Bioproducts, such as energy and fertilizers, are strongly interrelated with the biodegradable waste treatment processes, within a holistic management strategy. Although different forms of biological treatment technologies are available, anaerobic digestion represents a process of major importance in the overall management strategy of biodegradable waste. This paper presents a methodology to support decision making for efficient management of biodegradable waste. The decision support framework provides the background towards the selection and design of a biodegradable waste installation with emphasis on the recovery of energy and organic fertilizer. The discrete steps are analytically defined and illustrated to assist managers and policy makers to organize their decision making in the whole spectrum of procedures required to promote sustainable biodegradable waste management programs. The methodological approach developed can be generically applied by public authorities, producers and stakeholders following essential basic steps regarding safe and environmentally friendly production of high-quality final product. Moreover, a demonstration is performed for a real-case study for the Region of Serres, Greece. The proposed installation is expected to manage 3,285 t of biodegradable waste and generate approximately 160,000 m/a of biogas, 400 MWh/a and 450 MWh/a. The final bioproduct exceeds 3 kt of digestate that will be valorized in arable land close to the installation. Crucial interactions and managerial insights are also highlighted. The decision support framework aims to assist the research community, the private sector and decision makers to produce affordable and sustainable compost/digestate recovered from waste, also supporting the transition to a low carbon future and sustainable -circular- development.
生物制品，如能源和肥料，与可生物降解废物处理过程密切相关，是整体管理策略的一部分。尽管有多种形式的生物处理技术可用，但厌氧消化是可生物降解废物总体管理策略中的一个重要过程。本文提出了一种支持决策的方法，以实现可生物降解废物的有效管理。决策支持框架为可生物降解废物装置的选择和设计提供了背景，重点是能源和有机肥料的回收。离散步骤进行了分析定义并加以说明，以协助管理人员和决策者组织其决策，涵盖促进可持续可生物降解废物管理计划所需的整个程序范围。所开发的方法可以由公共当局、生产者和利益相关者普遍应用，遵循关于安全和环保的高质量最终产品生产的基本步骤。此外，还对希腊塞雷斯地区的一个实际案例研究进行了演示。预期该拟议装置将管理 3285 吨可生物降解废物，并产生约 160000 立方米/年的沼气、400 兆瓦时/年和 450 兆瓦时/年。最终的生物制品超过 3000 吨消化物，将在装置附近的可耕地中得到利用。还强调了关键的相互作用和管理见解。决策支持框架旨在协助研究界、私营部门和决策者从废物中生产负担得起且可持续的堆肥/消化物，也支持向低碳未来和可持续的循环发展过渡。
