|[en] This study performs the environmental product declarations for three Belgian mineral products, two granite and one sandstone paving. Both main goals of this work were to obtain Belgian environmental product declarations to strengthen existing databases and to get similar information for their Asian counterparts. Indeed, competition with China for bluestone products and with India for sandstone pavement is very important due to very competitive prices despite their foreign origin and possibly higher induced environmental impacts.
Environmental product declarations of Belgian bluestone and sandstone products were conducted in accordance with the ISO standards and following the stand-ard NF P 01-010. CML 2001 method was used to obtain environmental impacts for ten categories as climate change, acidification, abiotic resources depletion, etc. Boundaries of the Belgian systems are the same and the life cycle assessment comprises all steps from the extraction of minerals to the implementation on site. Use and end of life steps were neglected due to the low required maintenance and the inert nature of the paving. For Asian products, the analysis is reduced to the transportation of the functional unit, mainly due to the lack of reliable data.
This work highlights the negative effect of long distance transportation of heavy and non-energetic products. Indeed, the environmental impacts of the sole transport of Asian products are at least as important as those obtained for the whole life cycle of Belgian products, whatever the category taken into account (climate change, acidification, air pollution, etc.).
CML 2001 methodology was successfully applied to these five studies about three Belgian products and two abroad transportation steps. Comparison of the 5 corresponding environmental product declarations permits to highlight the importance of the transport on environment and to promote, supposing equal performance, local prod-ucts in a more environmental-friendly point of view.
