Quality Assurance: ISO & other Accreditations


Nehlsen believes in quality management, transparency and environmental accountability and hence has begun the path to DIN ISO 9001 and DIN ISO 14001 accreditation, where some operating units are already accredited and others are still undergoing the accreditation process.

The core concepts of these norms are applied throughout all services, where it is not important if the specific Nehlsen operating unit is accredited or not – quality management, transparency and environmental accountability are pillars of our work.

Additionally, Nehlsen has obtained the German certificate for waste handling companies based on the ‘Ordinance on Specialised Waste Management Companies’, a national regulation for waste management companies. In large stages, this regulation is comparable to ISO 9001, and includes, but is not limited to:

  • improved safety through regular audits, supervision and quality control

  • reviews of the company’s internal organisations

    • exact documentation of operational procedures
    • obligations to constantly improve employees’ qualifications (social skills as well as professional skills)
    • extensive insurance policies
    • high standards regarding personal safety equipment (PPE)
    • high standards regarding activities within waste management


In this way, Nehlsen demonstrates its strong commitment to quality management, transparency and environmental accountability not just on the German but also on the international market.

Choices we make when purchasing equipment, recruiting staff or carrying out our services are all influence by these quality and environmental management guidelines, leading to clearly defined and monitored processes.
