Impact assessment of existing Biogas Plants in Rwanda. Case study: Kayonza District

Abstract

There are challenges registered in recent years due to the energy industry growth [1]. The elaboration of several technologies have been improved aiming to address this types of challenges. Among numerous technologies that have been improved, biogas technology shown a high potential to be likely to drive the energy revolution [2]. By the way, energy is crucial in the increase of countries economy and development as reveled in several studies mentioned in the literature. The Biogas figures among relevant options that has been adopted to solve energy availability issues for household in rural area of Rwanda. Nevertheless, from the biogas plants implemented in Rwanda, most of them are not operating. This dissertation addresses the impact assessment of existing biogas plant in Rwanda specifically, in KAYONZA district and the objectives are to assess the economic, social and environment impact of biogas in rural area, to examine the root causes of biogas failure in rural area, to establish the role of community in using the Biogas in their household and to review biogas sustainability and environmental protection. The study was conducted on 134 respondents calculated. In the reference [3] a representative sample of at least 10% or 20% of the inhabitant can be applied. For that reason, 20% of the population was considered. The analysis shows that biogas is more important in country development especially in rural area but the issue is that existing biogas are not followed up as required which make more household to abandon it.
