Food waste represents a potential source to produce value-added materials replacing the use of virgin ones. However, the use of food waste as feedstock in biorefineries is still at an early stage of development and studies assessing its economic viability at large scale are lacking in the literature. This paper presents a techno-economic and profitability analysis of four food waste biorefineries that use wastes from tomato, potato, orange, and olive processing as feedstock. The study includes the assessment of potentially available quantities of those waste flows in Europe. Due to the low technology readiness level of this kind of biorefineries, a screening methodology to estimate the investment and manufacturing costs as well as two profitability ratios (the return on investment and the payback time) was adopted. Results show that not all the waste feedstocks have the same potential. The most profitable options are those related to implementing fewer plants, namely concentrating the production and capitalising on economies of scale while being at risk of increasing externalities, e.g. due to logistics of the feedstocks.
食物浪费是一种潜在的增值材料来源，可以替代原始材料的使用。然而，将食物垃圾作为生物炼制厂的原料的使用仍处于发展的早期阶段，文献中缺乏对其大规模经济可行性的研究。本文对四家以番茄、土豆、橙子和橄榄加工废弃物为原料的食物垃圾生物炼制厂进行了技术经济和盈利性分析。本研究包括评估欧洲这些废物流的潜在可用数量。由于这类生物炼制厂的技术准备水平较低，因此采用了一种筛选方法来估算投资和制造成本，以及两个盈利能力比率（投资回报率和投资回收期）。结果表明，并非所有的废物原料都具有相同的潜力。最盈利的选择是那些与建设较少的工厂相关的选择，即集中生产并利用规模经济，同时承担增加外部性的风险，例如由于原料的物流问题。
