Classify each example as Circular, Linear, or Hybrid — discuss with your group before clicking. Be prepared to justify your classification using conceptual language, not just intuition.
Display the diagram of linear vs. circular economy before opening this tab — available as a flowchart handout. After the game, ask: "Which model do we use more today, and why has it persisted despite its evident limitations?" Elicit structural, economic, and behavioural explanations. Encourage use of hedging: "One might argue that..." / "It tends to be the case that..."

The Circular Economy Paradigm: Theoretical Foundations and Practical Limitations
The concept of the circular economy has tended to attract considerable attention in both policy and academic circles over the past two decades, yet its theoretical coherence and practical feasibility remain subjects of ongoing scholarly debate. At its core, the model proposes a fundamental departure from the prevailing linear paradigm — characterised by the extraction, processing, use, and disposal of materials — in favour of closed-loop systems designed to maintain the utility and value of products, components, and materials for as long as technically and economically viable.
Proponents of the circular model, most notably the Ellen MacArthur Foundation (2013), have argued that transitioning to circularity could generate substantial economic benefits while simultaneously reducing environmental pressure. Such projections, however, are contingent upon a set of enabling conditions — including regulatory frameworks, consumer behaviour change, and technological innovation — that cannot be assumed to materialise spontaneously. Indeed, it may be argued that the circular economy, as currently practised, tends to operate at the margins of the existing linear system rather than transforming it structurally.
From a critical perspective, a more nuanced interpretation of the evidence suggests that recycling rates alone represent an insufficiently ambitious metric by which to evaluate circular economy progress. Lifecycle analysis — which accounts for the full environmental burden of a product from material extraction to end-of-life management — reveals that the efficiency gains achievable through circular design may be substantially offset by rebound effects, whereby efficiency savings are reinvested in additional consumption. This phenomenon, widely described as the Jevons Paradox, poses a significant challenge to the assumption that technical solutions alone can deliver the scale of systemic change required.
Notwithstanding these theoretical concerns, the circular economy framework has demonstrated considerable practical utility at the firm and city level, where localised interventions in product design, material recovery, and industrial symbiosis have produced measurable and replicable outcomes. Whether such localised successes can be meaningfully scaled to address the systemic drivers of global material throughput growth, however, remains an open and contested question in the literature.
After reading, elicit examples of each highlighted structure and ask: "What does the author gain by hedging rather than asserting directly?" At C1 level, students should understand that hedging signals intellectual rigour, not uncertainty or weakness. Use the Hedging Builder for guided practice before the Jigsaw task.

IKEA, the world's largest furniture retailer, has committed to becoming a fully circular business by 2030 — a pledge that entails redesigning all products for longevity, repairability, and eventual material recovery. Central to this strategy is the company's buy-back scheme, operational in 37 countries, whereby customers return used IKEA furniture in exchange for store credit. The returned items are subsequently resold in a dedicated second-hand section, refurbished if necessary, or broken down into component materials for recycling.
The initiative reflects the three core principles of circular product design articulated by the Ellen MacArthur Foundation: designing out waste, keeping products and materials in use, and regenerating natural systems. In practice, however, the programme's environmental impact is qualified by several structural constraints. IKEA's core business model relies on high-volume, low-cost production — a model that, some critics argue, is inherently in tension with the principles of longevity and material quality that a genuinely circular system would require.
Furthermore, the company's carbon footprint remains substantial, with Scope 3 supply-chain emissions dwarfing any gains attributable to its buy-back initiative. Notwithstanding these limitations, IKEA's programme represents one of the most visible and large-scale corporate circular economy interventions to date, and has been credited with raising consumer awareness of furniture lifecycle issues in markets where disposal had previously been the default behaviour.
Amsterdam is widely regarded as the world's most advanced municipal circular economy initiative. In 2020, the city adopted the Doughnut Economics model — developed by economist Kate Raworth — as its official governance framework, committing to meeting the social needs of all residents without exceeding the ecological boundaries of the planet. The strategy operationalises circularity across five material chains: food and organic waste, consumer goods, built environment, plastics, and textile and apparel.
The built environment strand, in particular, has attracted international interest. Amsterdam has introduced mandatory urban mining clauses in demolition contracts, requiring that 80% of all demolition waste be recovered and reprocessed before new construction permits are issued. This has catalysed a nascent secondary materials market in which surplus building materials are traded, creating economic value from what would previously have been classified as waste.
The initiative's success has been attributed to a confluence of enabling conditions rarely present simultaneously: a coherent policy framework that extends across multiple city departments, sustained political commitment across electoral cycles, and a civic culture in which sustainability is deeply embedded as a social norm rather than merely an aspiration. Critics, however, have noted that Amsterdam's approach is difficult to replicate in cities with more fragmented governance structures or lower baseline levels of environmental consciousness — raising important questions about the scalability of place-based circular economy models.
The Repair Café movement, founded by Martine Postma in Amsterdam in 2009, represents a grassroots, community-led application of circular economy principles. Repair Cafés are free community spaces in which volunteers with technical skills assist members of the public in repairing broken objects — from clothing and electronics to furniture and bicycles — that would otherwise be discarded. By 2024, over 2,500 Repair Cafés operate in more than 40 countries, collectively diverting an estimated 1 million objects from landfill annually.
The movement embodies several principles that formal corporate and municipal circular economy initiatives frequently struggle to operationalise: the revaluation of skilled labour, the democratisation of technical knowledge, and the cultivation of emotional attachment to objects as a barrier to premature disposal. In this sense, Repair Cafés address what might be termed the “behavioural gap” in circular economy transitions — the persistent disconnect between individuals' stated environmental values and their consumption behaviour.
Notwithstanding the movement's evident social value, its aggregate environmental impact remains modest relative to the scale of global waste generation. Repair Cafés are, by design, highly localised and volunteer-dependent, rendering them difficult to scale without fundamentally altering the conditions that give rise to their distinctive social character. Critics have argued that, in the absence of complementary policy interventions — such as right-to-repair legislation and extended producer responsibility regulations — repair-based approaches risk becoming marginal supplements to, rather than structural alternatives for, the prevailing disposal economy.
