The approach to the case study was mainly qualitative. Information was gathered using a variety of methods to gain a better understanding of the situation, issues, perspectives and priorities. Data collection methods included document/literature review, semi-structured
interviews, checklists and observation. Different types of audits were carried out to achieve various objectives:
- Compliance audit. To check if the current waste management process is being carried out as per the legislation.
- Operational risk audit in combination with pollution prevention audit. To check the
frequency with which an environmental damage occurs and what the consequence
of it is. The measures that have been taken against these possible environmental
damages were verified.
- Resource management audit. To check the optimal utilisation of water,
energy and material resources.
- Occupational risk audit. To verify the measures of occupational safety.
