Construction demolition waste (CDW), a perspective of achievement for the city of Barranquilla since its management model

Abstract

In recent years, there has been a significant increase in construction

projects in the city of Barranquilla, leading to contamination in soils

and water sources due to the inadequate generation and disposal of

Construction and Demolition Waste (CDW). It is clear that this is not a

local problem alone but that it involves trends present at a global level,

which have led several countries to design measures for an adequate

management of waste generated on building sites. Some examples of

this adequate management are: reincorporation of CDW in construction

processes, reuse or use of CDW as raw materials, processing of CDW

to be converted into mineral aggregates for concrete and asphalt and

the use of CDW as mineral fillers. In this work we present results of a

study carried out in 75 construction sites located at different areas of

the city of Barranquilla. We have carried out a detailed survey to assess

the management, treatment and final disposal procedures, thus leading

to a clear identification of relevant issues to deal with in this field, as

well as improvements in the knowledge in the local legislation for the

management of CDW. Based on the results obtained here, we have identified

that the CDW management practices that the construction guild

is currently carrying out are not adequate to solve these problems and

that a more practical and long term solution needs to include a proposal

to improve the management model (involving use and transformation)

and its posterior implementation in the city of Barranquilla.
