Operates In


Zentek was founded in 1995 and consists of a number of leading mid-size waste management companies in Germany that operate independently. As a specialist service provider for disposal systems and waste management, we develop and deliver customer and sector-specific solutions for companies. We are a full-service supplier, providing all waste management solutions from a single source – ranging from the initial consultation, to preparing tailored disposal and recycling plans, the timely collection and recovery of all types of waste in keeping with a circular economy through to professional processing and verification. Additionally, Zentek covers all areas of activity specified in the Packaging Act with the Dual System Zentek and takes care of the processes involved in the licensing, collection, sorting, and repossessing of packaging. Thanks to the addition of nine further partners who joined the company in 2019, the Dual System Zentek grew to become an integrated system in the mid-size sector that offers efficient and transparent legally compliant solutions for fulfilling the system participation obligation. With its EPR compliance service, Zentek goes even further to support manufacturers and companies across Europe regarding the extended producer responsibility.
