“…Unfortunately, the comparison is still difficult, because the type of rearing system, composition of bedding material or the information on whether the material has been previously processed e.g., through pre-draying, are usually not specified. Parameters of the raw manure obtained from the cage system presented in Table 4 can be directly related to analyses of a battery-cage system located in Spain [26]. In both cases the moisture content M tw was found high, even above 70%.…”

Animal waste, including chicken manure, is a category of biomass considered for application in the energy industry. Poland is leading poultry producer in Europe, with a chicken population assessed at over 176 million animals. This paper aims to determine the theoretical and technical energy potential of chicken manure in Poland. The volume of chicken manure was assessed as 4.49 million tons per year considering three particular poultry rearing systems. The physicochemical properties of examined manure specimens indicate considerable conformity with the data reported in the literature. The results of proximate and ultimate analyses confirm a considerable effect of the rearing system on the energy parameters of the manure. The heating value of the chicken manure was calculated for the high moisture material in the condition as received from the farms. The value of annual theoretical energy potential in Poland was found to be equal to around 40.38 PJ. Annual technical potential of chicken biomass determined for four different energy conversion paths occurred significantly smaller then theoretical and has the value from 9.01 PJ to 27.3 PJ. The bigger energy degradation was found for heat and electricity production via anaerobic digestion path, while fluidized bed combustion occurred the most efficient scenario.

“…Members of the latter, Dethiobacter in specific, use sulfur compounds (thiosulfate and polysulfide but not sulfate) as electron acceptor, and short‐chain fatty acids and hydrogen as electron donors . This is not surprising as the chicken manure has elevated concentration of S due to the high requirement of S amino acids (methionine and cysteine) of the chicken . Dethiobacter spp.…”

BACKGROUND This study assessed the composition and dynamics of the bacterial and archaeal communities in a full‐scale two‐stage anaerobic digester over five months. The plant was fed on a variable mixture of feedstock, in which the energy crops were replaced with poultry manure/litter (from 1.6% to 7.5%) to reduce the operational costs. RESULTS The elevated concentration of ammonia in the digester did not hamper biogas production and its concentration of methane. The low level of acetate, butyrate and propionate in the methanogenesis phase indicated a strong activity of acetotrophic methanogens. PCR‐DGGE and sequencing have demonstrated that the stability of the volatile fatty acid distribution concurred with low level of population shifts as shown by the moving windows analysis. Nevertheless, PCoA analyses revealed that the variation in the digester alimentation and the carbon:nitrogen (C:N) ratio had a key role in assembly the bacterial and archaeal communities. The high ammonia level favoured the growth of Caldicoprobacteraceae and Syntrophomonadaceae, whereas dominant archaea detected belonged to the family of Methanosarcinaceae. CONCLUSION Cheap and readily available N‐rich feedstock could be used safely to decrease the costs of the anaerobic digestion process. © 2019 Society of Chemical Industry

“…The bomb calorimeter provided Higher Heating Value (HHV). The Lower Heating Value (LHV) was determined by using the HHV obtained from the bomb calorimeter including the hydrogen content and moisture of the waste components [8]. Equations (1) and (2) were used to determine the LHV of the waste samples:…”

a b s t r a c tRefuse Derived Fuel (RDF) was formulated from several municipal waste components in Singapore in order to maximize energy efficiency and minimize the environmental impacts. At first, the physicochemical properties (proximate and ultimate analysis, chloro, heavy metals) and the heating values of waste components were analyzed to assess their thermal behaviour. Three RDF prototypes were formulated by combining individual waste type in various fractions with respect to their properties and heating values. Landfill mining material and chicken manure were also involved in the RDF formation as alternative fuel sources. Optimum RDF was formulated consisting of 42% plastics, 41% paper/cardboard, 7% textile and 10% horticultural waste, based on the existing Singapore waste composition. This RDF had a lower heating value of 23.7 MJ kg À1 , which was less than mineral fuel but it could meet the fuel requirements given in the European standards. The addition of chicken manure and landfill mining material in RDF lowered the heating value and increased heavy metal concentration, but they are considered good alternative fuel. It is believed that power plants or dedicated incinerators could be potential endusers of RDF in Singapore.
