Food waste produced lactic acid for pathogen inactivation, urea stabilization and odor control in feces

Source separated human feces can be used as a valuable source of nutrients if it is properly sanitized and its nutrient is conserved. In this study, the efficiency of fresh cabbage waste produced lactic acid treatment of human feces as a pretreatment to evaluate the sanitizing effect, urea stabilizing, and odor removal was investigated for 33 days. Four reactors were used for the treatment process containing different...

Spatio-temporal distribution of Naididae tubificids species and bio-evaluation of the quality of some surface water bodies of Yaoundé, Cameroon

Despite their great interest for the integrated management of water resources, information on the ecology of aquatic oligochaetes is still sketchy in Cameroon. The present study aims at contributing to the knowledge on the distribution, microhabitat and life history of Naididae tubificids taxa in some eight water bodies of the city of Yaoundé. A total of 132 samples were analysed and the morphospecies Branchiura...

Application of renewable technology for mitigating environmental hazards of palm oil industry: Strategy for climate change and adaptation

Improper disposal and burning of agricultural residues are commonly practiced in some developing countries in which harmful gaseous products released into the atmosphere and some are depleted and reacted with the soil causing environmental pollution. Renewable technology can therefore be introduced for the utilization of the residues and ensure proper storage medium of the residues. An investigation was carried out on...

Analysis of the influence of precipitation patterns on wetland sizes in South-Eastern Zimbabwe

In this paper, the hypothesis that rainfall variability has an impact on wetland loss is tested. There is limited research in Zimbabwe that recognises the influence of rainfall variability on wetland loss. The purpose of this research is to determine the influence of rainfall variability on wetland size over time. Topographical maps, for the period 1972 to 2008, provided data on wetland locations and their changes in...

Assessment of heavy metal concentrations in Mango fruits grown in Kasese district, Uganda

Fruits are a good source of carbohydrates, sugars, dietary fiber, fat, proteins, vitamins and minerals. In this study, mango fruits grown in Kasese as well as the soil and irrigation water used in fruit growing were analysed for heavy metals cadmium (Cd), chromium (Cr) and lead (Pb). The mango fruits and soil samples were obtained from three sites; Mubuku Irrigation Scheme, Mpondwe-Lhubiriha Town Council (MLTC) and...
