“…This result apart from being in line with expectation shows a very strong influence on economic growth in Nigeria. The finding corroborates recent literature of Pao and Li (2014) for MIST economies, Olugasa et al (2014) for a study in Nigeria, Pfeiffer and Mulder (2013) for developing countries and Brown et al (2012) for United State. This further shows that combustible renewables and waste is among clean energy endowment that facilitates economic growth in Nigeria.…”

“…This led to the need to investigate clean energy relationship with economic growth in Nigeria. Recently, Olugasa et al (2014) conducted a conceptual review on clean energy production from biogas for use in Nigeria. Having reviewed the global techniques on how to store and generate clean energy from biogas, point out its potential economic advantages and use in meeting energy demand in Nigeria and other developing countries.…”

a b s t r a c tThis paper examines the impact of clean energy on economic growth in Nigeria. Autoregressive distributed lag (ARDL) approach to cointegration was used to determine the existence of cointegration among the variables. The long run results suggest a significant negative relationship between two indicators of clean energy (alternative and nuclear energy and electric power consumption) and economic growth. The result further reveals a significant positive relationship between combustible renewables and waste and economic growth. Mixture of negative and positive relationships between clean energy indicators and economic growth was obtained in the short, although not significantly different from zero. We concluded that Nigeria has Potentials of clean energy to be reaped in near future.

“…To ensure an adequate biodigestion process, it is important that pig manure be sufficiently homogenized, and HRT should be sufficient to prevent endogenous bacteria from being expelled at a higher rate than that of reproduction (11). In this regard, Massé et al (12) reported significant reductions in the concentration of total and fecal coliforms, Escherichia coli, Salmonella spp., Campylobacter spp.…”

Objective. To evaluate the persistence of virus, bacteria, mold, yeast and parasites in liquid pig manure, processed in biodigesters and manure tanks in the central-western part of Colombia. Materials and methods. A directed observational study analyzed descriptively was carried out in three pig farms located where the manure tanks were assembled and its biodigesters were used. A sampling of liquid pig manure was taken to assess the presence of 26 pathogens at the beginning of the study and another one at the end of the process in manure tanks and biodigesters. For the manure tank, a 250 liters tank was filled with fresh pig manure and was analyzed after three days of storage. The biodigesters were of continuous flow and its effluents were analyzed, according to the specific hydraulic retention times. The diagnostic techniques were those recommended specifically for each microorganism and were carried out in certified labs by the Colombian Animal Health authority. Results. Of the 26 pathogens that were investigated, 15 appeared in the fresh pig manure used in pig manure tanks and 12 in the one used in biodigestors. In manure tanks, Porcine Circovirus type 2 (PCV2), mold, yeast, Salmonella spp., Balantidium coli and Strongylids did not persist. In biodigesters, PCV2, yeast, Strongylids, B. coli and Strongyloides spp., did not persist. Conclusions. In both manure tanks and biodigesters, a variation could be seen in pathogen persistency, indicating that they act as transformation systems of pig manure for the removal of the latter, as long as the storage times are increased if the efficiency wants to be improved.

“…An example of a renewable fuel is biogas which simply means "fuel from biological matter". A more comprehensive definition was given by Olugasa et al [1] and described biogas as a of the mixture of carbon dioxide, CO 2 and inflammable gas Methane, CH 4 which is produced by bacterial conversion of organic matter under anaerobic (oxygen-free) conditions.…”

This paper discusses the results of studies conducted on raw biogas produced from a prototypic biogas production plant located at the Teaching and Research Farm, University of Ibadan, Ibadan. This setup consists of a mixing chamber, a biogas digester and a stabilizing unit, locally designed and fabricated. It further discusses preliminary and detailed design coupled with the construction of an effective and efficient technology used in purifying raw biogas generated from the prototypic biogas production plant; this technology is otherwise known as the Water Scrubbing technology. The Scrubbing system consists of the Water scrubber with iron wool packed bed connected to a 500 litre water tank, and two tyre tubes which were used in storing the pre scrubbed (raw) biogas and the scrubbed (purified) biogas. The water scrubber has an inlet for the entry of the raw biogas and a discharge for the exit of the scrubbed biogas. Raw biogas from the plant was stored in a tyre tube and directly fed into the Water scrubber housing the iron wool packed bed, the purified biogas from the exit was also collected into another tyre tube. The samples of the gas mixture were taken before and after scrubbing and analyzed with Pascal Manometric Glass Tube technique. Results indicated that methane content of the scrubbed/ purified biogas was raised from 58% to 82% due to the reduction of Carbon dioxide and Hydrogen Sulphide. CO 2 was reduced from 31% to 14% while H 2 S was reduced from 1% to 0.4%.The corresponding Energy content of the purified biogas was evaluated to be 41MJ/kg which is higher than that of the raw biogas which was evaluated to be 29MJ/kg. Design and Construction of a Water Scrubber for the Upgrading of BiogasTemilola T Olugasa* and Oluwafemi A Oyesile Department of Mechanical Engineering, University of Ibadan, Ibadan, Nigeria enrichment in rural areas, and characteristic as a universal solvent. In addition to these, the packing material in the scrubbing setup increases the contact time between the biogas and water. This work is therefore aimed at providing an effective and efficient scrubbing technique that would be capable of removing significant amounts of Carbon dioxide and Hydrogen sulphide, resulting to an increase in the energy content of biogas and the recommendation of the commercial use of purified biogas in Nigeria [3][4][5][6][7][8][9][10]. Materials and Methods Assessment and selection of a biogas plantThe biogas plant at the Teaching and Research Farm, University of Ibadan was selected as the case study. This biogas plant has a biodigester of 2 m 3 capacities, a mixing chamber and a stabilizing unit. 8 kg of Cow dung was transported from the dairy farm, University of Ibadan to the location of the biogas plant at the Teaching and Research Farm. The system was charged with cow dung at the ratio of 1:1 (water to cow dung) and left in an open area with ambient daily average temperature of 31.5 o C and monitored for a period of 14 days. After proper mixing in the mixing chamber, the system was left air-ti...
