Abstract

The growing concern over environmental pollution from industrial dye effluents necessitates the development of sustainable and efficient treatment methods. Biochar, a carbon-rich material derived from agricultural residues, presents a promising solution for dye adsorption and agricultural waste management. This study highlights the properties of biochar that make it an ideal sorbent for dye adsorption and examines how feedstock quality, pyrolysis conditions, and surface characteristics influence the adsorption capacity. The studies demonstrate that biochar can efficiently remove various synthetic dyes from aqueous solutions, with adsorption depending on the surface area, pore size, and functional group. In addition to dye removal, the utilization of agricultural residues for biochar production offers dual benefits of waste management and environmental remediation. Biochar provides a cost-effective and eco-friendly alternative to conventional adsorbents, promoting circular economic practices. This paper offers a comprehensive analysis of biochar’s applications, benefits, and challenges in dye treatment and waste management, emphasizing its role in achieving sustainability.

可持续染料处理和农业废物管理的生物炭解决方案

工业染料废水造成的环境污染问题日益受到关注，因此有必要开发可持续的高效处理方法。生物炭是一种从农业残留物中提取的富碳材料，为染料吸附和农业废物管理提供了一种前景广阔的解决方案。本研究强调了生物炭使其成为理想染料吸附剂的特性，并探讨了原料质量、热解条件和表面特性如何影响吸附能力。研究表明，生物炭可以有效去除水溶液中的各种合成染料，吸附能力取决于表面积、孔径和官能团。除了去除染料，利用农业残留物生产生物炭还具有废物管理和环境修复的双重效益。生物炭为传统吸附剂提供了一种具有成本效益和生态友好的替代品，促进了循环经济的发展。本文全面分析了生物炭在染料处理和废物管理方面的应用、优势和挑战，强调了生物炭在实现可持续发展方面的作用。

期刊介绍： The Journal of Material Cycles and Waste Management has a twofold focus: research in technical, political, and environmental problems of material cycles and waste management; and information that contributes to the development of an interdisciplinary science of material cycles and waste management. Its aim is to develop solutions and prescriptions for material cycles. The journal publishes original articles, reviews, and invited papers from a wide range of disciplines related to material cycles and waste management. The journal is published in cooperation with the Japan Society of Material Cycles and Waste Management (JSMCWM) and the Korea Society of Waste Management (KSWM).
