"The plants carry out an authorization process related to the environmental compatibility of the deliveries for some specific Aurubis AG purchases for which environmental considerations are important. This applies to waste disposal services, for example. We take a questionnaire about environmental protection and occupational safety topics into account when selecting suppliers and service providers. It is updated regularly and must be completed by all new suppliers. Suppliers that do not complete the questionnaire or that provide insufficient answers are not included in the rest of the tendering process. For existing contracts, the questionnaires and additional documents were assessed for completeness every year to date. In the future, this process will be replaced by the Business Partner Screening and partly automated."
