Valorisation of the “organic component of urban solid waste

Submitted by admin on March 15, 2009 – 7:44 pmNo Comment

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.

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.
