Abstract

The management of municipal solid waste (MSW) is a major obstacle for the majority of municipalities in developing countries because of the impacts related to the landfilling of waste. Garbage is an energy-rich material. As a result, energy recovery is considered to be a sustainable waste management method. In Morocco, 7.4 million tons are produced annually; most of the waste is landfilled without any recovery despite the impacts related to this method of disposal. The objective of this chapter is to characterize combustible fractions (RDF) from household waste in Morocco and to study the economic and environmental benefits of their use as alternative fuels in cement kilns. The results of this research show that the combustible fractions contained in household waste in Morocco constitute a potential sustainable energy source with a high lower calorific value (4454 kcal/kg). The study of the advantages of co-incineration shows that the substitution of pet coke by 15% RDF reduces the pollution linked to gaseous emissions. In addition, the cement plant can make financial savings 389 USD/h by minimizing the use of fossil fuels.

摩洛哥可持续固体废物管理:在水泥窑中共同焚烧RDF作为替代燃料

由于与垃圾填埋有关的影响，城市固体废物的管理是发展中国家大多数城市的一个主要障碍。垃圾是一种富含能量的材料。因此，能源回收被认为是一种可持续的废物管理方法。在摩洛哥，每年生产740万吨;尽管这种处理方法会产生影响，但大多数废物都被填埋，没有任何回收。本章的目的是描述摩洛哥家庭废物中可燃组分的特性，并研究将其用作水泥窑替代燃料的经济和环境效益。这项研究的结果表明，摩洛哥家庭垃圾中含有的可燃组分构成了一种潜在的可持续能源，具有较高的低热值(4454千卡/公斤)。共焚烧的优点研究表明，用15%的RDF代替pet焦炭可以减少与气体排放有关的污染。此外，通过减少化石燃料的使用，该水泥厂可以节省389美元/小时的资金。
