Taking the lead at the Premnitz site. 105 mm BUND 103,5 mm 102 mm Welcome to EEW Energy from Waste Premnitz. An overview of how EEW Energy from Waste! Built out of responsibility for the region. an EEW plant works. Energy is the basis of our life. As fossil fuels are only available Energy from waste plants are a special kind of high-quality in limited quantities, using energy from waste as a resource is power plant. They not only have to meet the strictest require- becoming increasingly important. As Germany‘s leading compa- ments with regard to emission limits but also to satisfy the ny in the production of environmentally friendly energy from the highest technical demands and are therefore continuously thermal utilisation of waste, it is our task to take the lead. With checked and optimised. For about 30 years, the EEW Energy highly modern energy from waste plants that are state of the from Waste Group has been planning, building and operating art technically and ecologically. With superbly qualifi ed, dedicat- thermal waste recycling plants that set standards throughout ed employees. With good and effective relationships with citi- Europe. New companies are being established and thus new zens, municipalities and companies. And of course with environ- jobs created near to the plants, which are characterised by low mentally friendly energy from waste. emissions, high effi ciency and an exemplary health and safety record. At the same time, consumers and surrounding industri- al companies are benefi ting from the use of the energy gener- ated in an environmentally friendly manner. Vast landscapes, deep forests and calm lakes, these are the hallmarks of the Havelland nature park. Nestling in the middle, on the flats of the lower Havel, lies Premnitz, a town full of energy in both senses of the word. Given this special location, it is particularly important that the energy required in the indus- trial park is produced under environmentally friendly conditions. As is the case with EEW Premnitz, one of the most modern 1 tonne of waste = 600 KWh of power facilities for the recycling of refuse derived fuels (RDF) in ways Power from waste is an important resource. The high that make sense in energy terms. This is specially treated calorifi c value of the material is comparable to that commercial and industrial waste with a significantly higher of brown coal making it virtually predestined for en- calorific value. Every year, 90,000 megawatt hours of power and ergy use. 118,000 megawatt hours of process steam along with 127,000 megawatt hours of district heat are generated with this waste for the neighbouring companies in the industrial and commer- cial park using the two systems (grate firing and fluidized bed firing). In return, up to 270,000 tonnes of RDF are safely recycled every year with low emissions. For local energy and to protect the environment. That is something we are proud of. 2 1 9 1 Every week, several thousand tonnes of waste are transported 5 to the energy from waste plant. 2 4 8 The fuel is collected and placed in interim storage in the was- 2 te bunker which has a capacity of around 9,000 tonnes. A 6 slight underpressure is maintained to ensure that no emissions 1 or odours can escape. Environmental protection starts right 3 there. 7 3 10 The crane driver mixes waste and transfers it continuously to the feed hopper from where it reaches the combustion grate for the combustion line (boiler). In the fluidized bed system, on the other hand, the fuel is blown in.en. 4 As waste self-combusts at the high temperatures in the boiler, no additional fossil fuels are required. Only when the boiler is powered up and powered down are oil burners switched on in order to guarantee the minimum temperature of 850 °C. This 7 9 high temperature is required to ensure that pollutants are Approx. 90,000 megawatt hours of electrical energy and Then the clean gas leaves the 40 m chimney. What remains is largely destroyed. 245,000 megawatt hours of district heat and process steam bottom ash, flue ash and filtration dust. The slag is recovered and are generated in this way every year for the neighbouring indus- used for road-building and landfill.

A benefit for the environment. Energy generation from waste is active environmental protection. Taking the lead With an averageshare of 50% biogenic substances in waste , it is recognised that energy from waste plants produce energy from for the air purity renewable sources pursuant to the Renewable Energies Act (EEG) and thus help to achieve the climate goals in Germany and Eu- requirement. rope. Also exemplary: the emissions of our waste recycling plant easi- ly comply with the strict statutory regulations of the Federal Immissions Control Act (Bundesimmissionsschutzverordnung) and are substantially below them in some cases. This is docu- mented by the seamless emissions control by the supervisory authority. Ideally, come and see for yourself and take a look in person by visiting our plant. You will discover that at EEW Energy from Was- te, we give waste a job in climate protection. 9 Our annual environmental contribution. Power produced in an Up to 270,000 tonnes environmentally friendly manner of recycled waste for 26,000 households 245,000 megawatt hours of 90,000 megawatt hours process steam and district heat of environmentally friendly power produced with energy-saving technology 10 11 We tackle the future. And assume responsibility. More than 145 years – that is how long our expertise has been built on progress. Founded in 1873 as Braunschweigische Kohlen-Berg- werke (BKB), the company was soon also operating as a power generator and has grown steadily to the present day. EEW Energy from Waste entered the waste combustion sector as early as 1990 and today is the most experienced company with the greatest expertise in the environmentally friendly generation of power from thermal waste recycling. As the market leader in Germany, we make a substantial contribution with 18 plants here and in neigh- bouring countries to resource management and to a reduction in greenhouse gas emissions. Our fi gures speak for themselves: Our plants have a yearly energy recycling capacity of around 4.7 million tonnes of waste. This means that we generate approx. 2.4 million megawatt hours of power and 2.6 million megawatt hours of process steam and 900,000 million megawatt hours of district heating.* The power volume produced by EEW alone cor- responds to the electricity requirements of around 700,000 house- holds.** Around 1,150 highly qualifi ed, dedicated employees are sending a clear signal with energy which provides a benefi t not only to numerous companies, but also hundreds of thousands of house- holds and particularly the environment.

Ulti- mately we offer municipalities and companies pioneering waste management that keeps an eye on every aspect: we offer cus- tomised waste disposal concepts, accept the waste and also take care of the statutory documentation procedure. With outstand- ing performance and equal acceptance among the general pop- ulation and local residents. This is how we take the lead. Together. For our future. 15 Rathenow Böhne Mögelin Königshütte B102 Vistra StraßeW olpr Bützer yla Straße Premnitz Bahnhofstraße Döberitz Siedlung Brandenburg Gapel a.d.
