Disruptive technologies can increase the intelligence of goods and revitalize business models in the circular economy. Applying an industrial ecology perspective, this article discusses how intelligent goods can boost the sustainability of industrial ecosystems. North American and European cases highlight how business model innovators can utilize goods-related information to develop more competitive closedloop systems. The authors identify three archetypes of closed-loop systems--inner circles, decentralized systems, and open systems--and delineate how they leverage information resources for collaboration. This study advances the understanding of closed-loop systems in the circular economy, which is more dependent than ever on digital platforms.

Extended Producer Responsibility (EPR) regulations require that producers organize and pay for treatment and recycling of waste arising from their products at end of life. EPR has been effective in implementing some aspects of circular economy. In Europe, 35% of e-waste and 65% of packaging waste have already been recycled (or reused in some cases). This article analyzes the challenges of implementing EPR and provides useful insights for what has worked well and what challenges remain. Identifying and addressing these challenges will be crucial for framing legislation that will move industry and society toward a more circular economy.

This article presents an in-depth case study detailing the history, experiences, and wider practitioner and policy lessons from a circular economy business model over a 30-year period, highlighting the successes, difficulties, and conflicts of adopting a circular economy model. The case is based on interviews, key documents, and customer insight. The findings demonstrate how sustained circular economy business practices can deliver significant new revenues, resource productivity, and business continuity benefits, but also require managers and practitioners to develop competencies and capabilities, such as balancing linear and circular systems, to address complex and highly dynamic factors, including rapid technological shifts and market volatility.

This article applies the Biosphere Rules--a biomimicry-inspired management framework for circular economy initiatives--to the emerging field of additive manufacturing and three-dimensional (3D) Printing, which are revolutionizing industrial sectors from medical devices to spare parts. They are also potentially keys in the emergence of a true circular economy that will bring about environmentally sustainable manufacturing. This article lays out an established strategy that can guide managers and policy makers in pursuit of a cradle-to-cradle economy.

Three-dimensional (3D) printing has been widely identified as an emerging disruptive technology. This study examines how this technology could enable the circular economy by disrupting the existing materials value chain. Specifically, could this novel technology be used to locally manufacture new goods from local sources of recycled plastic waste, thereby offering benefits for the efficiency and effectiveness of materials cycling? This article uses the London metropolitan area--where system conditions already exist in the form of material flows, technology policy, and facilities--in order to assess 3D printing's viability as an enabler of a circular economy at the local level. An analysis of stakeholder perceptions identifies economic, technological, social, organizational, and regulatory barriers to mainstream implementation, and their likelihood of being overcome.

This article explores how to get companies engaged in value-creating cooperation regarding residual materials. Within different contexts, industrial ecology needs matchmakers who act as network orchestrators to facilitate new forms of interorganizational cooperation on what were previously perceived as "junk materials." Three case studies of eco-industrial networks in Denmark (Kalundborg), Canada (the Québec region), and France (Dunkirk) demonstrate the various roles of the matchmakers to ensure the implementation of industrial ecology at the interorganizational level. This article highlights four strategic activities for matchmakers: revealing value in industrial ecology, generating trust, activating industrial ecology, and institutionalizing industrial ecology.

China's moves to introduce a Circular Economy have attracted wide attention as a solution to severe problems of resource inefficiency and lack of resource productivity. This article highlights the distinctive strategy of focusing such efforts on existing industrial parks, turning them into eco-industrial parks. It provides three case studies and highlights the management issues involved as overcoming reverse salients and capturing network advantages. China is an especially instructive case because it starts well behind the Organisation for Economic Co-operation and Development (OECD) countries and thereby has much to gain by adopting comprehensive policies.

Beef production is not sustainable, but it can and should be. Large scale commercial beef farming imposes tremendous negative impacts on the environment by polluting the air, water, and soil. In contrast, sustainable farming uses responsible practices that protect the environment for future generations. But, are consumers really interested in sustainable beef? When consuming sustainable beef products, most reactions by consumers are: they taste great; they are produced without destroying the environment or threatening public health; and their sales support responsible farmers who choose to use sound agricultural practices. Thus, if a sustainable farm wanted to promote one of its beef products, and it had to choose between "grass-fed", "pasture-raised" or "organic" beef, which one would it choose, at what cost, and at what risk? Such a decision is difficult without knowing analytics. So, can business analytics be used to evaluate such a business decision? This case is about making hard decisions involving sustainability products, for which business analytics can play a significant role. The intent is also to educate the reader about sustainability and sustainable beef. The case introduces an entrepreneurial start-up that consistently and successfully promotes sustainable farming, and it's their emphasis on sustainability that makes the company unique and successful. The decisions involve the sustainability "stamps" assigned to beef products. One may recognize some of these stamps, such as the "organic" brand. The farm in the case produces a variety of sustainable products, but it is thinking about a marketing campaign to promote one of its product stamps. But, which one? That is a hard decision, and it is where business analytics can play a role. Before we launch into the "meat" of the case, some background on sustainability and sustainable beef would be useful.

Esporte Interativo (EI) successfully launched and competed in the Brazilian sports television market for over 12 years. EI basically created the category (e.g., ESPN of Brazil) and came to prominence by televising the Champions League for European soccer, the National Basketball Association (NBA), and other sports content property. Since its founding, other television entities have recognized the potential for sports broadcasting which has dramatically driven up the cost of securing sports content. Edgar Diniz and Leo Lenz Cesar, co-founders and the CEO and CFO of EI, were pondering how to continue to compete and grow in an increasingly competitive space. The main decision point was whether to accept an offer from Turner Broadcasting Corporation to acquire EI.

In 2013, two entrepreneurs launched the Virtual Market in Mexico City with a mission to transform small traditional retailers (the so-called "mom-and-pop" shops) into competitive market players. The family-owned shops were strongly embedded in the society, culture, and economy of Mexico and Latin America, producing 50 per cent of the region's retail sales and 15 per cent of Mexico's true gross domestic product. However, economic growth had increased consumers' earnings, leading to previously low-income consumers gaining financial status. The traditional shops were unable to compete with the new demands for cashless payment methods, wider ranges of products and services, and lower prices. To remedy the situation, the Virtual Market gained the trust of the shop owners and worked to improve their financial, technological, and business literacy. By 2017, the Virtual Market had successfully worked with 10,000 shops but had still not attained break-even. Was its business model sustainable in the long term? Could it be replicated in other countries and with other cultures? How could it scale up and secure profits?

In August 2016, the global procurement manager at Hu-Friedy Mfg. Co., LLC, a large U.S. dental equipment manufacturer, realized that materials were being transported between suppliers and production facilities without a consistent strategy-potentially costing the company thousands of dollars each year. To evaluate the company's transportation needs, the manager considered a range of alternatives, including buying or leasing a truck or hiring a third-party logistics (3PL) provider to manage the transportation. To complete his analysis, the manager needed to develop a new set of routes for pickups and deliveries, evaluate the costs associated with owning or leasing a truck, determine the costs of a 3PL provider, and ultimately determine the course of action that would have the most impact on transportation costs with the least impact on daily operations.

The chief executive officer of Daimler Trucks and Buses China Ltd. was on an expatriate assignment in China. In November 2016, he faced a discomforting situation that could bring an abrupt halt to his career; an unfortunate incident in which he lost his temper led to fierce outrage in local Chinese and worldwide media. The media reaction threatened China's prominence as a major source of revenue for Daimler, and sent Daimler's share price on a downhill spiral. How should Daimler react, and what could it do to restore the company brand image?

In August 2015, a law student in Singapore came up with the idea for his first scooter when he needed a simple and economical mode of transport to get from his apartment to university. The student, who was Norwegian, and his Singaporean partner registered and incorporated Skutis Corporation Pte Ltd (Skutis) within only five days. The Skutis e-scooter emitted no fumes or noise and featured a quick folding design for easy storage. As new entrants in the industry, they felt confident that their combined study skills (law and business) would help them design and produce a more durable and dynamic scooter than those currently available. However, by April 2017, Skutis had already encountered major difficulties dealing with a Chinese manufacturer of its products. After 20 months of experience in the market, the two entrepreneurs were planning their company's strategy for the future. Having experienced the lows and highs of the Chinese production market, they were searching for ways to make their business more profitable and develop a long-term trustworthy relationship with a reliable manufacturer who would produce their designs.

In late 2012, an executive vice-president faced a dilemma at Industrias Metalúrgicas Pescarmona S.A. (IMPSA), an Argentine multinational company that designed and produced cranes, dams, and components for power plants, and had recently begun building hydroelectric and wind power projects. The company's chief executive officer had tasked the executive vice-president with recommending how IMPSA could be radically restructured to adapt to changes in the world marketplace for renewable energy. However, IMPSA was at the top of its game, and the company had a backlog of orders valued at US$3.3 billion. The executive vice-president knew that the chief executive officer would not accept a minor reorganization but would demand a major restructuring based on the firm's existing resources, which was a strategy that, in the past, had proven to be successful for the company, particularly in emerging markets. The executive vice-president wondered how IMPSA could build on its existing wind power and hydroelectric dam business without abandoning the resources the firm had developed over the years.

D. Sunil Reddy established Dodla Dairy in 1995 in Nellore district of the southern Indian state of Andhra Pradesh. An industrial engineer from Mangalore University, Sunil set up Dodla as a greenfield company at the age of 27 with seed money provided by his father. He was inspired by his grandparents and father to help those in need grow and flourish and by Mahatma Gandhi's call to "reach out to rural India". The company had grown well over the years. In fiscal 2015-16, it achieved an annual turnover of over INR 11 billion and aimed to touch INR 25 billion in revenues by 2020. It had a workforce of more than 2,000 employees, procured about a million liters of milk per day from 250,000 milk producers, and processed and sold milk and milk products at 67 locations in nine states in India. In 2011, Private equity fund Proterra invested INR 1.1 billion in Dodla, bringing down the family's shareholding from 100% to 76.34% (it would later go down to 72.3%). Sunil knew that if the company had to move to the next orbit, both in terms of size (revenues, assets and market share) and professionalization, certain organizational changes would be necessary. He wondered what these changes would be and who would make them. How could he better prepare himself and the company for the future? How would the company move from being a family-owned enterprise to a professionally run, sustainable organization? Would one of his daughters join the organization, bringing freshness to the company while providing continuity in terms of family values? Would the company be run by an outsider? "Who after me?", thought Sunil. He often wondered whether the brand "Dodla" and the company he had founded would sustain beyond himself. While he continued his efforts to increase capacity, expand and capture more market share, he kept asking himself, "What next" and "How do I build a legacy?

Alice Monroe, a 30-year-old married mother of two, was an admissions officer at the Kellogg School of Management at Northwestern University. She was just completing her first year of service at Northwestern and qualified for the university's 403(b) retirement plan. It was early October 2017, and she had until the end of the month to decide if and to what extent she would participate in Northwestern's retirement plan--that is, how much of her salary should she put into the retirement plan, and into which mutual fund or funds should she allocate her savings? The case includes background on defined contribution and benefit plans as well as mutual funds. It goes into detail about Northwestern's retirement plan, including data on the performance of 15 of the plan's core mutual funds. The case also provides each fund's strategy, Morningstar Rating and Morningstar Category, expense ratio, assets under management, turnover rate, and historical performance for the last 10 years. Using modern portfolio theory (diversification and risk-return trade-off) and with an understanding of mutual fund fees and the tax advantages of retirement savings, students will decide how much Alice should invest and in which mutual funds.

Supplement to case KE1056. Alice Monroe was an admissions officer at the Kellogg School of Management at Northwestern University. It was early January 2017 and Alice had enrolled in Northwestern's 403(b) retirement plan two months earlier. After spending a considerable amount of time examining the mutual funds available through the university's retirement plan, Alice had picked two to invest in: a large-cap equity growth fund and a mid-cap equity fund. (See the related case "Selecting Mutual Funds for Retirement Accounts (A).") Her initial allocations were 50% of her investment dollars in each fund. Upon further reflection, however, she realized these initial allocations were somewhat simplistic. She recalled, from an investments class she had taken at college, the topic of modern portfolio theory, which held that by adding more funds to her portfolio she might be able to achieve greater diversification and thereby reduce the overall risk of her portfolio and/or achieve a higher expected return. Alice now was considering adding an intermediate-term bond fund and a real estate fund to her retirement account. She hoped to use modern portfolio theory to prove that these new funds would indeed help her diversify her portfolio. If they did, she would also reassess her portfolio weights to determine the optimal allocation.
