Anaerobic digestion of poultry manure is a potentially-sustainable means of stabilizing this waste while generating biogas. However, technical, and environmental protection challenges remain, including high concentrations of ammonia, low C/N ratios, limited digestibility of bedding, and questions about transformation of nutrients during digestion. This study evaluated the effect of primary biological treatment of poultry manure on the biogas production process and reduction of ammonia emissions. Biogas yield from organic matter content in the aerobic pretreatment groups was 13.96% higher than that of the control group. Biogas production analysis showed that aerobic pretreatment of poultry manure has a positive effect on biogas composition; methane concentration increases by 6.94–7.97% after pretreatment. In comparison with the control group, NH3 emissions after aerobic pretreatment decreased from 3.37% (aerobic pretreatment without biological additives) to 33.89% (aerobic pretreatment with biological additives), depending on treatment method.

“…Regardless of the material used as a bed, moisture absorption increases as the substrates become denser due to the deposition of faecal solids 23 . Atmospheric conditions and collection forms also have an influence on moisture; litter stored outdoors in a waste pile had more than double the moisture content of litter collected from within the poultry house 30 . The ash content of PL is higher (10.9–21.7%) compared with other biomass such as woody biomass, the ash content of which is 2.2% 31 .…”

Poultry litter (PL) is one of the drier and bulkier manures produced in intensive agriculture. Land spreading is considered the most common treatment option for PL; however, this causes large atmospheric greenhouse emissions and consequently a high negative environmental impact. PL has several factors that limit its sustainable use as an energy source, and thus there is still a need for more studies about sustainable waste management. The paper aims at: (i) proposing sustainable pathways in order to maximise the PL valorisation process, based on previous experiences described in the literature; and (ii) showing the advantages of reforming poultry farms into biorefineries in Cuba. Combinations of techniques are used to increase PL valorisation, but only by modulating the theoretical data has an improvement occurred. In this work, pathways for thermo‐ and bioconversion processes are proposed which involve four major technologies for converting PL into useful energy and fertiliser, being pyrolysis/gasification, hydrothermal carbonisation and anaerobic digestion as key conversion technologies. Including technologies for nutrient recovery in the proposed pathways would allow better agricultural applications. The treatment of PL in biorefineries in Cuba would have a positive impact on the economy through income generation and savings resulting from reductions in imports (i.e. fossil fuels and agrochemicals), employment creation, improved living conditions and development in rural communities. Future studies should be aimed at evaluating the various proposed pathways in order to maximise the PL valorisation process, in addition to a marketing study of the products generated through the biorefineries at poultry farms. © 2020 Society of Chemical Industry (SCI)

The biogas production constitutes one of renewable energy sources (RES). In addition, wastes are preferred for energy production. In the case of some wastes, e.g. poultry manure, it is difficult to conduct anaerobic digestion in monofermentation. The aim of this work was to plan the biogas plant, in which the main substrate is the waste from a poultry farm. The scope of work included: preparation of a biogas plant technological project, determining the amount of biogas and methane that can be produced annually on the example of the selected poultry farm, performing the energy and financial calculations for the current conditions prevailing on the renewable energy market in Poland. The installation project assumed the location of a biogas plant at an existing poultry farm-the source of the substrate. The micro-biogas plant includes a fermentation tank with a capacity of 500 m 3 and storage of digestate pulp with a capacity of 700 m 3. The assumed power biogas plant will generate 112 kW of electricity and 120 kW of heat. The installation will operate in a single-stage mesophilic technology (39 ºC), which will avoid incurring additional costs related to heating and the construction of additional fermentation tanks. The use of poultry manure by anaerobic digestion provides benefits through biogas technology. It is necessary to examine the technology in terms of biogas production, which is carried out under better sanitary and environmental conditions. This work was undertaken to investigate the environmentally friendly removal of poultry manure through biogas technology to obtain the best economic effect, and employ it further, e.g. as a fertilizer.
