In September 2026, greenValue successfully completed its annual surveillance audit under DIN EN ISO 9001:2015. This year’s practical example was a completed technical due diligence assessment of a biogas plant. The project demonstrated how we combine our extensive experience and technical expertise with certified quality management processes. This approach enables us to reliably identify risks and provide a sound basis for investment decisions.

Technical Expertise and Structured Processes as Key Success Factors

A thorough due diligence assessment requires extensive technical, commercial, and regulatory knowledge, combined with a deep understanding of the operation and development of biogas plants.

The assessment focused on feedstock supply, digestate offtake arrangements, the identification of technical deficiencies and the evaluation of the plant’s future development potential. An analysis of relevant stakeholders provided additional insight into potential risks.

Our quality management system ensures a systematic approach throughout the entire process. This begins with a well-founded cost estimate, providing the client with a high degree of cost certainty. It continues through the structured execution of the due diligence assessment and the timely delivery of results.

The key to success is the combination of industry-specific expertise, practical experience and standardized processes.

Certification Body Recognizes Practical and Effective Quality Management

In its audit report, DEKRA particularly highlighted the systematic maintenance of our legal register and our central document management system. The auditor recognized these as strengths of our internal processes.

The auditor confirmed that our quality management system complies with the requirements of the audited standard and has been effectively maintained.

These tools enable us to assess complex technical and commercial matters transparently. They also allow us to systematically apply lessons learned from completed projects to future assignments.

Quality That Also Convinces Our Clients

greenValue’s commitment to quality delivers results in practice, as confirmed by the positive feedback from our client. Following completion of the due diligence assessment, the client provided an excellent evaluation of both our services and the overall collaboration.

Our due diligence reports provide a sound basis for informed investment decisions. We are particularly pleased when, as in this reference project, our client decides to proceed with an acquisition and successfully secures the project.

The successful surveillance audit reinforces our commitment to the highest quality standards. We support complex renewable energy projects with technical expertise, reliable processes, and transparent, well-documented results.

We sincerely thank the entire greenValue team and the auditor for their professional conduct during the audit!
