Harvest Map – alternative sources of building materials

In this paper, after the brief description of main constraints and determinants of sustainable circulation of construction waste in urban areas, the Harvest Map tool is presented. The general information is followed by the analysis of individual maps for different cities and related projects as well as of online databases. Moreover, the local research developed for the municipality of Konstancin-Jeziorna is examined and general guidelines for sourcing construction waste in Polish cities are established. This detailed presentation of the Harvest Map tool demonstrates how building materials can be sourced, processed and managed in urban areas as well as how policymakers, urban planners, designers, contractors and other interested stakeholders can participate in the reuse of construction waste. It shows how an open-access, free, participatory and innovative tool can create and boost sustainable circulation of building materials and enable more frequent implementation of reused materials in architectural projects.
