The best operation for both collecting and disposing of waste and recyclable materials at low cost is to reduce the volume by compacting the material. Depending on the source material, there are different presses that are suitable, even if the basic operation is always the same: The materials filled in are compressed with great pressure until only a fraction of the original volume remains. This produces manageable bales or briquettes that can easily be further processed or even sold.
A well-known process
Anyone who has ever climbed into an overflowing paper garbage can or tried to flatten garden waste such as grass, branches and the like knows that compaction creates more space in the garbage can. With pure physical strength, the effect is limited but still noticeable. With larger amounts of waste, however, it becomes difficult, time-consuming and also dangerous with the purely manual method. In addition, certain types of material can only be permanently compressed with the use of great force.
How to proceed correctly with which material?
Foil and foam, for example, tend to re-expand, and high pressure must be applied to materials such as cans, electrical scrap, drums and the like to make them lose volume. Cardboard and paper are less complicated, but preparation – i.e. tearing up large units – consumes a lot of time that could be used elsewhere. Styrofoam generally can be satisfactorily compacted only by machine operation.
Large tasks, many possibilities
Strautmann offers the right press for every type of material. These include small, reduced models as well as large versions designed for industrial requirements. Regardless of the variant, a press plate or press ram is used for the pressing process in every machine. The material is fed manually or automatically and moves into a pressing chamber where it is compacted. The principle of this operation is always the same, regardless of which materials are processed and in what quantities. Additional functions and machines such as shredders, perforators, dewaters, etc. expand the possibilities of the presses and thus optimally adapt the operation to the material.
