Big bag and empty sack compactors

The economical solution for empty sacks and big bags

The disposal of large quantities of empty bags and big bags is associated with a high volume of waste and therefore high costs. Our compactors are the solution for efficient, cost-saving and environmentally friendly compaction of empty containers. Our screw compactors visibly reduce the volume of waste. Disposal directly at the point of operation guarantees low-dust and safe sack and big bag handling.

Advantages for your bulk material handling

Standard & individual solutions

Because the requirements of each industry are different.

Sustainable Systems

We attach great importance to a robust and proven design.

Waste and cost reduction

Our compactors compress sacks and big bags at a ratio of 1:20.

Cleanliness in the workplace

The dust-free compaction protects the operating personnel.
