Abstract

Biowaste is a major source of organic material that can be converted into energy through various processes such as anaerobic digestion, composting, and pyrolysis. However, emerging pollutants, such as pharmaceuticals, pesticides, herbicides, and personal and household products, are a growing concern in wastewater treatment that can be effectively removed by biowaste-to-energy processes. While these contaminants pose significant challenges, the development and implementation of effective monitoring programs and risk assessment tools help to mitigate their impact on human health and the environment. Likewise, monitoring programs, challenges, legislations, and risk assessment tools are essential for understanding and managing the risks associated with emerging pollutants. Biowaste recycling is an important aspect of a biocircular economy perspective as it involves the conversion of organic waste into valuable resources that can be reused sustainably. The review discusses the modern approaches that offer several advantages, including reducing the waste disposal and generating renewable energy while addressing emerging wastewater treatment pollutants. To achieve the goal of a circular economy, modern biotechnological approaches including anaerobic digestion, composting, bioleaching, bioremediation, and microbial fuel cells offer a sustainable and effective way to convert waste into valuable products. These bioproducts alongside energy generation using waste-to-energy technologies can provide economic benefits through revenue generation, reduced waste disposal costs, and improved resource efficiency. To achieve a biocircular economy for biowaste valorization, several stakeholders, including waste collectors, waste management companies, policymakers, and consumers need to be involved. The sustainable conversion of biowaste to energy is an essential and instrumental technology in environmental sustainability.

以可持续的方式将生物垃圾转化为能源,以应对新出现的污染物:综述
生物垃圾是有机材料的主要来源,可通过厌氧消化、堆肥和热解等各种工艺转化为能源。然而,新出现的污染物,如药品、杀虫剂、除草剂以及个人和家用产品,是废水处理中一个日益令人担忧的问题,而生物废物转化为能源的过程可以有效地去除这些污染物。虽然这些污染物带来了巨大的挑战,但制定和实施有效的监测计划和风险评估工具有助于减轻它们对人类健康和环境的影响。同样,监测计划、挑战、立法和风险评估工具对于了解和管理与新兴污染物相关的风险也至关重要。生物废物回收利用是生物循环经济观点的一个重要方面,因为它涉及将有机废物转化为可持续再利用的宝贵资源。本综述讨论了具有多种优势的现代方法,包括减少废物处置和产生可再生能源,同时解决新出现的废水处理污染物问题。为了实现循环经济的目标,厌氧消化、堆肥、生物浸出、生物修复和微生物燃料电池等现代生物技术方法为将废物转化为有价值的产品提供了可持续的有效途径。在利用废物变能源技术生产能源的同时,这些生物产品还能通过创收、降低废物处理成本和提高资源效率带来经济效益。要实现生物废物价值化的生物循环经济,需要多个利益相关方的参与,包括废物收集者、废物管理公司、政策制定者和消费者。将生物废弃物可持续地转化为能源是实现环境可持续发展的一项重要技术。
