The objective of this study was to optimize the parameters for the development of refused derived fuel (RDF) pellets from municipal solid waste (MSW) and rice husk by using Response Surface Methodology (RSM). In this a systematic study was conducted, where three parameters were varied according to RSM factorial design. The binder concentration (5-10%) pressure (700-1200 psi) and retention time (3-7 minutes) were used for RDF pellet development under hydraulic press, measured hardness bulk density (BD) and durability (DU). The T 3 treatment results revealed the highest pellet hardness, bulk density, and durability 25 kg, 805 kg/m 3 , 99% respectively by application binder concentration (5%), pressure (1200 psi) and retention time (5 minutes). The experimental data on response variables were fitted into quadratic polynomial model using the multiple regression analysis and found that it was statistically significant quadratic model. The RDF physical chemical and mechanical characteristics were also evaluated and found their relationship between HHV, carbon, ash, DU, BD and energy density. The ash contents were inversely proportional to DU and HHV whereas DU was directly related to BD.

Pakistan is a developing country that is experiencing a shortage of electricity generation due to its rapidly growing demand. The existing and upcoming energy requirements for power generation and future transportation can be met by efficient utilisation of homegrown biomass resources. Determining the present energy mix resources in various sectors of the country is important. This article analyses the biomass resources and their potential and bioenergy utilisation in Pakistan. An overview of the global renewable energy scenario is presented. This article accentuates the importance and challenges of new technologies and estimates the current and future share of power generation from renewable sources, focusing on the technical potential of biomass energy, which is obtained from agricultural residues, animal manure and municipal solid wastes in Pakistan. This paper highlights the developing technologies that are primarily used to convert biomass waste into energy and presents a critical consideration on future directions in drafting the bioenergy framework policy in Pakistan. For effective implementation of biomass-based renewable energy production in the country, this paper presents an extensive literature review on current and future perspectives and suggestions on future directions and policies to overcome the deficit in electricity supply and environmental concerns. Furthermore, this paper discusses the utilisation of biomass resources in the rapidly growing transportation sector and presents a solution for upcoming mass transit projects in two major cities in Pakistan. The conclusion is that biomass energy is the most sustainable, eco-friendly and efficient renewable energy and is an emerging renewable energy resource that can meet the growing energy demand in Pakistan.

“…There are various technologies, such as thermochemical (e.g., gasification, pyrolysis) and biological (e.g., anaerobic digestion) conversion to convert MSW into energy (Rivard et al, 1995;Kwon et al, 2010;Panepinto et al, 2015;Seo et al, 2018). Of these two conversion platforms, thermochemical conversion could be more attractive because it is much quicker than biological conversion, and products derived from MSW can directly be used as a fuel or chemical feedstock (Ojolo and Bamgboye, 2005;Hlaba et al, 2016;Nandhini et al, 2022). However, either technology is suitable for some specific fraction of MSW (e.g., organics, plastics) where material recovery facility (MRF), a plant that separates various streams from the MSW, can play a significant role.…”

Because of accelerated urbanization and the development of a global economy, a large quantity of municipal solid waste (MSW) has been collected and disposed of by the municipalities. Due to this drastic increase in the disposal of MSW, the need for its management is a must to preserve the environment. Currently, approximately 50% of the total MSW generated in the United States has been utilized through various recycling, combustion, and composting technologies, which means the remaining 50% is sent to landfill; this is often known as non-recyclable MSW (nMSW). As this nMSW is physically and chemically heterogenous and contains very high amounts of inorganic material, processing is required prior to using it as a biorefinery feedstock. Thus, this study focused on how mechanical preprocessing advanced the physical and chemical properties of nMSW. The physical and chemical properties were investigated in terms of particle size distribution, bulk density, ultimate and proximate analysis, and the higher heating value (HHV). The combustion properties were examined in terms of ignition temperature, peak heat release rate, and combustion efficiency. Results showed that the variability of physical and chemical properties of nMSW can be reduced by mechanical preprocessing. For example, the variability of the bulk density of the as-received nMSW was approximately 17.3% while it reduced to 5.8% when the sample size was reduced to 2 mm. Similarly, the variability of ash and HHV reduced from 49.2% to 11.0% and 13.4%–4.2%, respectively. Combustion thermograms showed that the size reduction positively improved the combustion properties. For example, 2 mm of spec sample started to ignite approximately 4 times earlier and took 6.5 folds less time to reach the peak heating rate compared to as-received nMSW. Overall, the mechanical preprocessing reduced the variability of physical and chemical properties in addition to the improvement of combustion behavior of the nMSW which is one step forward toward the biorefinery feedstock.
