Duesenfeld stands as an innovative force in sustainable battery recycling, specializing in environmentally conscious methods for processing lithium-ion batteries. Based in Germany, the company has developed a unique approach that significantly reduces carbon emissions while maintaining high material recovery rates. Their patented process combines mechanical, thermodynamic, and hydrometallurgical techniques to create an efficient recycling system that supports the growing electric mobility sector.

Since its establishment, Duesenfeld has focused on addressing the environmental challenges associated with battery disposal and resource recovery. The company’s methods have proven particularly effective in recovering valuable materials such as lithium, cobalt, nickel, and graphite, making it an essential contributor to the circular economy of battery materials.

Battery Technology

Duesenfeld’s technology centers on a patented recycling process that begins with deep discharging of batteries, ensuring safe and efficient energy recovery. This initial step powers subsequent recycling operations, reducing overall energy consumption. The process continues with mechanical crushing of batteries into fine particles, followed by material separation and recovery.

What sets Duesenfeld’s technology apart is its low-temperature processing method, which eliminates the need for exhaust gas scrubbing and prevents the formation of toxic hydrogen fluoride. This approach achieves a remarkable 91% recycling rate at the battery cell level, establishing new standards for efficiency in mechanical recycling.

The company’s hydrometallurgical process enables complete removal of fluorides while recovering electrolytes for reuse. This advancement represents a significant improvement over traditional recycling methods, as it prevents hazardous waste formation while maintaining high material recovery rates. The process saves 8.1 tons of CO2 per ton of recycled batteries compared to primary raw material extraction, and 4.8 tons compared to conventional melting processes.

Recent Projects

In 2024, Duesenfeld received the German Sustainability Award for its research and development in environmentally friendly battery recycling processes. The company has also formed a significant partnership with ReElement Technologies, collaborating to supply high-quality LFP black mass for refining into battery-grade products.

Duesenfeld currently operates a demonstration plant with a 3,000-ton annual capacity and has begun expanding its operations through larger-scale facilities. The company actively licenses its technology to recycling companies worldwide, maximizing the environmental benefits of its innovations.
