“…The obtained process kinetics parameters for a batch based on sorghum are favorable. However, those parameters are lower values the an obtained for single substrates: maize silage and beet pulp [23]. Biogas production described by the Tabasarana model in this case for maize silage and beet pulp was higher and amounted to 677 and 649 Nm 3 /t VS.…”

Abstract:The research concerned the elaborate of non-waste biogas production technology based on the development of digestate from anaerobic digestion. In the anaerobic digestion process, the substrates of plant origin in the form of silage were used. The digestate obtained after biogas production was processed using the ORTWED method into a valuable granulated organic-mineral fertilizer, which contains a solid fraction of digestate, calcium and biogenic elements. This method can be successfully applied in agriculture in the context of its sustainable development due to the growing problem of utilization of digestate forming in agricultural biogas plants.

“…In this case, the following vibrations should be described: deformation CH groups (~1370 cm −1 ); defor- Corn bran enables a much higher yield of biogas and biomethane than the most popular maize silage in Europe. The content of methane in biogas from bran does not differ from the values from the literature [43], but despite a similar concentration of methane in biogas-at the level of 50-55%, the production of methane from silage per fresh mass is in the range of 170-220 m 3 per Mg [44][45][46][47]. This is much less than from corn bran (285-343 m 3 Mg −1 ).…”

The article presents the research made on the effects of methods of pressure-thermal agglomeration of corn bran, as well as the influence of processing parameters on selected physicochemical properties and biogas efficiency. Corn bran moistened to four levels of moisture content was used for the tests: 20%, 25%, 30% and 35% of dry matter. The pressure-thermal treatment was carried out with the use of a Brikol SJ25 pellet maker and a TS-45 single-screw extruder. In the tests of the extrusion-cooking process, three rotational speeds of the extruder screw were applied: 70, 90 and 110 rpm. The following characteristics were examined: efficiency of the extrusion-cooking and pelleting process, as well as the energy consumption. The water absorption index (WAI), the water solubility index (WSI), bulk density, kinetic strength, structure analysis by the ART/FTIR method, energy potential and the efficiency of cumulated biogas and cumulated methane per dry mass, as well as fresh mass and fresh organic matter and a series of microscopic pictures were completed. The analysis of the ATR/FTIR infrared spectra of the tested pelleted and extruded samples showed clear changes at the molecular level. Biogas production of extruded corn bran increased by several percent, as compared to untreated material.

“…Maize silage is a widely used raw material to ensure stable methane fermentation in 2 of 16 biogas plants and a high yield of biogas [11]. With one ton of corn silage with a content of 30% to 40% of the dry matter, 170-220 m 3 of biogas with a content of 50%-55% methane can be obtained [12][13][14]. For cultivars of maize for biogas in Poland, variety of FAO (Food and Agriculture Organization of the United Nations) 250 are recommended [15].…”

The effect of mechanical pre-treatment of nine different agricultural substrates minced to particle sizes of 1.5 mm, 5 mm and 10 mm on biogas and methane yields and fermentation kinetics was investigated. The results showed, that for five of the nine tested substrates (grass, Progas rye, Palazzo rye, tall wheatgrass, beet), a higher biogas production was obtained for the degree of fragmentation of 10 mm compared to fragmentation of 5 mm and 1.5 mm. For fragmentation of 5 mm, the highest biogas production was achieved for sorghum silage, Atletico maize and Cannavaro maize-649.80, 735.59 and 671.83 Nm 3 /Mg VS, respectively. However, for the degree of fragmentation of 1.5 mm, the highest biogas production (510.43 Nm 3 /Mg volatile solid (VS)) was obtained with Topinambur silage. The modified Gompertz model fitted well the kinetics of anaerobic digestion of substrates and show a significant dependence of the model parameters H max (biogas production potential) and R max (maximum rate of biogas production) on the degree of substrate fragmentation.
