“…Our results also indicated that using RDF has an environmental advantage. Reza, Soltani, Ruparathna, Sadiq, and Hewage (2013) investigated using RDF in two kilns in Metro Vancouver. They applied LCA and stated that using RDF in cement kilns can be an environmentally and economically viable solution for Metro Vancouver.…”

One of the techniques used to dispose of 4,000 tons per day (TPD) of non‐recyclable waste from Tehran is to burn it as an alternative fuel in cement kilns. This practice reduces emissions from landfills, prevents the loss of waste energy, and conserves fossil fuel resources. The aim of our study was to conduct a life cycle assessment (LCA) of clinker production in cement kilns using a combination of natural gas, mazut, a form of heavy, low‐quality fuel oil, and refuse‐derived fuel (RDF) from Tehran. We used SimaPro 7.1 software to perform an LCA of 1 kilogram (kg) of clinker produced using the following fuel combinations: the first scenario involved natural gas consumption alone, the second scenario involved a combination of natural gas and mazut, with the mazut providing 5% to 30% of the heating value needed to produce cement clinker in the kiln, and the third scenario involved a combination of natural gas and RDF (providing 5% to 30% of the heating needed in the kiln). The impact categories in the LCA of global warming, eutrophication, and acidification were assessed by the Center of Environmental Science of Leiden University (Centrum voor Milieukunde Leiden—CML) CML 2000 method. The results indicated that the third scenario, involving natural gas and RDF, reduced acidification by 2.14–11.5% and global warming by 0–1.3% relative to the first scenario involving the use of only natural gas. In addition, we observed a 0.65–3.81% reduction in acidification and a 0.9–3.8% reduction in global warming under the third scenario compared with the second scenario (co‐firing of natural gas and mazut). The amount of nitrogen oxides (NOX) emitted from the combustion of the Tehran RDF was greater than that was emitted when burning mazut. Therefore, reduction of nitrogen from the RDF composition is necessary. This study indicates that the use of Tehran RDF (with reduced nitrogen) in Tehran cement kilns does not increase cement kiln NOX, sulfur dioxide (SO2), and carbon dioxide (CO2) emissions; however, we need to conduct additional investigation into the chemical composition of the Tehran waste before using solid waste in place of fossil fuels.

“…Municipal solid waste management (MSWM) strategies have come into prominence for waste minimization, reusing, recycling, waste‐to‐energy, and finally landfilling. Thermal treatment or energy recovery is one of the most profitable MSWM strategies to attain clean and renewable energy from wastes . Metals, plastics, glass, paper, cardboard, and biowastes in MSW are separated from the residual fraction which is also called as reject fraction.…”

Burning behavior of fuel blends consisted of lignite samples and waste biomass species such as sewage sludge (SS) and refuse‐derived fuel (RDF) was studied. The blends where the wastes account for 5, 10, and 15 wt% were burned in a thermal analyzer up to 900°C. The nonisothermal burning kinetics were established using Borchardt and Daniels method that bases on the data obtained from differential scanning calorimetry. The maximum rate of combustion (Rmax), the peak temperature (TR‐max), the ignition temperature (Tign), and the burnout temperature (Tb) that predicts the thermal reactivity were considered to evaluate the effects of RDF and SS on the burning characteristics of the lignite samples. It was determined that the combinations of the additive behavior and the synergistic interactions govern the burning characteristics of the fuel blends. The thermal reactivity of the samples can be arranged in the order of RDF > lignite > SS. On the other hand, blending of RDF or SS with the lignite samples did not led to any significant segregation in the heat flow characteristics, and can be concluded that these wastes can be safely burned with lignite.

Effects of metal salt catalysts and gasification temperature on the gasification characteristics of combustible solid waste were studied, based on the source-classified waste in a fluidized bed gasifier, to provide guidance for utilizing the source-classified waste effectively. The results showed that the gasification characteristics of combustible solid waste, such as paper and sawdust, improved noticeably after adding NaCl, K2CO3, or sodium dodecyl benzene sulfonate (LAS). Adding NaCl to sawdust increased the yield of CO and CH4, while the gasification was inhibited gradually with increasing addition. Adding NaCl promoted the generation of H2 in paper gasification. NaCl played a catalytic role only when it exceeded a certain value. Adding K2CO3 increased the yield of H2 noticeably in sawdust and paper gasification. The catalytic effect of K2CO3 on sawdust was better than that on paper. Similar results were obtained for LAS in producing H2 in gasification. The carbon conversion efficiency and the gasification efficiency were increased with additional LAS. Moreover, the catalytic effect of K2CO3 was superior to that of LAS by comparison. As the temperature rises, the activity of the metal salt catalyst is enhanced, but it is inhibited if the temperature is too high.
