“…Moreover, as each ore corresponds to specific geological, exploitation and processing conditions, environmental impacts are different for each mineral good extracted, requiring specific studies for each case (Norgate and Haque, 2010). This is particularly true for operations with iron ore, where existing studies show the mining processes reduced to a step within the steel production system (Li et al, 2002;Norgate et al, 2007;Bieda, 2012).…”

“…The difference between Worldsteel, Ecoinvent and our study for acidification, global warming potential and photochemical oxidation can be explained by the fact that EAF is used at more than 95 % in our study. Actually, Ecoinvent generic European value considers that only 37 % of reinforcing steel is produced throughout EAF and it is known that EAF is less energy and fossil resources intensive than BF (Li et al 2002). For Worldsteel LCA data, the exact proportion between EAF and BF is not specified in the ELCD website (2012).…”

Purpose Environmental data for steel products are generally proposed at a continental or a global scale. The question we are tackling here is: does the fact that steel as a global market necessarily reduces the need for national data? Methods In this study, the environmental impact of reinforcing steel sold in France is evaluated. To do so, a specific environmental inventory is adapted from Ecoinvent database. CML method is used for impact calculation and both methods "recycled content" as well as "end of life recycling approach" are tested. Results and discussion This study shows that there is a specificity of reinforcing steel products sold in France compared to European value. It is due to the fact that reinforcing steel is mainly made with recycled steel as the market growth for construction product in France is limited allowing a very high recycled content. This result is not sensitive neither to the allocation method used for recycling (cut-off approach or system expansion) nor to transport distance and electricity country mix used. Conclusions The result of this study can be used with confidence in every construction site work located on the French territory. Furthermore, the present study advocates for an adaptation of global database to local context defined by a specific industrial sector and a geographic region even for product such as steel that may be considered as a first approximation as a global product.

“…Now, more than 10 years later, there has been remarkable progress with many publications on different subjects. Current research in China covers a lot of areas including regional life cycle impact assessment (LCIA) methodology of abiotic resources (Gao et al 2009a, b, c), land use (Liu et al 2010), the Chinese life cycle inventory (LCI) database (Gong et al 2006), as well as typical case studies such as power generation (Di et al 2007), iron and steel (Li et al 2002), magnesium (Gao et al 2009a, b, c), construction (Wu et al 2012), continuous pad-dyeing technology for cotton fabrics (Yuan et al 2013), aseptic packaging waste management (Xie et al 2013), desktop personal computers (PCs) (Song et al 2013), polymers (Hong and Li 2012), titanium (Liao et al 2012), and so on. In addition, a symposium focused on materials LCA (MLCA) and ecomaterials has been held biennially in China as part of the IUMRS international conference on advanced materials.…”
