The annual food and agricultural waste production reaches enormous numbers. Therefore, an increasing need to valorize produced wastes arises. Waste materials originating from the food and agricultural industry can be considered as functional materials with interesting properties and broad application potential. Moreover, using an appropriate magnetic modification, smart materials exhibiting a rapid response to an external magnetic field can be obtained. Such materials can be easily and selectively separated from desired environments. Magnetically responsive waste derivatives of biological origins have already been prepared and used as efficient biosorbents for the isolation and removal of both biologically active compounds and organic and inorganic pollutants and radionuclides, as biocompatible carriers for the immobilization of diverse types of (bio)molecules, cells, nano- and microparticles, or (bio)catalysts. Potential bactericidal, algicidal, or anti-biofilm properties of magnetic waste composites have also been tested. Furthermore, low cost and availability of waste biomaterials in larger amounts predetermine their utilization in large-scale processes.
每年产生的食物和农业废弃物数量巨大。因此，对废物进行增值利用的需求日益增长。食品和农业产业产生的废物材料可以被视为具有有趣性能和广泛应用潜力的功能材料。此外，通过适当的磁改性，可以获得对外部磁场快速响应的智能材料。这样的材料可以很容易地从所需环境中进行选择性分离。已经制备了具有磁性响应的生物来源的废物衍生物，并将其用作有效的生物吸附剂，用于分离和去除生物活性化合物以及有机和无机污染物和放射性核素，以及作为固定各种类型的（生物）分子、细胞、纳米和微粒或（生物）催化剂的生物相容性载体。还测试了磁性废物复合材料的潜在杀菌、杀藻或抗生物膜性能。此外，废物生物材料的低成本和大量可用性决定了它们在大规模过程中的利用。
