“…Raposo et al (2009) observed stable digestion operation for TVFA/TA ratio in the range of 0.30-0.40 or less but at around TVFA/TA ratio of 0.70 destabilization of digester was observed. Similarly, Islam et al (2012) noticed TVFA/TA ratios as important criteria for judging stability in batch digesters during anaerobic co-digestion of food waste with SM. The VS removal for FW was found to be 77.3% which is similar as reported by Eiroa et al (2012) but lower than as reported by Chen et al (2010) (81%-95%) (Appendix 1).…”

Purpose:The biogas productivity potential of fish waste (FW) was evaluated. Methods: Batch trials were carried out in 1.3 L glass digesters kept in a temperature controlled chambers at 36.5˚C. The first order kinetic model and the modified Gompertz model were evaluated for biogas production. The Chen and Hashimoto model was used to determine the critical hydraulic retention time (HRT Critical) for FW under mesophilic conditions. The feasibility of co-digestion of FW with animal manure was studied. Results: The biogas and methane potential of FW was found to be 757 and 554 mL/g VS, respectively. The methane content in the biogas produced from FW was found to be 73% and VS removal was found to be 77%. There was smaller difference between measured and predicted biogas production when using the modified Gompertz model (16.5%) than using first order kinetic model (31%). The time period for 80%-90% of biogas production (T80-90) from FW was calculated to be 50.3-53.5 days. Similarly, the HRT Critical for FW was calculated to be 13 days under mesophilic conditions. The methane production from swine manure (SM) and cow manure (CM) digesters could be enhanced by 13%-115% and 17%-152% by mixing 10%-90% of FW with SM and CM, respectively. Conclusions: The FW was found to be highly potential substrate for anaerobic digestion for biogas production. The modified Gompertz model could be more appropriate in describing anaerobic digestion process of FW. It could be promising for co-digestion of FW with animal manure.

“…While 6% to 8% increase in feed concentration decreased the conversion efficiency and at 10 % inhibition of the process occurred. Alike study of Islam et al (2012) also reported the methane production from food waste and its co-digestion with swine manure at 35 o C analyzing various feed to inoculum (F / I) ratios and food waste to swine manure mixtures ratios with the loading quantities of 0.01 ml / g VS and 0.03ml / g VS. The highest biogas yield of 1148 mL / g VS for the co-digesting ratio 40:60 at 0.01ml / g VS was obtained.…”

“…The CH 4 heat content is approximately 26.882 MJ/m 3 or 37.50 MJ/kg and has a density of 0.717 kg/m 3 . Islam et al (2012) and Dzene et al (2016) found that when 0.028 m 3 of biogas was burned, it yields about 2.52 kcal of heat energy per % CH 4 composition. If biogas is composed of 60% CH 4 , it will yield 5,400 kcal/ m 3 .…”

PurposeThe purpose of the study is to analyse municipal solid waste (MSW) disposed of in Jimeta-Yola metropolis for landfill gas (LFG), methane and project viability potential.Design/methodology/approachThe data was collected daily from landfills for four weeks. About 7,329.55 Mg/year of waste was analysed. These waste were separated into bio-degradable components i.e. paper and textile (263.66 Mg), non-food organic (681.45 Mg), wood and straw (189.50 Mg) and food and kitchen waste (1797.20 Mg). Non-degradable components include plastics, polythene bags, metals, sand, stones, cans etc. (4397.73 Mg). The component's characteristics such as a number of samples, weight, volume, landfill age etc. were measured. The waste, methane (CH4) and energy potential were also analysed using LFG energy cost model.FindingsThe landfills received 15 Gg/year of MSW and emit 0.31 Gg/year of LFG having CH4 content of 82.95 Mg in 2016. These can produce 33.78 GWh of heat energy equivalent to 10.14 GWh of electricity analytically. Therefore, between 2016 and 2022, about 2.24 Gg CH4 and 5201.32 MWh of electricity were wasted. Henceforth, proper management of these waste substances can produce 186.4 Gg CH4 which will generate 432.52 GWh of electricity. The most economically viable project is an electricity project generating 418 kW/year at a sale price of $1.14/kWh (58.38/kWh) and a payback period of 11 years.Practical implicationsRaw LFG collected can be used in heating brick kilns, boilers, furnaces and greenhouses. When treated, the LFG can produce renewable natural gas (RNG), which is used in energy generation and various domestic, vehicle and industrial applications.Social implicationsThe analytical energy generation can provide gross revenue of ₦19.46bn at an average of ₦192.71million/year. Using Landfill Gas Emissions Model (LandGEM) model, the gross and net revenue will be $0.42m and $0.28m yearly, respectively. The project can provide jobs and economic boost to the immediate community through associated ripple effect.Originality/valueThe research is a pre-feasibility study for LFG to gas or electricity projects in Jimeta-Yola. The study contributed to the body of knowledge as a source of literature for further studies locally and globally.
