Agricultural Waste and its Nano-Management: Mini Review

Abstract

A GRICULTURAL wastes are considered residues resulted during the agricultural production and after harvesting fruit and vegetable and their processing, agro-industrial by/co-products from the grapes, banana, olives and milk processing. These wastes may represent a treasure when they are turning into valuable applications (i.e., composts, biochar, adsorbents for removing pollutants from the environment and organic fertilizers) instead of burning it in open fields causing several environmental problems such as soil degradation and air pollution. The landfill disposal and open dumping of agro-wastes is a common practice in the developing countries generating huge amounts of ash, which may create serious health and environmental problems, primarily due to pollution of groundwater. Under the umbrella of the green bioeconomy and based on industrial innovation and high technology, new and better approaches for the recovery of agricultural wastes have been developed. This has contributed to guaranteeing sustainable production and its consumption, resource utilizing efficiency, the conversation of these wastes into valuable products and the reduction of negative environmental impacts.The common management of Agro-wastes may include a lot of suggested uses such as the production of biosynthesis of nanoparticles, biotechnological products, composting and biofuel production. Furthermore, a lot of bioactive compounds could be produced from the agrowastes, which have many application possibilities such as functional food, pharmaceutical and cosmetic approaches. The nano-management of agro-wastes may include using nanotechnology to convert the agro-wastes into a valuable product. This topic still has several open questions, particularly under sustainable and green bioeconomy prespective.

Ecofriendly remediation technologies for wastewater contaminated with heavy metals with special focus on using water hyacinth and black tea wastes: a review

“…Continued growth in this area requires improved performance with manageable costs to increase industrial profit margins. Agricultural wastes have received special attention because of their wide and abundant availability around the world (Thines et al, 2017 ; El-Ramady et al, 2020 ). Low-cost adsorbents can be effective materials for treating contaminated wastewater.…”

Exploitation of Sugarcane Bagasse and Environmentally Sustainable Production, Purification, Characterization, and Application of Lovastatin by Aspergillus terreus AUMC 15760 under Solid-State Conditions

“…It is just a small portion of it that is fed to ruminant cattle as roughage. However, these biomasses might promote the growth of microorganisms and the creation of biomaterials [ 1 , 40 ]. Additionally, the use of such materials in SSF by fungi in the pharmaceutical production of some key metabolites can reduce the use of dangerous chemicals that have a detrimental effect on the environment.…”

Additive-Mediated Phytoextraction of Copper-Contaminated Soils Using Medicago lupulina L.

“…Furthermore, studying the interactions between M. lupulina L. and contaminated soils at the molecular and microbial level can provide insights into enhancing metal uptake pathways and root exudates, improving remediation efficacy. The feasibility and effectiveness of additive-mediated phytoextraction under real-world conditions should also be validated by utilization different other types of additives like nanoparticles and biochar in laboratory experiments to field-scale applications (El-Ramady et al, 2020;Elramady et al, 2021;Singh et al, 2024aSingh et al, , 2024b. Finally, integrating phytoextraction with complementary techniques such as phytostabilization and bioremediation may offer sustainable land rehabilitation efforts synergistic benefits.…”
