FEATURE: RESIDUES TO RESOURCES Bioenergy International No 82, 6-2015 11 Facts: Scheuch GmbH Founded in 1963 in Ried, Austria as a sheet metal fabrication workshop the familyowned company has evolved into an international business focused on developing and manufacturing air and environmental technologies including extraction, de-dusting and flue gas cleaning within many sectors of industry. The company has around 1 000 employees and a turnover in excess of EUR 127 million. percent cutting its carbon dioxide (CO₂) emissions by about 20 000 tonnes. Important too is that the use of these alternative fuels has absolutely no adverse effect on the cement factory or cement quality. – At present ALFUMA works on the purchase and sale of alternative fuel and alternative raw materials. In the future we will also deal with the preparation of alternative energy carriers, revealed Secklehner adding that the company Facts: Kirchdorfer Industries Founded in 1888 as a cement plant in Kirchdorf, Upper Austria the company is now part of the privately held Kirchdorf Industries, an industry group active in three product lines: cement, raw materials (stone, sand, gravel, ready-mixed concrete), as well as pre-cast concrete components, products and pre-fabricated houses. The group operates worldwide, has approximately 1 400 employees in 13 countries and an annual turnover in excess EUR 200 million. In June 2013, almost exactly 125 years since it started cement production, Kirchdorfer Zementverk produced its 20 millionth tonne of cement. already supplies alternative fuels to other third-party cement plants. Looking ahead In addition to alternative fuels ALFUMA has a range of secondary or recovered raw materials such as iron, aluminium and a silicon carrier that is used for the production of clinker. – The central idea is to use resources as sustainably as possible and to minimise the requirement for primary resources. On the short or medium term ALFUMA shall become the number one address in the field of alternative fuels and alternative raw materials in and around Austria, said Anton Secklehner about ALFUMA’s ambitious goals. For the cement plant the new DeCONOx unit also enables the company to supply more waste heat to the district heat network. – We would like to provide about 4 MW into the network, which is a tripling or even quadrupling of the previous amount, said Secklehner. Furthermore, in combination with the use of alternative fuels, the production quantity and capacity of the cement plant can be optimised as it achieves steadier furnace operation and lower emissions per tonne of cement produced, about 20 percent less compared to a few years ago. – With DeCONOx, existing cement plants and other energy intensive processes can be upgraded with relative ease to make sure that they comply with future legal requirements for NOx reduction. In fact we have developed a mobile pilot plant to offer interested companies the opportunity to trial the process on their own sites and see how it fits in with their operations, ended Alois Hermandinger.
