OM in the News: Can AI Rescue Recycling?

Recyclers across the U.S. are struggling, hurt by a shortage of workers and rising costs that too often make recycling uneconomic. They are hoping, writes The Wall Street Journal (Nov. 9, 2023), that artificial intelligence can help turn things around and boost recycling rates.

How can AI help? By doing the sorting work that a dwindling number of people want to do—and doing it better. AI-driven robots pick up recyclable trash at around 80 pieces a minute; people can sort 50-80 pieces a minute. Optical sorters, a more established technology that’s growing more efficient thanks to improved AI, are much faster, sorting up to 1,000 pieces a minute.

Staffing shortages mean sorting sites can’t operate at full capacity. (Sites are often only 80% staffed and sometimes as little as 20%). In the long run, sorting machines are cheaper than human labor. Recyclers typically recoup their investment in robotic systems in two years. Around 32% of the sorting centers in the U.S. are now using robotics, up from less than 5% in 2019.

Optical sorting machines are in most of the large facilities. They use sensors and lights to rapidly find what is recyclable on a conveyor belt of mixed materials. When recyclable materials are identified, the machines fire a burst of compressed air at them to sort them into bins.

Waste Management, the biggest recycler in the U.S., is betting on AI as part of its goal to boost its recovery of recyclable materials 60% by 2030. It is investing $1 billion in recycling infrastructure including 40 recycling centers through 2026, with a big portion going to automation and AI. An automated WM plant has 4-6 people sorting along with the machines, compared with 50 employees at a nonautomated facility.

Republic Services, the second-biggest waste-and-recycling company, is investing in robots as part of its goal to recycle 40% more key materials by 2030, including cardboard, metal, paper and plastics. The company plans to have robotics at 20% of its 74 sorting centers in 2024, up from 10% today.

Still, AI brings its own challenges. Robots require upfront spending and equipment that needs frequent maintenance and upgrades. The cost for a single robot ranges from $150,000 to $300,000. Building or upgrading a recycling center around optical sorters is even more expensive than robots. Optical sorting systems cost $1-2 million each.

Recycling of municipal solid wastes has actually dropped in recent years. Why?
What are the advantages and disadvantages of AI in this field?

OM in the News: The Transition to Electric Vehicles Sustainability Dilemma

A mining exploration camp in the *Ring of Fire*

The pace of the global transition to electric vehicles depends on the future of a remote region in Canada known as the Ring of Fire. Located underneath a distant, swampy expanse in Northern Ontario that is cut off from major roads, the Ring of Fire is seen as one of the world’s most important untapped sources of nickel, copper and cobalt—metals essential for making the batteries that power EVs.

But the precious commodities are buried under a vast ecosystem of peat bogs that hold more carbon per square foot than even the Amazon rainforest. Digging them up could trigger the release of more greenhouse gas than Canada emits in one year, turning one of the earth’s biggest carbon sinks into a major source of emissions.

A debate over how, or whether, to tap in to this mother lode, has touched off a fight between mining companies, climate advocates, and indigenous groups as demand for cleaner energy and EVs has surged worldwide, reports The Wall Street Journal (Sept. 29, 2023).

“If I have to hop on a bulldozer myself, we’re going to start building roads to the Ring of Fire,” said the head of Ontario province, which recently signed deals with automakers VW and Stellantis to build battery-making factories in the province. Opponents warn that disturbing the area could have far-reaching consequences.

The Ring of Fire, an area larger than Rhode Island, was formed 3 billion years ago. A retreating ice sheet left sodden, boggy terrain that covers a wealth of minerals. This deposit is “the most valuable nickel deposit, undeveloped, in the world,” said one mining CEO. “We’re not going to be able to switch off fossil fuels, which are destroying the planet, unless we have abundant supplies of nickel.” He estimates the deposits of platinum, palladium, copper and chromite could be worth $67 billion. As EV production has increased, demand has surged for such metals, which are key components in making EVs and military equipment.

Projects like the Ring of Fire represent a new era for the mining industry. Long considered a dirty and often unfortunate legacy of the industrial economy, mining has taken on a green sheen. Extraction is an essential component of the global movement toward electrification.

Guest Post: Pollution as an Operations Management Issue

Prof. Howard Weiss raises an interesting issue that is in the forefront of many student’s minds.

Recently,
 Shell was sued for air pollution from its plastic plant outside of Pittsburgh
 The German government is being sued for allowing high levels of air pollution
 Monsanto paid $100M dollars to settle a pollution suit for contaminating streams and lakes in Pennsylvania.
Your Heizer/Render/Munson textbook has a graphic (Figure 1.5) on transforming Inputs to Outputs– but perhaps one more output should be added – pollution.

Pollution is an ever-growing global concern that adversely affects the environment and human health. Reducing pollution should be part of the feedback loop. Here are 8 different types of pollution:
1. Air Pollution is one of the most widespread and harmful forms of pollution. Sources include industrial processes, vehicular emissions, agricultural activities, and natural events like wildfires and volcanic eruptions.
2. Water Pollution occurs when contaminants enter water bodies, such as rivers, lakes, oceans, and groundwater. It can stem from various sources, including industrial discharges, agricultural runoff, improper waste disposal, and sewage.
3. Soil or Land Pollution involves the contamination of the Earth’s soil with hazardous substances. This can result from improper disposal of industrial waste, agricultural chemicals, and improper landfill practices. Soil pollution negatively impacts plant and animal life.
4. Noise Pollution is the excessive or disruptive noise that interferes with normal activities, causing stress and potential health issues (and is a topic in Chapter 10). It often originates from transportation, industrial processes, urban development, and recreational activities.
5. Thermal Pollution occurs when there is a significant alteration of water temperature in natural bodies like rivers or lakes. It commonly results from the discharge of heated water from industrial processes, power plants, or nuclear facilities.
6. Light Pollution involves excessive or misdirected artificial light, which interferes with the natural darkness of the night sky.
7. Plastic Pollution is caused by the improper disposal and accumulation of plastic waste. Plastics persist in the environment for extended periods, harming wildlife and marine ecosystems.
8. Radioactive Pollution involves the presence of radioactive substances in the environment, often from nuclear power plants, nuclear accidents, or improper disposal of radioactive waste.

Addressing and mitigating these various types of pollution is crucial for safeguarding the environment and public health. Implementing sustainable practices, adopting cleaner technologies, and enforcing regulatory measures ( all topics of Supplement 5) are essential steps toward a cleaner, healthier planet.

Classroom discussion questions:

How can operations managers address each of these concerns?
Clearly industrial processes create many different types of pollution. What types of pollution do service organizations create?

Guest Post: Kraft Heinz’s Mission to Reduce, Recycle and Replace its Plastics Packaging

Dr. Misty Blessley is Associate Professor of Supply Chain Management at Temple U.

Kraft Heinz, the fifth largest food and beverage company in the world (founded in 2015 with the merger of Kraft Foods and H.J. Heinz companies), is on a mission to reduce, recycle and replace virgin plastics in their packaging, including their tomato ketchup bottles. In 1983, as did many firms at that time, Heinz introduced plastic bottles as the packaging of choice for its famous tomato ketchup distributed to the retail grocery channel.

Virgin plastic is newly produced plastic, and Heinz has a goal of eliminating 100 million pounds by 2030. This is a reduction of 20% when compared to their 2021 baseline. Kraft Heinz recently stated: “When deciding what packages to focus on, we first see if there’s an opportunity to remove any unneeded plastic, then we look for opportunities where we can reduce plastic weight, add recycled content, or replace plastics with other types of materials, while ensuring we do not compromise the product quality and [do] meet consumer expectations.”

Kraft Heinz was able to reduce plastic by simply removing the bag from some products and worked towards their recycling objective by swapping some virgin plastic with recyclable plastic. They are also replacing their plastic ketchup bottles with a paper-based bottle made of 100% sustainably sourced wood pulp. A prototype is currently being tested, for this first of its kind in the sauce category.

Rethinking the Ketchup bottle, Heinz teams with Pulpex to deliver paper-based packaging

The firm is partnering with Pulpex, a packaging technology company focused on delivering sustainability through renewable packaging. If the bottle in the photo looks new yet familiar, it is because Pulpex is innovating with Heinz’s iconic ketchup bottle, the same one seen on Heinz ketchup (at restaurants, as an image on foil packs and dip and squeeze packs, etc.) since 1876.

Classroom discussion questions:
1. Product decisions are fundamental to firm strategy and to competitive advantage (see pages 161 – 162 of your Heizer/Render/Munson OM text). Given the need for sustainability in operations and supply chain management, why and how has packaging become part of the product decision?
2. Why do you think Kraft Heinz and Pulpex both feel that familiar looking packaging is a customer expectation?

OM in the News: The U.S. Enters the Lithium Supply Chain

These days, companies in the south aren’t looking to find more oil—they are instead prospecting for lithium, a metal that is increasingly prized around the world as an essential ingredient in electric-vehicle batteries. “If the U.S. is to ease its dependence for lithium on other countries such as China, it may need Arkansas to lead the way,” writes The Wall Street Journal (July 21, 2023).

The lithium geologic band running through the South

Exxon Mobil, a new player in the hunt for U.S. lithium, is planning to build one of the world’s largest lithium processing facilities in southern Arkansas, with a capacity to produce 75,000 to 100,000 metric tons of lithium a year. At that scale, it would equate to about 15% of all finished lithium produced globally. The prospect could have the equivalent of 4 million tons of lithium carbonate equivalent, enough to power 50 million EVs.

To push the project forward, Exxon and two of its announced competitors will have to profitably scale up the technology used to siphon lithium from brine, which has been an elusive goal across the industry. This particular geologic region, called the Smackover Formation, runs from Texas to Florida. It is rich with saltwater brine, which once bedeviled companies drilling for oil. That brine also contains small amounts of lithium, and the companies are now optimistic they can scale up technologies to extract it. Drilling for lithium with this extraction method is cleaner than traditional mining, and faces fewer regulatory risks.

The mining is expensive, though, costing about $1.5 billion to build 25,000 metric tons of capacity. The three proposed projects would create 6,000 jobs– and require 1,600 trucks by 2028.

Exxon believes it can leverage its engineering prowess to become a low-cost domestic supplier of lithium, and has had discussions with battery and EV manufacturers. The company would also benefit from U.S. green-energy subsidies, which allows for tax credits of 10% of the cost of producing lithium. The firm, generally bullish about the future of oil and natural gas, is also preparing for a future less dependent on gasoline. Last year, Exxon projected demand for auto internal combustion engine fuels could peak by 2025, while EVs, hybrids and vehicles powered by fuel cells could grow to more than 50% of new car sales by 2050.

Classroom discussion questions:

Why is lithium an important EV supply chain component?
What is Exxon’s strategy?

OM in the News: Cutting the Environmental Footprint of Fast-Fashion

“Fast fashion is a problem,” said a European Union official in The Financial Times (July 5, 2023). Lawmakers in the European parliament have called for an “end to fast fashion” and the setting of specific targets for textile waste collection, prevention and recycling. Fast-fashion brands such as the online retailers Shein and Boohoo and clothing giants H&M and Inditex (which owns Zara), have come under increasing pressure to move away from low-cost business models that have resulted in millions of tons of clothes being trashed.

Clothing companies are being pushed to improve the recyclability of their products

The EU wants the textile industry to pay for the processing of discarded clothing and footwear under new rules aimed at cutting the environmental footprint of fast-fashion brands. It proposes to push clothing companies to improve the recyclability of their products and catalyze a growing second market. The equivalent of over 26 pounds of clothes and footwear per EU citizen is discarded each year of which more than three-quarters is incinerated or goes to landfill.

Companies that sell to consumers in the EU would be responsible for paying for the treatment of any waste textiles with the amount charged dependent on the amount of processing required. The cost of making companies pay for clothing waste would amount to 12 cents per T-shirt but it would vary according to the product and what treatment was needed.

Companies say they want to sell more sustainable products, but are hampered by the lack of recycling infrastructure. H&M said it backed the measures and aimed for 30% of its clothes to be made from recycled fibers by 2025. Euratex, the EU textile industry body, said that it was working on pilot projects with small fabric manufacturers in 11 textile producing regions to create a closed loop system with clothes better designed for recycling.

Fast fashion was invented by companies such as Zara, in the late 1990s, when they took the latest styles seen on the catwalk and brought similar products to market. Zara took only 3-4 weeks to bring a simple T-shirt from design to the stores and 6-8 weeks for a jacket or a dress.

Classroom discussion questions:

How do your students feel about fast-fashion its environmental impact?
What is the role of OM in this issue?

OM in the News: The EV Battery Dilemma

Traffic backs up at the Bay Bridge. California is set to implement a plan to prohibit the sale of new gasoline-powered cars by 2035.

Recent U.S. regulations are pumping billions into battery manufacturing and incentives for EV purchases. The E.U., and several U.S. states, have passed bans on gas-powered vehicles starting in 2035. This transition will require lots and lots of batteries, reports Grand View Research (June, 2023).

When a lithium-ion battery, which consists of thousands of cells filled with cobalt, nickel and manganese, comes to the end of its life, its green benefits fade. If it ends up in a landfill, its cells can set afire or leach dangerous chemicals that can contaminate water supplies and ecosystems. The thin metal exterior of a battery will decompose within 100 years, exposing the toxic heavy metals inside, which will never decompose.

But recycling these batteries can be hazardous. If they are not opened carefully, they can explode, short-circuit, and let off toxic fumes. In the coming decades, tens of millions of EV batteries will reach their end-of-life. (Some predict there will be 150 million EVs on the road by 2030. Last year there were fewer than 12 million). Current EV batteries “are really not designed to be recycled,” says one industry expert.

The E.U. and China are setting new rules for some level of battery reuse. But it will not be easy to meet the new regulations. Most recycling processes produce heavy waste and emit greenhouse gases, and very little recycling goes on today. (Recycling rates in the E.U. and the U.S. are less than 5%). Most of the batteries that do get recycled undergo a high-temperature melting-and-extraction process. Those operations, which are carried out in large commercial facilities are energy intensive. The plants are also costly to build and operate, and require sophisticated equipment to treat harmful emissions generated by the process. And despite the high costs, these plants don’t recover all valuable battery materials.

Battery-swapping is one innovative business strategy proposed in OR/MS Today (June 20, 2023). A battery swapping infrastructure station network could provide a service for EV owners to “refuel” their vehicles. Replaced batteries would subsequently be recharged and exchanged for other arriving EVs needing a battery swap. One significant challenge impeding this concept was the need for a universal battery standard that multiple automakers could share. The battery packs needed to have identical dimensions and shapes to be compatible. Tesla tried the concept in 2013, but gave up on it a few years later.

Classroom discussion questions:

Why is battery swapping so difficult?
Why is recycling EV batteries so complex?

Guest Post: Walmart Makes Strides in Reducing Scope 3 Value Chain Emissions

Dr. Misty Blessley is Associate Professor of Supply Chain Management and Academic Director of Experiential Learning at Temple University

Walmart is the world’s largest retailer, with an historically strong brick and mortar presence. According to a recent article in Supply Chain Dive (June 2, 2023), “E-commerce is a growing channel for Walmart, and associated waste and packaging are some of the company’s priority areas as it tackles emissions — particularly Scope 3, or value chain, emissions.”

But what exactly are Scope 3 emissions, how is Walmart tackling emissions in this category, and why it is important to do so?

According to the World Resources Institute’s Greenhouse Gas Protocol, Scope 3 emissions are those that occur in the upstream and downstream value chain.(Scope 1 emissions are tied to a firm’s facilities and Scope 2 emissions relate to purchased energy). What makes Scope 3 emissions so important to address is that this category is about ten times the magnitude of Scopes 1 and 2, according to Walmart’s Chief Sustainability Officer.

Walmart is tackling Scope 3 emissions in its e-commerce by replacing all plastic mailers with paper mailers. This one change will eliminate the need for 2,000 tons of difficult to recycle plastic over the next seven months. A change such as this has huge longer-term implications. Additionally, Walmart has invested in technology in about half of its fulfillment network that helps create custom-fitted packaging. This change is estimated to eliminate the need for packing filler by 60%. Following through to the customer’s hands, upon placing an order they have the option to opt out of receiving their pick-up orders in single-use plastic bags, which is expected to keep millions of bags out of circulation.

Walmart has pilots for reusable or refillable packaging in some categories. They “have a goal for all global private brand packaging to be recyclable, reusable or industrially compostable by 2025,” and they are making strides. In viewing themselves as one node in a larger supply chain, Walmart also encourages their suppliers to consider their alternatives for reducing packaging waste.

Classroom discussion questions:

In what ways is Walmart practicing good corporate social responsibility?
How has Walmart looked beyond design and production for sustainability, to include product distribution?

OM in the News: A Green Mining Mirage

The history of the mining industry is littered with environmental destruction, pollution and detrimental impacts on local populations. But the raw materials it provides—including nickel, cobalt and lithium—are crucial to the transition for electric vehicles. The global race to secure a supply of these critical materials is on, but can it be done sustainably?

A nickel mining site in Sorowako, Indonesia

The big global miners’ stark message: Recycling is the only green source because most deposits contain such low concentrations of metals and minerals that, while methods can be improved to minimize damage, recovering the materials will always be messy and destructive. Most miners have been making efforts to clean up their practices. Some are even investing in recycling, but these aren’t likely to produce a meaningful supply any time soon.

Eventually, the collection infrastructure, recovery processes and recycling facilities may be developed and scaled up to the task, reports Wall Street Journal Pro ( May 11, 2023). There are plenty of old electronic devices cluttering up our drawers that could yield some metals, but it will take at least a decade or two for electric-vehicle batteries to be exhausted and become a sizable feedstock for recycling. Until then, we have mining.

Indonesia supplies about half the world’s nickel, a crucial input for EV batteries. Ford and VW are investing billions of dollars into the local supply chain as a low-cost source that they can directly control. But there are serious questions about destruction of the country’s rainforests in pursuit of the metal. Russia also mines nickel, but westerners are wary of buying from the country after its forces invaded Ukraine. New Caledonia—a French island group in the Pacific—is another possible source, but there are concerns about environmental impact there too.

Another option is to mine nickel from the seabed. It is less destructive than Indonesian sources, but environmental groups worry about damage to the relatively untouched deep sea ecosystem. A major problem is—ironically—that heightened scrutiny of new projects on environmental and social grounds is significantly raising the costs of the new mines necessary to fuel a low-carbon global economy.

Until there are significant developments in recycling, battery technologies, or both, there are tough trade-offs to be made in the transition to EVs.

Classroom discussion questions:

Why is there a shortage of mines to produce the minerals needed in EV batteries?
What are the ethical issues involved in the transition to EVs?

OM in the News: Retailers Tackle Cardboard Overload

The days of tiny online orders shipping to customers in oversized boxes are a step closer to becoming a thing of the past, writes The Wall Street Journal (April 4, 2023).

Big retailers are rolling out machines in their e-commerce distribution operations that make packages sized specifically to fit the items being shipped, potentially reining in some of the big volumes of cardboard generated as online shopping has grown.

Walmart is using machines from packaging-technology company Packsize that take dimensions needed to ship an item, then cut, crease and glue corrugated cardboard to make custom boxes. The machines then label and seal the packages.

Walmart said it has installed machines that churn out custom boxes at 12 of its fulfillment centers, and plans to add the technology to more. It has been able to cut down the amount of cardboard and filler material it uses per order by making individual boxes.

Amazon has also been increasing its use of made-to-fit packaging to ship items from books to shoes. It started using custom packaging in 2016 and is expanding its use of the technology.

Retailers traditionally have used boxes of set sizes to fill online orders, many of them not suited to the enormous array of products now available online. The push to deliver goods faster has also put a premium on speed in fulfillment centers, leading workers to stuff goods in the closest available boxes. But the speed and functionality of machines that make custom boxes has improved in recent years.

The accumulation of cardboard in households, trash heaps and recycling centers has been one visible result of the surge in online shopping in recent years. Each order has added to the boxes reaching Americans’ doorsteps, including containers that can be far bigger than the items inside.

Besides being better for the environment, the made-to-fit boxes can help companies cut shipping costs because the shipments take up less space in trucks and delivery vans.

Classroom discussion questions:

How do companies benefit from better packaging?
Are there other ways to improve packaging beside machines such as the one shown above?

OM in the News: China’s Dominance in the Rare Earth Supply Chain

The minerals, metals and rare earths needed for the green and digital transitions are shaping up to be the oil of this century—complete with a race to secure raw materials and production capacity at home or in friendly locations.

China has the early lead, writes The Wall Street Journal (March 9, 2023), dominating production of many critical materials including lithium and rare earths. Over the past years, China secured deposits around the world and invested heavily in the domestic manufacturing of clean technologies such as electric vehicles, batteries and solar panels. As the graph shows, China has a clear lead in the rare earth supply chain.

Western nations have now made it a top priority to secure a supply of these materials. The West has been tempted by the economic opportunity but also chastened by the recent semiconductor shortages, Europe’s efforts to replace Russian energy imports, and Beijing’s support for Russia after it invaded Ukraine.

Going back to President Trump, the U.S. signed executive orders for critical minerals– and has had recent success in starting to build local supply chains. The European Union’s latest effort—a Critical Minerals Act—aims to kick-start mining, processing and recycling in that region. There is one area where the EU act is right on the money—accelerating permitting. Permitting has been a key challenge for companies investing across geographies and sectors including mining, processing, power lines, solar, wind and batteries. In the EU, ambitious permitting reforms appears to be be the biggest hurdle to getting political agreement on that bloc’s local production of EV batteries. Limiting or overriding local opposition is rarely a vote-winning stance.

We may also get a G-7 critical minerals buyers club of the Group of Seven advanced democracies to secure supply from mineral rich countries in Africa, Asia and Latin America. Reduced Chinese supply—if it happens—will force Western policy makers and voters to face the trade-off between the carbon benefits of wind energy or electric vehicles and the environmental and pollution costs associated with manufacturing those technologies.

Classroom discussion questions:

Why are countries and companies so concerned about “rare earths”?
What is the main benefit in dominating the mineral supply chain?

OM in the News: Electric Cars and the Climate

An EV charging at a shopping center in California

Replacing all gasoline-powered cars with electric vehicles won’t be enough to prevent the world from overheating, says a new U. of California report. “The report offers a look at the environmental and economic sacrifices needed to meet net-zero climate goals,” writes The Wall Street Journal (Feb. 13, 2023).

The study notes three problems:

Problem No. 1: Electric-vehicle batteries require loads of minerals such as lithium, cobalt and nickel, which must be extracted from the ground like fossil fuels. If today’s demand for EVs is projected to 2050, the lithium requirements of the US EV market alone would require triple the amount of lithium currently produced for the entire global market. Unlike fossil fuels, these minerals are mostly found in undeveloped areas that have abundant natural fauna and are often inhabited by indigenous people. Mining can be done safely, but in poor countries it often isn’t.

Problem No. 2: Mining requires huge amounts of energy and water, and the process of refining minerals requires even more. Mining accounts for 4% to 7% of global greenhouse-gas emissions. Auto makers have made a priority of manufacturing electric pick-up trucks and SUVs because drivers like them, but they require much bigger batteries and more minerals. More mining to make more EVs will increase CO2 emissions. It will also destroy tropical forests and deserts that currently suck CO2 out of the atmosphere, the report says.

Problem No. 3: Producing EVs is an energy- and emissions-intensive process with high levels of embodied carbon. Electrification of the US transportation system will massively increase the demand for electricity while the transition to a decarbonized electricity grid is still underway.

The report concludes that the auto sector’s “current dominant strategy,” which involves replacing gasoline-powered vehicles with EVs without decreasing car ownership and use, “is likely incompatible” with climate activists’ goal to keep the planet from warming by more than 1.5 degrees Celsius compared with preindustrial times. Instead, the report recommends government policies that promote walking, cycling and mass transit.

Classroom discussion questions:

Comment on the report’s recommendations.
What can overcome the three problems cited?

OM in the News: Sprawling Supply Chains and Sustainability

Companies are rushing to more closely track materials across their sprawling supply chains ahead of expected new human rights and environmental laws, reports The Wall Street Journal (Jan. 24, 2023). Businesses, including consumer-goods company Unilever, clothing retailer H&M, and Renfro (which supplies socks to Ralph Lauren), say they are turning to technologies to help gather data on their supply chains and track materials.

Last year, H&M began rolling out a traceability platform for its recycled polyester and man-made cellulosic fibers, such as viscose, that can contribute to deforestation. It uses blockchain technology (see Chapter 11) to track and verify the use of sustainable fibers in garments. H&M has more than 600 commercial product suppliers who make their products in over 1,500 factories in Europe, Asia and Africa. The company says: “The closer we get to our 2030 goal for all our materials to be either recycled or sourced in a more sustainable way, the more traceability we gain.”

A host of supply-chain regulations went into effect in recent years and more are on the way, exposing companies to potential penalties and public criticism if found to be negligent. Many businesses, especially small and midsize ones, have a limited view of their supply chains and are struggling to broaden their oversight.

New European Union rules require larger companies operating there to identify, prevent and remedy risks to human rights and the environment in their supply chains, such as minimum age requirements, worker safety, pollution and biodiversity loss. There are a host of other regulatory developments threatening to affect companies’ supply chains. These include modern slavery laws in the U.S., such as the 2021 Uyghur Forced Labor Prevention Act.

Unilever has a sprawling global supply chain, with around 54,000 suppliers in 150 countries. The company tracks commodities such as palm oil and soy with satellites, geographical data and photos. But software that simply manages supply-chain data isn’t a silver bullet as it is difficult for companies to self-police the information they get from their suppliers. One startup, Wiliot, provides tiny tracking tags the size of postage stamps that can follow goods as they move, helping companies ensure materials aren’t coming from areas at risk of deforestation.

Classroom discussion questions:

What other regulations in the US and the EU govern industry sustainability standards? (Hint: see Supp. 5 in your Heizer/Render/Munson text)
Why are supply chains so difficult to manage with respect to human rights and the environment?

OM in the News: New York Goes After Cryptocurrency Miners

Bitcoin mines need cheap and plentiful electricity

Bitcoin mining – the process by which powerful computers solve complex mathematical equations to validate transactions is a crucial part of the cryptocurrency economy. And while amateurs could once mine coins at home, the complexity of equations, and the energy needed to solve them, has soared with the growing popularity and value of Bitcoin. We have twice posted blogs regarding cryptocurrency mining and its need for massive computers. (See “Going Crazy with Bitcoin Mining” on Nov. 15, 2021 and “Cryptocurrency’s Damage to the Environment” on April 19, 2021.)

But climate advocates have long said that the value of crypto–mining operations were not worth the environmental costs. The process requires an immense amount of electricity – so much so that China banned the practice last year in an effort to meet its climate goals.

New York became the first state to enact a temporary ban on new cryptocurrency mining permits at fossil fuel plants, a move aimed at addressing the environmental concerns over the energy–intensive activity, reports the New York Times (Nov. 22, 2022). The move in NY comes months after some other states (Montana and Georgia) and Quebec, Canada had adopted more friendly policies toward the industry, offering tax incentives in hopes of luring crypto-mining operations after China cracked down. “This bill will create the pause we need in the current trend of purchasing old power plants in New York for corporate profits and allow us to properly evaluate the impact of this industry on our climate goals before it is too late,” says a NY State legislator.

But it also comes at a moment of intense turbulence, and a potential crossroads, for the cryptocurrency sector. Earlier this month, the crypto exchange known as FTX suffered a swift and public collapse that led to its declaration of bankruptcy. The fall of what had been a trusted player in the new market has led to broader questions about the future of cryptocurrency.

The Chamber of Digital Commerce, a crypto advocacy group, denounced the NY bill as unfairly targeting the cryptocurrency industry, saying: “To date, no other industry in the state has been sidelined like this for its energy usage. This is a dangerous precedent to set in determining who may or may not use power.”

Classroom discussion questions:

1. Chapter 8 in your Heizer/Render/Munson text discusses location decisions based on government incentives. Relate that political issue to crypto mining.

2. What is your position on NY’s ban?
