“…The chemical composition and physical properties of sewage sludge are variable and depend on the type of wastewater being treated and the treatment processes used (Chalamoński & Szymczak, 2017). Sewage sludge is defined as the organo-mineral solid phase separated from wastewater or as a mixture of water and solid particles from various types of wastewater naturally or artificially in urban WWTPs (Ministerstwo Środowiska, 2018).…”

“…Although the presence of nitrogen, magnesium, and phosphorus in sewage sludge meets the needs of plants in fertilizers (Włodarczyk et al, 2014), nevertheless, the sludge may also contain dangerous toxic substances such as heavy metals in dissolved form, coprecipitated with metal oxides, as well as adsorbed or associated with biological residues (Ministerstwo Środowiska, 2018). Researchers have claimed that in recent years, the content of heavy metals in sludges has been decreasing (Chalamoński & Szymczak, 2017). At the same time, sludge contain-ing more than 90% dry weight can be disposed of thermally (Milik et al, 2016).…”

“…The sewage sludge is a potential fuel that needs to be properly processed so that the gasification process can be considered a promising way to produce heat and energy (Chalamoński & Szymczak, 2017). Thermal waste disposal in order energy generation, recommended in a feasibility study for several Polish cities and used in more than 400 waste incineration plants in Europe, is widely known, economically, and environmentally proven (Dziołak, 2010).…”

“…The possibility of using a mixture of sewage sludge with beech sawdust and sewage sludge with lignite was studied (Constantinescu et al, 2018); with wood waste, rapeseed and rye straw, pine bark, and coal in various mass ratios (Chalamoński & Szymczak, 2017) (Table 3). Although the production of energy from secondary fuels is economically feasible due to their lower price than fossil fuels, the high variability and instability of the quality of waste-derived fuels should be considered (Skawińska et al, 2017).…”

The sludge generated from wastewater treatment facilities contains high nutrients and is characterized by high heating values. Thus, the sludge enriched with organic matter and nutrients is a potential candidate for its application as fertilizers and an alternate energy feedstock. Nowadays, energy independence contributes to the economic stability of the country, and therefore the search for alternate energy sources is an acute issue. This paper presents a case study on using sewage sludge as an energy feedstock in Poland. The physicochemical characteristics of the sewage sludge are presented. The fuel properties of sewage sludge generated from different waste water treatment plant (WWTP) are summarized. The calorific value of sewage sludge generated in Poland is insufficient for effective use as an energy raw material, therefore, energy potential of mixture of sludge with other waste have been studied. The general trend of sewage sludge formation and the quantitative forecast for the future showed that in 2020, compared to 2012, sludge accumulation increased by 6.9%, but compared to 2019 - decreased by 3%. From 2012 to 2020 the average, sewage sludge accumulation increased annually by 0.8%. This demonstrates the heterogeneity of waste streams for the production of alternative fuels and a modest increase in sewage sludge production in the coming years. This made it possible to prepare several options for the further development of research in the field of developing technologies for obtaining alternative energy. Also this study will help the prospective researchers understand sewage sludge generation and its use as energy feedstock.

The construction of new wastewater treatment plants and the modernization of existing ones lead to the expansion of sewage networks, resulting in a sharp increase in the volume of municipal sewage sludge, which translates into a global problem of sludge management. The solution to this problem could be the recovery of energy from sewage sludge in the cement industry to exploit its energy potential. The aim of the present study was to examine the results of laboratory research on the production of alternative fuels based on municipal sewage sludge, plastic waste from end-of-life vehicles, and wood waste (sawdust) from carpentry enterprises. The tests were carried out for waste mixtures designated as PAZO I, PAZO II, PAZO III, and PAZO IV fuels, differing in the percentage of waste used and the type of plastic waste. The following parameters were evaluated in fuels: water content, ash content, sulfur content, and calorific value. Water content of the obtained fuels ranged from 17.1% to 19.4%, the ash content ranged from 2.5% to 3.4%, while PAZO II fuel was characterized by the highest ash content, which was 17.6%, but it remained within the limits permissible for alternative fuels.The sulfur and chlorine contents did not exceed the permissible values for alternative fuels. The calorific value of alternative fuels obtained was high and ranged from 16.5 MJ/kg to 33 MJ/kg. Furthermore, the composition of the individual fuel mixtures was selected to avoid energy-intensive sludge drying, whereas the fuel met the requirements for alternative fuels. The energy properties and water content of the obtained fuels indicate that the maximum amount of sewage sludge should not exceed 25% to maintain the parameters permissible for alternative fuels. Therefore, the analysis of the results leads to the conclusion that the obtained fuels, based on municipal sewage sludge, plastic waste, and wood waste (sawdust), meet the requirements for alternative fuels used in the cement industry. Today, the fuels based on municipal sewage sludge can be more of an alternative to conventional fuels used in the cement industry. The application of the fuels produced in the cement industry eliminates the formation of combustion byproducts in the form of slag and ash since they become a component of clinker. As an additional source of energy, the use of fuels in the cement industry will create an opportunity to move toward the circular economy.
