Ruf Maschinenbau GmbH & Co.KG
About
RUF Maschinenbau GmbH & Co. KG, headquartered in Zaisertshofen, Bavaria, holds the position of world market leader in hydraulic briquetting presses. Founded in 1969 by Hans Ruf and now led by second-generation owners Roland and Wolfgang Ruf, the company has delivered over 6,000 machines across more than 100 countries from its 13,000 square meter production facility. RUF's briquetting systems compact industrial waste materials into dense, transportable briquettes without any binding agents, spanning three primary material groups: metal chips and swarf (where presses recover up to 97 percent of cutting fluids), wood and biomass residues, and industrial sludges including grinding sludge, hot-rolled sludge, and sewage sludge. The company's grinding sludge presses in the RUF 4 series reduce sludge volumes by more than 50 percent, enabling reclassification as non-hazardous waste in many jurisdictions. Throughput capacities range from 15 to 5,000 kg/h across the portfolio, with hydraulic pressing forces reaching 3,800 kg per square centimeter. RUF also distributes the C.F. Nielsen BP series of mechanical briquetting presses through its Danish subsidiary, offering high-throughput solutions for wood and agricultural residues. In 2021 RUF launched the Formika, a compact mobile briquetting unit designed for direct use at turning and milling machines. The company operates ISO 14001-certified and CO2-neutral production, positioning its technology at the intersection of waste volume reduction, resource recovery, and secondary fuel generation.
