Green Compass

Derwen were one of the ten pathfinder companies in the pioneering of this publicly available specification (PAS) for performance. The PAS 402 was sponsored by Constructing Excellence in Wales and its development facilitated by the British Standards Institution (BSI) in consultation with waste industry stakeholders.

The PAS is focused on the performance of the waste management company and aims to provide the customer with assurance that their waste is being handled in an environmentally sound and legal manner. Derwen was one of the first companies to achieve accreditation in June 2009, and annual audits are conducted to ensure compliance.
