Description:
ReboTec - recycling of trimmings
" ReboTec is a process, in which slabstock waste and trimmings are comminuted into flakes, then compressed into PU-bonded rectangular or cylindrical blocks that are subsequently cut to size. "
Foam grinding
" Grinding is a recycling process, in which foam trimmings are converted into loose flakes( by our HHRG-22/ 11) .These are then ground into a powder through shear action in a roller mill. Larger particles are filtered and then fed to the mill until all particles fall into the specified < 0.2 mm fines fraction. The regrind powder can then be put in intermediate storage containers ( silos)

The performance data of a crushing system for large-scale industrial useshown on theleft are impressive: upto300 kg flakes are groundinto powder of lessthan0.2 mm grain size everyhour.The on-line metering unit feeds up to 70 kg of powder per minute into the polyol stream. With a second metering unit running in parallel, up to 140 kg of powder per minute can be processed.

rebonding process
" The trimmings are shredded into flakes before being wetted with a polyurethane adhesive, then blended in a mixer and discharged into a mould. Since the loose flakes have a significantly lower bulk density than the finished block, the flakes are compressed inside the mould. Rebonded foam is subsequently formed by adding hot steam and pressure
. "
Broad density range
" The density of the finished blocks ranges between about 80 and 120 kg/ m3. Block densities of up to 500 kg/ m3 are feasible with a suitable flake preselection and special equipment

Advantages:
Production of a new, profitable high-quality product
Environmentally compatible recycling technology
Almost full re-use of all trimmings obtained in slabstock manufacturing
Homogeneous integration of PU flakes into the foam cell structure
