Critical mineral raw materials
Since 2011, the European Commission assesses a 3-year list of Critical Raw Materials (CRMs) for the EU economy within its Raw Materials Initiative. To date, 14 CRMs were identified in 2011, 20 in 2014 and 27 in 2017.
These materials are mainly used in energy transition and digital technologies.
European lists of Critical Raw Materials
Critical materials have been defined as "raw materials for which there are no viable substitutes with current technologies, which most consumer countries are dependent on importing, and whose supply is dominated by one or a few producers".
Several factors may combine together to make a raw material (mineral or not) a critical resource. These may include the following:
- A ceiling on production: when the raw material reaches its Hubbert peak
- A drop in known deposits
- A decline in the ratio of production from the biggest deposits to production from smaller deposits, since the largest deposits supply most of a raw material's production
- Inefficient price system: when the increase in the price of a raw material does not result in a proportional resulting increase in its production
- Costs of extraction (money or effort) increase over time, as extraction becomes more difficult.
List of relevant minerals and other commodities
There are many issues about these resources and they concern a large number of people and human activities. It is possible to distinguish:
- Economic: the price of metals increases when their scarcity or inaccessibility increases, and not only according to demand for them. As part of transition management, the circular economy invites citizens to recycle these resources as well as to save them and/or to replace them with alternatives when it is possible; that could be greatly facilitated with the generalization of ecotax and eco-design.
- Geostrategic: These rare products are necessary for computer and other communications equipment and can themselves be the subject of armed conflict or simply provide armed conflict with a source of funding. Both coltan and blood diamonds have been examples of the resource curse that plagues some parts of Africa.
- Social: Increasing globalization and mobility of people, means that telecoms and social networks depend more and more on the availability of these resources.
- Health: Several critical metals or minerals are toxic or reprotoxic. Paradoxically, some cytotoxins are used in cancer therapy (and then also improperly discarded although really dangerous for the environment; the average cost of the treatment of a lung cancer varies between 20,000 and 27,000 euros). Thus, toxic and cancer-causing platinum is also widely used in cancer chemotherapy in the form of carboplatin and cisplatin, both cytotoxins combined with other molecules, including for example gemcitabine (GEM), vinorelbine (VIN), docetaxel (DOC), and paclitaxel (PAC).
- Energy: Production of these metals and their compounds requires a significant and increasing amount of energy, and when they become rarer, it is necessary to search deeper for them, and the further mineral recovered is sometimes less condensed than previous production had been. In 2012, from 7 to 8% of all the energy used in the world was used to extract these minerals.
- Environmental: The mines degrade the environment. The dispersion of minerals and toxic non-recycled metals degrades it too. Furthermore, the magnets in electrical motors, or wind and water turbines, as well as some components of solar panels also need many of these same minerals or rare metals.
According to the United Nations (2011, and ien 2013), as the demand for rare metals will quickly exceed the consumed tonnage in 2013, it is urgent and priority should be placed on recycling rare metals with a worldwide production lower than 100 000 t/year, in order to conserve natural resources and energy. However, this measure will not be enough. Planned obsolescence of products which contain these metals should be limited, and all elements inside computers, mobile phones or other electronic objects found in electronic waste should be recycled. This involves looking for eco-designed alternatives, and changes in consumer behavior in favor of selective sorting aimed at an almost total recycling of these metals.
In the same time, the demand for these materials "has to be optimized or reduced", insist Ernst Ulrich von Weizsäcker and Ashok Khosla, co-presidents of the International Resource Panel created in 2007 by the United States, and hosted by the UNEP) to analyse the impact of resource use on the environment in 2013.
Europe alone produced about 12 million tons of metallic wastes in 2012, and this amount tended to grow more than 4% a year (faster than municipal waste). However, fewer than 20 metals, of the 60 studied by experts of the UNEP, were recycled to more than 50% in the world. 34 compounds were recycled at lower than 1% of the total discarded as trash.
Information about the location of deposits of rare metals is scarce. The US DOE created the Critical Materials Institute in 2013, intended to focus on finding and commercializing ways to reduce reliance on the critical materials essential for American competitiveness in the clean energy technologies.
A counter-perspective is represented by Professor Indra Overland, who has heavily criticised analyses that posit critical materials for renewable energy as a bottleneck for transition to renewable energy and/or as a source of geopolitical tension. Such analyses ignore the fact that unlike fossil fuels, most critical minerals can be recycled and technological innovation will enable better exploration, extraction, and processing. Especially the importance of rare earth elements for renewable energy applications has been exaggerated, according to Overland. Neodymium magnets are only needed for a rare type of wind turbine that uses permanent magnets. Even for offshore wind developments it is not clear whether permanent magnets will be much needed.

- The fertilizer industry used about 85% of U.S. potash sales, and the remainder was used for chemical and industrial applications. About 75% of the potash produced was SOPM and SOP, which are required by certain crops and soils. MOP accounted for the remaining 25% of production and was used for agricultural and chemical applications.

- The cellular metabolism of all life requires phosphorus; humans need between 700 and 1250 milligrams (mg) a day. Traditional farming practices used human and animal excrement as fertiliser for plants, but today most of this excrement is not collected and ends up in watercourses and in the sea. This forces the use of phosphorus from fossil excrements (old guano) or from minerals. It seems that 6,056 kg of phosphorus are introduced every second (191 millions of tons every year); this could lead to a peak production by 2030, and then to a phosphate shortage, or worse, a large-scale famine.
