Abstract—The influence of waste age on the characteristic of leachate from a landfill site where young and mature waste cells were investigated over a period of six years to evaluate the impact of waste age on quality of leachate generated. Results of the study revealed that the leachate quality is affected by waste age due to its impacts to bacterial growth and chemical reaction in the waste mass of landfill.

Index Terms—leachate, sanitary landfill, bacterial growth, chemical reaction landfill, waste age.
