pictogramme radis


a group of pioneers with a passion for the land, aware of the need to protect the soil and biodiversity, started the organic farming movement.  No organic specifications existed at the time. Everything had to be put in place! These organic pioneers helped draft European regulations and national private specifications.

The European Organic Regulation was established. Blaise Hommelen created the company ‘ECOCERT BELGIUM’ to take up the challenge of reliable and credible audits and certification of organic agriculture and to enable businesses to get the best out of their products.

ECOCERT BELGIUM expanded its auditing and certification activities internationally. That same year, the private Ecogarantie® specification was created to certify cosmetics and cleaning products not covered by the European organic regulation.
