We follow the ISO 9001 and ISO 14001 standards. The ISO 9001 standard provides guidelines on the quality system and the way the organisation uses that quality policy. In addition, the standard provides guidelines in order to ensure and improve processes that are important for increasing customer satisfaction. Companies that meet the ISO 9001 and ISO 14001 standards have a better understanding and better control of business processes and their environmental impact. This leads to focused and continuous improvement with the ultimate aim of ensuring a high level of customer satisfaction and to minimise the environmental load.
