Introduction
The traditional linear economy operates on a take-make-waste model, where materials are extracted, consumed, and thrown away. The result – mountainous waste landfills. This approach depletes finite resources, produces toxic waste, and contributes to pollution. Moreover, it squanders the potential value of a product by discarding it before the end of its material life cycle. The excessive use of resources and relentless economic activity centered on consumption compound issues such as toxic pollutants, unmanageable waste, poverty, resource scarcity, global warming, and climate change. Fortunately, one of the solution exists in the concept of Circular Economy.
What is Circular Economy
Circular Economy is an economic model based on the principle of reuse and regeneration primarily as means to continuing production in a sustainable and environment friendly way.
Circular Economy from Nature Based Solutions
The concept of circularity, sustainability and resilience is deeply rooted in the observation and study of nature and its ecosystems. Over billions of years, life on Earth has evolved, adapting, redesigning, and transforming to survive across diverse and challenging environmental conditions. This long evolutionary journey highlights that nature embodies some of the most effective designs, engineering principles, and biological solutions to the challenges of life.
In the natural cycle of life, organisms consume resources, live their lifespan, and, upon death, return to the soil, fostering regeneration and supporting new life. Energy and essential material constituents, such as carbon and nitrogen, continuously flow through the geosphere, biosphere, and atmosphere, ensuring a seamless and cyclical process. Even waste is not discarded but instead becomes a vital component of this cycle, as nutrients are absorbed and reintegrated into the ecosystem. This interconnected process ensures balance and wholeness, maintaining the resilience and sustainability of natural ecosystems.

The concept of the circular economy seeks to mimic the regenerative patterns observed in nature, where resources are continuously reused and repurposed. Historically, societies and civilizations have practiced similar principles, driven by constraints such as resource scarcity, necessity, and sustainability. These practices involved reusing, repairing, and recycling materials to extend their utility and minimize waste. The circular economy builds on these age-old strategies, applying them in a modern context to create a more sustainable and efficient system for managing resources.
The circular economy is a developing economic model based on similar principles and holds the potential to reduce waste, pollution, and carbon emissions, while also enhancing the life-cycle and value of material products through the evolution of the entire economic system.
The Origin of Circular Economy
The practices of careful use, repair, reselling, reuse, and recycling of materials have always been present in human societies. However, the concept of the circular economy as a structured model began to take shape in the 1960s and 70s when thinkers like Walter Stahel and others proposed ideas such as the “cradle-to-cradle” model. Unlike the linear economy, which follows a take-make-waste approach, this model considers the entire life cycle of a product, envisioning a continuous loop where resources move from one consumer to another, minimizing waste.
By the 2000s, the circular economy model was adopted by China as part of its national policy, marking a significant step in integrating these principles into large-scale governance. Around the same time, the Ellen MacArthur Foundation was established in 2010 with the mission to accelerate the global transition to a circular economy. The foundation gathers data and provides knowledge about the circular economy, uniting businesses, policymakers, and academia to develop practical frameworks and strategies that drive innovation, reduce waste, and address global challenges like climate change and resource depletion.
The circular economy aligns with several complementary economic concepts, such as industrial ecology, biomimetics, and the performance economy, each contributing unique perspectives to its framework. By integrating these approaches, the circular economy becomes a powerful tool for achieving sustainability, reducing environmental impact, and combating climate change. Its emphasis on resource efficiency, waste reduction, and regeneration makes it an essential alternative to traditional economic models, paving the way for a more sustainable and resilient future.
How Does Circular Economy Work ?
The circular economy is centered on two main components: the biological cycle and the technical cycle, as illustrated in the Butterfly Diagram by the Ellen MacArthur Foundation. This model emphasizes regenerating natural systems and maintaining the value of resources in closed loops to achieve sustainability.
Biological Cycle in Circular Economy
The biological cycle in the circular economy focuses on renewable resources such as food, natural fibers, and wood-based materials. Products made from these resources are designed to safely return to the environment after use, mimicking nature’s regenerative processes. When these products decompose, they break down into nutrients that enrich the soil and support the growth of new resources. For example, organic waste, such as food scraps, can be composted or processed in anaerobic digestion systems to produce biogas and nutrient-rich compost. This cycle ensures that natural systems remain replenished and sustainable, promoting biodiversity and ecosystem health.
Technical Cycle in Circular Economy
The technical cycle, on the other hand, addresses non-renewable resources like metals, plastics, and synthetic materials. In this cycle, products and materials are designed for reuse, repair, refurbishment, remanufacturing, or recycling, ensuring that they remain in circulation for as long as possible. For instance, used electronic devices can be disassembled, with functional components extracted and repurposed for manufacturing new devices. By keeping valuable materials within closed loops, the technical cycle reduces waste, minimizes the need for extracting virgin resources, and preserves the inherent value of non-biodegradable materials.
Goals and Processes of the Cycles
The biological and technical cycles aim to complement each other by addressing different types of resources. The biological cycle prioritizes regenerating ecosystems and enhancing natural systems, while the technical cycle focuses on maintaining the value of materials in human-made systems. Both cycles emphasize designing products and systems that reduce waste and extend resource lifespans. This dual approach highlights the importance of rethinking product design and material flows to create a system where waste is minimized and resources are used efficiently.
Interconnection and Balance
The circular economy’s butterfly diagram showcases the interconnectedness of the biological and technical cycles, underlining how human activity and natural systems can coexist sustainably. The biological cycle regenerates nature, while the technical cycle promotes responsible material use, innovation, and value retention. Together, these cycles form a holistic approach to sustainability, balancing economic activities with ecological health. This synergy helps address environmental challenges like waste generation, resource depletion, and climate change while fostering economic growth and innovation.
Conclusion
The circular economy is a forward-thinking approach designed to create sustainable solutions for pressing global challenges. By addressing issues such as climate change, it seeks to reduce waste, maximize resource value, and generate job opportunities, fostering a more sustainable and environmentally friendly future. This model encourages creativity and innovation to develop systems and products that balance economic growth with ecological health, offering a hopeful and practical path toward building a better future for both people and the planet
