He was deeply involved in a large segment of inorganic chemistry within SOLVAY who is a major actor (3 billions Euros turn over in inorganic chemicals).
Expertise area covers most of steps of processes with special emphasis on crystallization:
liquid solid crystallizer: mixed crystallizers, swenson type crystallizers and specially OSLO crystallizers:

New process Fluid bed for Percarbonate of sodium (Tavaux and Houston).
New Industrial process : Oslo Crystallizer for salt 5 mm pearls (Bayonne).
Large Crystallizer of monohydrate of sodium for soda ash plant ( Torrelavega and Bernbourg).
Start-up and production of dangerous products in EUROPE and USA(300000T/Year).
New concept of Satellites plants for PCC.

Gas solid crystallizers with fluid bed process:
New process Fluid bed for Percarbonate of sodium (Tavaux and Houston).

Responsible for large environmental procedure covering contact with several government in France, Luxembourg, Germany, and Italy. These procedures were related to disposal of very large waste of calcium chloride coming from large soda ash plant
For years, he was involved in governments agencies and authorities to find acceptable solutions to disposal in river and seas.

He was responsible, initiator and developer of NEUTREC process which treat mainly municipal flue gas from incinerator and flue gas from power plant with bicarbonate and recycle the solid solt resulting of treatment.
The business is now larger than 100 000 t bicarbonate per year.

Carbon dioxide absorption is a frequent step in soda ash industry.
So the expert has a large experience in the field of absorption of CO2 in caustic soda, potassium hydroxide, soda ash solution and ammonia solution.

He was director of new business development at corporate level and responsible for the inorganic part.

One of the main project was the management of a large European project for the treatment of drinking water and waste water with a new product called sodium or potassium ferrate ( Fe6+) in cooperation with 4 universities and 4 chemical companies.

For 15 years he participated in the contact with the pharmaceutical industry to establish the procedures and the quality control.
In particular, he was deeply involved in the new technology of dialysis of the major actors and the move to solid inorganic chemicals and specifically sodium bicarbonate and sodium chloride in solid granular form.

This is a very important business in terms of volume, price, quality and assistance to pharmaceutical customers.

From 2000 to 2007, the stage gate process was the standard methodology used in Solvay's development.

Several very innovative project in mineral chemicals
