In developing
countries, sorting-composting of the urban solid residues (USR) requires the
use of tools adaptable to the local conditions.
To determine
these optimal conditions of the process of
sorting-composting of the biodegradable materials, an experiment
was thrown at the level of the municipality of Chlef in Algeria. The parameters
of follow-ups of the process of the fermentation were studied.
The produced
compost contain of the rates in N, P, K, % in Carbon (%C), % in Organic matter
(%OM) and reports in C/N acceptable by the standard NFU 44 051 (the french
standard of the organic amendments).
