The circular economy, a concept with deep roots in the 1970s, emerged as a response to environmental challenges and the depletion of natural resources. In this article, we will explore the key steps that marked the birth and evolution of this innovative economic perspective, analyzing how it moved from theory to practice, transforming from a simple idea into a global movement.
In the 1970s, a period when environmental awareness was gaining momentum, the concept of the circular economy emerged. Walter R. Stahel was one of the pioneers, introducing the notion of the “economy of listening.” During this time, society began to reflect on the need for more sustainable resource management and on reducing the environmental impacts linked to traditional economic models. The Ellen MacArthur Foundation is the most well-known non-profit organization worldwide promoting the circular economy, inspiring and encouraging companies and institutions to adopt sustainable models and reduce waste.

Theory and early approaches

In 1966, Kenneth E. Boulding proposed the idea of a circular flow of materials in “The Economics of the Coming Spaceship Earth.” In 1976, Walter Stahel and Genevieve Reday, in a report to the European Commission, explored substituting manpower for energy, anticipating the circular economy and its benefits in terms of employment, resource savings, and waste reduction. This research was later published in 1982 in the book “Jobs for Tomorrow: The Potential for Substituting Manpower for Energy.” Stahel and other theorists of the time promoted business models focused on maximizing the value of products and materials. This period marked the beginning of a shift in perspective, with growing emphasis on designing products that could be easily repaired, reused, or recycled. The concept of a “full life cycle” became a mantra, anticipating future circular economy practices.

1980s–1990s: early practices and environmental regulations

During the 1980s and 1990s, attention to the circular economy grew. Stahel’s ideas were explored in greater depth, with increased emphasis on recycling and reuse. Meanwhile, environmental regulations began to emerge, encouraging more sustainable practices. Companies and governments started to seriously consider implementing waste management policies and introducing incentives for eco-friendly design.

Early 21st century: growing interest and sustainable policies

The new millennium saw increased interest from businesses and governments in the circular economy. Implementing sustainable policies became a priority, with a strong focus on waste management and promoting more responsible practices. Sustainability was no longer just an option but a necessity in a world facing growing environmental challenges.

Recent acceleration

In recent years, the circular economy has experienced significant acceleration, fueled by technological advances. The Internet of Things and artificial intelligence have enabled greater traceability and material management, facilitating the shift toward more circular models. Growing consumer awareness of sustainability has also driven companies to adopt more eco-friendly practices.

Key elements of the circular economy

Today, the circular economy is based on several key elements. Circular design is crucial, with the creation of products that take their full life cycle into account. Reuse and recycling are actively promoted, extending product life and recovering valuable materials. In addition, the idea of a service-based economy is gaining ground, shifting from the traditional product sales model toward service provision. According to the Ellen MacArthur Foundation, in the circular economy, materials follow two pathways: biological ones, reintegrated into the biosphere, and technical ones, revalorized without impacting the biosphere.
According to the Ellen MacArthur Foundation, the core principles of the circular economy are:

• Design for longevity: products and services should be designed to last as long as possible and to be easily repairable, renewable, or recyclable.

• Maintain resource value: resources should be kept in the economic system for as long as possible, minimizing waste.

• Reduce waste: waste should be minimized through reuse, recycling, and material recovery.

• Resource use efficiency: resources should be used efficiently, avoiding waste and loss.

• Renewable energy: energy used in the economic system should be renewable and clean.

These principles are based on the “cradle-to-cradle” concept, often abbreviated as C2C. In a circular economy, products and materials should be designed to be reused or recycled so they can re-enter the economic cycle without becoming waste.
Implementing circular economy principles can lead to numerous benefits, including:

• Reduction of pollution and waste
• Conservation of natural resources
• Job creation
• Sustainable economic development

Recognized benefits of the circular economy

The benefits of the circular economy are now globally recognized. Reducing waste and pollution, along with conserving natural resources, are key objectives. In addition, the circular economy stimulates innovation, encouraging the creation of new business models centered on sustainability.

Challenges and future outlook

However, challenges remain. Overcoming logistical barriers, implementing economically sustainable business models, and fostering collaboration between public and private sectors are essential for the long-term success of the circular economy. The ongoing pursuit of new technologies and innovative approaches is vital to address emerging challenges and ensure a sustainable future.

Conclusion

The circular economy has evolved from a theoretical concept to a concrete movement transforming our view of the economy. With a history spanning decades, it is clear that its evolution has been a complex and inspiring journey. Looking ahead, it remains a key element in addressing environmental challenges and building a more sustainable world for future generations.
