“…compost. Its beneficial effects have already been proven in anaerobic reactors, as reported by Orrico Jr. et al (2016) and Haitl et al (2012), who used glycerin in the substrates and found greater breakdown of the solids contents during the digestion process, besides higher biogas and methane productions. Nonetheless, few studies are available on composting.…”

The composting of laying hen manure is an efficient way of treating waste and producing an organic fertilizer with excellent characteristics; however, the high N losses reduce its concentration in the resulting fertilizer. Associating this residue with crude glycerin (CG) promotes a better C:N ratio and contributes to higher N retention during composting, with improvements in solids reduction and production of organic fertilizer with higher concentration of this nutrient. We carried out this research considering the hypothesis that adding CG-a byproduct of biodiesel production-to laying hen waste composting provides better N retention in the fertilizer generated. Increasing CG doses (0, 3, 6, 9, and 12 % in relation to the fresh mass in the windrows) were added to the laying hen manure with windrows composted for 70 days. A reduction by 100 % in total and thermotolerant coliforms occurred at all levels of CG addition. The maximum reductions in total (TS) and volatile (VS) solids were 64 and 76 %, respectively, and occurred with the addition of 6 % CG. The windrows that did not receive CG had higher N losses during the process (32 %) while the highest N concentration in the compost was 5 % at 6 % CG. We identified that adding 6 % CG to the laying hen manure in co-composting increases the reductions in TS and VS and provides higher N retention, which improves the quality of the organic fertilizer.

“…Thermodynamic analysis is dealt with in the article (Chawla, Ghost 1992), where the calculation of parameters in generating hydrogen from biogas for fuel cells is described. Production of gaseous components in biofuel combustion is studied also in the work (Jandačka et al 2011;Haitl et al 2012). Usage of biogas as a fuel for combustion engines is described in the work of (Jablonický et al 2010).…”

Biogas production from other materials is examined in the works of (Haitl et al 2012;Janíček et al 2012;Zhang et al 2015) and others. Diversity, which is apparent in the biogas composition, can be also found in the methods of determination of the necessary parameters.…”

“…Biogas can be considered as a globally significant source of renewable energy that is produced by anaerobic fermentation of biological materials (Haitl et al 2012;Fodora et al 2013). At Slovak University of Agriculture in Nitra, a modern device for production of biogas from agricultural materials was developed and has been successfully used (Gaduš et al 2011;Janíček et al 2012).…”

Vitázek I., Klúčik J., Uhrinová D., Mikulová Z., Mojžiš M. (2016): Thermodynamics of combustion gases from biogas. Res. Agr. Eng., 62 (Special Issue): S8-S13.Biogas as a respected source of renewable energy is used in various areas for heating or in power cogeneration units. It is produced by anaerobic fermentation of biodegradable materials. The utilization of biogas is wide -from process of combustion in order to obtain thermal energy, combined heat and power production, gas combustion engines, micro turbines or fuel cells up to trigeneration. Biogas composition depends on the raw material. The aim of this paper was to develop a new methodology; according to this methodology, by means of gas mixture thermodynamics and tabular exact parameters of individual gaseous components, all the necessary thermodynamic and operating values of biogas composition were calculated. The mathematical model of biogas combustion was elaborated. For an accurate realization of calculation, a computing program was designed.

Bio fuels such as biogas and biodiesel attract increasing attention all over the world as a substitute or mixture for fossil fuels in automobiles. Transesterification is the process that is used for producing biodiesel which is accepted worldwide because of its efficiency. Transesterification is the process done for decreasing the viscosity of the vegetable oil. In this paper, we have used Transesterification of cottonseed oil to produce biodiesel. The cost of production of one liter of biodiesel from cottonseed oil is thrice the cost of the diesel per liter. The byproducts of Transesterification process are glycerol and methyl ester water-wash. Both of the byproducts are good source of Methanol content which can easily be converted into methane gas or Biogas (CH4). Also, the cottonseed from which the oil is extracted can be used for producing biogas. In this paper, the laboratory experiments for Integrating Biodiesel and Biogas Plants are studied quantitatively in detail. By integrating both biodiesel and biogas plant, it is a way of reducing the cost of biodiesel which can boost the use of biodiesel in future.
