ISO 14001 (developed by the International Organization for Standardization) applies to sustainable development and specifies the requirements for an environmental management system (continual improvement and specific requirements).
The ISO 22000 certification guarantees our control of food safety hazards: this international standard aims to harmonise requirements in the area of food safety management among all players in the agri-food industry. It integrates the principles of Hazard Analysis and Critical Points Control (HACCP).
OHSAS 18001 indicates how to implement an occupational health and safety management system. It aims to help organisations achieve better risk management in order to reduce workplace accidents, improve performance in terms of occupational health and safety, and comply with legislation.
This standard defines the criteria for a quality management system, which include in particular a strong client focus, the continual improvement of the services on offer, and the motivation and implication of top management.
