The year 1993 witnessed at RUF Maschinenbau the culmination of the exchange mould’s evolution from wood debris to metal chips. Just two years later, as many as ten metal briquetting systems had been sold in addition to the original wood processors. Today, RUF briquetting technology has become an integral constituent in the recycling of chips generated by the metalworking industries. A success story in the SME segment.

Parquet flooring manufacturer Bauwerk briquettes sawings and sanding debris on three RUF installations

The Bauwerk Group’s production plant in Đurđevac, Croatia, runs three RUF presses that transform accumulated sawings and sanding debris into compact wood briquettes. This helps to minimise the huge efforts otherwise involved in handling these bulk materials. In addition, in their briquetted forms, the sawings and sanding debris gain a considerable boost in value as a carbon neutral fuel, which in turn promotes healthy sales revenues.

Precision and efficiency are top priorities for Alcutec GmbH. To this end the aluminium milling specialists have installed a RUF briquetting system which presses the aluminium chips produced during production into compact briquettes. The briquetting process reduces the volume of the chips markedly and in addition clinging cooling lubricant is recovered. The result is that the production waste is much easier to handle and achieves higher prices when sold than loose aluminium chips.

During the production of round bars or rods for flags, skewers and many more products made from wooden planks, lots of wood chips are accumulated. Instead of disposing of them as waste, the wood processor Ortinger presses them into briquettes, which they then sell as fuel. This way they can economically support themselves in another way and their RUF briquetting press has started to pay itself off from the first day on.

The production of aluminium pressing bushes designed for the reliable sealing of pipe unions involves cutting operations that waste nearly 80% of the raw material. As a measure to maximise the yield of this valuable material, the pipe specialist Uponor has been running RUF briquetting systems in its production since 2005. According to WCO Local Coordinator Gerart Oppelt, this investment had paid off after just nine months.

With the introduction of a RUF briquetting press Keiels Formenbau GmbH have simplified their working processes substantially, as well as massively reducing their costs. The briquetting system can press 50 kg per hour of Aluminium chips, which are produced during milling, into solid briquettes. When compared to the sale of loose, wet chips the company has doubled its revenues through selling Aluminium briquettes. In real terms this is a return on investment in about a year.
