Leachate landfill simply refers to landfills specifically designed to capture leachate. It is important to note that leachate acquired or derived from a landfill/s varies according to two main factors in regards to composition. These factors include; landfill age and the type of waste a landfill contains.
There are two main types of waste namely dissolved and suspended waste material. Leachate landfill generation is as a result of precipitation percolating through the waste deposited on landfills. The contact between water and solid waste causes decomposition. Percolating water in turn becomes contaminated flowing out of the waste as leachate.
Additional leachate is produced through processes such as carbonaceous material decomposition which produces a very wide variety of harmful materials i.e. methane, organic acids, carbon dioxide, simple sugars, alcohol and aldehyde’s.
