Circular Economy: multicase study about recycling plants in waste management of civil construction solid wastes

Abstract

With the purpose of recycling construction and demolition wastes (CDW), CDW Recycling Plants (CDWRP) reduce the impact of the sector on the environment. This paper presents a discussion about the role of CDWRP in the promotion of the Circular Economy in the management of construction waste. A multicase study  was used in seven CDWRPs located in the region of São Paulo, as well as interviews with CDWRPs managers, the President of the Brazilian Association for the Recycling of Civil Construction and Demolition Waste, as well as engineers with experience in civil works It is concluded that CDWRPs have potential in the promotion of the Circular Economy, however, they present limitations; the lack of quality programs for recycled aggregates, the use of inefficient screening methods, low labor qualification, lack of clarification to the market, and lack of laws that encourage the use of waste in construction.
