The so-called Seveso Directive was adopted in the wake of the emotional outcry following the accidental discharge of dioxin in 1976 in the municipality of Seveso, Italy. At the time, the European States adopted a common policy with regard to the prevention of major industrial risks. On June 24, 1982, the so-called Seveso Directive required that States and companies identify the risks associated with certain dangerous industrial activities and take the necessary measures to ensure protection. The Seveso Directive has been modified several times and its scope gradually extended, in particular following an accident in Basel, Switzerland, in 1986.

There are various types of sludge depending on its origin:
- Primary sludge comes, for example, from digester settling tanks at wastewater treatment plants. It is both rich in mineral matter (micro-sand, soil, etc.) and contains organic matter;
- Biological sludge is also referred to as secondary sludge, and comes from biological treatment processes;
- Physical-chemical sludge is a variant of the above types and results from the addition of reagents (iron or aluminum salts) to bind together the fine particles in wastewater.
Depending on its quality and composition, the sludge is disposed of in one of four ways: land application, landfilling, incineration or composting.

Sustainable development is based on three criteria: environmental protection, social progress and economic development. Production and consumption methods must respect the human and natural environment to enable all the earth’s inhabitants to satisfy their basic needs (food, shelter, clothing, education, work, and live in a healthy environment).

A change in behavior by everyone (citizens, companies, local and regional authorities, governments and international institutions) to counter the threats looming over our planet (social inequality, industrial and health risks, climate change, loss of biodiversity, and so on).
