In the commune of Masina, as elsewhere in the democratic republic of Congo, the sector of rudology or the systematic study of waste has so far been little or badly known. Thus, technical studies and scientific research must be carried out to better understand this sector and spare the populations from various consequences linked to poor waste management. It is in this logic that is located this study which consists in making an inventory of fixtures on the management of the municipal waste with a view to possible improvement. At the end of the investigations, it appears overall that the solid household waste management system set up in the municipality of Masina is anti-ecological. This is explained by the combination of several variables, in particular: - the absence of a real policy of ecological development of the territory, of good governance and of environmental education/responsibilization of the population; - the ignorance and ecological incompetence of the municipal authorities (77%), the team in charge of waste collection (100%) and the inhabitants of the municipality of Masina (71,4%); - a multifaceted poverty (moral and materiel) and a negligence of the residents which lead them to live in insalubrity; - the use of unsuitable and non-ecological solid waste management methods and techniques (39%). Therefore, it seems urgent that producers of waste and decision-makers question themselves and make amends in order to assume themselves differently as consumer-pays and polluter-pays.
