The ever-increasing amount of waste as the population grows prompted the primary concern of identifying various methods for reducing the growing amount of waste, in this case, biowaste. Anaerobic digestion methods, when applied to biomass waste, are a cost-effective approach to generating energy while also addressing environmental concerns. The few biodigesters that have been used on the African continent do not live up to their expected life-span. And this is because of lack of a control mechanism to monitor the degradation process in the biodigester. Biodigester monitoring systems that have been used mainly in the developed countries target large bio-energy generating plants. However, these monitoring solutions cannot be used with small house-hold scale biodigesters because of their complexity and high cost. In this project, a low-cost monitoring system of a household-scale biodigester is implemented to help improve the functionality of the biodigesters and in turn increase their life-span.
