Abstract

In this paper, refuse derived fuels (RDF) produced on an industrial scale in the State of São Paulo (Brazil) were thoroughly characterized. Textiles, paper/cardboard and plastics represent the highest percentage of RDF composition, with the first two fractions being the main contributors to RDF biomass content, which ranges from 39 to 57 wt% on a dry basis (db). Moisture, volatile matter and ash contents range from 19.5 to 35.8, 65.4 to 79.6 and 14.4 to 29.1 wt% db respectively. Carbon content ranges from 43.2 to 53.5 wt% db. The chlorine content is low (0.2–0.8 wt% db) as well as the mercury content which is less than 0.38 μg/kg (db). The net calorific value ranges from 16.9 to 22.0 MJ/kg (db). RDF meet the classification requirements of European and Brazilian standards. Their characteristics demonstrate their potential as a fuel for various thermochemical processes. The use of RDF is therefore an opportunity for a more circular economy. The use of RDF as an alternative fuel in the cement industry brings both economic and environmental benefits. This study provides valuable information for decision-makers to better understand RDF and plan their use in Brazil.

巴西生产的垃圾衍生燃料：物理化学分析、标准和能源回收的机会

在本文中，垃圾衍生燃料（RDF）生产的工业规模在圣保罗州（巴西）彻底表征。纺织品、纸/纸板和塑料在RDF组成中所占的百分比最高，前两个部分是RDF生物质含量的主要贡献者，其干燥基础（db）从39%到57%不等。水分、挥发物和灰分含量分别为19.5% ~ 35.8%、65.4 ~ 79.6和14.4 ~ 29.1 wt% db。碳含量为43.2 ~ 53.5 wt% db。氯含量低（0.2 ~ 0.8 wt% db），汞含量小于0.38 μg/kg （db）。净热值范围为16.9 ~ 22.0 MJ/kg （db）。RDF符合欧洲和巴西标准的分类要求。它们的特性证明了它们作为各种热化学过程燃料的潜力。因此，RDF的使用为更循环的经济提供了机会。在水泥工业中使用RDF作为替代燃料具有经济效益和环境效益。这项研究为决策者提供了有价值的信息，以更好地理解RDF并计划其在巴西的使用。图形抽象

期刊介绍： The Journal of Material Cycles and Waste Management has a twofold focus: research in technical, political, and environmental problems of material cycles and waste management; and information that contributes to the development of an interdisciplinary science of material cycles and waste management. Its aim is to develop solutions and prescriptions for material cycles. The journal publishes original articles, reviews, and invited papers from a wide range of disciplines related to material cycles and waste management. The journal is published in cooperation with the Japan Society of Material Cycles and Waste Management (JSMCWM) and the Korea Society of Waste Management (KSWM).
