is on the physicochemical characterization, development, and utilization of these bio-adsorbents with the goal of offering a highly efficient, economical and environmentally friendly approach to water purification. This approach not only tackles waste disposal concerns, but also provides a practical remedy for environmental pollution. By developing the concepts of the circular economy for agri-food waste, and improving waste management techniques, our study advances global sustainable development goals.
