SCA Hygiene Products runs its own in-house Key 9 esave energy saving program, designed to make full use of the energy efficiency potential on an ongoing basis. As part of this program, SCA Hygiene Products has since 003 carried out more than 6 projects in its German plants with the aim of increasing energy efficiency. The measures focused on continuous process optimisation with the active involvement of all employees. Many measures related to cross-sector technologies such as the compressed air and pump systems and heat generation. All in all, between 003 and 00, the company was thus able to cut the energy usage of its four German plants in Mannheim, Kostheim, Neuss and Witzenhausen by a total of some 0 gigawatt hours per year. Two thirds of the savings were achieved with measures entailing little or zero capital expenditure. Energy efficiency measures. Introduction of company-wide energy management Process optimisation, for example by operating without a pretreatment stage (pulp chest), optimisation of settings, elimination of a plant (refiner) Targeted reduction of energy consumption during shutdowns Introduction of Leak-Seek Day, a routine for the regular identification of plant leaks Use of waste heat from compressed air compressors for heating factory buildings Optimisation of pumping systems Increased efficiency in heat generation by gas burner flame optimisation and carbon monoxide waste gas control Improved insulation of steam lines Key indicators of energy optimisation.

2 Jury evaluation. SCA Hygiene Products is awarded the st prize because the company has implemented many different energy efficiency measures which, taken together, have led to a high absolute level of energy and cost savings. By implementing these measures, the company has shown that, even in energy-intensive sectors, it is possible to achieve continuous improvements in energy efficiency. In addition to the quick wins, involving comparatively low capital expenditure, a very large number of measures were also implemented which will pay back in the long run. In this way the company is demonstrating that when it comes to assessing economic viability, the focus should not be solely on short payback times. Instead, when it s a matter of long-term capital investment, account should also be taken of plant lifecycle costs and the lasting reduction of energy usage and costs. Levels of staff awareness and motivation and staff involvement in the optimisation process are also exemplary. The international Energy Efficiency Award.

5 nd prize: Energy Efficiency Award 0. Südbayerisches Portland-Zementwerk Gebr. Wiesböck & Co. GmbH innovative heat transfer in the cement industry. As part of its Initiative EnergieEffizienz, Deutsche Energie-Agentur GmbH (dena) the German Energy Agency is awarding the nd international Energy Efficiency Award to Südbayerisches Portland-Zementwerk Gebr. Wiesböck & Co. GmbH. The competition is run by dena with support from its premium partners DZ BANK AG, Imtech Deutschland GmbH & Co. KG and Siemens AG and funded by the German Federal Ministry of Economics and Technology. Project description. This Portland cement plant based in southern Bavaria has reduced nitrogen oxide (NO x ) emissions by building an innovative largescale plant which makes use of waste heat from the cooling air from clinker production. Cement clinker is produced in a high temperature process which is associated with high specific energy usage and elevated NO x emissions. Selective catalytic reduction (SCR) greatly reduces the proportion of NO x emissions in the waste gases. In conventional SCR plants, gas burners generally provide the heating of the kiln waste gas, which is necessary for the SCR process when operated in low-dust mode. In March 0, Südbayerisches Portland-Zementwerk commissioned the world s first low-dust SCR plant in the cement industry, which heats the kiln waste gas by making intelligent use of waste heat. A new pendulum grate cooler allows the waste heat from the clinker cooler to be used and a heat exchanger downstream of the catalyst process enables utilisation of the waste gas residual heat. This systematic utilisation of waste heat has resulted in savings of around 0 gigawatt hours of natural gas, since the dedusted waste gas does not have to be heated using gas burners.

6 The international Energy Efficiency Award. Since 007, dena has been rewarding excellence in increasing energy efficiency with the international Energy Efficiency Award. The prizewinning projects demonstrate the economic viability of energy efficiency measures in industry and production. Why not emulate them? Details of all previous winners of the Energy Efficiency Award and further information about efficient energy use can be found, for your company as well, at Jury evaluation. The jury is awarding the nd prize to the Südbayerisches Portland- Zementwerk because this small energy-intensive company decided to push ahead with developing the world s first low-dust SCR plant to reduce nitrogen oxide emissions in the cement industry and with operational testing. Using this innovative denitrification process, heat recovery has made it possible to achieve very high energy savings of 97 percent or 0 gigawatt hours relative to conventional low-dust denitrification. Relative to the total energy usage the plant s clinker production of 900 GWh, this amounts to an energy saving of over two percent. SCR technology had not previously been used in the cement industry because of the high dust content in the waste gas. Process heat accounts for more than 60 percent of the energy used by Germany s industry and production sector. Up until now, the potential for waste heat utilisation had barely been tapped by small and medium-size companies. Südbayerisches Portland-Zementwerk is a perfect example of how waste heat potential can be efficiently exploited. Prize winner profile. Südbayerisches Portland-Zementwerk Gebr. Wiesböck & Co. GmbH is a member of the Rohrdorfer Baustoffgruppe, which employs,00 staff. The 9 employees at Südbayerisches Portland-Zementwerk produce 3,500 tonnes of clinker per day. The prime contractor for the low-dust SCR plant is GEA Bischoff GmbH. This new low-dust SCR technology allows us to manufacture cement clinker as efficiently as possible with the least environmental impact.
