- CRMs in Products
- New technologies, products and other advancements are key to the continued success and
- development of the European economy.
- To achieve this, the supply of raw materials is crucial.
- However, the supply of raw materials which is the lifeblood of many of today’s high-tech
- industries, is increasingly under pressure.
- In the last five years, about 80% of companies in the high tech sector have dealt with serious
- delivery issues concerning vital raw materials and semi-finished products.
- As a means of quantifying this problem, the European Commission has created a list of critical
- raw materials, or CRMs for short, which is subject to a regular review and update.
- Critical Raw Materials are those raw materials which are economically and strategically
- important for the European economy, but have a high-risk associated with their supply.
- These materials are ‘critical’ for key industry sectors and therefore the sustainable functioning
- of the economy.
- These materials are used in diverse fields such as environmental technologies, consumer
- electronics, health-care, steel-making, defence, space exploration, and aviation, to name but
- a few.
- It is important to note that these materials are not classified as ‘critical’ because these
- materials are considered scarce, rather they are classified as ‘critical’ because: they have a
- significant economic importance for key sectors in the European economy, such as
- electronics, environmental technologies, automotive, aerospace, defence and health.
- For example, a smartphone might contain up to 50 different kinds of metals, all of which
- contribute to its small size, light weight and functionality.
- Critical raw materials are closely linked to cleaner technologies.
- They are irreplaceable in solar panels, wind turbines, electric vehicles, and energy-efficient
- lighting.
- The EU CRM policy is especially relevant for defence as it is a multi-product and high-tech
- sector.
- To be considered critical they also have a high-supply risk due to the very-high import
- dependence and high concentration of set critical raw materials in particular countries, based
- on their governance performance.
- There must also be a lack of viable substitutes, due to the very unique and reliable properties
- of these materials.
- The main parameters used to determine if a material is a CRM for the EU are: Economic
- importance – an attempt to measure the importance of a material for the EU economy in
- terms of end-user applications and the value added (VA) of corresponding EU manufacturing
- sectors.
- Supply risk - reflects the risk of a disruption in the EU supply of the material.
- It is based on the concentration of primary supply from raw materials producing countries,
- considering their governance performance and trade aspects, poor end of life recycling rates,
- and low potential for substitution.
- The EU’s industry and economy are reliant on international markets to provide access to many
- important raw materials since they are produced and supplied by countries outside of the EU.
- Although the domestic production of certain critical raw materials exists in the EU, in most
- cases the EU is dependent on imports from non-EU countries.
- China is the major supplier of critical raw materials, accounting for 70% of the global supply
- and 62% of the supply to the EU.
- Examples include: rare earth elements, magnesium, and antimony.
- Brazil for niobium, USA for beryllium and helium, Russia for palladium and South Africa for
- iridium, platinum, rhodium and ruthenium are also important producers of critical raw
- materials.
- There have been 3 revisions of the CRM list published thus far: - in 2010, 2014 and most
- recently in 2017.
- The current revision of the list identifies 27 materials which are now considered critical by the
- Commission.
- These are now shown on the screen.
- Because of their prominence in the critical raw materials list, this MOOC focuses on metals.
- Mining CRM
- Welcome to this lesson, where I will explain you geopolitical and environmental issues
- associated with the mining of critical raw materials.
- A mineral deposit contains one or more commodities, which may be extracted depending on
- the economic considerations.
- Few critical raw materials occur on their own, such as platinum group metals in South Africa,
- which is the leading global producer of these metals.
- Otherwise, platinum group metals occur together with base metals like copper and nickel and
- is rather a by-product than main commodity.
- Many other critical raw materials are extracted as by-products of major metal or mineral
- mining operations.
- These include for example bismuth, cobalt and gallium, which are extracted together with
- gold, nickel, aluminium, etc.
- Because of this, the extraction of critical raw materials is often dependant on the development
- of major projects and can take several years.
- For these commodities, the production bottleneck is usually further down the value chain.
- They are typically extracted from the mine in raw ore form, but are not recovered at the
- refineries or smelters, due to the lack of economic incentive or simple technology.
- Today’s increasing demand for digital, IT, automotive and hi-tech products results in an
- increasing demand for critical raw materials, which puts further stress on a scarce finite
- resource.
- Many European countries are strongly dependent on the import of these materials from
- abroad.
- Some critical raw materials are located in parts of the world, which are politically and
- economically unstable and do not have systems in place that would guarantee responsible
- sourcing of these materials.
- Hence, the rising demand combined with localisation of critical raw materials in such regions
- becomes a major political and economic issue.
- For example, China is a top producer of 18 out of 27 critical raw materials, while Europe is a
- top producer for only 1 critical raw material.
- Next to China, the largest global suppliers are the USA, Brazil, Russia and the Democratic
- Republic of Congo.
- To further exacerbate the problem, resource rich countries are very protective of their
- resources and want to keep them for their own development.
- Measures and decisions undertaken in these countries can cause serious distortions on the
- world market and put many industrial sectors at a competitive disadvantage.
- In the next lessons, you will learn what EU is doing to counterbalance these measures.
- The availability of raw materials is not determined solely by geopolitics.
- Another important factor that needs to be taken into account are the environmental risks of
- mining.
- These environmental problems influence not only the social acceptance of mining, but can
- also seriously affect the cost of raw materials.
- A good example is price rise for nickel, after more than 20 mines in the Philippines were shut
- down, due to environmental problems in February 2017.
- These mines were closed because they were polluting rivers, rice fields and watersheds with
- red nickel laterite.
- Another location affected by environmental issues associated with mining is Papua New
- Guinea.
- Here, the Ok Tedi copper and gold mine is located at the headwaters of Ok Tedi River in Papua
- New Guinea.
- It is one of the largest copper mines in the world.
- Initially, the government demanded that the river must be protected from the mine tailings
- by a dam in order for it to be operational.
- Tailings are the materials left over after the process of separating the valuable fraction from
- the uneconomic fraction of an ore.
- Tailings are usually unstable and damage the land and water environment by releasing toxic
- substances, like arsenic and mercury, and by acid drainage.
- Unfortunately, a landslide destroyed the tailings dam and afterwards the mine operators
- successfully continued operating without building a new dam.
- This means that thousands to millions of tonnes of waste rock, tailings and tailing fine sand
- were now discharged annually into the river.
- The obviously ruinous environmental consequences of this decision were tragic for the river
- ecosystem as well as for the people whose livelihood depended on the river.
- As you can see, operation of mines results in emissions to air and water, but building a mine
- carries also a significant ecological burden.
- Surrounding forests are cut, rivers polluted and local fauna and flora disturbed as their
- biological niches are eliminated.
- Next to that, there are also social challenges related to the operation of mines.
- Very often mines are built in remote areas in developing countries, with little social control.
- Forced labour, poor health and safety conditions, child labour and corruption are not
- uncommon in these regions.
- The best way to stop these unethical practices, is if the major consumers of certain metals or
- minerals impose the sustainable procurement rules on their suppliers.
- A good example is Umicore, which is the first company in the world to have introduced a
- Sustainable Procurement Framework on Cobalt.
- 1.4 Materials shortage?
- What is materials shortage?
- In this video we define materials shortage as the lack of a material at a certain price to make
- it an economically viable product.
- That means that if there is a shortage of a material to make a product, two things could
- happen simultaneously.
- The first one is that the price will increase to a level where new exploration is economically
- feasible.
- In other words; a higher price for the material makes more expensive exploration possible.
- There is more money around to dig deeper.
- The second thing that could happen is that some products are getting too expensive and will
- not be made, or a substitute material will be used, if possible.
- This outlook on possibilities does not include the dynamics around materials exploration.
- It takes about 3 to 5 years to open a mine on land and make it operational.
- The required investments are quite significant.
- Since 2010 the prices of different critical raw materials have been fluctuating.
- In 2011, for example, the prices of neodymium, which is used in wind turbine production,
- went up 6 fold.
- These turbulent price fluctuations make large investment in mining on land or at the ocean
- bottom very risky.
- It also increases the supply risks.
- The world population is expected to increase from 7 billion in 2017 to 9 billion by 2037,
- according to the United Nations Population Division.
- This organization expects the 10 billion mark to be met in 2055.
- Such a population increase will obviously increase the demand for materials and CRMs, as
- more people will buy more products, necessitating more materials.
- Furthermore, material demand has sharply increased due to the fast growth of consumers in
- large emerging economies such as China and India.
- This sharp increase puts additional pressure on the materials demand.
- Many critical raw materials are used in high tech devices such as smartphones.
- A shortage of these critical raw materials due to any of the aforementioned factors could
- hamper the further development of high tech devices for the high tech economy.
- Another important undertaking could also be hampered by such a shortage; the development
- of a zero carbon economy.
- In order to achieve a zero carbon economy, new high tech products are necessary for the
- production of zero carbon electricity, such as solar panels and wind turbines.
- Current crystalline solar panels need silver for their contacts.
- The new thin film solar panels need Germanium amongst others.
- Wind turbines need neodymium for their dynamo’s.
- Other products have to be adapted for this carbon neutral economy, such as cars.
- We have to switch from gasoline or diesel to electric cars.
- For these electric cars neodymium is necessary for the electric motors.
- For a zero carbon economy we have to switch to more energy efficient products such as
- energy efficient LED-lights.
- LED lights need gallium and indium.
- The necessity of all these materials for high tech products to make a zero carbon economy
- possible, can drive up the price of critical raw materials.
- It can also slow down the development of the economic viability of zero carbon technology,
- that is so important to stop climate change.
- To reduce this increasing pressure on material mining, we can recycle the products we now
- thoughtlessly discard, such as mobile telephones and laptops.
- Although recycling technology is developing at a steady pace, the recycling rate of many
- critical raw metals is quite low.
- According to a study by the Oeko-institute from Darmstad, Germany in 2012, the recycling
- rate of silver for example was above 50%, but for other critical raw metals needed for our zero
- carbon economy, such as neodymium and gallium, the recycling rate was less than 1 percent.
- And even if more and more critical raw materials could be recycled, the sheer increase in
- demand for new products by a growing number of consumers with a spending power coming
- close to EU or US citizens, puts a lot of pressure on winning primary materials.
- To counter this pressure closing the loop of these materials, a longer lifetime of products, and
- substitution of materials amongst others, is of significant importance.
- In the coming modules we show you all kinds of idea’s how to do this.
- EU Policy
- In this lesson, I will introduce some elements of the EU policy, which aim to ensure the supply
- of critical raw materials in Europe.
- Today, the world is facing a tremendous challenge related to resource supply.
- It threatens our way of life - while some resources, such as water, are vital for all forms of life,
- others became essential to maintain our current standard of living.
- This is the case for metals and minerals, which are used in a wide range of applications, from
- the production of phones and computers, to the growing of our food.
- The growth of the worldwide population, which is expected to reach 9.5 billion by 2050,
- results in an increased consumption of resources.
- The global consumption of materials increased by 60% from 1980 to 2008, and is expected to
- increase by almost 40% by 2030 compared to 2010, reaching 100 Giga tonnes per year.
- This increased resource consumption is also accompanied by an increase in the world average
- income induced by economic growth in non-OECD countries such as China and India.
- The European Union has to deal with this in the form of increasingly competitive use of
- resources, while ensuring good living conditions for its citizens.
- To this end, ensuring access to critical raw materials has become a priority.
- To tackle this challenge, the EU has developed two parallel strategies: improve the
- management of raw materials within the EU via the establishment of several policy
- instruments, and secure the supply of raw materials on global markets.
- The EU has developed several policies, starting in the early seventies with the waste
- management policies, which aimed to safely dispose waste streams and avoid the emissions
- of harmful substances, such as lead or copper, into the environment.
- In 2006, the waste hierarchy was introduced in the Waste Framework Directive and defines
- the prioritised set of measures and treatments, which member states should use in the
- treatment of waste.
- In order of precedence, these are: waste prevention, preparing for reuse, recycling, recovery
- and disposal.
- The waste hierarchy has resulted in a new wave of waste policies, which aim to improve the
- management of high value materials containing many critical raw materials.
- This is the case of the Batteries Directive and the Directive for Waste Electrical and Electronic
- Equipment, or WEEE.
- These directives define measures to establish schemes for high level of collection and
- recycling, and fix targets for collection and recycling activities.
- In parallel, the Eco-design Directive supports these measures for example by asking
- manufacturers to provide technical ‘information relevant for disassembly, recycling or
- disposal at end-of-life’ at the product level.
- Product-specific regulations have been put in place for example for computers, power
- transformers or ventilation units, which generally contain significant amounts of CRMs.
- The most recent measures implemented to tackle the challenge of resource supply are
- gathered in the EU action plan for the circular economy.
- In this action plan, critical raw materials are clearly presented as a priority for Europe.
- One example of such measure is the definition of European standards for material-efficient
- recycling of electronic waste, waste batteries and other complex end-of-life products.
- The European Commission also wants to improve the exchange of information between
- manufacturers and recyclers on electronic products and the sharing of best practice for the
- recovery of critical raw materials from mining waste and landfills.
- However, as you can see on this map, Europe is still highly dependent on the import of critical
- raw materials from non-EU countries and has to secure its supply on global markets.
- It is especially the case for rare-earth elements for which no recycling or substitution
- processes are currently commercially viable.
- The instability of some parts of the world and the impact of their relationship with the EU can
- threaten the supply of raw materials to the EU.
- To tackle this challenge, the EU has set up the EU Raw Material Diplomacy, which intends to
- reach out to non-EU countries through strategic partnerships set during missions for growth
- and policy dialogues.
- The aim is to maintain or create collaborations on raw materials production, trade and
- recycling.
- The EU has developed relations with countries, which are key actors for the supply of critical
- raw materials to the EU.
- Examples include Morocco, which provides 27% of the phosphate rock, and China, which
- provides 94% of the magnesium consumed in the EU.
- One challenge the EU is facing is that critical raw materials are often located in politically
- unstable countries where their trade can be used to finance armed groups, fuel human rights
- abuses, and support corruption and money laundering.
- Therefore, one aspect of EU policy is to ensure a responsible sourcing of materials.
- The new EU Conflict Minerals regulation which will come into force in 2021 will contribute to
- it by requiring EU companies to ensure they import selected minerals and metals from
- responsible and conflict-free sources only.
- So, Europe is taking action to ensure its supply of critical raw materials by encouraging their
- recovery and recycling within Europe and by maintaining or creating collaborations with key
- regions of the world where these materials are available.
- These measures are key to maintaining the current way of life of European citizens.
- People should also be aware that their consumption patterns directly contribute to this
- dependency on critical raw materials and could positively influence this dependency by
- switching towards more sustainable consumption.
- Current waste management
- Most of the critical raw materials are to be found in discarded electronic and electrical
- equipment (the double U triple EEE), in end-of-life vehicles and in metal scrap.
- Although the recycling rate of metal scrap is quite high, critical raw materials in alloys are not
- recovered.
- In most cases, there is separation at the scrap yard in generally used steel, stainless steel,
- copper, aluminium, and lead.
- But this separation is crude at best.
- Most of the critical raw metals are lost when melting the steel and other metals in the
- recycling process.
- In end-of-life vehicles there is a fair separation of steel and other metals such as aluminium,
- however the recovery of critical raw materials in the electronics or electro motors of a car, is
- considered economically not viable.
- Recyclable waste containing mostly mixed metals, such as WEEE, is first shredded.
- This is followed by the removal of steel and plastics.
- The mixture of non-ferrous metals is then sent to hydro- and/or pyro metallurgy.
- In hydro metallurgy, metals are dissolved in acids at low temperature, and in pyro metallurgy
- the metals are smelted at high temperature.
- For example Umicore in Belgium is specialized in retrieving metals using such processes and
- can currently retrieve 17 different metals from waste.
- However products such as electrical and electronic equipment contains more and more
- different critical raw materials such as Gallium and Indium, both having a recycling rate of less
- than one percent.
- Batteries are usually collected and treated separately.
- Batteries containing mercury are separated and the mercury is recovered.
- In 2016 about 10 and a half million tons of WEEE was generated in the EU, Norway and
- Switzerland.
- In that same year about 2 million tons of battery waste was generated in that area.
- As of 2019, every member state of the European Union has to make sure either 65% of electric
- and electronic equipment put on the market, or 85% of WEEE generated in that Member State
- must be recycled.
- The waste that is not recycled is landfilled, incinerated or exported illegally.
- When this waste is tossed in the bin for residual waste, it ends up on a landfill or in an
- incinerator.
- There are problems with landfilling with waste that contains metals, such as batteries or
- electric and electronic equipment.
- The major problem is that the critical raw materials in this waste dissolve into heavy metal
- oxides.
- When this is combined with organic material decomposing in the same landfill, organic acids
- are formed.
- These acids dissolve heavy metals forming metal ions, such as lead, cadmium, mercury,
- copper and tin-ions.
- These ions partially dissolve into the water in the landfill, forming a substance called
- “leachate”.
- When a landfill is not isolated from the surrounding environment, these heavy metals will
- pollute this environment.
- Therefore most modern landfills have a practically non-permeable bottom layer, as well as
- practically non-permeable concrete walls, or a rubber lining.
- You can compare such an isolated landfill to a bathtub.
- However, even this solution is not without risks - any concrete wall or rubber lining can fail
- over time and the heavy metals still can enter the surrounding environment.
- Therefore the leachate water in the landfill is pumped out so that the water level in the landfill
- is lower than the water level outside the landfill.
- Water can only enter the landfill, not leave the landfill.
- The leachate water is treated in a water treatment plant before being released back into the
- sewage system.
- In this water treatment plant the heavy metals are precipitated.
- In other countries such as the Netherlands combustible residual waste such as household
- waste or waste from offices is incinerated.
- An incinerator operates at a temperature of about 850 degrees Celsius.
- At this temperature some metals melt and are mixed with the slag, or oxidizes.
- Some of these of metals end up in the slag.
- In many cases ferrous and non-ferrous scrap is removed from the slag to give the slag
- acceptable properties for civil works and to have an extra financial income from the scrap.
- However in the slag, the tiny metals from WEEE cannot be removed - nor can oxidized metals
- and metals mixed with other slag particles.
- These metals will eventually leach out.
- In many countries the slag is landfilled.
- When slag is used for civil works, regulations apply to control the leaching of heavy metals.
- According to the European regulations, WEEE must be safely processed within the European
- Union.
- However, obsolete or non-functioning equipment has a market value in countries outside the
- European Union.
- Untested cell phones are worth at least 5 euros in Nigeria, whereas the same cell phone only
- has a material value of around one euro in Germany.
- It is estimated that old TV sets, which still work, generate 17 to 35 euros in Nigeria, while in
- Germany the treatment costs are higher than any income from sales of the recycled materials.
- The higher environmental standards for treatment in the EU has correspondingly higher cost
- for treatment or disposal.
- This results in a lot of illegal export of WEEE from the EU.
- This illegal export can offer significant income or savings to operators dealing with WEEE or ewaste.
- In addition, export to Asian countries has a low threshold due to the low transportation costs
- of containers going mostly back empty from Europe to South-East Asia.
- It is not only the potential financial gains which cause people to engage in this criminal trade.
- High unemployment rates can also encourage people to legally export e-waste, as it is rarely
- prosecuted by national authorities.
- The United Kingdom, the Netherlands and Sweden were in 2015 the only EU Member States
- which have dedicated public prosecutors for environmental crime.
- Once the e-waste arrives in locations such as Africa or Asia, the hazardous and unsafe
- practices used to recycle the material is a danger for both the health of the workers as well as
- the environment.
- It is not uncommon for child labour to be used in scraping e-waste in such unhealthy
- situations.
- 1_8
- After we have seen a few elements about the urgency and challenges with critical raw materials
- and before we go further on the way to deal with these materials, let's make a pause and ask
- ourselves: do we need all that stuff?
- This question implies that we wonder what our needs are. The problem is that there may be
- numerous answers, and these should come as much from individuals as society as a whole.
- This is also about how relation to technology and consumption habits. Low tech or high tech?
- As a complement to our need for high technologies containing CRMs, there is still room for low
- technologies, often abbreviated low tech. Indeed, in some cases, simple technology, often of a
- traditional or non-mechanical kind, such as crafts and tools that pre-date the Industrial
- Revolution can still be useful. Another interest is that low technology can typically be practiced
- or fabricated with a minimum of capital investment by an individual or small group of
- individuals, which empowers the independence towards manufacturers. Therefore, they often
- have lesser environmental impacts.
- However, the issue of multiple functionalities brought by high technologies needs to be
- weighed. For example, a smartphone not only replace a telephone, but also a camera, music
- player, agenda, and many other things. This means rethinking our needs. Our current approach
- of consumerism is not the only one. We can state several examples: Firstly, Frugality: Frugality is
- the quality of being sparing, prudent or economical in the consumption of consumable
- resources and avoiding waste or extravagance.
- This term implies the concepts of reduction of waste, seeking efficiency, detecting and avoiding
- manipulative advertising and staying well-informed about local circumstances and both market
- and product/service realities. In a sense, it is not far from we will be discussing in the following
- lessons.
- All these principles are general and can be easily applied to products containing CRMs. In
- addition, frugality may contribute to health by leading people to avoid products that are both
- expensive and unhealthy when used to excess. In corporations, frugality has been adopted as a
- strategic imperative by large companies as a means of cost reduction.
- Secondly, Eco leasing is a system in which goods are rented to a customer for a certain period
- of time after which he returns the goods so the company that made it can recycle the materials.
- The operation is similar to regular purchasing of goods, so not requiring a contract to be made
- up as with leasing it is done with appliances and other products used for the household, rather
- than with land or very expensive products.
- The period of time the product is rented would be about the same as the lifespan of the
- product, so it can only be rented once before it is taken back by the company to recover the
- materials and to create another product with it. We will talk more about similar concepts in
- Module 3. Finally, Presumption: This word composed by production and consumption refers to
- the creation of products and services by the same people who will ultimately use them. This is
- what is done in the Do It Yourself (DIY) approach as a means of economic self-sufficiency or
- simply as a way to survive on diminished income. For example, the open source software
- movement creates software on their own; this is the case of the operating system Linux which is
- now used on most servers.
- We also find the Fablab movement relating to self-fabrication capabilities, especially 3d printing,
- and the voluntary simplicity movement that seeks personal, social, and environmental goals
- through prosumer activities. Here are some examples: repairing clothing and appliances rather
- than buying new items or distribution technologies to foster independent, open, non-profit,
- "consumer-to-consumer" media and cultures, see Wikipedia. Sharing the resources, the issue of
- common goods.
- All these different approaches may question our consumption habits, and also our conception
- of property. More precisely, such changes entail to rethink what is the domain of individual
- property and what belongs to common goods. The commons are the cultural and natural
- resources accessible to all members of a society, including natural materials such as air, water,
- and a habitable earth. These resources are held in common, not owned privately. Commons
- can also be understood as natural resources that groups of people, communities, user groups,
- manage for individual and collective benefit. This involves a variety of informal norms and
- values, social practice, employed for a governance mechanism.
