The problem of waste management in some
poor countries is usually linked to their non-preliminary
quantification. This study aims at quantifying the flow of
paper and cardboard waste in Maroua town and to
evaluate its recycling capacity for combustible briquettes
production. Paper and cardboard wastes produced by
households, public sector, private organizations and
shopping centers were collected and quantify. The
production of combustible briquettes with this type of
material was evaluated. Some physicochemical
parameters as moisture content, volatile matter content,
fixed carbon content and ash content of the briquettes
were evaluated. The environmental impacts of the use of
the briquettes were determined. Globally, annual flow of
total rejected papers waste was found to be around
81,713.00 kg in Maroua town. Moisture content of
combustible briquettes produced and dried at room
temperature during 7 days is 4.02±0.47%. Higher fixed
carbon content has been observed with combustibles
briquettes made with waste pretreated with alkali
solution (39.99±9.0 %). With total amount of 81.7 tons of
paper waste rejected each year by targeted sectors of this
study, it is estimated the production of 102.141 tons of
combustible briquettes. This was found to be equal to
about 153.2 tons of firewood use as combustible. It
appears that the recycling for the cooking energy
production of paper and cardboard wastes could
significantly reduce the firewood consumption and thus
deforestation.
