Physics

The present study, which was carried out during the period from February to April 2022 in the city of Kindia, had as its general objective the study of the management of solid household waste in the urban municipality of Kindia. The specific objectives relate to determining: average daily production of waste per household, per inhabitant and per district; average daily production of types of waste per household; the average ratios by type of waste and the annual production of household waste in Kindia. The survey covered ten (10) households in eighteen (18) neighborhoods out of the thirty-three (33) in the town of Kindia. The main results obtained are: the average daily production of DMS per household for three months, February (41.87 kg); March (53.62 kg) and April (56.66 kg); the average daily production per inhabitant (0.62 kg/capita/d); the average annual waste production of the 18 neighborhoods (1157.07 tonnes per year) for a population of 92,413 inhabitants; that of any city of Kindia (37883.479 tons per year) with a population of 170437 inhabitants and the average ratios by type of waste, fermentable (60.01%); cardboard/paper (2.50%); textiles (5.51%); plastics (6.24%); glasses (0.16%); metals (0.09%); sands (9.99%) and others (15.50%). These results show that the production of waste per household is a function of the standard of living of the populations of the different neighborhoods (low standing, medium standing and high standing) and the different activities carried out by these populations.
