Constantine, with a population of 480,000 and containing 90,000 households, generated 164,250 tons of solid waste in 2015 in which domestic waste is the primary source. The aim of this study was to assess the situation of municipal solid-waste (MSW) management in Constantine. Actually, the collection and transportation of solid waste is managed by the municipality, with a small participation of the private sector. More than 90% of the municipality solid waste is disposed and treated in an environmentally sound manner (landfill). Unfortunately, there is a poor culture with respect to the 3R principles (reduce, reuse, recycle) in Constantine leading to a rapid growth of waste generation which has overwhelmed the capacity of the already saturated available landfill. There remain important challenges in solid waste management for the municipal authorities in Constantine which include: the proper management of the financial resources, public education aimed at reduction and separating household waste and optimizing the existing collection system.
