A possibility of landfill mining in Portugal: waste characterization

Research output: Chapter in Book/Report/Conference proceedingConference contributionpeer-review


Mining dumps and landfills involves the excavation, separation and treatment of various components of the waste that was deposited in old dumps and landfills, with advantages for the management of natural resources and environmental conservation. The analysis of a possible landfill mining in Portugal concerning forecasting evaluation of materials existing in the dumpsite is the aim of the study. The results show that the degradation of biodegradable waste is not as fast as expected, where some waste still remaining in a relative considerable conservation. For the composition of the waste, the fine fraction is the predominant component (55%), followed by the combustible material (23%). The amount of waste deposited over the 16 years of operation (from 1980 to 1996) is estimated to be of the order of 670,000 tons, occupying a volume of approximately 900.000 m3 .
