Global economic development and continuous rise in the standard of living has led to resource depletion and increased per capita waste generation and, thus waste management issue becomes crucial. Sustainable development and circular economy require prominent technology for reducing the pace of resource depletion while producing alternatives to meet future energy demands. Municipal Solid Waste (MSW) is a potential source of interest for the recovery of either secondary raw material or to produce energy. At present, most of the MSW in waste treatment plants is converted into recyclable fractions called Refuse Derived Fuel (RDF) through the process of Mechanical Biological Treatment (MBT) with the aim of reducing environmental concerns and increasing its value. The focus of this review is to evaluate the importance of a thermo-chemical process for conversion of RDF into fuel and value-added products as well as evaluating applicability of this process in waste management sector and solid waste treatment. However, due to heterogeneous nature of RDF, investigation of co-pyrolysis behavior of RDF components as well as reaction mechanisms in both catalytic and non-catalytic reactions has been conducted. It has been observed that a high H/C, low O/C ratio and lower biomass content in RDF feed produces better quality products and decreases the dioxins emission during pyrolysis. Interactions of free radicals produced from polymer components with biomass greatly affect the product distribution. Chemicals derived out of RDF pyrolysis have been discussed and effect of various catalysts in enhancing oil yield and quality has been summarized. Catalytic pyrolysis with the use of P, Ni, Co, and Mo modified zeolite catalyst improves the quality of oil, and also the activity and catalyst lifetime. Different reactor technologies available for solid waste valorization have also been analyzed.

全球经济发展和生活水平的不断提高导致资源枯竭和人均废物产生增加，因此废物管理问题变得至关重要。可持续发展和循环经济需要卓越的技术来降低资源枯竭的速度，同时生产替代能源以满足未来的能源需求。城市固体废物（MSW）是回收次要原材料或生产能源的潜在来源。目前，废物处理厂中的大多数城市固体废弃物通过机械生物处理（MBT）的过程被转化为称为垃圾衍生燃料（RDF）的可回收级分，目的是减少对环境的关注并提高其价值。这篇综述的重点是评估热化学过程对于将RDF转化为燃料和增值产品的重要性，以及评估该过程在废物管理部门和固体废物处理中的适用性。然而，由于RDF的异质性，已经对RDF组分的共热解行为以及催化和非催化反应中的反应机理进行了研究。已观察到，RDF进料中的高H / C，低O / C比和较低的生物质含量可产生更高质量的产品，并减少了热解过程中二恶英的排放。由聚合物组分产生的自由基与生物质的相互作用极大地影响了产物的分布。讨论了RDF热解衍生的化学物质，并总结了各种催化剂在提高油品收率和质量方面的作用。使用P，Ni，Co和Mo改性的沸石催化剂进行催化热解可改善油的质量，并提高活性和催化剂寿命。还分析了可用于固体废物评估的不同反应器技术。
