Sustainable Production
Production processes are relevant contributors to the global carbon balance and to environmental pollution - cement production e.g. induces 4% of global CO2-emissions. Consequently, the global increase in wealth demands for more efficient and less polluting production processes. Assessing overall benefits caused by single process improvements is however complex, as unwanted effects up- and downstream in the process chain might occur. Goal of the NAREP-module “Sustainable Production” is therefore the joint research on technical key process improvement combined with life-cycle based technology assessment.

Cement production (F. Winnefeld):
Substitution of  tricalcium silicate (3CaO•SiO2, C3S) by calcium sulfoaluminate, alkali activated slags, or fly ash

Road construction (M. Partl):
Using low quality, marginal materials (fly ash, sand, volcanic aggregates); Energy-efficient road construction; Reuse of pavement materials

Building components (H.-J. Althaus):
Reduction of impacts in production and use phase

Life Cycle Assessment (R. Zah, H.-J. Althaus):
Carbon footprints, environmental impacts, water footprint; Integration of indirect effects; Development of „Quick Check Tools“ (www.sqcb.org)

Scarce Metals Assessment (P. Wäger):
Geological, economical, geo-political, technological and environmental scarcity assessment

Evaluation of End-of-Life Options (R. Widmer, M. Schluep):
Global modelling of eWaste streams and recycling options
