From laboratory to industrial unit
From idea to realization

IDCO . Innovation Development Company
A Marseille company, was born in 2000 on the basis of a revolutionary and daring idea: to recover sludge from washing quarry aggregates into expanded aggregates by microwaves. It is then a totally innovative application for this technology.
The use of microwave technology in new areas of operation then became IDCO's purpose. Its location in the South of France, near the Calanques natural park and close to Grasse naturally orients it towards plant extraction.

IDCO quickly becomes a MAJOR PLAYER in 4 distinct sectors :

icon-presentation-idco-Plant-Extraction  icon-presentation-idco-Sludge-Recycling.

These activities are at the origin of numerous patents, making it possible to reduce CO2 emissions, energy consumption, to optimize our natural resources and to develop the circular economy…. A real desire for ecological commitment and active participation in the preservation of resources and climate protection!

Today, IDCO designs, develops and markets complete and innovative industrial solutions based on microwave technology allowing high efficiency and homogeneous heating. The range of equipment offered allows batch and continuous processing.

2021 marks a new stage in the scale of our equipment to meet the needs of industry: we are developing high-power equipment and a licensing strategy in partnership with our customers and integrators.

IDCO is supported by

Idco-ademe-ecological-transition.    Idco-bpi-france

IDCO was the winner of the 2nd national competition for the creation of innovative technology companies and won 
1st prize in the EDF Pulse Paca "Industry of the Future" competition 2016

FIRMENICH - Production of essential oils

FIRMENICH's Innovation Natural department has been working with IDCO for several years. Our collaboration is very fruitful and we were able to appreciate the professionalism and great responsiveness of IDCO. This collaboration has led to positive, concrete and promising results that we hope to continue to develop.

R&D industrialisation DirectorPhilippe Pineau


"We have found in IDCO a reliable and competent partner able to feed the research and development innovation process on our themes. The IDCO team was able to understand our specific issues and respond technically to ensure the success of the specifications. It is also a friendly and available team. A subcontractor of choice"
