Assessment of application of selected waste for production of biogas

Abstract

Abstract. Recently, the idea of biogas production has become a popular topic in Poland. Biogas is a valuable source of renewable energy with a potential application in electricity and heat production. Numerous types of technological solutions of biogas production are closely linked to the availability of substrates in the area, as well as their quantity and their properties. The paper presents the assessment of application in biogas production selected wastes such as communal and household sewage sludge and waste from a paper production in Opole region (Poland). The annual productions of methane, biogas and electricity were estimated. Chosen physico-chemical properties important in fermentation process were taken into consideration in the assessment. The highest value of potential energy was obtained using waste from the paper industry but the most appropriate parameters for this process has sewage sludge from the municipal sewage treatment plant. The use of sewage sludge from domestic and municipal sewage and waste from the paper industry creates the opportunity to reduce the amount of waste materials.

Waste Management in Dairy Cattle Farms in Aydın Region. Potential of Energy Application

“…Obtained energy parameters of manure is presented in Table 4. One of the key parameters in terms of the efficiency of biogas production is associated with the high content of organic matter in wastes, and this determines the course of the fermentation process and the volume of the biogas [21]. The tested samples have a high content of organic matter (74.62%), which is comparable with data obtained by Zue et al [48], it may range from 68% to 76%.…”

“…The average annual temperature is 17.6 °C, 26.77 °C in summer and 9.33 °C in winter. The composition of biogas is different and depends on the applied substrates; however, typically it consists mostly of CH 4 (40%-70%) and CO 2 (15%-60%), as well as other compounds in small amounts: H 2 O (2%-7%), N 2 (2%-5%), O 2 (0%-2%) < 1% H 2 , NH 3 (0%-1%) and H 2 S (0.005%-2%) [8,21].…”

The influence of temperature on algal biomass growth for biogas production

“…in medicine, pharmacy, cosmetology, food industry and agriculture [2]. Algae are also used in the sewage treatment process [3,4]. Results of studies indicate that it is possible to use algae-derived biomass as a source of organic matter in production of biofuels, including biogas ( Fig.…”
