“…The mineral composition of the pig dung showed variation across the different pig dung samples. The presence of sodium, potassium, calcium, zinc, copper, magnesium and total nitrogen in the pig dung is similar to the findings of Marszałek et al (2014) and Okoli et al (2019), they identified the presence of macro-minerals such as potassium, calcium, sodium, nitrogen, magnesium; trace minerals such as copper and zinc in pig dung. The total nitrogen composition in the pig dung was lower than the value recorded by Okoli et al (2019) but higher than the value reported by Marszałek et al (2014).…”

All the pig dung samples were considerably high in the potassium content, this is possibly due to high potassium content in the palm kernel cake and forage which constitute the bulk of their feed because it is cheap and readily available (Okoli et al, 2019).…”

Pig dung was evaluated for electric current and voltage generation using microbial fuel cell (MFC). Pig dung was collected from three different animal farms; FUTA, Air Force and Apatapiti Extension. Isolation and identification of microorganisms from pig dung was carried out before and after electric current and voltage generation using conventional techniques. Physicochemical composition were determined using standard methods. Microbial fuel cells (MFCs) chambers were fabricated. The circuit was completed with electrodes and flexible wires for electron transfer from the anode to the cathode. Pig dung was used as the anolyte while water was used in the cathode as the electron acceptor. Current and voltage were measured in the morning, afternoon and evening for 40 days using the digital multimeter. The result revealed sixteen microorganisms: Enterobacter cloacae, Escherichia coli, Shigella sp, Citrobacter gillenii, Klebsiella singaporensis, Paenibacillus septentrionalis, Bacillus circulans, Salmonella spp, Enterobacter asburiae, Yersinia intermedia, Yersinia enterocolitica, Fusarium sp, Aspergillus flavus, Aspergillus funmigatus, Aspergillus niger, and Penicillium chrysogenum. The highest bacterial and fungal population; 2.71 x 10 5 cfu/g and 1.47 x 10 4 sfu/g were observed from Air Force and FUTA pig dung respectively before current and voltage generation. The highest bacterial and fungal population; 1.35 x 10 5 cfu/g and 1.60 x 10 4 sfu/g were observed from Apatapiti Extension and FUTA pig dung respectively after current and voltage generation. The highest current and voltage; 0.319 ± 0.00 mA and 572.333 ± 3.84 mV were generated from Apatapiti Extension and Air-Force pig dung. Sterilized pig dung (control) generated a low voltage and current affirms the important role of microorganisms in voltage and current generation. In conclusion, pig dung can be used to generate electrical current and voltage owing to microbial activities present in the pig dung. A nuisance causing waste such as pig dung can serve as a renewable source of energy for electricity generation, this will simultaneously help to resolve the problems of environmental toxics that oozes from its disposal and ultimately serve as a way of mitigating global warming in the world.

“…Animal dungs contain nutrients which are detrimental to public health, but which can be used as biomass for fuel generation [14]. Pigs produce a huge amount of dungs that could be harmful to the environment if not properly managed [15]. Manure nutrients (total nitrogen and total phosphorus) found in Pig dung (PD) are considered the main source of environmental pollution [16].…”

This study is aimed at assessing the relationship between different anaerobic digestion parameters (biogas quality, retention time, pH, temperature, biogas pressure, volume of biogas produced and cumulative volume of gas produced) in a Pig-dung (PD) aided Water Hyacinth (WH) digestion process in order to maximize biogas yield in terms of quantity and quality. 25 - litre capacity plastic prototype digesters were used in the study and eleven (11) mix ratios of PD and WH were prepared namely: 10 WH: 0 PD, 9 WH: 2 PD, 8 WH: 2 PD, 7 WH: 3 PD, 6 WH: 4 PD, 5 WH: 5 PD, 4 WH: 6 PD, 3 WH: 7 PD, 2 WH: 8 PD, 1 WH: 9 PD and 0 WH: 10 PD. The digestion process was evaluated for a retention period of 40 days. A bivariate Pearson correlation analysis was carried out to examine the relationship between the quality of gas produced and other variables. The results revealed that daily gas production yields greatly improved in the co-digestion runs with mix 3 WH: 7 PD recording the highest maximum daily yield of 9.5 L with a cumulative gas volume of 140 L. For this mix, the methane content of the gas produced increased from 5.8% on day 4 to 69.2% on day 20. The least quantity and quality of gas was produced by mix 10 WH: 0 PD with a maximum daily yield 2.34 L and a cumulative gas yield of 32.18 L. The digestion of all the mixes occurred within a mesophilic temperature range of 28.2 to 31.4 0C and an increase in temperature within the digestion resulted in an increase in the quality of gas produced. The gas pressure ranged from 1 bar to 3.324 bars with an increase in gas pressure leading to a corresponding increase in volume of gas produced. The pH of the substrates ranged from 6.1 to 8.4 with the values low at the start of the digestion process and gradually increasing to its maximum at the end of the digestion process. The results revealed a very strong, positive and significant association between the quality of the biogas produced and other digestion parameters.
