Our present study was conducted precisely to determine the effects of long-term incineration on banana and plantain cultivation under the conditions of Masako in particular and the Kisangani region in general whose cultivars Litete, Libanga, Gros Michel and Yangambi Km5 were used as propagating material. Observation included the inventory in the system, average plant height, average diameter, number of functional leaves, number of rejets, rate of infection of cercosporiasis and fusarium wilt, and infestation rate of infection of cercosporiasis and fusarium wilt, and infestation rate of weevils and nematodes. The results of these various parameters showed in particular that the inincinerated block gave a superior result compared to the incinerated block.
It is important to remember that comparing the averages of plants in the same block shows significant differences at the 5 % threshold between cultivars.
Given the state of insalubrity faced by the inhabitants of cities, communities and villages in so-called developing countries, particularly in the Democratic Republic of Congo (DR Congo), a study on the production of waste and its composition with a view to its probable reprocessing would be significant.
In the city of Likasi, DR Congo, this study looked at the case of existing management. Although this management leaves something to be desired, it does allow the bulk of the waste produced to be removed. In practice, the aim was to see what is being done to remove or eliminate the waste produced by the population of Likasi through its various activities. Afterwards, a sample of the waste had to be taken in order to study its composition with the means available.
The results obtained show great potential in the waste, with significant contents of recyclable materials such as paper, plastic and some metals such as aluminium and copper. When reprocessed, this waste turns out to be an invaluable source of wealth.
