Research & Development

We conduct research. For your business. And our environment.

We have a clear vision: We want to process and recycle used cells to produce new batteries. Our goal is to achieve zero waste.

We closely collaborate with universities, research institutes and industrial partners. Our extensive research and development activities are conducted with a clear focus on batteries enabling us to noticeably advance and continuously improve technological development in recycling.

Our research activities show clear results.

Successful research:

  • Redux holds numerous patents, including a patent for an X-ray sorting process that helps us achieve a sorting accuracy of up to 99%.
  • With state-of-the-art equipment at our Offenbach site, we can process and recycle roughly 80% of all major types of portable batteries such as alkaline manganese or zinc-carbon batteries.
  • Redux utilizes a self-developed patented process that is continuously improved to disassemble used „mono“ and „baby“ cells and recover secondary raw material for producing new batteries. Thus, we not only preserve primary raw materials but also reduce the amount of waste by roughly 30%.
  • In April 2015, we collaborated with Energizerm one of the world's largest manufacturers of batteries. Together we managed to launch “EcoAdvanced” batteries that were produced by reusing battery components recycled by Redux.
  • Our self-developed sorting process proved particularly efficient and enables us to sort up to 40 batteries per second.
  • A key element of our research activity is maximum protection of the environment. Therefore our plants are certified according to ISO 9001 and ISO 14001. These certifications guarantee highest quality standards.
  • Thanks to our proprietary lithium-ion battery processing method, we are capable of achieving metal recycling rates of 95 percent. The active mass produced by us contains highly concentrated nickel, cobalt, lithium and copper and is produced according to international standards.

Current research projects

22. September 2017


Standing still means falling behind. Therefore, we have already planned our next steps. Redux and Saubermacher want to participate in Crocodile, an EU project. The project focusses on developing an innovative method for extracting cobalt from lithium-ion batteries.
22. September 2017


Another research project named Hydra aims to improve the hydrometallurgical processing of residual materials in waste management. It aims to use synergies from existing treatment processes by, for example, utilizing residual materials such as black mass from alkaline manganese and active material that is extracted from lithium-ion batteries.
