Publication Effect of Process Techniques on Three Feedstocks Mix on Briquette Performance Properties(Journal of Energy, Environmental & Chemical Engineering, 2022-02-16) Okwara, Wilberforce; Nyaanga, David; Aguko, Kabok; Nyaanga, JaneEnergy availability at domestic level is a challenge across the world and especially in Africa. Firewood is the major source of energy for cooking for households in Kenya and there is need for a friendly sustainable environmental fuel. Carbonized biomass materials (briquettes) are considered a substitute. This study thus evaluated effect of selected briquetting techniques on briquettes’ performance properties. Milled charcoal dusts mixed in a ratio of 1:1:1 (Rice husk, maize cob, and sugarcane bagasse) with molasses binder in the ratio of 6:1 was hence ready for densification and agglomeration. The Water Boiling Test was used in determination of the briquette’s performance characteristics for various parameters. High (screw press); and low (drum agglomerator and hand making) pressure briquetting techniques were distinctly different in ignition time (minutes), time to boil (minutes) burning rate (g/min), specific fuel consumption (g/ml) and power output (kW) values as (4, 3, 3; 14, 12, 11: 0.8, 1.1, 1.3; 0.11, 0.13, 0.15; and 1.8, 1.4, 0.75). Diversified briquetting techniques, number and type of feedstocks are thus factors that influence performance characteristics of briquettes in converting the agricultural and or other wastes for useful energy application. This knowledge should enable users to make choices on techniques for optimum efficiency towards realization of Sustainable Development Goal Number #7 on affordable and clean energy.Publication Knowledge and Awareness Determinants of Renewable Energy Technologies: A Cross Sectional Study of Rural Residents from Njoro Constituency, Nakuru County, Kenya(IOSR Journal of Environmental Science Toxicology and Food Technology, 2020-09-03) Kimani, Martin Njoroge; Makindi, Stanley Maingi; Aboud, Abdillahi A.Background:Awareness to renewable energy technologies (RET) can have multiple positive effects as it can be a precursor to greater RET adoption levels as well as promotion of the same. The aim of this study was to assess the level of awareness of rural residents of Njoro constituency to the different renewable energy technologiesas a precursor to their adoption. Materials and Methods: The study was based on primary data collected through personal interviews with household heads in Njoro constituency, Nakuru County, Kenya. Two stage cluster random sampling was used to select the 200 households. The results showed that majority of the respondents exhibited a moderate level of knowledge and awareness to RETs. Results:Results of the study indicated that gender and education level had a significant effect on knowledge and awareness. It was also found that age and social-economic status did not have significant effect on the knowledge and awareness. Conclusion:The overall finding of the study underlined the high importance in strengthening communication to enhance knowledge and awareness of renewable energy technologies. The findings of this study will be significant to planners, policy makers, researchers and individuals to build the case for proactive promotion of RETS.
