“…The biogas produced is valuable waste from sludge disposal and is of outstanding quality. Since substrates are obtained for free while protecting flora and fauna against harmful effects of wastewater, biogas plants at sewage treatment plants are the best solution for biogas production [40]. Biogas production in wastewater treatment plants (WWIPs) plays a decisive role in reducing CO 2 emissions and energy needs in the context of the waterenergy nexus [41][42][43][44][45].…”

The study aimed to assess the most efficient solution of raw material management in selected biogas plants into the concept of circular economy and evaluate the most efficient solution of raw material management in selected biogas plants due to the quality and quantity of the feed and the final product obtained, which is biogas, as well at the closed circulation (circular economy). The study evaluated two agricultural biogas plants on a real scale and one at the sewage treatment plant (in real scale) in northeastern Poland. A year-long study showed that in technical terms, the best work efficiency is achieved by agricultural biogas plants processing: silage, manure, apple pomace, potato pulp (biogas plant No. 1), followed by biogas plant No. 3 processing chicken manure, decoction, cattle manure, poultry slaughterhouse waste (sewage sludge, flotate, feathers), and finally, the lowest efficiency biogas plant was No. 2, the sewage treatment plant, which stabilized sewage sludge in the methane fermentation process. Moreover, based on the results, it was found that agricultural biogas gives the best efficiency in energy production from 1 ton of feed.

“…66, No. 9 (2023) authors used the granite in different sources as powder waste from sawing processes of ornamental stones, fresh and weathered rocks in the ceramic tile industries and concluded that about 15-40 % of granite can be used for the production of red stoneware tiles using rapid-firing cycles and fired at 1200-1300°C [18][19]. Granite is considered a flux material due to its large amount of alkali oxides as K2O and Na2O.…”

Alkaline-granite was added on the ceramic bodies sintering at different temperatures from 1140 O C to 1200 O C. Four batches (50/50, 60/40, 70/30, 75/25) of granite to clay ratio were designed to investigate the effect of the granite/clay ratio on the phase composition and densification parameters. Mineralogical and chemical composition of the starting raw materials was evaluated using XRD and XRF, phase composition, densification parameters, and microstructure of the fired batches were studied. The densification parameters decrease as increasing granite ratio and decreasing of clay. For the effect of the temperature, the bulk density, porosity, and water absorption decrease with increasing of the firing temperature, in batch no 1 and 2. Batch no 3, bulk density and linear shrinkage decrease, while apparent porosity and water absorption increase. Batch no 4. Bulk density and linear shrinkage decrease, apparent porosity and water absorption slightly increase till 1180 o C and decrease at 1200 o C. XRD and SEM with EDAX confirm that quartz and mullite are only two phases were detected. Feldspar was totally replaced by alkaline granite in the formation of vitrified ceramic tile masses. Alkaline granite is better sintering behaviour it reduces the verification temperature and decreases the water absorption from 1140 to 1200 o C. In the production of ceramic tiles, whitener of the fired product is not a required parameter; the substitution of feldspar for alkaline granite can be more beneficial due to the relatively higher cost of feldspars.

“…The stages of acetogenesis and methanogenesis responsible for the production of methane, called "methanogenic fermentation", are also related [21]. Hence, there is often a reference to a two-stage process of anaerobic conversion of organic matter [22]. The fermentation process functions best when the rate of decomposition of organic matter in the acidic and methane-fermentation stages is the same.…”

This paper presents an analysis of selected parameters of biogas, formed as a result of methane fermentation, during the start-up of a biogas installation, using water, liquid manure, corn silage and inoculated sludge as substrates. Moreover, the dependencies between the type and amount of the supplied substrate and the obtained parameters of biogas and fermentation mass are presented and explained. During 59 days after the start of the biogas plant operation, the methane content increased to a maximum of about 62%. Finally, after about 80 days, the methane content stabilized at a constant level of about 55%. CO2 content increased from about 6% (day 32) to about 46% (day 84), with a clear linear correlation between carbon dioxide and methane content. Oxygen content decreased from about 18% (day 32) to about 0.3% (day 84) as the resulting gases displaced air from the reactor, and there was also a linear correlation between oxygen and methane content. The hydrogen sulfide content decreased from about 76 ppm (day 32) to about 0 ppm (day 47), after which, in a clear power correlation to the methane content, it maximally increased to 890 ppm (day 61). However, for the sake of safe engine operation, the desulfurization plant was started on day 63, which resulted in a H2S concentration below 50 ppm on day 74 of the experiment. The final hydrogen sulfide content was 9 ppm on day 84 of the biogas plant start-up.
