Construction and demolition waste in Tungurahua: A case study from Ecuador

Abstract

This research will make an analysis of the material stock in Tungurahua-Ecuador from 2013 to 2019 using the general purpose of six “s” of Brand (1994) for site, structure, skin and space plan layers, data was taken from the Instituto Nacional de Estadisticas y Censos (INEC), from 2013 to 2019; and for the stuff layer the research applied online forms, the results show that reinforced concrete is the predominantly material used in foundation, structure and skin layers, then bricks and blocks are most common used in space plan layer and timber elements are the most used in the stuff layer, finally the paper proposes some ways to deal with this type of materials and future information to be addressed in new research.
