How can the imbalances between the human need for natural resources and their availability be addressed?
Global growth in recent decades has been developing rapidly. This development creates strong imbalances between the human need for natural resources and their availability. The use of secondary raw materials as a substitute for natural materials is therefore becoming a major necessity and challenge for the industrial, political and scientific worlds. Reusing these secondary raw materials in different fields of application requires the control of several parameters of primary importance such as economic, environmental technical and sustainability factors.
To address these issues, IMT expertise deals with the transformation and new uses of resources along the entire value chain, for example issues of:
- understanding and controlling the interaction of these new resources (secondary raw materials) with their host environments,
- consideration of environmental, biological, geotechnical, mechanical and economic parameters
- designing eco-materials, recycling and reuse processes, industries and works of the future based on secondary raw materials
- development of value chains
Our success stories
“Handbook on characterization of biomass, biowaste and related by-products” written by Ange NZIHOU.
This book provides authoritative information, techniques and data necessary for the appropriate understanding of biomass and biowaste (understood as contaminated biomass) composition and behaviour while processed in various conditions and technologies.
Flash treatment unit, SEDICIM Project: Installation and commissioning of the flash calcination furnace for sediment valorisation
In education too, we are thinking about renewable energy and sustainable development with a project in the Eco-design, Materials and Processes department (ECOMAP) based on the manufacture of boat wind turbine blades made from bio-sourced materials.

- SEDIMATERIALS: Program and national approach launched in 2009. This is a technical methodology for the use of sediments in the construction materials sector to fully support the interested stakeholders (institutions, managers, companies, etc.,) in this approach. Below is an example of two ambitious projects in progress:
- SEDICIM project: Project for the use of sediments in the cement industry. Studies conducted by IMT and EQIOM and their partners demonstrate the technical, economic and environmental feasibility of using sediments. The project is also part of the ECOSED Chair created by IMTLD.
- SEDIASPHALT project: Project for the use of sediments in bituminous materials. The objective is therefore to substitute quarried aggregates with dredged sediments to produce different grades of asphalt.
- ECOSED Digital 4.0 Chair: Circular ECOnomy of SEDiments (IMT Lille Douai)
This Chair aims at promoting scientific and technological work and partnerships in the management of port and river sediments in order to develop relevant recovery methods in various applications such as civil engineering works and products (such as roads, concrete, binders, landscape mounds, embankments, artificial aggregates to consolidate beaches, etc.)
- ECOCIRNOV Chair (IMT Lille Douai/Armines)
The objective is to increase the rate of recycling of household or industrial waste and, on the other hand, to achieve greater added value in the use of certain by-products that have already been recovered.
- VALTHERA – Reuse of residues and by-products of biomass processing
- PREVER – Energy recovery from residues
- Platform for the analysis of air pollutants: analysis of metals (ICP-AES, ICP-MS, HR-ICP-MS), organic compounds (TD-GC-MS, UPLC-TOF-MS), nanoparticle counter, portable carbon-soot analyzer (personal exposure)
- Platform for the development and characterization of micro-sensors, printed electronics
- MARVAPOL : Advanced Materials Recycled by VaPothermOLysis (IMT Mines Albi)
- Transfer in Complex Fluids Laboratory (TFC): advanced optical metrology (stero-microPIV, PIV, LDA, PLIF, Ultra Fast Camera, optical microscopy) (IMT Lille Douai)
