With a briquette press, GFC Antriebssysteme GmbH was able to significantly reduce their production costs and design the disposal of grinding sludge and millings in an environmentally friendlier manner. The Saxon specialists for worm gears press almost 30 tonnes of expensive cooling lubricants from sludge and millings annually using a system from RUF, and recycle them. Better waste prices are also the target for the remaining, largely oil-free metal briquettes as would be the case for loose millings. Under the line, the investment will amortise itself in only two years.

A manufacturer of roof systems, Bauder has avoided high transport costs by running RUF briquetting presses. At this Stuttgart company, the dusts generated by cutting and milling operations on rigid polyurethane foam boards are pressed into compact briquettes. A subsequent processor then retrieves the briquettes which it then reuses as a valuable raw material. In bulk form, these dusts would entail high transport costs.
