“…There are several reactions occurring simultaneously in the gasification process which are drying, pyrolysis, oxidation and reduction [36]. The first step of gasification is drying, in which the water leaves the coal particles in the form of steam [37].…”

“…These techniques constitute the process of biodegradable organic wastes. It is currently being practice in the palm oil industry and commonly applied in Malaysia due to cost-effectiveness and attractiveness of the method in relation to waste management and treatment [23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39].

Due to the emerging development in the energy industry, the demand for electricity consumption has sharply increased for each country. Therefore, a new recovery of energy resources is needed in consequence of the decreasing dependency on conventional energy resources, while sustaining energy security in the aspect of energy supply and climate change issues. The fuel cell is one of the most potential resources to be explored in order to overcome the constraints of the current energy generation. The aim of this paper is to discuss the entire cycle of the fuel cell system. It is starting from biogas production up to the recent studies related to life cycle assessment on fuel cell studies. Most of the researchers focused on the technical part of fuel cells; however, a comprehensive environmental assessment is essential to fully recognize the impact of fuel cells. Furthermore, this conceptual paper provided an idea on understanding the concept of fuel cell and referred to recently published articles related to life cycle assessment. Hopefully, this study can provide the guideline in determining the future energy for this country, in order to be less dependent on the current resources of energy supply.

“…Finally, LHV (d.w.) was not as high as expected because rejects contained a large amount of ash. Edo-Alcon et al (2016) [5] [36] reported an LHV of 23 MJ/kg (d.w.) and 10.5% ash (d.w.) for refuse-derived fuel pellets from rejects.…”

Behavior of Rejects from a Biological-Mechanical Treatment Plant on the Landfill to Laboratory Scale

et al. 2020

This paper describes the laboratory-scale simulation of the behaviour of rejects from a biological-mechanical treatment (BMT) plant in Castellón (Spain). For this purpose, four lysimeters were built, with different densities. Simulations were carried out for 7 weeks and leachate recirculation was applied to two of them. The experimental results allowed us to determine: (i) dirt in fractions, which was relatively high (up to 15% in some fractions) due to biological processes; (ii) the field capacity for this waste with similar values to other works, which varied depending on the experiment; (iii) variation in the biomass percentage which lowered after experiments in all cases (59.5% lower on average), and the rejects’ calorific value was higher after experiments (28.2% on average); (iv) the evolution of leachate properties with or without recirculation, where percolation, in addition to the dragging of soluble materials, stabilised waste, which diminished its biological activity. Rejects’ increased calorific value will allow combustible material to be recovered in the future as a way to exploit the energy potential stored in landfills.

“…Unfortunately, the price of this gas has also increased almost 3 times (0.21 EUR). Taking into account the calorific value of gas from the pyrolysis of RDF, which varies from 20 to even 30 MJ/m 3 [10,26,44,97], one can consider the use of pyrolysis gas for pre-heating furnaces before the plastic processing of metals [20]. Figure 13 compares the calorific values of conventional gaseous fuels with those of pyrolysis gas obtained from the pyrolysis of RDF.…”

The main goal of the study was to assess the possibility of practical use of products of pyrolysis of refuse-derived fuel (RDF), i.e., pyrolysis gas, biochar and pyrolysis oil, as an alternative to standard fossil fuels. The subject matter of the paper reaches out to the challenges faced by the global economy, not only in the context of the energy crisis, but also in the context of the energy transformation currently beginning in Europe. The increase in fuel and energy prices prompts countries to look for alternative solutions to Russian minerals. At the same time, the growing amount of municipal waste forces the implementation of solutions based on energy recovery (the amount of municipal waste per EU inhabitant in 2021 is 530 kg). One such solution is pyrolysis of RDF, i.e., fuels produced from the over-sieve fraction of municipal waste. In Poland, insufficient processing capacity of thermal waste conversion plants has led to significant surpluses of RDF (1.2 million Mg of undeveloped RDF in Poland in 2021). RDF, due to their high calorific value, can be a valuable energy resource (16–18 MJ/k). This issue is analyzed in this study.
