As John Elkington, a world authority on corporate responsibility and sustainable capitalism, once said, "The circular economy is not just about closed loop recycling; it is about closed loop design." We live in a world of finite resources, yet operate under an economic model that values consumption—a model that is no longer sustainable. The concept of a circular economy offers an alternative path.

A circular economy, as defined by Accenture, moves beyond the traditional 'take-make-dispose' linear model to one that is regenerative by design. The goal is to retain as much value as possible from resources while in use and recover and regenerate products at the end of their service lives. This shift in economic thinking presents both challenges and opportunities for companies— and their leaders— who are willing to innovate and commit to a more sustainable way of doing business.

In a report by McKinsey & Company, four key components that characterize circular economy business models were identified: circular supplies, resource recovery, product life extension, and sharing platforms. The adoption of these principles is not just right for the environment but also potentially profitable. According to the World Economic Forum, the circular economy could generate $4.5 trillion of additional economic output by 2030.

• Circular Supplies: This entails the use of renewable, bio-based, or fully recyclable materials to reduce dependence on raw extractions. A good example of this is Apple's commitment to use 100% recycled or renewable materials in its products and packaging.
• Resource Recovery: This includes innovative ways to recover and reuse by-products, waste, and energy. Companies like Tesla are already capitalizing on this through their energy storage and recycling programs.
• Product Life Extension: This includes methods for extending the life of products, such as repair, upgrading, remanufacturing, or remarketing. As a leading example, Patagonia operates a repair and reuse program for its apparel products.
• Sharing Platforms: These models are designed to maximize the utilization of assets by enabling shared use/access/ownership. Consider Uber and Airbnb, which have become global giants by leveraging the sharing economy.

To successfully implement a circular economy strategy, strong Leadership and Culture is vital. Deloitte's 2018 Global Chief Procurement Officer Survey revealed that 64% of CEOs cite 'circular economy' as a top priority. This requires a holistic viewpoint, where sustainability isn't an appendage but a core part of Strategy Development and Risk Management within an organization.

Moving towards a circular economy requires Innovation and a rethinking of traditional business models. In a study by MIT Sloan Management Review, it was found that organizations who engage in 'serial innovation'—the continuous and intentional process of changing and re-evaluating business models—are more likely to find success with implementing circular economy practices.

As digital accelerates our consumption and waste, the transition to a circular economy becomes more critical than ever. In a report by The Boston Consulting Group (BCG), transitioning to a circular model can offer companies numerous benefits, such as reducing cost, mitigating risk, and driving innovation. The shift can also foster a more positive brand image, improve customer relations, and act as a driving force for change within industries.

A Goldman Sachs report observes the circular economy as an economic opportunity, a tool for risk management, and an avenue towards achieving sustainability goals. This shift reflects not just a transient trend, but a fundamental change in the way we conceptualize and conduct business.

To close this discussion, the need for a circular economy has never been more urgent. By adopting circular economy principles, businesses can foster a culture of innovation, enhance customer and stakeholder relationships, and contribute to making the world a more sustainable place for future generations.
