Agro-waste management through sustainable production of activated carbon for CO2 capture, dye and heavy metal ion remediation

In the previous years, activated carbons (ACs) derived from agro-waste have demonstrated excellent adsorption capability. Production of ACs using easy available and low cost agro-waste marks them as unique materials for several environmental applications including but not limited toCO2capture, dyes and heavy metal ion removal by adsorption etc. This review highlights the present scenario of available agricultural land, global agricultural production and generation of enormous agro-waste worldwide with their alternative management by producing value-added and applicable ACs as an adsorbent for environmental remediation instead of burning. This review specifically aims to support researchers by providing an all-inclusive overview of different aspects of agro-waste management with a perspective in AC preparation, characterization and its environmental applications such as CO2 capture, dye and metal ion adsorption for enhancing the pathways to clean air and water.
