Welcome to pbo! We offer you planning, consulting and organisation in the fields of recycling and waste management.

Sustainable recycling technology for tomorrow’s world
We at pbo – an interdisciplinary team of highly qualified engineers from the fields of process engineering, civil engineering and electrical engineering – have understood that natural resources are finite. As specialists in sustainable recycling technology, we are therefore passionate about putting our know-how at the service of processing, recycling and renewable energies. This is how we protect the environment and climate – and take responsibility for the world of tomorrow.

From the idea to post-commissioning – processing plants from a single source
Whether mechanical or biological treatment: as an independent engineering office, we plan modern waste management plants and implement them for you from A to Z. This means that we accompany you from the initial idea to commissioning and beyond. In doing so, we include all questions of construction technology in our process engineering planning.

pbo – that means a lot of experience, a high degree of flexibility and a cooperative partnership
At pbo, you benefit from short internal channels and a well-coordinated team. This makes us particularly flexible and quick to react. Founded in 1993 by Prof. Dr Thomas Pretz, Dipl.-Ing. Thomas Bergedieck and Dipl.-Ing. Klaus Jörg Onasch, we offer you many years of planning experience, a cooperative partnership – and a service that is just right for you!
