Circular economy sustainability: rethinking growth and resource use

Explore the transformative potential of the Circular Economy Sustainability, a groundbreaking approach that rethinks growth and resource use. Learn about its core principles and practical examples in the food industry. Find out how it can lead to a more sustainable and environmentally responsible future.

As people become more concerned about taking care of the environment, the idea of the “circular economy” is becoming more important. It’s not just a passing hype, but a big change in how we think about economic growth and using resources. In this article, we’ll explore what the circular economy is all about, its main ideas, and how it affects different industries, especially the food industry. We’ll also look at some real-life examples and projects, the upcoming European regulation, and new technologies like blockchain for food and waste traceability.

What does circular economy mean?

In a conventional “linear economy” model, companies collect and transform raw materials into finished products, and then dispose of the waste. In a circular economy model the waste generated in the process is reused, regenerated and recycled

Which are the 4 main concepts of circular economy?

The circular economy and sustainability are intrinsically tied to each other. It offers a path to economic growth that does not compromise the well-being of future generations. By minimizing waste and maximizing resource efficiency, it reduces the environmental impact of economic activities. This not only aligns with sustainability goals but also contributes to a more resilient and less resource-dependent economy. To better understand the circular economy, it’s essential to grasp its four main concepts:

  • Resource Sharing:

also called sharing economy, prevents resources from sitting unused. The approach encourages the exchange and sharing of products, and services in order to maximize resource utilization and reduce waste. Many worldwide successful examples are already car-sharing or car-pooling as well as shared farm equipment or the practice of distributing surplus food through applications like TooGoodToGo. The circular economy in agriculture can minimize the need for additional machinery, while for city dwellers, it allows them to rent a car near their location for the time they require, reducing costs, risks, and pollution.

  • Promoting Circularity:

Circular economy principles drive production models that minimize resource consumption, promote product reuse or waste repurposing, and facilitate plastic and organic material repair or recycling. A notable example lies in designing easily recyclable or reusable products and packaging, such as recyclable packaging or the transformation of organic food waste like orange peels, grape pomace, or apple peels into fiber fabrics or paper materials.

  • Transition to Renewable Energy Sources:

Another main pillar of the circular economy is the adoption of renewable energy sources as the primary energy supply. The central goal of the circular economy is to maintain the value of resources (products, components, and materials) for as long as possible. This requires a complete transformation across the entire production chain, from product design that makes disassembly easy to the use of renewable energy sources. An example applied to renewable energy is cogeneration plants, meaning that the heat produced for generating electricity is reclaimed and reused for generating thermal energy, optimizing energy efficiency.

  • Valuing Natural Capital and Sustainability for a Long-Term Vision:

Sustainability refers to the ability to meet present needs without jeopardizing the capacity of future generations to meet their own. Sustainability goes beyond just environmental concerns; it also covers social equity and economic efficiency. It underscores the need to preserve and restore the ecological balance of the environment. In the agricultural sector, this could translate into decreasing pesticide use and championing eco-friendly farming methods. The transition to sustainable agricultural practices contributes to conserving natural resources, reducing environmental impact, and protecting biodiversity. This brings food production in line with environmental sustainability while safeguarding natural resources—a critical move towards the future and the generations to come. These practices ensure that food production and environmental preservation go hand in hand.

What are the 3 principles of circular economy?

At its core, the full cycle of the circular economy revolves around the principles of smart design, optimal utilization, reuse, and recycling. These principles form the linchpin of a more sustainable and environmentally-friendly economic system. This system is driven by a commitment to minimizing waste, extending the lifespan of products and materials, and fostering a regenerative relationship with our environment.

The circular economy is guided by three fundamental principles:

1) Eliminate Waste and Pollution: the first fundamental principle of the circular economy is centered around the proactive elimination of waste and pollution. It calls for designing products, processes, and systems in a way that minimizes waste generation and reduces pollution. The aim is to create a closed-loop system where resources are conserved, and environmental impact is minimized. This not only benefits the environment but also improves economic efficiency by cutting down on disposal costs and raw material consumption.

2) Circulate Products and Materials at Their Highest Value: this principle emphasizes the continuous circulation of products and materials at their highest utility and value. In contrast to the traditional linear economy, where products are discarded after use, the circular economy strives to extend the life of products through strategies like repair, refurbishment, and remanufacturing. This approach ensures that resources are used to their maximum potential. It’s a model that benefits both businesses, as it reduces resource costs, and consumers, by providing more durable and high-value products.

3) Regenerate Nature: the third principle is the regeneration of nature. In a circular economy, the focus is on restoring and regenerating natural systems and maintaining biodiversity, ensuring that our resource consumption is balanced with the Earth’s capacity to regenerate those resources. This means embracing sustainable practices that minimize harm to the environment and promote ecological balance.

Circular Economy in the Food Industry

The food industry contributes to significant waste but also faces growing challenges associated with resource scarcity and climate change. Here, the concept of a “circular food economy” comes into play.

To understand how the circular economy is applied in the food industry, consider the following practical examples:

  • Blockchain Food Traceability: Blockchain technology paired with IoT technology is used to track the journey of food products from farm to table. This not only enhances supply chain transparency but also enables faster product recalls by identifying the exact real-time location of contaminated products.
  • Wines Digital Product Passport: Some winemakers are utilizing digital product passports for their wines. These passports contain information about the wine’s production, including its origin, ingredients, and sustainability practices. This transparency supports both consumer choices and sustainable production.

The benefits of implementing a circular economy in the food industry are vast and multifaceted. Some of the advantages include:

  • Reduced Food Waste: Through practices like recycling food scraps into compost or animal feed.
  • Sustainable Agriculture: Promoting sustainable agricultural practices ensures the long-term health of ecosystems and food production.
  • Resource Efficiency: By minimizing waste and reusing resources, the food industry can operate with greater resource efficiency.
  • Economic Growth: The circular food economy can stimulate economic growth through innovation and job creation in areas such as food recycling and sustainable agriculture.

Led by the European Commission, the EU Circular Economy Action Plan is a detailed strategy to incentivize enterprise adoption of circular economy. This plan sets ambitious targets for reducing waste, promoting recycling, and encouraging reuse. It also explores new ideas like using blockchain technology for transparent wine traceability and e-labeling. The goal is to create a greener and more sustainable future. With all the environmental challenges we’re up against, the circular economy offers a hopeful way forward.
