Municipal solid waste landfill is a potential source of contamination due to the harmful elements of the leachate, such as trace elements. In the Belo Horizonte landfill, the waste is partially disposed of directly on gneiss saprolites, with lower capacity to mitigate contaminants than upper soil horizons. Column tests were made to analyse the attenuati...
View ArticleThis paper describes a mechanical device to compare the energy transference from the blow of a hammer to the stem referring to standardized and non-standardized equipment in Brazil. The device allows to measure the vertical displacement of a sleeve due to one or more blows of a hammer falling freely. Tests were carried out using three pieces of equipmen...
View ArticleThis paper presents a study on the compressibility of municipal solid waste (MSW) by means of a field survey in Valdemingomez Landfill in Madrid, Spain. Organic matter content was 59%, there was no waste segregation and field compaction, nor internal drainage systems for gas and leachate. Solid waste management changed significantly since then in Madrid...
View ArticleThick wall (6.6 mm wall thickness) plastic samplers, 97.2 mm in internal diameter (area ratio of 29%), 700 mm in length (length of soil sample 640 mm), with a cutting edge angle of 23°, without clearance and with a sampler head have been used to collect very soft clay samples at Sarapuí II test site. Very good to excellent an...
