Welcome to arche!

Guiding you safely through the world of chemical regulations

When key experts from the former spin-off company EURAS (EUropean centre for Risk Assessment) of Ghent University  decided that it would be a sin to let their unique know-how and experience go to waste, ARCHE was born. We thus represent over 15 years of experience in environmental/human toxicology, exposure modeling and the preparation of risk assessment dossiers in general.


Assisting you successfully in getting compliant under the current REACH regulation.

Our experience and know-how soon turned out to be quite the asset, and constant expanding was/is needed. Today, our team includes experts from the academic and industrial world, representing a unique and complete overview of our sector. For our offices, our eye quickly fell on the Belgian cities of Ghent and Leuven. We quite enjoy breathing in the vibrant liveliness and creative energy of two of Europe's most renowned university towns. In addition, we are also able to maintain close relations with the academic world, keeping up with the latest developments in our sector and the world of science.
