Significance In the past decade, sporadic shortages of metals and metalloids crucial to modern technology have inspired attempts determine relative “criticality” various materials as a guide scientists product designers. The variety methodologies that been used for this purpose (predictably) resulted in widely varying results, which are therefore little use. present study, we develop comprehensive, flexible, transparent approach apply 62 metalloids. We find most concern tend be those with...
We have assembled extensive information on the cradle-to-gate environmental burdens of 63 metals in their major use forms, and illustrated interconnectedness metal production systems. Related cumulative energy use, global warming potential, human health implications ecosystem damage are estimated by life cycle stage (i.e., mining, purification, refining). For some elements, these first estimates impacts reported literature. show that, if compared a per kilogram basis, platinum group gold...
The concept of a circular economy (CE) is gaining increasing attention from policy makers, industry, and academia. There rapidly evolving debate on definitions, limitations, the contribution to wider sustainability agenda, need for indicators assess effectiveness measures at larger scales. Herein, we present framework comprehensive economy-wide biophysical assessment CE, utilizing systematically linking official statistics resource extraction use waste flows in mass-balanced approach. This...
Raw materials form the basis of Europe's economy to ensure jobs and competitiveness, they are essential for maintaining improving quality life. Although all raw important, some them more concern than others, thus list critical (CRMs) EU, underlying European Commission (EC) criticality assessment methodology, key instruments in context EU policy. For next update CRMs 2017, EC is considering apply overall methodology already used 2011 2014, but with modifications. Keeping same methodological...
Because modern technology depends on reliable supplies of a wide variety materials and because increasing concern about those supplies, comprehensive methodology was created to quantify the degree criticality metals periodic table. In this paper, we apply iron several its main alloying elements (i.e., vanadium, chromium, manganese, niobium). These represent basic any industrial society are vital for national security economic well-being. Assessments relating dimensions - supply risk,...
Summary Concerns about the future availability and continuity of metal supplies have triggered research efforts to define assess criticality. In this study, we apply a comprehensive methodology elements geological zinc, tin, lead family: zinc (Zn); germanium (Ge); cadmium (Cd); indium (In); tin (Sn); (Pb). Zn, Sn, Pb played important roles in various technological sectors for centuries, whereas Ge, Cd, are by‐product metals that increasingly utilized emerging strategic technologies....
The characterization of elemental cycles has a rich history in biogeochemistry. Well known examples include the global carbon cycle, or 'grand nutrients' nitrogen, phosphorus, and sulfur. More recently, efforts have increased to better understand natural cycling technology critical elements (TCEs), i.e. with high supply risk economic importance EU. On other hand, tools such as material-flow analysis (MFA) can help how substances goods are transported accumulated man-made technological...
This paper brings a discussion on the current state-of-the-art in criticality assessment an international context. It analyzes status of resource concepts and their calculation methods. The practice often exhibits common two-axis framework but way two axes are further operationalized shows heterogeneous approaches. Apart from as key element assessment, scope materials, role substitution, delineation supply chain data, indicator selection addressed elements. abovementioned is approached...
Modern technology makes use of a variety materials to allow for its proper functioning. To explore in detail the relationships connecting products that require them, we map supply chains five product platforms (a cadmium telluride solar cell, germanium turbine blade, lead acid battery, and hard drive (HD) magnet) using data ontology specifies chain actors (nodes) linkages (e.g., material exchange contractual relationships) among them. We then propose set network indicators (product...
Based on the combination of U.S. economic input-output table and stocks flows framework for characterizing anthropogenic metal cycles, this study presents a methodology building material flow networks bulk metals in economy applies it to aluminum. The results, which we term Input-Output Material Flow Networks (IO-MFNs), achieve complete picture aluminum entire any chosen industrial sector (illustrated Automobile Manufacturing sector). results are compared with information from our former...
Metals have strongly contributed to the development of human society. Today, large amounts and various metals are utilized in a wide variety products. rarely used individually but mostly together with other form alloys and/or combinational uses. This study reveals intersectoral flows by means input-output (IO) based material flow analysis (MFA). Using 2007 United States IO table, we calculate eight (i.e., manganese, chromium, nickel, molybdenum, niobium, vanadium, tungsten, cobalt)...
Summary Evaluating metal criticality is a topic that addresses future metals supply and has inspired research in corporations, academic institutions, governments. In this article, we apply comprehensive methodology to seven specialty metals—scandium (Sc), strontium (Sr), antimony (Sb), barium (Ba), mercury (Hg), thallium (Tl), bismuth (Bi)—at the national global levels for 2008. The results are presented along with uncertainty estimates three‐dimensional “criticality space” comprised of risk...
Metals are used in numerous products and sourced via increasingly global complex supply chains. Monetary input–output tables (MIOT) network analysis can be applied to intersectoral chains analyze structural aspects. We first provide a concise review of the literature related MIOTs. On basis physical table (PIOT) aluminum United States economy 2007, we identify key sectors discuss overall topology using tools analysis. Sectors highly dependent on metal product inputs or sales identified...
This is a prescriptive document containing the guidelines and ‘ready-to-apply' methodology for EU criticality assessment revision of list critical raw materials (CRM) EU. These synthesised build on used to establish lists CRM in 2011 2014 integrate methodological improvements identified by European Commission project ‘Assessment materials', close consultation with ad hoc working group ‘Defining materials'. Additional information regarding methodology, including justification discussion, can...
With the goal to move society toward less reliance on fossil fuels and mitigation of climate change, there is increasing interest investment in bioenergy sector. However, current growth patterns may, long term, only be met through an expansion global arable land at expense natural ecosystems competition with food Increasing thermal energy recovery from solid waste reduces dependence fossil- biobased production while enhancing landfill diversion. Using inventory data pilot processes, this...
Episodic supply shortages of metals and unsettling predictions potential constraints in the future have led to a series recent criticality evaluations.
