Waste treatment and valorization


Programme (detailed contents):

French and European legal definition of waste. Strategies for wastes elimination (source reduction, valorisation and treatment).  Legal policies.

Air pollution control.

Treatment and valorisation of industrial and urban solids wastes. Energy valorization and material recovery.

Introduction to soil pollution and soil risk assessment. Soil treatment processes.



This training is organised as an active learning. Different activities with a common interest (a specific industrial activity) will allow students to approach various aspects of the waste treatment problem. Specific lectures will be proposed, including conferences of industrial partners.



At the end of this module, the student will have understood and be able to explain:

- the legal and usual definitions of wastes in France. Waste  characterisation

- the strategies  for waste control

- the principles of unit operations and processes commonly used in waste (gas effluent, wastewater and solids waste) reduction, treatment or valorisation (chemical, biochemical and thermal processes).

- the principles of the French methodology for polluted soils risk assessment, the basis of soil treatment processes.


The student will be able to:

- identify basic rules and policies for an environmental problem, and use it to define a technical problem or to propose an adapted solution

- quantify the dispersion of air pollutants from industrial sources

-  determine the valorisation potential for an industrial waste (or gas effluent or wastewater)

- select and design processes for air pollution control and for the treatment or valorisation of industrial water and solid wastes

- understand the risk assessment report of a site

Needed prerequisite

All the basic Chemical Engineering courses
Physical, chemical, biological and mathematical fundamentals
Metrology, environment and risks

Form of assessment

The evaluation of outcome prior learning is made as a continuous training during the semester. According ot the teaching, the assessment will be different: as a written exam, an oral exam, a record, a written report, peers review...
