By focusing on capturing pollutants at the source, Busch’s systems prevent emissions from ever entering the workspace or the atmosphere, making them a favorite for plants prioritizing worker safety alongside environmental compliance.

Busch’s approach centers on their air pollution control system for li battery recycling plant , which uses specialized vacuum pumps and extractors to capture fumes and dust directly at processing points. For example, during battery shredding, their high-volume vacuum arms hover over the shredder, sucking up dust before it can disperse. The captured air is then filtered through a multi-stage system: first, a cyclone separator removes large particles, then a HEPA filter traps fine dust, and finally, a chemical scrubber neutralizes any gases. What’s clever is their use of oil-free vacuum pumps, which eliminate the risk of oil mist contamination—a common issue in traditional vacuum systems that can compromise both air quality and recycled metal purity.

A case in point is their collaboration with a recycling plant in Hamburg that specializes in lithium battery module dismantling. The plant was struggling with dust accumulation on equipment, which not only posed a fire risk but also led to frequent shutdowns for cleaning. Busch installed vacuum extractors at each dismantling station, along with a central filtration system. The result? Dust levels dropped by 95%, equipment downtime decreased by 40%, and worker respiratory complaints vanished. For operators, this shows that pollution control isn’t just about the environment—it’s also about creating a safer, more efficient workplace.
