The production process is no longer a classical linear pattern, but a virtuous cycle of circuits, inflows and outflows, forming a closed ecosystem.
Linear economic model
Linear models, which have been widespread since the Industrial Revolution, face limitations, facing resource shortages, environmental impacts, and global population growth.

Circular economy model
Circular economy players are developing collaborative strategies that are interested in achieving quantifiable resource savings, especially through waste recovery and energy flow optimization.
Circular Economy Diagram (from “Circular Economy”, Rémy LeMoigne, Dunod Edition)
The circular economy is characterized by various founding principles that help minimize the use of non-renewable resources and achieve energy savings at various stages of the process.
- Eco design : A resource-efficient design that prioritizes repair, dismantling, and recycling while maintaining the original quality and performance of the product.
- Industrial ecology : Optimization and replacement of “material” and “energy” resources used in the production cycle (above).
- Reuse : Repair or disassembly of functioning parts.
- recycling : Reuse of raw materials from waste.
The circular economy, which facilitates short production and consumption circuits, involves cooperation among all economic players at the territorial level, far beyond manufacturers.
In France, the Commission on Sustainable Development estimates that all waste generated can provide almost 40% of the “materials” needed for our economy.Currently, only 42% of recycled raw materials (MPR) are used(2)..
Models applied on a regional scale: industrial areas, cities, sectors, etc.(3)
Inspired by the functioning of natural ecosystems, the circulation model reproduces an organization on the scale of an industrial system, characterized by optimal use of resources and high recycling rates of materials and energy.
Specifically, this involves developing synergies for economic players to locally reuse production residues and encourage them to pool specific services and equipment. The purpose is to tend towards short-circuiting and closing cycles of physical flow on a territorial scale, thus limiting resource consumption and environmental impact globally. Therefore, this model is of interest not only to businesses, but also to public institutions and citizens, especially local governments, within the framework of sustainable development policies.
- Evaluation / exchange of industrial flow (Waste and by-products, steam, heat, industrial water, etc.).
- Pool of resources and services (Group waste management, logistics, group transportation and purchase, travel planning, etc.)
- Sharing equipment and resources (Means of waste or wastewater treatment / collection, skills, time-sharing work, shared spaces, etc.)
