Pit latrine faecal sludge solid waste quantification and characterization to inform the design of treatment facilities in peri-urban areas: A case study of Kanyama

The purpose of the study was to quantify waste content in faecal sludge using an appropriate method and characterise the solid wastes inherent with the faecal sludge into categories. A total of eight (8) domestic pit-latrines were analysed in the peri-urban area of Kanyama settlement in Lusaka from July to October, 2018. From each latrine, three (3) samples were obtained for analysis of solid waste and sand/grit...

Residues of the transformation of halieutics products: An alternative substrate for energy valorization of wastes by methanisation for a local sustainable development (preliminary results)

The purpose of this study is to evaluate the biogas productivity potential of residues of the transformation of halieutics products. Experiments were conducted in two digesters of PUXIN model of 20 m3, where the temperature is 35°C. Multirae analyser was used to know the composition of biogas produced. A gas counter was also used for counting the amount of biogas produced during the experiment. There was also a...
