The traditional structure of our economy is based on a linear model: “extract—produce—consume—dispose.” This model has reached its limits, resulting in unsustainable pressure on the planet’s resources. It is essential to mitigate the environmental impact of our economy and to embrace a circular economy approach, grounded in the principles of the 3 Rs: “reduce—reuse—recycle.” This model extends beyond merely converting waste into raw materials or reusing wastewater; it also presents an opportunity to significantly lower greenhouse gas emissions from industrial and artisanal processes, which release various pollutants such as nitrogen oxides, sulfur oxides, fine particles, and volatile organic compounds (VOCs). Emissions can stem directly from fossil fuel combustion or be associated with fine dust released from industries like cement, gravel, and quarries. Increased recycling can help reduce these emissions. The circular economy catalyzes ecological transformation while supporting the development of regions and agricultural areas. Industrialists, economic stakeholders, farmers, and public authorities engage in reciprocal agreements, which foster significant progress in both environmental protection and economic development. The circular economy is now recognized as a national objective and a cornerstone of sustainable development in many developed countries.
