A proposed new ASTM International standard describes a method for calculating the length of time that a non-fuel mineral commodity can be extracted from its reserves and resources, for purposes of environmental product declarations (EPD) and life cycle analyses (LCA). ASTM WK31671, Practice for Calculation of the Resource Depletion Potential of Mineral Commodities, is being developed by Subcommittee E60.80 on General Sustainability Standards, part of ASTM International Committee E60 on Sustainability.
“ASTM WK31671 will be used for a technically accurate assessment of the length of time that extraction will occur from a mineral commodity resource before depletion when recycling and substitutes are taken into account,” says Harold Taylor, president, Basic Mines and chair of the E60.80 task group that is developing the proposed standard.
Anyone preparing an EPD or LCA will be able to use the proposed standard, once approved, to examine the following factors, applicable to a mineral commodity, which can affect the life of its world resource:
• Total amount of reserves and resources;
• Amount extracted annually;
• Amount annually recycled; and
• Amount annually displaced by substitutes.
Taylor notes that interested participants, particularly those who deal with iron and steel, aluminum, copper, zinc, fertilizers, ceramics and other mineral commodities are encouraged to join the task group currently developing ASTM WK31671.
