Based on the life cycle sustainability values of adaptive reuse, policy strategies
were recommended to promote and incentivize this alternate design approach in
Singapore.
5 Evaluating the Construction and Demolition Waste
Management System Implemented in Lombardy Region
(Italy) Through Life Cycle Assessment
Among Italian regions, Lombardy was the largest producer of CDW in 2014, with a
rough equivalent of 1 ton of CDW per inhabitant during the year 2014. Hence, the
establishment of an effective and sustainable CDW management is essential to
ensure environmental protection and enhance waste valorisation towards a
resource-efficient system. Lucia Rigamonti presented the results of the overall
environmental performances of the CDW management system currently implemented in the region, based on LCA [4]. The quality of secondary products
obtained from CDW and their actual use has been considered. A focus has been
made on the technical characteristics and the actual market of the recycled aggregates, allowing to estimate the type and amount of “avoided natural materials” that
can be replaced by recycled products. The environmental benefits due to the
“avoided impacts” have been calculated. Based on LCA results and a literature
state-of-the-art of treatment technologies, alternative scenarios for CDW management strategies, innovative processes and/or alternative recovery solutions (i.e.
“alternative scenarios”), have been defined. LCA results for the alternative scenarios were compared to the results of the current situation to quantify the benefits
arising from the suggested improving actions. Results have been used to provide
recommendations to the regional authorities to enhance the CDW recycling chain.
6 Alternatives for Materials from an End-of-Life Building,
Evaluated with Life Cycle Costing and Life Cycle
Assessment
Valentina Prado-Lopez presented a study derived from the EU Horizon 2020
HISER research and innovation program [5]. Two scenarios of demolition waste
management were compared, a ‘best practice’ (BP) and a ‘business as usual’
(BAU) scenario, from an environmental and financial perspective. An integrated
Life Cycle Costing and Life Cycle Assessment was performed to quantify and
compare the environmental implications and cost-effectiveness of the scenarios.
The scenarios are based on field data collected in the BP demolition of a building
located in Almere, the Netherlands. The BP alternatives favor the reuse of retrieved
building components and the upcycling of concrete rubble, over general recycling
