“…The liquid phase (slurry) has a very low dry matter content [14]. Therefore it has also a low energy density [12,21]. Meanwhile, the range of liquid manure from cattle varies from 4% to 13% and, from pigs, from 1.5%-12% dry matter content.…”

Abstract:Residues from animal husbandry are one of the major greenhouse gas (GHG) emission sources in agriculture. The production of biogas from agricultural residues can reduce GHG emissions through an improved handling of the material streams such as manure storage. Additionally, biogas can substitute fossil energy carriers in the provision of heat, power, and transport fuels. The aim of this work is to estimate the manure potential for biogas production in Germany under the consideration of the farm size of livestock production. In Germany, cattle and pig farming is of major relevance with more than 130,000 farms throughout the country. To unlock the biogas potential of manure, the low energy density of manure, depending on the dry matter content, needs to be considered, meaning that biogas installations need to be built close to the manure production on the farm site. This not only results in a high number of biogas plants, but also due to the wide range of farm sizes in Germany, a huge number of very small biogas plants. Small biogas installations have higher specific investment costs. Together with the relatively low methane yields from manure, costs for power generation would be very high. Co-substrates with higher methane yield can lower the costs for biogas. Thus, the use of a co-substrate could help to use small manure potentials. Biogas plants with the necessary minimum size of 50 kW el installed power could be established at farms representing 12% of all cattle and 16.5% of all pigs respectively in Germany. Using excrement from pigs, farms representing 16.5% of the total amount of pigs could establish a biogas plant. The use of manure in combination with energy crops can increase the size of biogas plants on a farm site significantly. At cattle farms, the share would increase to 31.1% with 40% co-substrate and to 40.8% with 60% co-substrate. At pig farms, the share would increase to 36% if co-substrates were used.

“…There are many methods of livestock waste disposal (Cantrell et al 2008), including composting (Tang et al 2006), anaerobic fermentation for methane (Maroušek et al 2015a), and heat treatment (Font-Palma 2012). Because the composition of livestock waste is complex (Shen et al 2015), the process time is long and the added value of products utilized is low (Maroušek et al 2015b), which results in low enthusiasm for farms. According to the study of Mardoyan and Braun (2015), when only taking into account of energy, biomass has a low economic efficiency for fuel.…”

The densification process of cattle manure (CM) and its combustion characteristics in air were studied under isothermal conditions. To be better aligned with practical applications, cotton stalk (CS) and corn cob (CC) were chosen in this paper as the controls. The stability of densified biomass briquettes under compressive force of 20 kN, 30 kN, 40 kN, and 50 kN were studied. Factors affecting the densification of biomass, including moisture concentration, densification pressure, and briquette size were studied, in addition to combustion conditions including heating rate and O2 concentration. The moisture concentration contained in the densified biomass briquettes were set at 5%, 10%, 15%, and 20%. The results showed a good stability of briquettes of CM (CM-B) under various densification pressures. The effects of moisture concentration on the combustion characteristics were small for CM-B. The influence of the densification pressure and O2 concentration on the combustion characteristics was a monotonic change. In summary, considering the stability and economy, 30 kN and 30% O2 concentration were judged to be favorable. The combustion characteristics of the CM-B did not monotonically increase with the size. The study's results showed that the CM-B could be used as a fuel under certain conditions.

Agricultural organic wastes (AOW) have the potential to provide bioenergy particularly found in biogas by anaerobic digestion (AD). In this study, the biogas production (BP) of AOW was obtained by batch AD with anaerobic digesters (500 mL) at 35°C incubator. The results showed that BP values in terms of volatile solids (VS) from rice husk, rice straw, flower residues, fruit and vegetable residues, wasted oyster shell residue (WOSR), fishery residues, livestock and poultry manures, livestock and poultry slaughter wastes (LPSW), and eight equally mixed wastes (EEMW) were 84.03, 193.36, 153.32, 76.27, 150.48, 63.26, 169.63, 615.74, and 172.83 mL/g VS, respectively. LPSW showed the highest μm of 16.99 mL/g VS‐d, the highest BP of 615.74 mL/g VS and the highest bioconversion efficiency of 65.98% compared to the other organic wastes. BP from the most AOW in Taiwan by AD was estimated to be 768,567,753 (743,522,223, excluding WOSR) m3/year. The annual BP of 768,567,753 m3/year of the eight total major AOW by AD was lower (∼20.11%) than 961,989,781 m3/year of the EEMW by anaerobic co‐digestion. Result also showed that modified Gompertz equation was suitable to describe BP accumulation and BP rate.
