Primobius and Duesenfeld have joined forces to actively advance efficiency and sustainability in lithium-ion battery recycling. Their partnership aims to meet the increasing demand for innovative recycling solutions, particularly in electromobility. Primobius brings extensive experience in developing recycling technologies, plant construction, and process optimization. Duesenfeld contributes expertise in low-temperature vacuum drying and discharging of lithium-ion batteries, focusing on sustainable methods and efficient recovery of valuable materials.

Primobius supports recycling companies, battery manufacturers, and automotive OEMs in operating sustainable recycling plants and overcoming battery recycling challenges. With comprehensive expertise in configuring and building state-of-the-art recycling facilities, Primobius offers tailored solutions to meet the specific needs of its clients. Integrating Duesenfeld's technology enhances Primobius' existing recycling solutions, contributing to flexible, efficient, and environmentally friendly recovery of high-purity materials like cobalt, lithium, nickel, and manganese.

Duesenfeld's process combines mechanical treatment under inert gas atmosphere with vacuum distillation at low temperatures. According to Duesenfeld, this patented process eliminates the specific hazards of flammable electrolytes and prevents the formation of toxic gases. The black mass contains valuable metals, while copper, aluminum, plastic films, heavy materials, and electrolyte solvents are efficiently recovered and reintegrated into supply chains.

Dr. Michel Siemon, CEO of Primobius, states: “By combining our patented solutions with Duesenfeld's advanced technology, we offer our clients a wide range of choices. This allows them to select battery recycling solutions that best fit their operational needs and sustainability goals.”

Till Bußmann, CTO of Duesenfeld, adds: “Our patented processes enable high material recovery, improving the economic efficiency of recycling plants. Through collaboration with Primobius, we can bring this innovative approach to new markets and actively shape the future of sustainable battery recycling.”

Together, Primobius and Duesenfeld offer a flexible and advanced approach to battery recycling, tailored to the evolving needs of the electromobility sector.
