“…These fractions are the basic element of RDF production. Indeed, studies have been carried out in developed countries related to the use of RDF in cement kilns as an alternative fuel for petroleum coke have shown several economic and environmental advantages of this line of recovery [7][8][9][10][11][12][13][14][15][16][17][18].…”

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.

“…Both horizontal and vertical compressive strengths of our RDF were much higher than the reported values. It is noted that no binder was applied in this present study while cassava root stem and crude oil sludge were used as binders in Chiemchaisri et al [7] and Punin et al [14].…”

“…Therefore, the pressure of 21 kg/cm 2 gave the highest strength for plastic RDF production. Chiemchaisri et al [7] and Punin et al [14] indicated that the compressive strength of only 4.0-4.9 kg/cm 2 were sufficient for piling up in storage area and transportation with no or minimal damage. Both horizontal and vertical compressive strengths of our RDF were much higher than the reported values.…”

This work aimed to investigate the potential of plastic waste in old landfill as a resource to produce pelletized RDF. Old landfill contents at different ages of 4-5, 5-10 and over 10 years old were excavated and sorted. The combustible part consisted mostly of plastics at 34.0, 21.9 and 22.1% at younger to the older age in order. The non-combustible part composted of soil-like material from 63.8 to 76.3% which made up of daily cover soil and organic debris. High calorific value of the plastic waste of 33.11-43.41 MJ/kg was not diluted by the mixing of binder. Heated compaction method was used in the formation of RDF pellets in this study. Bulk density was linearly increased with higher compaction pressure (R2 = 0.9655). Besides, the vertical compressive strength of the formed pellets increased by 82 kg/cm2 when the compaction pressure changed from 7 to 21 kg/cm2 and started to decrease when it was above 21 kg/cm2. Meanwhile the horizontal compressive strength was rather stable and appeared independent of the compaction pressure. Calorific value of the RDF produced was high because no binder of lower calorific value was used, enabling it to meet the specified European standard for its calorific value.

“…Mechanical separation is most straightforward in the mechanical screening of MSW designed to maintain the low water content in the MSW [ 11 ]. Composting and stabilization of MSW can reduce high moisture content, while organic as the high carbon content is lost during the long-time consuming process [ 12 ].…”

This paper proposes novel wet-refuse-derived fuel (Wet-RDF) bio-drying process with the variation of initial organic substrate and moisture content. The bio-drying was carried out using 0.3 m 3 lysimeter aerated continuously at different rates. Two conditions of Wet-RDF feedstock tested included: Experiment A ‒ 37% organic substrate and 58% moisture content with an initial heating value of 2,889 kcal/kg; and Experiment B ‒ 28% organic substrate and 35% moisture content with an initial heating value of 4,174 kcal/kg. The bio-drying was performed in both experiments under negative ventilation mode and non-ventilation mode, the ventilation mode was set at the aeration rates of 0.2 m 3 /kg/day and 0.4 m 3 /kg/day. The results suggest that the optimum aeration rate was 0.4 m 3 /kg/day, achieving a 30% moisture reduction and a 60% heating value increase from their initial values. As a result, the improved wet-RDF qualified for the local cement industry’s standard in terms of heating value.
