EVIAVE, a new methodology for landfill management
Scientists of the University of Granada, UGR (Spain) have designed a novel and versatile environmental diagnostic method of landfills which is able to adapt to different places of the world and contributes to quantify the environmental impact. The study produced a method helped by a software tool that analyzes the relation between landfill dynamics and their influence on different elements in the environment. It also permits to control harmful impacts such as bad smell and superficial and subterranean water pollution.
For this purpose, a set of environmental indexes are specified, which quantify the environmental impact of landfills (Environment-Landfill Interaction Index, Environmental Risk Index, Environmental Value Index, and Probability of Contamination Index).
The work defines the pollution probability of the landfill according to the exploitation level, as well as to its location. This method tracks all the phases of the life of the landfill, advising on different measures to be taken according to the pollution levels, such as plans for upgrading the installations or eventually closing them.
The method (EVIAVE by its initials in Spanish – Intelligent Valuation of the Environmental Impact of Landfills) follows the EU legal requirements for non-hazardous waste landfills, but it may be easily adapted to other countries with different legal frameworks and socioeconomic characteristics. In fact, the new EVIAVE method has already been tested in landfills from Chile, Colombia, Spain and Venezuela.
