Management of Construction Waste:
LCA and Complex System Modeling
Anne Ventura and Maxime Trocmé
Abstract Construction and demolition waste (CDW) generation, identified as a
priority stream by the European Commission, accounts for approximately 25 to
30% of all waste generated in the European Union. According to local specificities
(e.g. regulations, waste management organization) best environmental options may
differ for transforming waste into new resources. Five oral presentations were given
in the session which focused on innovative modelling initiatives combining LCA
with complex models in order to improve knowledge for more sustainable urban
construction waste management. During the discussions, all participants agreed that
re-use or recycling mass performance is a weak and unsufficient indicator for
assessing waste management systems. There is an important need for better characterizing stocks and predicting nature and quality of output flows. Geospatialized
data combined with Material Flow Analysis was the methodology identified and
used by the research community.
