Can a bug fix help food waste?
Food waste from homes, grocery stores, restaurants, and dining services – over 1 billion tons annually – ends up in landfills. Some is composted or used in other ways, but much ends in waste with China, India, and the US generating the most. Once in a landfill, wasted food emits carbon into the atmosphere, especially in the form of methane. Diverting food to feed those in need is one path; when past edible status, composting is another.

From the Eiffel Tower, the view includes cafés, restaurants, bakeries, and boutique grocery stores. A gourmet nation, France banned grocery store food waste, requiring by law in 2016 that stores donate edible food. Norway pledged to reduce food waste by working with groceries to discount or donate before “sell by” dates; Denmark followed suit. Japan, with little space for landfills – the fate of much wasted food – created a national food bank, supported by a new law requiring food recycling, and included lessons on food waste in the national educational system. In the US, California, Connecticut, Massachusetts, New York, Rhode Island, and Vermont developed no-landfill policies, introducing waste management systems and composting services.

But more is needed. Enter the black soldier fly larvae (BSFL). These critters have a hearty appetite and an impressive digestive track that can transform food waste into material for animal feed, prebiotics, cosmetics, and soil-amendment fertilizer, biogas, and even biohydrogen now in development- all from their own waste, termed “frass.” (Interested in that term? “Frass” derives from German “Fressen” meaning to eat with a certain style resembling gusto.)

In the US, several projects tested the little soldier fly as part of the Fertilizer Production and Expansion Program (FPEP). Oregon’s Chapul Farms introduced the approach in their closed-loop agriculture program in partnership with Tainable: Regenerative Agricultural Laboratory. Mississippi State University’s Department of Plant and Soil Sciences assessed the approach, noting that BSFL mate and multiply quickly.

Ethicists raise issues regarding insect farming, an industry worth $1.18 billion in 2023. Mealworms and crickets are commonly raised to be sold directly as food or for producing animal feed; pulverized insect powder is used in breads and protein bars. But BSFL may be different because the insects are not consumed, but rather fed. It is their by-product, frass, that is used; not them. Still, there is production on an industrial scale. What is your view?

Land, sea, or space – where is the best place to mine critical minerals? Image: “Three Globes” by Alex Carmona, 2001. Public Domain, with appreciation.
Land, Sea, or Space – the search for critical minerals has increased in importance, and value, with the advent of renewable energy technologies requiring mineral-dependent battery storage. This week, Ukraine and the United States were about to finalize a deal for access to Ukraine’s critical minerals as spoils of war, with an unclear promise of protection stating “we’ll be looking to future security later on” (Butenko 2025). Ukraine holds about 5% of the planet’s land-based critical minerals including 19 million tonnes of graphite, essential for batteries powering electric vehicles, as well as one-third of all European deposits of lithium, another battery essential. It should be noted that Ukraine’s President Zelensky opened up the topic for discussion several months ago when the US administration appeared to be swinging into a more transactional stance; the deal appears to be in question, following a meeting on 28 February 2025. World Economic Forum reports Ukraine has 20,000 mineral deposit sites with only 15% yet tapped.
There are three places where minerals and metals can be obtained: land, sea, and – now – space. All three have problems, and potential, but some say space mining may be the least destructive.

Land mining for minerals like cobalt or copper, for example, inflicts environmental damage, affects First Nation or Indigenous people on whose land such mining often occurs, and adversely influences public health. In some mining areas, like the Democratic Republic of Congo, human rights violations are a concerning problem.
Seabed mining would cause yet-unknown destruction to the marine environment. Print of sea anemone (Actiniaria) by Giacomo Merculiano, 1893. Pubic Domain, with appreciation.
Seabed mining may pose even greater environmental damage. Mining always involves explosives and massive disruption. It’s bad enough on land, but what will happen when explosions and digging by autonomous robotic bulldozers hack open the deep seabed’s polymetallic nodules to harvest cobalt, nickel, and other critical minerals? How far will ocean current carry and spread debris? And, which victor would own the spoils? The United Nations Convention on the Law of the Sea (UNCLOS) assigns the right to exploit mineral resources only to a set point for coastal nations. Everything beyond 200 nautical miles belongs to everyone: it is the blue commons. Managed by the International Seabed Authority (ISA), seabed mining is advancing: contracts moving from exploration to exploitation are in development. There is cause for concern. So, if land and seabed pose environmental, economic, health, and political problems, what’s left? Look up.
Asteroids contain an abundance of critical minerals: advocates of space mining point out that no environmental damage to (known) habitat would occur. Image: “Comparative sizes of eight asteroids by NASA, JPL-Caltech/JAXA/ESA. 2011. Public Domain with appreciation.
Space mining may offer access to critical minerals without disturbing land, or sea. Asteroids contain an abundance of cobalt, copper, graphite, iron, nickel, platinum, and rare earth elements, among others. Japan’s space agency JAXA recently obtained asteroid samples for analysis. China will launch Tianwen-2 to explore asteroid 2016HO3, and then visit the asteroid belt between Mars and Jupiter. United Arab Emirates plans a similar trip in 2028. NASA in the US scooped material from Bennu and will visit Psyche in 2029 to sample the metals worth $10,000 quadrillion – more than the entire global economy.

While governments have resources for launches and collections (it cost NASA’s OSIRIS-REx, Asteroid Sample Return Mission, $800 million), private enterprise may play a role. Early entrant Planetary Resources failed to launch, as did Deep Space Industries. New companies like US-based TransAstra and China’s Origin Space are developing space mining. But the first place runner may be AstroForge. Founded by Jose Acain and Matt Gialich, the company’s strategy is to launch a patented mini-refinery that can perform mineral extraction while in space, and return to Earth only the valuable material from metallic (M-type) asteroids. Set for launch from NASA’s Kennedy Space Center on a SpaceX Falcon 9, AstroForge’s “Odin” will travel to Asteroid 2022 OB5, about 403,000 miles (649,000 kilometers) from Earth to examine what is expected to be a M-type asteroid rich with platinum.

Which is preferable: mining critical minerals from land, sea, or space? The first two surely have environmental and political problems. The third may cause space debris, a different kind of environmental issue. But, as space policy attorney Paul Stimers observed: “We are removing a rock from something that has no life, no ecology, no indigenous people – none of the downsides of traditional mining.” Legal concerns involve law firms like Stimer’s Holland & Knight or the Duchy of Luxembourg where many space exploration private companies register. Global legal frameworks are spare. The Outer Space Treaty of 1967 mentions only countries, but not private enterprise. The Convention on International Liability for Damage caused by Space Objects, implemented in 1972 , considers space debris. But who owns asteroids? Apparently, anyone who can get there – and back.

Boston’s transport nexus, venerable South Station, has seen many a commuter step across its hallowed floors since opening in 1899. Terminus of public transportation on the Central Artery, South Station lit up when MIT students James Graham and Thaddeus Jusczyk demonstrated a piezoelectric floor with kinetic tiles generating both electricity and data in the transport hub welcoming 75,000 T-riders daily.

During London’s 2012 Olympics, some visitors marveled at London Bridge, and then headed for the Games, accessed via the West Ham Tube Station. There, a piezoelectric floor designed by Laurence Kemball-Cook, then a student at Loughborough University, generated electricity from footfalls of arriving visitors to illuminate the station. Kemball-Cook soon started a company called Pavegen Systems that designs floors for high traffic environments like sports stadiums.

Marie and Pierre Curie used piezoelectricity in their Nobel Prize work. The electric phenomenon had just been discovered by Pierre and brother Jacques. Image: “Marie et Pierre Curie” in 1900 in their Paris lab. Public Domain.
Piezoelectricity (a term coined by Wilhelm Gottlieb Hankel in 1881 from the Greek “to squeeze or press”) refers to release of an electric charge found in materials such as crystals or ceramics. A year before, Jacques and Pierre Curie discovered the effect using cane sugar, Rochelle salt, quartz, topaz, and tourmaline. Marie and Pierre Curie, Nobel Laureates (and the first married couple to win the prize jointly) used piezoelectricity in their work on radium with Henri Becquerel.
What if you could charge your phone by walking? University of Birmingham, UK, installed a kinetic floor that powers students’ phones and computers. Image: “Charging smartphone” by Santeri Viinamāki, 2016. Creative Commons 4.0. Included with appreciation.
Uses for electricity generated by kinetic flooring are varied. UK’s University of Birmingham found students were constantly having to charge their phones. When they installed a floor (designed by Pavegen), the steps students walked generated enough power for phone charging. Pavegen also developed a digital app with “redeem or donate” options for energy currency: users can claim benefits to special events or support causes. Coldplay’s Music of the Spheres World Tour (MOTS: 2022-2025) now travels with a portable dance floor composed of 44 kinetic tiles made from recycled plastic.

Geography is destiny, some observe. Timing accelerates the pace. And now, climate might be changing both. It is Mexico’s time?
Mexico’s Isthmus of Tehuantepec connecting Pacific to Atlantic might complement the Panama Canal, and offer a number of opportunities for transport. Image: “Isthmus of Tehuantepec” by Kbh3rd, 2007. Creative Commons 3.0. Included with appreciation.
Mexico’s Isthmus of Tehuantepec, spanning the Pacific Ocean from Oaxaca to the Atlantic Gulf at Veracruz, has always fascinated visionaries who could see a highway, a railway, or a canal opening a transoceanic route of 188 miles (303 kilometers). Archival records show 16th century sketches of a connection. In 1811, a canal was proposed by Alexander von Humboldt who had traveled to the isthmus from 1799-1804: he also proposed another connective site that is now the Panama Canal. The route chosen by von Humboldt made clear the advantage of geography that can offer connection.

Macro engineering needs the right time and the right leader. The Channel Tunnel, linking England and France, had been envisioned by Napoleon, resisted by General Wolseley, but finally achieved in a design initiated by Frank P. Davidson along with a team of diplomats, engineers, and financiers: it is now the site of Eurotunnel.
Not everyone seeks closer connection. General Wolseley, seen here riding the fleeing lion, opposed the Channel Tunnel. Image: F. Graetz, 1885, from Puck Magazine. Public Domain.
Many tried to optimize the connective advantage of Mexico’s Isthmus of Tehuantepec. Mexico’s President Anastasio Bustamante proposed an 1837 plan for a railway. In 1842, the government (provisional) of Antonio López de Santa Anna granted José de Garay a fifty-year toll collection privilege in return for a survey leading to construction. (A similar provision was granted to Ferdinand de Lesseps who then built the Suez Canal.) When Porfirio Díaz, who hailed from Oaxaca, rose to the Mexican presidency, he inaugurated the first operation of the Railway from the port of Santa Cruz, carrying sugar from Hawaii. Six years of success ensued: 850,000 tons of cargo traversed the isthmus.
Railway won: Mexico launched the first railway in 1850. More would follow. Image: Announcement of Mexico’s first railway, 1850. Public Domain.
But then, in 1914, disruptive new technology happened: the opening of the Panama Canal. Isthmus rail traffic plummeted by one third; the next year, by 77%. Panama was shorter (just 40 miles or 65 kilometers), easier, and more cost effective because cargo loaded on a ship could remain onboard the same vessel that would carry it on to global ports. As many as 32 -37 ships passed through the Panama Canal every day – in just 8 hours. The Panama Canal widened the route; container ships grew in size and capacity.
Panama Canal, NASA image, 2002. Public Domain.
In 2023, a new situation threatened the Panama Canal: climate change. Drought threatens the region. The waterway, widened to accommodate ever-larger ships, may no longer support the heaviest behemoths. Limiting the number of ships per day began in 2023. If drought is severe, ships have to wait offshore for longer (and more expensive) periods; some buy their way up the line. Image below shows ships queuing up to traverse the Canal in 2023.
Enter Mexico. Observing an opportunity, the government began modernization of the Tehuantepec Railway and Oaxacan port of Salina Cruz. New tracks, re-laying of supportive basalt, advanced welding improved the railway. Construction of a breakwater outside the Salina Cruz strengthened the port. A new name was the cap that would announce a global vision: Corredor Multimodal Interoceánico (Interoceanic Multimodal Corridor). The railway is a centerpiece, both historic and futuristic. But much more is planned.
Railway is central but much more is planned. Image: Logo of Ferrocarril Interoceánico, CIIT, 2024. Public Domain.
The project will include a trans-isthmus pipeline connecting the two ports. In response, Salina Cruz will host a liquified natural gas (LNG) plant; that gas will then power ten new industrial parks. Businesses signing on will reap tax breaks for meeting job creation goals. Mexico’s commitment to natural gas expanded the network of pipelines nationally by 50% in the past decade; yet the South and Southeast receive less of that energy. Along with LNG, an existing oil refinery will turn residue into additional petroleum increasing the fossil fuel production by 70,000 barrels. In an area of the world were solar, wave, and wind may offer more environmentally sustainable opportunities, some question the direction of investment. But new partners like Copenhagen Infrastructure Partners will pursue green hydrogen, as well.
Some of the businesses moving to CIIT industrial parks may include those producing green hydrogen. Image: “NGC 604, ionized hydrogen in the Triangulum Galaxy” by Hui Yang, University of Illinois and NASA, 1995. Public Domain.
While a canal is not planned, cargo ships are invited to offload their cargo on the Pacific side, carry the containers across the railway stretch, and then re-load on the Atlantic side, probably to a partner vessel. With drought compromising the Panama Canal, Mexico may attract maritime shipping traffic, perhaps picking up 5% of Panama’s commerce. That would be a small percentage of a big number: in 2023, the Panama Canal’s revenues reached $4, 968 billion.

In all of the activity initiated by the Corridor, as it is known in English, and its potential to offer opportunity to southern Mexico, not everyone is sanguine: the First Nation and indigenous communities have expressed concern. Zapotec leaders won a lawsuit protesting land purchase for one of the planned industrial parks. Land payments also troubled a Zapotec activist who had protested the distribution of the funds: when he was found dead, such violence raised more concern – and fear. Human rights violations began to be raised. Mixe community leaders blocked progress on their section of the Railway: arrested protestors were released in response to demands by the National Indigenous Council. Indigenous concerns include disturbance of agricultural soil health and biodiversity.

This week marks the 79th year since the tragedy of nuclear warfare. Japan, only country to have experienced the effects of nuclear warfare, has always pledged non-participation in nuclear arms development. While the US has traditionally included Japan and South Korea in its protection, recent geopolitics in the area (and elsewhere) may encourage self-protection. With fear rising in Seoul due to its nuclear northern neighbor, 71 per cent of South Koreans surveyed expressed belief that self-protection may be necessary.

Japan may be less inclined. There are still 106,823 survivors who are a testament to the tragedy of August 1945. And the present generation who experienced the 2011 Fukushima disaster have grown wary of nuclear danger: not just in war but in energy production. In the Fukushima tragedy, 47,000 people fled their homes, ocean water near the plant became contaminated, and 80 square miles (207 square kilometers) were declared uninhabitable. Loss and damage remediation cost: estimated at $660 billion (71 trillion Yen). Those who visit Fukushima, or the Hiroshima Peace Memorial Museum, may reflect upon past – and future- nuclear decisions.

Einstein, whose letter to then-president Franklin D. Roosevelt led to the development of the Manhattan Project that resulted in the bombs, said it was his life’s biggest regret. Is it finally time for the world to join and support Hiroshima’s declaration, this week, that we must move from “ideal” to real action in nuclear disarmament. Governor Hidehiko Yuzaki of Hiroshima Prefecture noted that once a weapon is invented, likelihood of use becomes a problem that may never resolve. If you want to support nuclear disarmament, lift your voice here or here.
Wyoming is the location of TerraPower’s civil nuclear energy and electricity plant with a new, safer design: will it change nuclear decisions? Image: “John Moulton Barn at base of Grand Tetons, Wyoming” by photographer John Sullivan, 2004. Dedicated to the public domain.
But what about nuclear power as a non-carbon source of energy in a world seeking to stop carbon-caused climate change? Microsoft co-founder and philanthropist Bill Gates invested in TerraPower in 2008: in 2024, the company developed a new design for a power plant in Kemmerer, Wyoming, USA. Gates noted that former nuclear designs use water to cool the system (a problem in the Fukushima disaster), but the Wyoming project will use liquid sodium. The medium can withstand eight times more heat than water, and does not require pumping back into the system. It still uses uranium, however.

Uranium is radioactive in all its isotopes; U-235 is fissile, and is the basis for most of the world’s nuclear power stations. As a mineral, uranium decays into other, lighter, elements: but it takes time. The half-life of U-235: 704 million years. Storage of spent fuel continues to be an issue. The world’s biggest deposits of uranium are in Australia, Canada, and Kazakhstan: these countries therefore may influence world nuclear policies.
Not all countries have signed, and ratified, the Comprehensive Nuclear-Test-Ban Treaty (CTBT). How can you help to advance support? Image: “CTBT Participation as of 2022” by graphic designer Allstar86. Creative Commons 3.0.
Even more influence comes from those who have not signed, or have resigned from, the global Comprehensive Nuclear Test Ban Treaty (CTBT). Russia pulled out; the US has signed but never ratified. India, North Korea, and Pakistan have not yet signed. While 187 nations have agreed, only 36 have ratified. In addition to the US, China, Egypt, Iran, and Israel have not yet ratified. If you live in a country that has not signed or ratified, your action and encouragement can make a difference.
France has the largest share of civil nuclear power for electricity generation. It is also home to ITER, site of development of fusion energy. Image: “Nuclear plants map of France,” by graphic designer Sting, 2006. Public Domain.
But as the Atomic Energy Act reminds us, nuclear power is an energy form with environmental (and medical) benefits. Advocates of nuclear power, including Gates, speak of its potential to help the world achieve a carbon-free, net-zero goal as we transition away from coal, gas, and oil. Many join Gates in supporting nuclear energy for a carbon-free world. Today, there are nuclear power plants supplying energy and electricity in over 50 countries. The US, France, China, Japan, Russia, South Korea, Canada, and Ukraine (in that order) are the top producers; France has the largest share of energy generation from nuclear. Germany, however, decided to phase out and decommission its nuclear energy infrastructure.
Global Zero is an international organization dedicated to a world without nuclear weapons. Image: “Global Zero” by Global Zero. Public Domain. Included with appreciation.
But even if new civil nuclear designs like that of TerraPower are safer operationally, are nuclear power plants still a danger as potential targets? Ukraine would say this is sadly true, as evidenced by recent threats to Zaporizhzhia. Bombing or otherwise exploding a civil nuclear facility built to generate electricity would result in two disasters: disabling energy infrastructure and triggering a radioactive explosion that would cause immediate casualties and lingering contamination. A database of nuclear terrorism is maintained by the Monterey Institute of International Studies, James Martin Center for Nonproliferation Studies Middlebury Institute of International Studies at Monterey, and the Center for International Security and Cooperation at Stanford University. Organizations like Global Zero offer ways to get involved. The United Nations Treaty on the Prohibition of Nuclear Weapons, 7 July 2017, offers a vision.
In the next part, we’ll look at possibly safer forms of civil nuclear energy. Using uranium may be dangerous, but could small modular nuclear reactors (SMR) be less of a threat? And will the work of Jean-Louis Bobin and other physicists developing nuclear fusion independent of uranium change the field – and the world?
When learning that this week marks the 79th anniversary of the use of nuclear weapons in war, a student remarked: “By next year, the 80th, how can we reach complete nuclear disarmament?”

It is more than ironic to mine the deep seabed to stop climate change. It could be irreparably tragic. But there is still time.
World Bank and International Energy Agency estimate a 500% increase in demand for battery metals and minerals like cobalt by 2050. Now, cobalt is mined on land, with some concerns about environmental damage. Is deep seabed better? Do we really need to deploy explosives and bulldozers to blast open seamounts and crusts for cobalt, manganese, nickel, titanium? Not only will such invasive actions damage the direct area, but ocean currents certainly will carry the effects further.
Clarion-Clipperton Zone, between Hawaii and Mexico, contains more minerals than all the land-based supply. But should we mine the deep seabed? Image: “Clarion-Clipperton Zone” by NOAA, 2011. Public Domain.
The deep seabed’s seamounts and crusts – the same environments where minerals are formed – are habitats of corals, crabs, fish, sea stars, and marine seagrasses of more than 70 species. Recently, the UK’s National Oceanography Centre’s Seabed Mining and Resilience To Experimental Impact (SMARTEX) explored the Clarion-Clipperton Zone (CCZ) between Hawaii and Mexico, finding new lifeforms including a sponge with the longest-known lifespan on Earth – 15,000 years. The CCZ is home to vast marine life, including 5,578 species – 88% of which are newly discovered and not even named. The CCZ’s polymetallic nodules contain more key metals than the entire world’s land-based reserves, making it prime prospecting territory. But is it necessary? Do we really need deep seabed mining for minerals like cobalt?

Cobalt is recyclable and reusable. So is nickel. Companies and governments that use such minerals find it easier to obtain “virgin” mineral resources than to engage in recycling. European Commission currently proposes negating Directive 2006/66/EC and upgrading Regulation (EU) No 2019/1020 to require more recycling. Cobalt and copper are largely recycled but most minerals and metals have recycling rates under 34%; some just 1%.
Should the International Seabed Authority (ISA) call for a moratorium on exploitation mining? Now is the time to express your opinion. “ISA Logo” Public Domain.
The International Seabed Authority (ISA) issues and approves contracts for exploration of the deep seabed beyond national territories. ISA has the power to grant exploitation – mining. Recent actions by member nation Nauru triggered an acceleration that may lead to exploitation contracts as soon as this summer. Right now, ISA’s future leadership is about to be decided in a coming election. It is a critical time. The marine environment needs your support now.

Steam is needed to brew beer. Image” “THAT is what I like,” by photographer Alan Levine, 2012. Creative Commons 2.0. Included with appreciation.
Today is the solstice. It’s summer – in some parts of the world – perfect weather for enjoying a cold drink on a hot day. Chances are that beverage, and its glass, were brought to you by steam. Brewing craft beer, sterilizing dental or medical instruments, cooking, heating – all these activities require steam. Fossil fuels power 73% of energy in the United States: 40% is used to make steam. Usually produced by boilers, powered by coal, gas, or oil, the industry standard could soon change.
Beer brewing may be the same, but steam is changing. Image: “Beer at the bottom of a glass” by photographer Specious, 2009. Creative Commons. Included with appreciation.
Transitioning to a new energy source often requires installing new, expensive infrastructure – think electric vehicles and charging stations. But if the same infrastructure could be used, phasing out and phasing in could be seamless. That is the case with emerging technology of green steam, A similar advantage can be found in biofuels for aviation: sustainable aviation fuels can be pumped into jet aircraft now using fossil-based kerosene. Saving costs of building new infrastructure, saving costs of removing old systems, saving jobs by keeping the same personnel, and saving energy – it is a win worth getting steamed up about.
Aeolipile – from Knight’s American Mechanical Dictionary, 1876. Image: Public Domain.
The first steam engine, called the aeolipile was described by Vitruvius who also wrote about the Roman Aqueducts. In 1712, Thomas Newcomen, said by some to be the progenitor of the Industrial Revolution, invented an atmospheric engine powered by steam – it pumped water out of coal mines, thus advancing the use of coal for energy. Since Newcomen, steam has been made by burning coal, or other fossil carbon-based fuels.

Enter Spirax Sarco. The UK-based powerhouse is testing a zero-carbon boiler for a food manufacturer. The food and beverage industry produces 11% of the world’s greenhouse gases – same as the total emissions for Belgium. The food and beverage industry contributes $412 billion to the U.S. economy. In the EU, the industry employs 4 million people. Developing zero carbon steam technologies for this industry will help to meet global climate goals.
Steam is a natural phenomenon. Image: “Grand Prismatic Spring with steam rising from Excelsior Geyser.” by Frank Kovalcheck, 2008. Creative Commons 2.0. Included with appreciation.
Steam didn’t need to be invented. It has been a product of the Earth longer than humans have been on the planet. Visit Iceland and you’ll see steam rising from the geysers. Steam uses water: in a drought-threatened world, more efficient steam can save water and reuse this critical resource. Beer brewing is one example of using water and steam, with a few other ingredients. The beverage is so traditional it is made by the monks of the Abbey of Our Lady of Saint-Remy, Belgium, a Cistercian Order of Strict Observance. You can’t enter the monastery, but you can toast with their beer, made by traditional processes.

Enter AtmosZero. The US-based start-up company that just received Series A funding by Engine Ventures along with backing by Constellation Energy Corporation, Energy Impact Partners, Starlight Ventures, and AENU, is developing a boiler driven by heat pump technology. The U.S. Department of Energy awarded AtmosZero a $3 million grant for Industrial Efficiency and Decarbonization. The innovative Boiler 2.0 is a “drop-in” system that can replace carbon fossil-fueled equipment. The system generates two times more heat than its energy input. An early adopter and beta-tester: New Belgium Brewing, a craft beer company in Colorado. Cheers!

Nickel is critical to the renewable energy revolution. Image: “Section of pure nickel accretion,” by Images of Elements, 2009. Creative Commons 3.0. Included with appreciation.
It’s driving the electric vehicle and renewable energy revolution, but nickel has vexed miners and chemists since the earliest days. In fact, nickel got its name because of its difficult nature. Nickel – from German “Kupfernickel” or “Old Nick’s Copper.” Miners who discovered nickel thought it was copper but were never able to extract copper from it. They named it after their term for the devil: “Old Nick.” In a side note, nickel’s etymology also gives us a favorite bread: “Pumpernickel,” perhaps because the devil enjoyed this dark loaf.

.Nickel is valuable for its ferromagnetic properties: it is one of four with such powers. The others are cobalt, gadolinium, and iron. Over 60% of world nickel production makes its way to becoming stainless steel.

When such steel is no longer serviceable, it can be scrapped and recycled, turning the nickel back into use for more stainless steel, or – increasingly – batteries including nickel-cadmium or NiCad batteries.

Presently, only 4% of the world’s nickel is used in rechargeable batteries, but with electric vehicles that market is growing, accelerating demand. Another developing use for nickel – wind turbine blades, where nickel is used as a superalloy.

Nickel was at one time so abundant that in 1881, a coin in Swiss currency was made from pure nickel. In the United States, the coin called the “nickel” was introduced in 1857, but it was made with nickel alloyed with copper.

Despite its name as an American coin (the origin of the term is actually German), there is not much nickel found in the United States, although there is a mine in Riddle, Oregon that produced 15,000 tons (in 1996). That same year, Russian nickel mines yielded 230,000 tons, followed by Canada (183,000 tons), Australia (113,000 tons), and Indonesia (90,000 tons).Trading as a commodity, nickel’s pricing per ton ranged from 15,614 to 25, 076 in 2024. Metals like nickel are traded on the London Metal Exchange (LME).

Like cobalt, nickel can be found in the deep seabed. In fact, exchange prices – like those on the London Metal Exchange – for nickel and cobalt, are influenced by estimates of deposits located in the seabed. In particular, cobalt and nickel are inter-related, often found together. On land, their mining is known, although not often enough followed by recycling and re-use. Under leagues of water, the process is not tested, and is also contested.
Nickel and cobalt are both targeted for deep seabed mining: contracts are soon to be defined. You can vote your opinion here. Image: “Deep seabed mining schematic” by G. Mannearts. Creative Commons 4.0. Included with appreciation.
Another place nickel may be found is in the sky. Asteroids, especially those categorized as M-type or M-class, contain iron and nickel. But the search will be long: only 8% of asteroids, like Lutetia (see in image below) are M-type.

Cobalt, nickel, and other minerals and metals that are critical for use in renewable energy are recyclable and reusable. Yet, the International Seabed Authority is reviewing contracts for nickel mining. Asteroid mining companies are also in the race. But nickel recycling may be a better bet and more certain investment. Nickel recycling has been expensive and difficult, requiring high heat and releasing toxic fumes. In former times, it may have seemed easier to obtain primary nickel (mined) than to pay for secondary nickel (recycled). Tax credits and rebates could help.

But innovation-leading companies including Aqua Metals in Reno, Nevada, USA, and ABTC, as well as the Nevada Center for Applied Research (NCAR) at the University of Nevada, Reno and Greentown Labs, may change the way we use – and reuse – nickel. Presently 68% of all nickel already mined is recycled, but 17% is still dumped in landfills. Will the recent Declaration of Metals Industry Recycling Principles help to make mineral and metal recycling the industry standard?

While fossil fuels are used up when combusted (leaving greenhouse gases), minerals and metals are not depleted because they only conduct and store energy. Minerals and metals can be recycled and reused. Have a nickel in your pocket? Be the change.
Cobalt is essential for supporting renewable energy. Land-based cobalt mining is difficult, and sea-based is dangerous. Cobalt is 100% recyclable and reusable. How can we maximize minerals? Image: “Cobalt Mineral” by Bhavss1214. Creative Commons 4.0 Included with appreciation.
International Energy Agency predicts 500% increase in demand for minerals like cobalt by 2050. Cobalt is generally associated with mining, and more than half of land-based global cobalt reserves are in the Democratic Republic of Congo (DRC). The Kamoto mine in Katanga and the Metalkol RTE run by Eurasian Resources Group (ERG) are noteworthy; ERG joined the Responsible Minerals Assurance Process as part of the Responsible Minerals Initiative that prohibits certain labor practices in the DRC mining industry. But do we need a Responsible Minerals Initiative for the sea?

Land-based mining is running out of minerals like cobalt. So, attention is now turning to the deep seabed, especially the mineral-rich Clarion-Clipperton Zone (CCZ). To get an idea of the size of the CCZ, it is as wide as the continental United States, and stretches across the Pacific from Mexico to Hawaii. Here may be found polymetallic nodules containing manganese, sulfide deposits, and ferromanganese crusts with cobalt, manganese, nickel, titanium – even gold. The gold alone is worth $150 trillion. Polymetallic nodules in the deep seabed contain more key metals than the entire world’s land-based reserves.

Some mineral deposits lie within national exclusive economic zones (EEZ) of coastal countries who have rights to their waters (and seabed minerals) within 200 nautical miles/230 land miles (370 km). Everything beyond belongs to everyone, even landlocked countries. This is the blue commons. It is related to the diplomatic peace principle of the Suez Canal – “open to all nations in times of war and peace.” The principle was first defined by Hugo Grotius (1583-1645) in the Latin phrase mare liberum (sea + free).

The deep seabed is governed by the International Seabed Authority (ISA), a United Nations agency authorized as part of the Law of the Sea. Any signatory nation of the Law of the Sea may apply for a contract authorizing exploration of the seabed. After a number of exploration years, that country may apply to move towards exploitation – mining. Private partners are allowed, so some very small countries like Nauru have thus exercised their rights with some very big partners like The Metals Company.

But there is more in the deep sea than minerals. Research ship James Cook just completed a study of marine species in the Clarion-Clipperton Zone. As many as 5,000 never-yet-named species may be living in the CCZ. Some of species thrive in symbiotic exchange with polymetallic nodules. It takes millions of years to build a polymetallic nodule of just 8 inches (20 centimeters). Imagine the disruption and environmental damage if an autonomous robotic bulldozer were to rake up the nodules. And, while mineral mining on land can result in accidents and environmental damage, imagine what that would look like undersea – using explosives and heavy machinery. Will the UN Convention on Biological Diversity protect the CCZ?

Some believe mining deep seabed minerals is the only way we can get to a fully renewable energy future; other science and technology experts state we can optimize present use of metals and minerals by more than 50%, and not need to invade the seabed. And, it is critical to note that the minerals like cobalt, lithium, and nickel – essential for renewable energy conductivity and storage – are recyclable and reusable.

ISA is nearing approval of deep seabed mining contracts for exploitation. Environmental advocates like Sir David Attenborough, Dr. Sylvia Earle, and Lewis Pugh have joined hundreds of scientists who recommend a moratorium on decisions to advance deep seabed mining. The UK-based James Cook voyage is part of the Seabed Mining and Resilience to Experimental Impact (SMARTEX). If you would like to convey your opinions and recommendations, you may contact the ISA here. Other options are to communicate with SMARTEX here.
