Valorisation of the “organic component of urban solid waste
Valorisation of the “organic component of urban solid waste” through the processes of composting and anaerobic digestion, the case of Ambanja, Madagascar
Authors: Alberto Panissidi, Diego Quarta
Part of a project called “Progetto Madagascar-Ambanja” by Ingegneria Senza Frontiere of Naples answering the requests of an agricultural cooperative in Ambanja (north-western Madagascar) to ameliorate their hygienic conditions in sanitation.
The research focused on the disposal of urban solid waste and in particular on the organic component as this represents 80% of the total.
Today there is no plan for waste treatment, and this is simply stored in unauthorized dumps and burned periodically.

dumps where waste is burned periodically
cement refuse container created within a French project, day 0
same container day 9
wooden box for composting, 75x75x100
biomethanation of the solid organic waste
The research thus develops a system to treat the solid organic waste with processes of aerobic and anaerobic digestion that provide biogas and compost, two important sources of energy.
