A practical way of defining circular economy is that it is based on the principles of designing out waste and pollution, keeping products and materials in use, and regenerating natural systems. To make it simple, circular economy is about sharing, renting, mending, borrowing, redesigning and recycling. It is the new way of doing things, instead of the old “wear and tear” behavior.

#1 Resource intelligent economic model. This is a fundamental concept of circular economy. It enhances natural capital and creates the necessary conditions for the regeneration of natural systems. Circular economy is resource intelligent and regenerative & takes notice of the nature’s capacity. Operations within planet’s boundaries.

#2 Extension of the life of products and materials. This means that circular economy aims to extend the useful life of the products and materials by creating the loops of the materials and products. They are kept in use endlessly in biological or technical cycles. The goal is achieved through the active reuse, repair and re-manufacturing of the products and materials utilized in the economy. Materials are safe & non-toxic.

#3 Minimization of waste and pollution. This is important both in production and when using the products. Value of products, components and materials is maintained and increased through refinement.

#4 All energy is renewable and is used efficiently.

#5 Solutions are systemic and based on the good planning of life-cycles, ecosystems and multi-purpose usage patterns.

#6 Resources and well-being are equally divided for all. ⁴

In a circular economy, businesses build and rebuild overall health and well-being of the planet and people. The concept recognizes the importance of the economy needing to work effectively at all scales – for large and small businesses, for organisations and individuals, globally and locally.

Transitioning to a circular economy does not only amount to adjustments aimed at reducing the negative impacts of the linear economy. Rather, it represents a systemic shift that builds long-term resilience, generates business and economic opportunities, and provides environmental and societal benefits.

In sifting to the circular economy business it is also important to understand the concept of closed loops. Closed-loop recycling is the process by which a product or material can be used and then turned into a new product (or converted back to raw material) without losing its properties. Closed loop minimizes the harms to the environment and reduces the need to use new natural resources. Ideal closed-loop systems produce no waste.

For making the closed loops possible the companies need to review and make changes to all their operations like logistics, sorting, warehousing, energy supply sourcing, marketing and management in order to make the change. According to Ellen Mac Arthur Foundation, the Circular Economy system framework is divided into two parts, biological cycles and technical cycles. It is very important that the businesses and consumers  understand the difference of these processes, to enable “zero waste”.

Reverse logistics is defined as the process of moving goods beyond their typical final destination for purposes like re-use, capturing value, or proper disposal. This can include all recycling, reclamation of raw materials, refurbishment, and reselling of items that have been stocked again.⁷  In supply chain networks, materials flow from suppliers through to end customers and back to being re-processed. This is important to make the closed loops function.

The “Butterfly-model” differentiates the biological and technological cycles

• In biological cycles the nature-based and bio-degradable raw materials circulate. For example food and other natural materials (such as cotton or wood) are planned to feed back into the system through processes like composting and anaerobic digestion. These cycles regenerate living systems, such as soil, which provide renewable resources for the economy.
• Technical cycles cover materials produced by the humans, harmful materials like e.g. technology, metals etc. These materials can be recovered and restored into new products/components  through strategies like reuse, repair, re-manufacture or (in the last resort) recycling.
• In technical cycles materials are created by people in the industrial processes. Original materials are also derived from the nature, but they are processed so that the new materials cannot be returned safely to the nature anymore. These produced materials  should be circulated, processed and re-used in a way that the need for using new original materials decreases into minimal. For example scarce mineral resources like metals can be collected from electronics and re-used in the new products. The goal for these cycles is 100% reuse. These materials altogether should be kept totally separate from the nature’s cycles. An example of this is keeping the plastic in a closed cycle because the effects of micro-plastic is hazardous to the environment. ⁵

Practical examples of how circular economy cycles can be taken into account in the product development:

Life Cycle Model

Life-cycle Model helps companies to analyse current products and services and future opportunities. In the beginning of the development process the company should view and evaluate step by step all the core processes, customers and usage and evaluate what should be changed. The circular economy business can be worked in each part of the company’s value chain which is described in the picture below. Life cycle model is often associated with the so-called life cycle assessment (LCA) which is explained in a later chapter.

Below there are some examples of questions in this value chain to be asked regarding the process of the full evaluation of the current business. Please click the info-button (i) to read the details.

“A good life is no longer achieved by simply producing more and more goods”. “How do we move to a circular economy, in which consumption is based on using services – sharing, renting and recycling?” So what is circular economy?

Circular economy is an economic model which does not focus on producing more and more goods, but in which consumption is based on using services – sharing, renting and recycling – instead of owning. Materials are not destroyed in the end, but are used to make new products over and over again. Circular economy solutions are needed to safeguard biodiversity and solve the climate crisis. It is about turning the inefficiencies in the companies’ linear value chains into new sustainable business value.

This video explains shortly but concretely what circular economy is all about. Start by watching it before reading the next:

• The circular economy is an economy in which stakeholders (companies, authorities, others)  collaborate efficiently in order to maximize the value of products and materials, and as such contribute to minimizing the depletion of natural resources and create positive societal and environmental impact.
• Looking beyond the standard of “take-make-waste” industrial and consumption models, the circular economy aims to re-define growth, focusing on positive society-wide benefits. It brings along gradually decoupling economic activity from the consumption of scarce resources, and designing waste out of the system.
• In circular economy, economic activity builds and re-builds overall health to the business. The concept recognizes the importance of the economy needing to work effectively at all places – for large and small businesses, for organisations and individuals, globally and locally.

We are shifting to a system where we

• design new products out of waste and pollution
• keep products and materials in use indefinitely
• regenerate natural systems

Transitioning to a circular economy (from the linear economy) does not only amount to adjustments aimed at reducing the negative impacts of the linear economy. Rather, it represents a systemic shift that builds long-term resilience, generates business and economic opportunities, and provides environmental and societal benefits. ¹

The circular economy responds to the largest global challenges such as climate change, depletion of natural resources, and loss of diversity. Achieving circular economy objectives requires new kinds of thinking and operating models, diverse expertise and a reorientation of business activities. In particular, different kinds of professionals are needed who can solve the difficult problems related to circular economy implementation.
