The waste is used to fertilise fields. Their pre-treatment can impact on human health and the environment. A study was carried in Bobo-Dioulasso, precisely in Kuinima and Dogona, with the main objective of assessing the impact of waste treatment methods on the environment and health. The data was obtained from individual interviews with farm managers.
The results show that 56.67% of the producers practise sorting followed by incineration and 20% practised sorting only, 23.33% of the producers did not perform any treatment. Sorting caused injuries to 33.33% of the producers, 10% were harassed by insects. As for the impact of the treatment methods on the environment, 83.33% of the producers who sorted their waste had their fields invaded by new weed species, compared to 76.47% of those who sorted and incinerated. For 88.23% and 66.67% of the producers who were sorting followed by incineration and sorting only respectively, the crop yield was good. From these results, we can conclude that the waste treatment methods used by producers have negative effects on the environment and human health.
