- Description: Abstract: There are presently 600 million of people in Africa without access to electricity. To resolve this issue, 100 million of new connexions are needed. These new connexions require more investments in propice environments. However, most investors have reduced their risk appetite for Africa due to the absence of adequate regulatory and policy framework in the energy sector. Many utilities are no longer bankable and trustworthy like before. Stakeholders do not have sufficient financial resources to build or rehabilitate energy infrastructures. Statistics reveal that public institutions will need the support of the private sector in order to emerge. As such, Public and Private Partnerships (PPPs) leading to strategic investments seem essential for the deployment of the African energy sphere. Mini-grid systems are recommended as potential tools for local electrification that will lead to the economic boom of Sub-Saharan African (SSA) developing countries. The challenge is that a suitable business model for mini-grid is not yet identified and continue to be developed. For this reason, this paper aims at encouraging the development of a regulatory framework and replicable business model that will be used by other mini-grid developers to attract strategic investments to implement projects starting at the village level.

- Description: Abstract: In this investigation, the anaerobic digestion (AD) results from different substrates were evaluated. By means of two co-digestion processes with cow dung, it was observed a good performance in the first process and a poor production trend in the second one. NaOH was used as chemical absorbent in two different bottles in the CO2 fixing unit to compare the volume of biomethane produced. A batch anaerobic codigestion was carried out in 500 mL digesters which were placed into a water bath at 45°C and maintained at the initial pH of 7. Important AD factors such as pH, Carbon and Nitrogen ratio (C/N), concentration, substrate composition were observed. Through an ultimate analysis, amount of Carbon (C), Hydrogen (H), Nitrogen (N), and Sulphur (S) were also discussed. The toxicity of other elements found in substrates appeared higher in the second process than in the first. It was concluded that inhibitory elements identification and control before furthering any biogas production process were primordial.

- Description: Abstract: Soil analysis was carried out on samples collected from a farm located on the out scares of Thokoza Township in Johannesburg, South Africa. The Farm operational site currently used for farming was once a waste dumping site. The moisture content of different samples was determined with an initial weight of 100g; each sample was placed in an oven and heated at 107 °C for 2 hours. The X-Ray fluorescence (XRF) analysis was used in the determination of samples composition. Magnesium (Mg), Calcium (Ca), Potassium (K) and Phosphorus (P) were mainly discussed in this study. Horse dung and crushed bones were reported more suitable as fertilizers due to large amount of K and P considered as potential plant growth catalysts. Wood saw dust revealed particularities in its effect on sand especially in agriculture. The purpose of this study was to analyse, compare and predict the impact of horse dung, crushed bones, and wood sawdust in the land remediation and fertility improvement.
