Three representative samples of construction and demolition waste recycled as aggregates were taken from two different Brazilian recycling plants. The samples were fractioned by sink-and-float and sieving techniques. The chemical composition, the main mineralogical phases and physical characteristics such as bulk specific gravity of these fractions were determined. The applied …

O objetivo desta comunicação técnica é apresentar as razões e estratégias para o aperfeiçoamento do processo de reciclagem da fração mineral do RCD com o objetivo de produzir agregados reciclados com qualidade controlada para uso em concretos. Estas estratégias serão adotadas em um projeto de pesquisa envolvendo o Centro de …

The Municipal Solid Waste Management (MWSM) system was established a century ago to protect public health. It has been modified during the past 40 years in pursuit of public policy objectives of pollution control, resource conservation and, most recently, sustainable development. This report examines the successes and failures of “integrated …
