A Physical Model for the Sustainable Transformation of Human Waste into Biogas in Housing

Abstract

The study presents the conversion of waste to biogas and its implications for housing development by analysing biogas production approaches and utilisation methods. The study looked at the method of biogas production that is appropriate for generating the incessant operation of biogas schemes in housing, as well as the factors for establishing biogas plants in residential buildings. An experimental variant that includes combinations of liquid human and animal waste compost and houseplant extracts was developed and established to create biogas and increase its yield. The gas engine assessments were carried out for energy applications. The eco-energy arrangement was fabricated by considering the precise housing and local situations. The study takes on one household member in a residential area in Ibadan as a case study, and consequently, the amount of liquid humanoid manure generated was 438 m³/year and 2.4 m³ of biogas was generated per day. The findings indicated that human fluid manure should be aided in producing the essential biogas measure and fuel quality and quantity for the household’s energy demand and supply requirements and needs. The study generated a simple biogas application and production method by developing variants and alternatives in which both the waste disposal and the biogas production objectives were accomplished together. The study concluded that for sustainable transformation of human waste into biogas in housing, it is vital to include a biomass plant within the household design scheme, in which biogas plants are in constant operation and biogas is constantly produced for household energy use.
