Quality management

The ISO 9000 family addresses various aspects of quality management and contains some of ISO’s best known standards. The standards provide guidance and tools for companies and organizations who want to ensure that their products and services consistently meet customer’s requirements, and that quality is consistently improved.

ISO 9001

ISO 9001:2015 sets out the criteria for a quality management system and is the only standard in the family that can be certified to (although this is not a requirement).

This standard is based on a number of quality management principles including a strong customer focus, the motivation and implication of top management, the process approach and continual improvement.

Using ISO 9001:2015 helps ensure that customers get consistent, good quality products and services, which in turn brings many business benefits.

The ISO 9001 certificate was awarded for the first time on 21 August 2006 and is valid until 15 October 2026.

Environmental management

The ISO 14000 family of standards provides practical tools for companies and organizations of all kinds looking to manage their environmental responsibilities.

ISO 14001

ISO 14001:2015 and its supporting standards such as ISO 14006:2011 focus on environmental systems to achieve this. The other standards in the family focus on specific approaches such as audits, communications, labelling and life cycle analysis, as well as environmental challenges such as climate change.

The ISO 14001 certificate was awarded for the first time on 10 October 2011 and is valid until 15 October 2026.

Cradle to Cradle certification - Water and Soil Stewardship

In our environmental action plan and through our Cradle to Cradle certification part Water and Soil Stewardship, we continue to work on good management of our water resources.

Own water treatment process in our paint division

Our annual water intake in 2023 was 1,255 m³. Most of this is for sanitary and domestic use (651 m³) and is treated in the public water treatment plant in Deinze.
A small part (16 m³) we process in our products when making gypsum. The remainder (588 m³) is water used in the coating process in our paint division for the pre-treatment baths, rinsing, cleaning out and part demi-water. We have our own water treatment installation which allows us to use this water in a long cycle. About once a year, the water is refreshed and the effluents and water from the pre-treatment baths are collected and processed by an authorised processor.

Environmental action plan

Within our environmental action plan, we continue to work towards continuous improvement of our processes.
