%X High population spikes have been projected for developing countries in the nearest future. This
development is a source of concern as there are no visible futuristic economic agenda to douse
the menace of population growth in a dying economy. This paper is a blueprint for standalone
energy users and the built industry to improve energy generation using sustainable materials, i.e.,
human and agro waste. This research examines two popular agro waste i.e., plantain peel and
Siam leave. The concept of bio-digester septic tank design (BDSTD) was also discussed. Biogas
from plantain-faecal (PF) had a higher cumulative production than biogas from Siam-faecal (SF)
because plantain biomass aids initial bio-digestion of the faecal samples due to its inherent
chemical components which are important to breaking undigested food component in the faecal
mass. In this wise, the chemical component in Siam biomass cannot easily break undigested food
components in the faecal mass. However, SF creates a better enabling environment for microbial
growth that could lead to about 400% biogas generation over PF and 160% biogas generation
over pure faecal (TF). Despite this feat, the caveat for improved daily gas production rate in SF
is hinged on pre-processing of the faecal mass. With the aid of machine learning, it was revealed
that higher retention time could be a natural way of pre-processing needed by the Siam biomass.
This concept led to the design of the BDSTD which was technically hinged on cross-sectional
partitions. Plantain biomass is recommended for four partitions BDSTD design as there would be
shorter retention time in the overflow chamber while the Siam biomass is recommended for > 4
partitions BDSTD designs.
