According to REMA, the disposal of the following wastes with
the rest of the municipal solid waste is prohibited:
? Hazardous Wastes other than those specifically authorized in
the Hazardous Waste
Regulation;

Despite the separation of some kinds of municipal solid waste
as requirement of REMA, Rusizi District Leaders have set up an open dumping
site where all solid wastes are disposed. The following pictures show gaps in
waste management of different municipal solid wastes that are disposed in an
open waste dumping located in Ruganda Cell, Kamembe Sector, Rusizi District.

According to MINIFRA, Rusizi town is facing different solid waste
management challenges
that include:
> There is no centralized garbage collection system;
> Lack of safe disposal methods;
> The municipal council collects garbage from the market and
some of the major
restaurants and institutions, and charges a nominal monthly
fee;
> Lack of designated dumping site / land fill where 50% of the
population relies on
compost pits while 40% of ordinary households on the farms;
> There is no designed garbage dumping site and most of the
garbage is deposited along
road reserves in the outskirts of the town and
> A majority dispose of garbage by burning or dumping by the
road sides.
4.3. Site selection for landfill in Rusizi Town 4.3.1.
Criteria for site selection
