The present study focuses on the production of an alternative fuel (AF) for the cement industry from a food residue biomass (FORBI) product, generated from pre-sorted household food waste (HFW). FORBI is generated by drying and shredding the fermentable fraction of HFW collected door-to-door in the Municipality of Halandri, Greece. The key physicochemical properties such as the net calorific value (NCV), and the concentration of heavy metals and chlorine are subsequently determined using well-established international standards (EN and ISO). FORBI is evaluated as a potential AF in terms of technical feasibility and environmental impacts. Based on the characterization, FORBI is classified as a non-dangerous waste according to EWC 20 01 08, European Commission Decision 2014/955. According to EN 15359, it is classified as category 3, 2, and 1 with respect to NCV, Cl, and Hg respectively. The study concludes that FORBI is a suitable candidate as a secondary fuel for the cement industry, given its high calorific value along with its low humidity and ash content. Challenges for practical implementation include the relatively high chlorine content, the inclusion of alkalis in the cement produced, and the reduction of non-thermal NOx emissions.
本研究专注于从预分选的家庭厨余垃圾（HFW）中产生的食品残渣生物质（FORBI）产品生产替代燃料（AF），用于水泥行业。FORBI 是通过在希腊哈尔兰德里市挨家挨户收集可发酵部分进行干燥和切碎而产生的。随后使用成熟的国际标准（EN 和 ISO）确定关键物理化学特性，如净热值（NCV）以及重金属和氯的浓度。根据技术可行性和环境影响评估 FORBI 作为潜在替代燃料的潜力。根据特性，FORBI 根据欧盟委员会第 2014/955 号决定，被归类为 EWC 20 01 08 中的非危险废物。根据 EN 15359，它在 NCV、Cl 和 Hg 方面分别被归类为第 3、2 和 1 类。该研究得出结论，鉴于其高热值以及低湿度和灰分含量，FORBI 是水泥行业二次燃料的合适候选物。实际实施面临的挑战包括相对较高的氯含量、水泥生产中碱的存在以及非热 NOx 排放的减少。
