“…This has been the basis for several LCIA methods for resources (e.g., Steen, 1999;Goedkoop and Spriensma, 2000). However, as argued by Weidema et al (2005), if current resource use leads to changes in the environmental interventions of future extractions, this should be modelled in the Inventory Analysis, at least in a consequential LCA, and not in the LCIA. If this is done, it will also lead to a discussion on the time issues in parallel to time in relation to landfilling discussed below (Section 5).…”

“…For LCIA, various proposals have been made for impact categories and category indicators for abiotic resources (Lindfors et al, 1995;Lee, 1998;Guinée, 2002;Finnveden, 2005;Weidema et al, 2005;Brent and Hietkamp, 2006;Steen, 2006). In principle, there are four types of indicators based on the following: (a) energy or mass; (b) relation of use to deposits (i.e.…”

“…The grave‐to‐cradle approach presented fills in a key element of the framework methodologies based on the concept of resource functionality proposed by Stewart and Weidema (). The main aim of their framework is to define the necessary and sufficient set of information required to quantify the effects of resources depletion for all the resource categories considered.…”

Keywords:exergy industrial ecology life cycle assessment (LCA) minerals mining nickel Supporting information is available on the JIE Web site SummaryLife cycle assessment (LCA) is a promising tool in the pursuit of sustainable mining. However, the accounting methodologies used in LCA for abiotic resource depletion still have some shortcomings and need to be improved. In this article a new thermodynamic approach is presented for the evaluation of the depletion of nonfuel minerals. The method is based on quantifying the exergy costs required to replace the extracted minerals with current available technologies, from a completely degraded state in what we term "Thanatia" to the conditions currently found in nature. Thanatia is an estimated reference model of a commercial end of the planet, where all resources have been extracted and dispersed, and all fossil fuels have been burned. Mineral deposits constitute an exergy bonus that nature gives us for free by providing minerals in a concentrated state and not dispersed in the crust. The exergy replacement costs provide a measure of the bonus lost through extraction. This approach allows performing an LCA by including a new stage in the analysis: namely the grave to cradle path. The methodology is explained through the case study of nickel depletion.
