Depuis le tout début, l'homme est un élément dynamique de l'environnement. L'augmentation de la population et l'industrialisation ont conjointement affecté l'environnement à des niveaux inattendus. La gravité du problème a attiré l'attention du monde entier sur la tendance écrasante de cette calamité. Il est tout à fait vrai qu'aujourd'hui, la gestion des déchets solides est un défi majeur dans les zones urbaines du monde entier. Le problème de l'élimination de quantités toujours croissantes de substances solides est devenu un casse-tête non seulement pour les pays industrialisés et développés, mais aussi pour la plupart des pays en développement. Environ 1 % du PNB et 20 à 40 % des recettes municipales des pays en développement sont consacrés à la gestion des déchets solides. Ce secteur emploie jusqu'à 6 travailleurs pour 1 000 habitants, ce qui représente jusqu'à 2 % de la main-d'oeuvre nationale. La mauvaise qualité des services fournis dans la plupart des zones urbaines, en termes de quantité de déchets solides collectés et de protection de l'environnement. En Asie, la production de déchets solides a atteint 1 million de tonnes par jour. Selon la Banque mondiale, les zones urbaines d'Asie dépensent 25 millions de dollars US par an pour la gestion des déchets solides, et ce chiffre passera à 47 millions de dollars US.
