“…The BOD and COD obtained is similar compared to the report of Hammad et al [18] and Abdulkarim et al [19]. Although the COD obtained were higher than those obtained in Hammad et al [18] and lower than those obtained in Abdulkarim et al [19] while the BOD obtained were the same with the report of Hammad et al [18] and higher than those obtained in the report of Abdulkarim et al [19]. Electrical conductivity determines the capability of cow dung to allow electrical current to pass through it.…”

Production potential of cow dung for the generation of electricity was investigated using microbial fuel cell (MFC). Cow dung was collected from FUTA farm and Ilesha Garage farm in Akure. Voltage and current was measured per day for 21 days and the electrode used for the set up are carbon-carbon and carbon-aluminium electrode. Proximate, physico-chemical and mineral composition were determined using standard methods. Isolation and identification of microorganisms present in the cow dung were determined before and after generation of voltage and current using microbiological techniques. The microorganisms isolated were Providencia alcalifaciens, P. rettgeri, P. stuartti, Escherichia coli, E. fergusonii, Morganella morganii, Staphylococcus haemolyticus, S. aureus, Micrococcus luteus, Fusarium solani, Saccharomyces cerevisiae and Mucor mucedo. The highest voltage 0.737±0 mV and electric current 1.265±0 mA were generated from FUTA cow dung. The pH ranged between 7.3 to 9.9 and the temperature ranged between 25 ˚C to 33 ˚C during generation of voltage and current. This study has shown that cow dung is a potential substrate for generation of electric current using fabricated double chamber MFC.

“…Since the anaerobic digestion processes are strongly influenced by pH, they can however take place optimally in the vicinity of neutral pH = 7 and between 6.5 and 7.5 giving a good yield for certain types of substrate and in better conditions. In our work, the results of the pH measured on the experiment in Chad are similar to the work of [40] and for the experiment carried out in Senegal the result is close to that of [41].…”

In this work, we have produced biogas by co-digestion of cow dung and slaughterhouse wastewater under different climate temperatures in two countries: N'Djamena in Chad, a country of Central Africa and Dakar in Senegal, a country of West Africa. In a first approach, we put the cow dung in cans of 1.5 L, hermetically closed. The goal was to know how long you could produce biogas. Then we built a bio-digester to produce biogas for cooking. Each bio-digester was exposed to receive solar heat that varied between 27˚C to 41˚C in Chad and between 24˚C to 30˚C in Senegal. Influenced by the high temperature and a minimum residence time, the experiments showed that the N'Djamena test produced biogas more quickly than the Dakar test which, on the contrary, had a low temperature and a long residence time. The production of biogas began at the end of seven days with flammability on the twenty-first day for the bio-digester in Chad and after twenty-seven days with a flammability on the thirty-sixth day for the bio-digester of Senegal. The different digestates were valorised in fertilizers, bricks and green coal. Our research aims to meet the living conditions of the rural world specifically for women by reducing their work and thus allowing them to have more time to self-educate and educate their children.

“…Literature on biogas production from both photosynthetic marine macro-(e.g., Gregeby & Welander, 2012;Risén et al, 2013) and micro-(e.g., Rui et al, 2008) biomass harvested from the wild have shown good biogas yield when used as co-substrate to other input waste streams, for example, manure. Previous studies on the efficacy of digestate as biofertilizer from anaerobic digestion of manure have shown improved qualities for soil (e.g., Hammad et al, 2019) and the resulted crops (e.g., Hammad et al, 2018). Ongoing studies exist where wild cyanobacteria and macroalgae are incorporated but are not yet finalized or disclosed.…”

Recurring summer cyanobacteria blooms in the Baltic Sea has gained academic interests for decades. The harvest of wild cyanobacteria, for example, Nodularia spumigena, during summer blooms in the Baltic Sea has been studied in the past but lacked evaluation for environmental and economic performances. This study provides a first-hand assessment of environmental and economic performance from an energy perspective, using energy return on investment (EROI) as evaluation method where harvest of biomass and the downstream conversion of biomass to biogas and biofertilizer are considered for Gotland, Sweden. Energy analysis results indicate fuel consumption during harvest and transport operations to be the major energy consumer. Traditional sailing boats have been suggested as an alternative. Overall, when considering only biogas yield and usage of sailing boats, a break-even EROI of 1 is achieved. When including biofertilizer as product, a breakeven EROI of 1 is also achieved. Depending upon the biomass concentration in the Baltic Sea at the time of harvest, an EROI > 6 is possible, surpassing the economic viability EROI benchmark of 3, indicating the importance of nutrient recovery as the driver for harvest of wild cyanobacteria biomass during blooms in the Baltic Sea. This article met the requirements for a gold-gold JIE data openness badge described at http://jie.click/badges.
