Abstract

Anaerobic digestion constitutes a sustainable method for waste management and renewable energy generation, addressing significant environmental and societal challenges. The growing global waste crisis and the increasing momentum toward sustainable energy solutions emphasize the critical need to enhance anaerobic digestion technology for improved efficiency and environmental advantages. This process mitigates waste accumulation, enhances energy security, and reduces greenhouse gas emissions, providing a feasible solution within the framework of a circular bioeconomy. Here, we review the principles of anaerobic digestion and biogas production, focusing on agricultural waste and the utilization of biogas for energy within a sustainable framework. We specifically explore biogas applications in rural and industrial settings, assess the environmental impacts, and discuss the regulatory landscape with insights from China and Europe. This study reveals that the strategic implementation of anaerobic digestion can markedly improve energy yield and sustainability, demonstrating how focused policies and advanced technological practices can optimize biogas utilization. The review enhances comprehension of environmental impacts, emphasizing insights from China and Europe as key examples.

厌氧消化农业废弃物以生产沼气和实现可持续生物能源回收：综述

厌氧消化是一种可持续的废物管理和可再生能源发电方法，可应对重大的环境和社会挑战。全球废物危机日益严重，可持续能源解决方案的势头日益强劲，这突出表明迫切需要加强厌氧消化技术，以提高效率和环境优势。这一工艺可以减少废物堆积，提高能源安全，减少温室气体排放，在循环生物经济的框架内提供可行的解决方案。在此，我们回顾了厌氧消化和沼气生产的原理，重点是农业废弃物和在可持续框架内利用沼气作为能源。我们特别探讨了沼气在农村和工业环境中的应用，评估了对环境的影响，并结合中国和欧洲的经验讨论了监管环境。本研究揭示了厌氧消化的战略实施可显著提高能源产量和可持续性，并展示了有针对性的政策和先进的技术实践如何优化沼气利用。本综述以中国和欧洲为例，强调了对环境影响的理解。

期刊介绍： Environmental Chemistry Letters explores the intersections of geology, chemistry, physics, and biology. Published articles are of paramount importance to the examination of both natural and engineered environments. The journal features original and review articles of exceptional significance, encompassing topics such as the characterization of natural and impacted environments, the behavior, prevention, treatment, and control of mineral, organic, and radioactive pollutants. It also delves into interfacial studies involving diverse media like soil, sediment, water, air, organisms, and food. Additionally, the journal covers green chemistry, environmentally friendly synthetic pathways, alternative fuels, ecotoxicology, risk assessment, environmental processes and modeling, environmental technologies, remediation and control, and environmental analytical chemistry using biomolecular tools and tracers.
