Résumé

Pre-treatment of paper waste cartons for making briquettes fuels that can be used in substitution of safe firewood for the environment is one of the means of management efficient waste. The objective of this work is the pre-treatment of paper and cardboard waste with locally available products. The stadium preliminary waste pretreatment paper-cardboard consisted for a time of average maceration of 84.21 hours in NaCl (0.1mol, pH 5) to separate the particles coarse paper fiber. De-inking with weak acid solutions (CH3COOH, 0.1 mole/liter, Ph 3), strong acid (H2SO4, 0.1 mole/liter, Ph 4) and weak alkali solutions (NaOH, 0.1 mole/liter, Ph 8) have made it possible to obtain the same level of average deinking which is 45, while in a strong alkali solution (NaClO, 0.1 mole/liter, Ph 9), the deinking proved to be a little more important of the average order of 57. The ratio COD/BOD5 between 3.39 and 14.96 allowed to consider a physicochemical pretreatment. The leachate resulting from de-inking has been decontaminated using the filters and have been reused or discarded without major danger to the environment while the polluting residues were buried in the unload. Fuel briquettes made from untreated paper-cardboard have a power calorific value is 12.53 MJ / Kg, very close to those completely deinked which is 12.65 MJ/Kg.
