The energetic valorisation of wastes through gasification is a promising solution with a better environmental impact in terms of pollutant emissions compared with incineration, landfilling, and heat and power generation from fossil fuels. However, techno-economic studies are imperative to define the viability of these technologies and to optimise heat and power consumptions and costs. This work intended to develop a techno-economic analysis for a small-scale gasification plant processing mixtures of solid recovered fuels and sewage sludge, assuming a capacity of 883 kg/h and two different sale scenarios: (A) production of electric energy, and (B) production of hydrogen. Gasification tests and mass and energy flow analyses were carried out for the economic assessment. The results showed that both scenarios presented viability for implementation. Although scenario A was more attractive in the short-term period due to the lower payback period (9 year) and higher internal rate of return (IRR, 7.5%), the other option was more favourable at the end of plant's life once the net present value was greater (1,801,700 €). Based on the results of a sensitivity analysis, a conclusion could be drawn that the economic indicators payback period and IRR were most influenced by capital expenditures applied in the plant.

与化石燃料的焚烧、填埋、热能和发电相比，通过气化对废物进行能量增值是一种很有前景的解决方案，在污染物排放方面具有更好的环境影响。然而，技术经济研究对于确定这些技术的可行性以及优化热量和电力消耗以及成本是必不可少的。这项工作旨在对小型气化厂处理固体回收燃料和污水污泥的混合物进行技术经济分析，假设产能为 883 kg/h 和两种不同的销售场景：(A) 电能生产，以及(B) 制氢。进行了气化测试以及质量和能量流分析以进行经济评估。结果表明，这两种方案都具有实施的可行性。尽管由于较低的投资回收期（9 年）和较高的内部收益率（IRR，7.5%），情景 A 在短期内更具吸引力，但另一种选择在工厂寿命结束时更有利，一旦净现值更高（1,801,700 欧元）。根据敏感性分析的结果，可以得出结论，经济指标回收期和内部收益率受工厂应用的资本支出影响最大。
