STATE OF THE ART OF PRACTICAL APLICATIONS FOR THE USE OF THE RECYCLED MATERIALS THROUGH REAL CASES IN PROJECTS IN CATALONIA

摘要

The use of recycled materials in projects has been flowering in Catalonia in two principal ways. At first in site approaches have been developed in several infrastructures projects, due not only to the increased environmental trend but also to the large amount of non-profitable materials. In the other hand it has been possible to promote the use of certain recycled products obtained in specific external facilities through modifications of the ongoing project, resulting in a significant environmental added value. Both cases are analysed accordingly with several real practical applications that have been or are taking place in projects in this country: recycling of former road pavements sections into aggregates through demolition procedures, use of artificial aggregates in street pavements, valorisation of vegetal waste in gardening projects, recycling techniques in contaminated areas, and another examples. Serious research work, high degree of cooperation between public administration, engineering companies and contractor, and strong environmental commitment were needed in order to achieve a highly satisfactory result.
