The scope of this paper is to examine the environmental and economic performance of an alternative household fermentable waste (HFW) management paradigm, developed within the framework of the HORIZON 2020 project Waste4think. In Greece, the business-as-usual scheme for the management of HFW is its disposal in landfills as part of mixed waste. Waste4think developed an alternative approach based on the benefits of source separation. Specifically, source separated HFW is taken to a drying/shredding plant, located in the municipality, for the production of a high-quality biomass product called FORBI. Alternative approaches have been examined for the exploitation of FORBI. In this work, the use of FORBI as an alternative fuel for the cement industry is assessed using life cycle assessment (LCA) and life cycle costing (LCC) tools. The results show that the proposed HFW management framework performs better than the baseline scenario both in economic and environmental terms. However, focus should be given to the optimisation of the drying/shredding process in order to reduce its energy intensity and environmental loadings.

本文的范围是检查在 HORIZON 2020 项目 Waste4think 框架内开发的替代家庭可发酵废物 (HFW) 管理范式的环境和经济绩效。在希腊，HFW 管理的常规计划是将其作为混合废物的一部分在垃圾填埋场进行处置。Waste4think 开发了一种基于源分离优势的替代方法。具体来说，源分离的 HFW 被带到位于该市的干燥/粉碎厂，用于生产称为 FORBI 的高质量生物质产品。已经研究了用于利用 FORBI 的替代方法。在这项工作中，使用生命周期评估 (LCA) 和生命周期成本计算 (LCC) 工具评估 FORBI 作为水泥行业替代燃料的使用。结果表明，拟议的 HFW 管理框架在经济和环境方面的表现都优于基线情景。但是，应重点关注干燥/粉碎过程的优化，以降低其能源强度和环境负荷。
