Aspects of Materials Decay Under Chemical Attack from the Leachate Treatment Plant of the Tirighina Waste Landfill

Résumé

Human society faces a number of major problems among which the increasingly negative consequences of environmental pollution. The high uses rate of the natural resources and the large amount of waste generated tend to transform the natural environment, its feed back reactions becoming dangerous to both life and the constructive environment created. Waste is one of the best indicators that measure economic vitality and the society way of life. The economic growth and development most times generate a quantitative increase and diversification of the nature of waste produced in the processes of making community utilities. Currently, waste management and treatment have become crucial and complex issues to ensure sustainable development. Because most municipal landfills do not have a perfect waterproof foundation, leachate infiltration into the soil, subsoil and underground water may occur causing the pollution of these environmental factors. To this end the paper is focused on the collection and treatment of leachate from the municipal waste landfill by presenting modern technologies for the collection and treatment of leachate from uncontrolled municipal waste deposits.
