Abstract
One of the factors influencing the achievement of sustainable sanitation is the
proper disposal of human excrement. The problem is most prevalent in informal
settlements, where sewerage systems are rare. One of the approaches considered
sustainable is the conversion of human excrement into renewable energy via
biogas technology. The purpose of the study, which was guided by Roger's theory
of innovation diffusion, was to investigate the key factors that influence human
excrement management through biogas technology. Mukuru Kwa Njenga slums
were chosen as a study area. A sample of 100 people was selected using
systematic random sampling. Data were analysed using a social science statistics
package. Multiple linear regression was used to determine demographic factors
that influence technology adoption. The Chi-square test was used to examine the
relationship between various variables. Tables and charts were used to present
the data. The study revealed that gender (p=.001) and education level (p=.000)
significantly influence the use of biogas technology in the management of human
excrement. Technology failure ((χ2= 10.301, p=.036) and lack of technical skills
((χ2= 7.518, p=.128) have no significant effect on the technology adoption rate.
Cultural beliefs (χ2= 23.665, P=.000) have a significant effect on the use of
biogas produced from human excrement. The ability of technology to prevent
overflowing of faecal matter during heavy rainfall (χ2= 23.937, P=.000) and the
prevention of odour from sanitation facilities (χ2=17.983, p= .001) has
encouraged many residents to use the technology. The study concludes that
technical and socio-economic factors, as well as its relative advantage over other
excrement disposal methods, influence its adoption rate.
