Abstract :
- The sorting of municipal solid waste (MSW)
by residents is a recommended and inexpensive practice
that allows sustainable waste management with the
recovery of homogeneous fractions for further
valorisation. However, MSW continues to be collected
unsorted and is sent to new uncontrolled open-air
landfills, despite the recommendations. The purpose of
this study is to analyse the MSW management in
Bujumbura city and to identify the main problems that
hinder the sorting of waste by the inhabitants.
Methodologically, on site visit was carried out to
establish an inventory of the dispersion of MSW in the
city. To assess the profile of their impact, leachate was
sampled and characterized (pH, electrical conductivity
and heavy metal content by ICP-MS). In addition, to
understand better the MSW management in
Bujumbura, a survey questionnaire was used on a
random sample of 80 citizens of Bujumbura aged 10
years and over. The results showed that MSW was
found in an unsorted and uncontrolled open-air landfill.
The heavy metals content of the leachates sampled
exceeded the limit value for Cu, Cr, Fe and Mn.
Moreover, the survey realized in this study shows that
the majority of Bujumbura's citizens (76.3%) do not
sort MSW. They face various challenges such as the
lack of adequate information on MSW management, the
lack of separate containers, the collection of waste by
categories and the lack of collection services. The chisquare test showed a significant dependence between
the involvement of the local administration in raising
awareness of sustainable management and the way in
which municipal solid waste are managed (p <0.05).
However, referring to coefficient of contingency (0.390),
this relation is weak and additional factors would be
useful to justify the actual management of MSW in
Bujumbura. To ensure MSW sorting and sustainable
management in Bujumbura, the specific intervention
points are highlighted and concern: the wide
dissemination of information through the media, local
administration, the development of waste collection and
recycling services, environmental education through the
Burundian education system. Government and other
stakeholders should invest in order to provide all the
information necessary to promote the successful
establishment of the city of Bujumbura.
