Article
This article critically reviews LCAs of tailings management, including disposal, use in construction materials and reprocessing for metal recovery. It explores 28 publications considering goal and scope definition, Life Cycle Inventory (LCI), impact assessment (IA), and interpretation. Lessons learnt are discussed: i) tailings final disposal is an...

The consumption of most metals continues to rise following ever-increasing population growth, affluence and technological development. Sustainability considerations urge greater resource efficiency and retention of metals in the economy. We model the fate of a yearly cohort of 61 extracted metals over time and identify where losses are expected to...
Article
Extracting mineral ores to produce mineral concentrates and finally metals that enter the value chains of different sectors is a waste intensive activity. In particular, mineral processing activities generate yearly and globally several billion tons of wastes called tailings. Tailings storage is associated with significant environmental risks due t...

Purpose We observe a methodological gap for assessing impacts within the Area of Protection (AoP) Natural Resources in LCA with regard to concerns about the accessibility to raw materials. Adding criticality considerations as a complement to environmental LCA addresses abiotic resources accessibility. We present a study that integrates and applies...
Article
Important advances have been made to define the multiple impact pathways relating mineral resource use to the area of protection (AoP) natural resources in life cycle assessment (LCA). Yet, the link between stakeholders’ interests and the aspects relevant to resource use as addressed by existing impact assessment methods has so far only marginally...
Article
Full-text available
Purpose Mining of raw materials have both positive (e.g., creation of values and jobs along their supply chains and the supply chains they enter) and negative social impacts (e.g., affecting safe and healthy living conditions of the local community or through the risk of corruption). A new mining paradigm, small-scale “switch-on switch-off” (SOSO)...
Article
As one of the largest energy consumers and greenhouse gas (GHG) emitters, the mining industry is switching to renewable energy to help reduce its energy and environmental impacts. There are already renewable energy systems (RES) in operation at large-scale mines. However, for off-grid small-scale mining operations, conventional diesel generators ar...
Chapter
The effects of the quantities of waste and emissions on the environment are captured in the form of “environmental footprints”. For metals in particular, disparities in the locations of extraction, processing, and use also lead to disparities in the geography of the footprints. This chapter shows how multi‐regional input–output models provide infor...
Article
A switch on-switch off (SOSO) approach to mining relies on an integrated modular and mobile plant. It is appropriate for rapid start-up and cessation of production from ore deposits that have economic viability dependent on fluctuating commodity prices. This study aims at assessing the environmental performance of the SOSO approach in a life cycle...
Article
The dissipation of metals leads to potential environmental impacts, usually evaluated for product systems with life cycle assessment. Dissipative flows of metals become inaccessible for future users, going against the common goal of a more circular economy. Therefore, they should be addressed in life cycle impact assessment (LCIA) in the area of pr...
Chapter
L’augmentation constante de la consommation de ressources minérales ainsi que la prise de conscience croissante des nuisances occasionnées par leur exploitation provoquent une profonde inquiétude au sein de la communauté scientifique. Cette inquiétude est d’autant plus justifiée que la transition énergétique va aggraver la pression exercée sur ces...
Article
All economies rely today on metal use either in the construction or energy sectors or in more advanced technology sectors. Nevertheless, not all countries have mining industries, which implies that these countries need to import primary metal concentrates and semi-finished goods containing metals to fulfill their final consumption. By importing the...
Article
This study aims at assessing the environmental performances of the French MSW incineration sector in a life cycle perspective, considering nine midpoint impact categories. It is the first application of the WILCI tool, dedicated to the LCA of MSW incineration in the French situation (Beylot et al., 2017). The model is primarily based on operational...
Article
In France, significant investments regarding renewable energy power plants will be required in future years in order to attain targets set by French and European regulations. This study aims i) at quantifying the requirements for steel, aluminium, copper (among the most impactful metal productions with respect to climate change in the world) and co...
Chapter
Producing a product, providing a service, or making a decision that affects the way products are produced or consumed has repercussions on an intricate and wide range of activities. Life cycle assessment (LCA) aims to give a measure of the environmental potential impacts associated with a given product, service, or decision by accounting for the im...
Technical Report
Full-text available
WILCI (for Waste incineration life cycle inventory tool) is an Excel-based tool dedicated to the life cycle assessment (LCA) of municipal solid waste (MSW) incineration in the French situation. In view of the similarities between French and other European MSW management systems, it can be considered a robust tool to perform the LCA of MSW incinerat...
Article
Life cycle inventory data have multiple sources of uncertainty. These data uncertainties are often modeled using probability density functions, and in the ecoinvent database the lognormal distribution is used by default to model exchange uncertainty values. The aim of this article is to systematically measure the effect of this default distribution...
Article
Full-text available
Purpose Life cycle inventory (LCI) databases provide generic data on exchange values associated with unit processes. The “ecoinvent” LCI database estimates the uncertainty of all exchange values through the application of the so-called pedigree approach. In the first release of the database, the used uncertainty factors were based on experts’ judgm...
Article
Purpose Data used in life cycle inventories are uncertain (Ciroth et al. Int J Life Cycle Assess 9(4):216–226, 2004). The ecoinvent LCI database considers uncertainty on exchange values. The default approach applied to quantify uncertainty in ecoinvent is a semi-quantitative approach based on the use of a pedigree matrix; it considers two types of...
Article
Purpose Ecoinvent applies a method for estimation of default standard deviations for flow data from characteristics of these flows and the respective processes that are turned into uncertainty factors in a pedigree matrix, starting from qualitative assessments. The uncertainty factors are aggregated to the standard deviation. This approach allows c...

The decade 2005-2014 has been set by UNESCO as the United Nations decade of Education forSustainable Development (SD) [1]. As graduate studentsof this decade, our vision of SD teaching targets inengineering concerns the development of attitudes to assess projects and related impacts in a systemic way, the development of transversal skills, and the...

Project
The goal of this PhD research project is to develop an indicator to take the dissipation of non-energetic abiotic resources into account in life cycle assessment. The area of protection natural resources, the dissipation of mineral resources and ecosystem services are all trendy topics in the life cycle assessment community. The proposition should hence be coherent with methodological developments for the other natural resources and ecosystem services as well.
