A tool was developed for life cycle assessment of
cements. This tool aids the manufacturer to consider
environmental aspects in product development and
environmental reporting (for example environmental
product declaration). Attention was paid especially to
the energy efficiency in the manufacturing processes.
This affects not only energy use but also environmental
impacts such as the carbon footprint.
Cement is an essential material increasingly needed in
the production of concrete structures, buildings and the
modern infrastructure. However, the production of cement
is an energy-intensive process which requires a lot of
fuels and releases process emissions, especially CO2 in
the calcination process. On the other hand, as
calcination is an inevitable process in cement
production, attention should be given to energy use -
especially the use of recovered energy and combustible
wastes. Manufacturing process optimisation and life cycle
management are the key issues with regard to lowering
environmental impacts caused by cement production.
Cement industry belongs to the EU's emission trade
systems; they must track and report the CO2 emissions
annually. The role of manufacturer is also to identify
and improve the CO2 and other environmental impacts
incurred by production processes. This can happen with
the help of life cycle assessment tool, target-setting,
process development and monitoring. The LCA result should
be provided for designers, contractors, and users. This
information aids them to design eco-efficient use of
products and buildings.
