5The environment and energy are the key issues of tomorrow’s world. The demand for intelligent solutions and innovative technologies in the sectors environmental technology, renewable energy, and energy efficiency is con-tinuously increasing. In Saxony, the environmental and energy technology branch has become an important economic factor.

Saxony’s enterprises assume a leading position primarily in such key mar-kets as, for example, renewable energy, energy storage as well as recycling management. The branch benefits from Saxony’s long tradition as an industrial venue particularly for machine and plant construction. Saxony’s mountains had also been important mining centers for many centuries – during the Mid-dle Ages, silver and other »precious« raw materials were extracted; later, the focus was more on lignite and uranium. This is the foundation for the expert

knowledge and competence found in Saxony’s commercial enterprises and research institutions today which is unrivaled throughout the world; specifi-cally in cleaning up uranium and lignite mining residues, removing hazardous waste, or renovating wastewater systems.

It is in particular Freiberg which has firmly ensconced itself as a leading Euro-pean venue for the development of innovative technologies designed to boost resource and energy efficiency.

2014

The Helmholtz Center Dresden-Rossendorf e. V. (HZDR) coordinates the establishment of Europe’s largest resource network »EIT Raw Materials« on behalf of the European Institute of Innovation & Technology (EIT).

Large silver ore depos-its are discovered in the Erzgebirge Moun-tains. The subsequent great silver rush attracts many people to the region and turns the Erz gebirge Mountains into a densely populat-ed area.

1491

The first discoveries of silver in the Freiberg region start the first silver rush.

1168

The Freiberg senior min-ing administrator Hans Carl von Carlowitz pub-lishes Sylvicultura Oeconomica, the first book on sustainability.

1713

The Bergakademie Freiberg mining acad-emy (today: Freiberg University of Mining and Technology) is established as an edu-cational and training center for miners. The Freiberg University of Mining and Technol-ogy is, thus, the oldest mining institution in the world.

1765

The world’s first high performance pumped storage power plant goes into service in Niederwartha near Dresden.

1929

In the Erzgebirge Mountains, the pumped storage power plant Markersbach goes into operation. With a capacity of 1,050 megawatts, it is one of the largest pow-er stations of its kind in Europe.

1979

The founding of the Wismut GmbH marks the beginning of the decommissioning and rehabilitation measures of the former uranium mining facilities.

1991

Production of solar sili-con wafers is launched by the Bayer Solar GmbH in Freiberg (acquired by the SolarWorld AG Group in 2000).

1994

Construction starts for the world’s largest solar park in Waldpolenz near Leipzig.

2007

The Freiberg Geocom-petence Center (GKZ) is founded.The plant manufac-turer Roth & Rau oberflächentechnik AG (today a member of the Swiss Meyer Burger Group) aligns its cor-porate strategy towards photovoltaics.

2002

Saxony becomes one of 8 model regions within the scope of the German Federal Gov-ernment’s national De-velopment Plan for Electromobility. Since 2012, Saxony has ac-tively participated in the »Showcase Bavaria-Saxony ELECTRIC Mo-BILITy CoNNECTS« project.

The Daimler Group selects Kamenz as the production site for bat-tery systems based on lithium-ion technology and has made consid-erable investments into its subsidiary Deutsche ACCUmotive since 2014.

Power Generation

Solar (PV) With the SolarWorld Industries Sachsen GmbH, SolarWorld covers the entire photovoltaic value creation chain at its production site Freiberg – ranging from the raw material silicon and wafer production to solar cell production all the way to the finished solar module. Here, a total of about 1,500 people work for the SolarWorld AG in three commercial zones. Under the roof of the Solar-World Innovations GmbH, the entire research and development activities of the Group have also been located in Freiberg since 2007.

High performance photovoltaic modules »Made in Germany« form the core business field of the Heckert Solar AG. The company, which was founded in 2001 and is based in Chemnitz, specializes in the production of polycrystal-line solar modules of the most diverse performance classes and dimensions. The current NeMo®P module series was expanded by a 60-cell solar module in early 2014. The high performance PV modules are manufactured complete-ly in Germany, in the highly automated production halls in Chemnitz.

Located in Leipzig, the Solarion AG develops and produces highly efficient and, at the same time, inexpensive thin film solar cells and modules based on copper-indium-gallium-(di)selenide (CIGS). Flexible plastic foil serves as a car-

rier material. Since the modules are very light and unbreakable, they can be easily integrated into building roofs and facades without any expensive sup-porting structures. Solarion manufactures the thin film solar cells according to the roll-to-roll procedure. A patented ion beam assisted process (IBAD) is used for the deposition of the absorber layer. This technology reduces the use of energy and materials and permits a higher degree of efficiency of the solar cells. The first production plant designed for an annual production capacity of 20 megawatts is currently being put into operation.

Solar Thermal Energy

The NARVA Lichtquellen GmbH + Co. KG in Brand-Erbisdorf has been pro-ducing vacuum tubes for solar thermal energy since 2007. NARVA’s certified production includes all essential production stages.The latest product developed by NARVA is its intrinsically safe heat pipe. A characteristic feature of this high performance heat pipe vacuum tube is its valve-free temperature limitation at the appropriate temperature level that is specified by the customer. This limits the peak load and protects the entire system against overheating. The heat pipe is particularly suitable for the supply of process heat and for the use in thermosiphon systems. The vacuum tube’s intrinsic safety substantially reduces the investment and operating costs for the overall system. And it permits, for example, the use of a significantly smaller membrane expansion vessel.

Bottom leftCell production in SolarWorld Industries Sachsen’s clean room

Bottom, 2nd from leftThe current production capacity at Heck-ert Solar amounts to approximately 180 megawatts-peak per year and is continu-ously being expanded.

Bottom, 2nd from rightSolarion’s CIGS solar cells on polymer substrates are particularly flexible, light, and thin. Their average degree of ef-ficiency is more than 10 percent with the record value exceeding 15 percent.

Bottom rightMelting vacuum tubes at NARVA Lichtquellen: The tubes are created in the company’s own glass factory; the prefabrication unit manufactures the req-uisite copper absorber units. Both parts are assembled with a fully automated production line. A patented glass-metal compound between the sheathing and the absorber makes the product robust and durable.

The product portfolio of the GFC AntriebsSysteme GmbH in Coswig includes, for example, slewing gearboxes which are applied in the concentrated solar power (CSP) sector. The extremely compact and backlash-free worm gears are particularly suitable for precise positioning and adjustment tasks. They are needed to track the sun with the mirrors so that the reflected sun rays hit pre-cisely the 5 meter by 5 meter absorber surface which is located up to 1,200 meters away. The highly concentrated sunlight reaches temperatures of up to 1,300 degrees Celsius. This heat is used for power generation with a steam turbine. GFC guarantees that its gearboxes remain lubricated for more than 25 years.

Wind Energy Since January 2009, the Eickhoff Wind Power GmbH has been producing components for gearboxes used in wind energy systems on the outskirts of Dresden. The company is a subsidiary of the Bochum-based Eickhoff Group. Gearwheels, shafts, planet carriers, and other components for wind turbine gearboxes of the EICoGEAR type are produced in large batches at the compa-ny’s state-of-the-art manufacturing and assembly plant in Klipphausen. With this product, the Eickhoff Group has been successful in the wind energy branch for many years now. EICoGEAR gearboxes are built in dimensions ranging between 2.0 megawatts and 3.8 megawatts.

Generators and actuator drives for the wind power branch are delivered by Dresden’s VEM Sachsenwerk GmbH and Zwickau’s VEM motors Thurm GmbH; both are companies of the VEM Group. The manufacturer of medium and large scale machines develops and produces asynchronous and synchro-nous generators for wind turbines with power outputs ranging between 1 megawatt and 8 megawatts. The product spectrum of VEM motors Thurm in Zwickau includes actuator drives for wind turbines for azimuth and pitch gears as well as low voltage machines for hydraulic, oil, or cooling units.

Headquartered in Dresden, the WSB Group is one of the leading providers for planning and implementing renewable energy projects. The company is active both at home and abroad and develops complete solutions for wind farms and photovoltaic parks. The services range from the selection of the right location and wind measurements to construction and commissioning all the way to technical and commercial operational management. Since 1996, WSB has built more than 380 green power plants with a project volume of approxi-mately 1.1 billion euros. one of the largest farm projects that have been real-ized is the Taczalin wind farm in Poland which was officially inaugurated in 2013. With a total output of 45.1 megawatts, the 22 wind turbines generate as much renewable energy as is consumed annually by about 25,000 house-holds.

Dr. Paul Rheinländer »In Eickhoff’s 150 years of company his-

tory, Klipphausen was the first new business location outside of Bochum –

and it has proven to be an excellent choice. We were looking all over Ger-

many for the right location to create additional production capacities in the

wind energy sector. A decisive factor for us were the well-educated, highly

skilled employees we found here in Saxony. And Saxony’s public authorities

undertook every effort to assist us. That’s why we were able to launch mass

production only 18 months after the cornerstone ceremony in early 2009.«

Located in Dresden, the cp.max Rotortechnik GmbH & Co. KG specializes in services revolving around rotor blades for wind turbines. In addition to main-tenance, inspection, and repair, the service portfolio also encompasses the aerodynamic optimization, balancing, and photometric measurement of rotor blades. A specific rope-supported technique, which was developed by the company, in conjunction with mobile personal rope winches grants access to all rotor blade sections – from the blade root to the blade tip.

Geothermal Energy

Systems for the use of near-surface geothermal energy are produced by the Gerodur MPM Kunststoffverarbeitung GmbH & Co. KG in Neustadt, Saxony – a subsidiary of the Swiss HakaGerodur Group. Its GERotherm® geothermal systems are not only suitable for the extraction of geothermal energy (heating/cooling), but also for the discharge (storage) of excess heat into the ground. This requires the use of closed vertical or horizontal geothermal pipe systems and geothermal probes. The requisite distributors and collectors are also part of Gerodur’s product range. The pipe system for heat absorption and/or heat release consists of solid plastic (polyethylene (PE)), which protects it against corrosion, is certified, and has a life cycle of more than 50 years.

11Since its founding in 2007, the Freiberg-based geoENERGIE Konzept GmbH has implemented more than 1,400 geothermal projects. The services provided by the company include the core areas consulting, planning, development, and monitoring of geothermal plants. The portfolio encompasses the comput-er-aided simulation of subsurface conditions, the design of probe fields as well as the implementation of geothermal response tests for the precise dimension-ing of probe fields and well systems. The company also assumes the monitor-ing of geothermal plants during ongoing operations which helps detect incor-rect configurations and identify optimization potentials.

Biomass / Bioenergy

Located in Dresden, the STRABAG Umwelttechnik GmbH is one of the lead-ing enterprises committed to the construction of environmental engineering fa-cilities with a specific focus on waste treatment and biogas plants. In the bio-gas production sector, the company offers two different patented processes which are all in-house developments: Wet fermentation in the LARAN® loop reactor and dry fermentation in the LARAN® plug flow reactor. The wet fer-mentation technology is suitable for reactor sizes of up to 10,000 cubic me-ters, preferably for the cofermentation together with liquid manure or for the fermentation of food residues, sewage sludge, or stillage. Dry fermentation in the fermenter is particularly suitable for the mono fermentation of critical and/or complex structured substrates and for the fermentation of waste with high solid contents as well as fresh and dry manure.

The Dresden-based GICON Bioenergie GmbH, a part of the GICoN Group, develops, plans, and builds biogas plants. The company’s own in-house devel-opment, the GICoN® biogas process, revolves around two-stage, dry-wet fer-mentation with separate hydrolysis. Compared to traditional procedures, it permits a better control of the biogas production while the methane content is 15 percent to 20 percent higher than that of conventional plants. The proce-dure is predominantly applied to the recycling of separately collected or sepa-rate organic waste as well as green waste and agricultural residues. The com-pany possesses comprehensive knowledge and expertise also when it comes to the construction and operation of biogas plants with wet fermentation tech-nology. For research and development activities, GICoN has its own large-scale technical lab.

one of the leading, independent producers and suppliers of biofuels in Ger-many and Europe is the VERBIO Vereinigte BioEnergie AG. The holding’s ad-ministrative premises are located in Leipzig. At three locations, approximately 500 employees produce biodiesel, bioethanol, and biomethane at a large in-dustrial scale. Thanks to the high energy and carbon dioxide efficiency of the facilities, biofuels emit up to 90 percent less carbon dioxide than gasoline or diesel. The company has developed an innovative procedure for biomethane production. With this method, twice as much energy can be generated from one hectare of land than is possible with conventional methods.

Top leftorganic waste fermentation plant in Berlin: The LARAN® plug flow fermenter made by STRABAG Umwelttechnik.When it comes to dry fermentation, the manufacturer provides fermenter sizes of up to 2,600 cubic meters as a standard-ized model series solution.

Top rightBiogas plant made by VERBIo in Zörbig: Without using any food, VERBIo gas is extracted only from such agricultural res-idues as, for example, stillage, a byprod-uct from bioethanol production, as well as straw. This qualifies biomethane as a »fuel of the second generation for natural gas driven vehicles« which is particularly friendly to the environment.

Battery

The family-run enterprise HOPPECKE is the largest manufacturer of industrial battery systems in European ownership. The company has been developing and producing »Made in Germany« since 1927. Thanks to Hoppecke’s cutting edge research and development activities within the branch, its portfolio en-compasses all acknowledged and innovative storage technologies relevant to the branch.An important corporate site is in Zwickau: The HOPPECKE Advanced Battery Technology GmbH. Here, pioneering lithium-ion batteries are produced, and complex energy storage systems are assembled with lead-acid, nickel-cadmi-um, and lithium-ion batteries. The development and production of charging technologies as well as electronic monitoring and control systems are also lo-cated here – vital components to optimize the energy demand and system availability. Since 2011, HoPPECKE Advanced Battery Technology’s core ele-ment has been its new research and development center for innovative energy storage technologies and services.

Located in Zwickau, the GW Batterien GmbH is a spin-off of the GAZ Bat-terie GmbH and Wieser Industrie- und Bahntechnik GmbH corporations. By consolidating its battery business segments, the company has become one of the most important suppliers of battery systems today. In addition to the sup-

ply of lead and nickel cadmium batteries of the most diverse types, another primary focus is on the production, supply, and refreshment of rail vehicle batteries. GW delivers new batteries and complete battery systems, and it also assumes the customized development and new construction of batteries for various applications as well as the maintenance, refreshment, and recondi-tioning of battery systems.

When it comes to high performance batteries for alternative drives, the Daim-ler AG focuses on Saxony. The corporate group is expanding the production capacities for lithium-ion batteries further in its subsidiary Deutsche ACCU-motive GmbH & Co. KG. Systems for the group’s hybrid models and all-elec-tric vehicles are manufactured at the Production Site Kamenz.

The Litarion GmbH, which became a subsidiary of the Canadian battery spe-cialist Electrovaya in April 2015, is Germany’s leading manufacturer of elec-trodes and ceramic separators for lithium-ion battery cells to be applied in mobile and stationary energy storage systems. At its Kamenz factory, Litarion produces these components to meet the corporate group’s own demands as well as the demands of other cell manufacturers.

Friedhelm Nagel »Already since the early 1990s, HoPPECKE has been producing batteries in Zwi-

ckau. The exceptional potential of the location and the employees on site was actually known to us as well as

the specific climate for innovation and the prevailing inventive spirit found here. That’s why we selected this

location and made investments here in order to address the technologies of the future. After the large-scale

demolition of old buildings and the subsequent construction of new ones, HoPPECKE has successfully man-

aged to expand its production site in Zwickau. The new research and development center and the production

facilities for complex energy storage systems went into operation in 2011. With our investments and the public

funding which has encouraged and supported our entrepreneurial commitment, we’re now capable of devel-

oping innovative energy storage solutions, making them economically viable, and transferring them into new

applications.« (Managing Director, HoPPECKE)

Fuel Cells

The Dresden-based sunfire GmbH, which was founded in 2010, develops and produces high temperature electrolysis cells (SoEC) and high temperature fuel cells (SoFC). High temperature fuel cells made by sunfire permit the particu-larly efficient production of electricity and heat according to the combined heat and power principle. Decentralized, combined heat and power in the low power range is considered to be the energy concept of the future because electricity and heat are generated according to the actual demand and right there where they are needed. High temperature electrolysis splits water vapor into hydrogen and oxygen. It is operated with renewable electricity. The re-sultant hydrogen can either be efficiently converted into fuels with sunfire’s power-to-liquids process or directly used in the H2 mobility as well as indus-trial sectors.

The FuelCell Energy Solutions GmbH from Dresden produces the innovative Direct Fuel Cell (DFC®) power plants. These stationary fuel cell power plants generate electric power and utilizable heat in a highly efficient, economically viable manner. The company, which was founded in 2012, is a joint venture of the US American FuelCell Energy Inc. corporation and the research institute Fraunhofer IKTS. DFC® power plants are based on molten carbonate fuel cell technology and are available with capacities ranging between 250 kWel and 2,800 kWel. When it comes to the production of electricity and heat from

Bottom leftAt Litarion, electrodes and separators for high performance lithium-ion batteries are manufactured with cutting edge coat-ing technology. The picture shows the production of coating compounds.

Bottom centerAt FuelCell Energy Solutions: Stacks, the core components of power plants, are stacked on top of one another. DFC® technology operates around the globe in power plants and power plant parks with a nominal capacity of up to 59 mega-watts; so far, this technology has helped generate more than 2.7 terawatt hours of electrical energy.

RightPressure vessel of the RWGS reactor at sunfire’s power-to-liquids demonstration plant Fuel1: RWGS stands for reverse wa-ter-gas shift reaction. This endothermic reaction, which occurs at a temperature of approx. 1,000 degrees Celsius, con-verts Co2 together with H2 into Co and H2o. This permits the reactivation of the Co2 molecule, which is often seen as a »waste problem« and a climate killer, for chemical syntheses. And it upgrades Co2 from a waste product to a raw material.

14 natural gas or biogas, these power plants make use of an electrochemical re-action which emits virtually no pollutants. Since they were specifically devel-oped for decentralized applications, the DFC® power plants are not only suit-able for energy suppliers and sewage companies, but also for industry, com-merce, and public buildings.

Headquartered in Lichtenstein near Zwickau, the AXXELLON GmbH develops and produces high performance lithium batteries for industrial and automotive applications. The product portfolio of the company, which was founded in 2009, ranges from individual electronic components all the way to complete high performance batteries. Specific competences are available in the battery management systems and the associated power electronics sectors. In addition to an innovative vehicle battery, AXXELLoN has also designed and developed a stationary energy storage system for energy coming from photovoltaic plants. With a capacity of 20 kilowatt hours, the storage system is suitable both for isolated and mains parallel operations. It is possible to not only inte-grate the PV plant, but also wind turbines, combined heat and power plants, emergency power generators, and fuel cells into the system.

The Dresden-based eZelleron GmbH, which was founded in 2008, is a Euro-pean leader when it comes to the research and development of portable fuel cell systems for mobile power supplies. The breakthrough came with an inno-vative technology which unites the advantages of conventional (PEM) and

ceramic fuel cells (SoFC). Since the eZelleron fuel cell consists almost entirely of metal, it is lighter, more robust, and cheaper; thus, making it particularly suitable for applications in mobile and portable systems. It is ready to start within just a few seconds (quick-starting ability) and can be operated with conventional lighter gas; in other words, propane and butane, as well as with hydrogen. The patented technology is currently being implemented in several products of diverse performance classes for small and medium sized electrical appliances.

Battery and Network Management

At its production site in Wilsdruff near Dresden, the ads-tec GmbH manufac-tures stationary high performance battery systems and complete storage solu-tions in container formats which are all complete in-house developments. In addition, the medium-sized, family-owned enterprise which is headquartered in Nürtingen near Stuttgart develops and produces IT systems for industrial purposes. The lithium-ion battery storage units StoraXe® come together with an energy management system (EMS). This way, charging and discharging pro-cesses of storage units and energy flows within the network can be controlled and monitored intelligently. And ads-tec’s battery storage solutions are scal-able up to the megawatt hour range which makes them versatile for various applications, for example, when it comes to the intermediate storage of renew-able energy or network services.

Energy and resource efficiency are a decisive competitive factor in every

industrial production. The first »E3-Research Factory« was of-ficially inaugurated at the Chemnitz-based Fraunhofer Institute for Machine Tools and Forming Technology (IWU) in 2014. Here, research is conducted

on solutions for the »Resource-Efficient Production« of tomorrow. on a surface area of more than 1,600 square meters, the Fraun-hofer Society is working on the topics »Powertrain,« »Car Body Construc-tion,« and »Energy Management 2.0« in close partnership with such indus-trial enterprises as, for example, the Volkswagen Group.

Top centerFor a long time now, the eins energie in Sachsen corporation has been research-ing energy topics together with Chemnitz University of Technology. one result of this cooperation is the short-term, large- scale cold storage tank at Chemnitz’s Georgstraße – at the time of its official inauguration in 2007, it was the first above-ground storage tank of its kind in Germany. Today, the tank serves as an example for similar projects around the globe.

Righteins energie sachsen: Inside a cooling system

Located in Großröhrsdorf, the Haase GFK-Technik GmbH produces storage tanks and hot water tanks built with glass fiber reinforced plastics (GRP). The material is resistant to ageing and corrosion and exhibits low thermal conduc-tivity. Thermal energy coming from such energy sources as solar plants, solid fuel boilers, or heat pumps is stored inside the tank and, if so required, used to heat up drinking water or to support the heating system. Water serves as a stor-age medium. Depending on the individual container size, it is, thus, possible to bridge a longer period of time during which no additional energy needs to be fed into the system. The storage tanks, which have a volume of up to 100,000 liters, can be installed both above ground and below ground. Thanks to a spe-cific assembly technique, the tanks can also be mounted in spaces that are dif-ficult to access.

Waste heat is produced in large quantities when processing steel. Excess heat from production is temporarily stored via the local heat network in two underground buffer storage tanks and used for heating the new building and supplying hot water.

Bottom rightNew, innovative products are created by WätaS’ own in-house research and de-velopment department and through the company’s very close cooperation with Saxon universities and other scientific institutions. In 2014, WätaS received the »Innovative through Research« award of the Stifterverband, the German donors’ association for the promotion of sciences and humanities.

The five project partners of the »enerMAT« project – the Fraunhofer EAS IIS Dresden

and four Saxon SMEs – want to drastically simplify the complex design process for energy

management systems which integrate the entire building installations. Their objective is to

use only the amount of energy in buildings which is actually needed – without reducing the

level of comfort. This, in turn, poses entirely new challenges to the level of automation. The

project partners are developing a concept and a software tool for energy-efficient control

systems. The focus is on simulating a holistic model of a building and its technical equipment

which encompasses all operating scenarios. It starts already in the project phase. Thus, it is

possible to already reach sound decisions on investment and operating costs, energy savings,

The Dürr thermea GmbH in ottendorf-okrilla near Dresden has developed the innovative high temperature heat pump thermeco2® which uses carbon di-oxide as a refrigerant. In contrast to conventional fluorinated refrigerants, car-bon dioxide neither contributes to the greenhouse effect nor to ozone deple-tion. For its innovation, the company was presented with the »Refrigeration Award« of the German Federal Ministry for the Environment, Nature Conser-vation, and Nuclear Safety (BMU). Today, Dürr manufactures high temperature heat pumps, liquid chillers, and compressed air dryers with this technology. The systems are applied in building technology as well as industrial processes. For example, the Volkswagen AG Group uses Dürr thermea’s compressed air refrigeration dryers in several factories.

At its production site in Rackwitz near Leipzig, the SES Energiesysteme GmbH manufactures combined heat and power (CHP) plants which are driven by gas engines and provide thermal outputs ranging between 50 kilowatts and 2,000 kilowatts. CHP plants are highly efficient, decentralized energy systems which are operated right where the energy is consumed. The cogeneration

principle revolves around generating electricity and heat at the same time. Using the waste heat emitted during power generation reduces carbon dioxide emissions. SES’s CHP plants are operated with natural gas, biomethane, biogas as well as sewer and landfill gas. The plants are available as ready-to-connect compact modules, in steel or concrete containers, and as turnkey facilities in buildings.

The FASA AG is a medium-sized construction firm headquartered in Chem-nitz. With its ENERGETIKhaus100®, the company has developed a building which is supplied with solar energy and requires neither any oil or gas fired nor any heat pump heating system. 90 percent to 100 percent of the heat de-mand for heating and warm water is covered by solar energy. This is ensured by the intelligent interaction of the solar architecture, the large-scale solar thermal system, and the centralized long-term heat storage as well as a ther-mal insulation with massive, ecological building materials. The rest is done by a stove with a heat exchanger. The innovative building concept was created in cooperation with the Freiberg University of Mining and Technology.

22 The Freiberg University of Mining and Technology sees itself as a modern university of resources which, based on its long tradition in silver mining and metallurgy, has aligned its scientific profiles »Geo«, »Material«, »Energy«, and »Environment« both in research and instruction to meet the challenges of the future. These four core fields impart the university its unique and distinct profile. The spectrum ranges from the exploration of new deposits to the development of alternative energy technologies and materials all the way to the recycling and management of resources. Fundamental and applied research is conducted through intensive cooperations with regionally, nationally, and internationally active companies.

The university’s environmental research is coordinated by the Interdiscipli-nary Ecological Center (IÖZ). The central institution also conducts its own re-search, for example, in the sectors biology, environmental microbiology as well as environmental management. For example, within the scope of the PhytoGerm research project launched by the Federal Ministry of Education and Research (BMBF), the IÖZ investigates how the bioavailability of germani-um and rare earths in soils and their absorption in plants can be used as a ba-sis for phytomining.

Dresden University of Technology is one of Germany’s eleven universities of excellence. one of its five research profiles is »Energy and Environment.«

University of Mining and Technology has developed a procedure which permits the

environmentally friendly and economically profitable joint recycling of vacuum tube and

LCD monitors. Screens of old TV sets contain about 30 percent of lead. Small amounts

of the valuable metals indium and tin are found in LCD monitors. The solution for

recycling lead glass and LCDs excels with its simplicity: With a pyro-

metallurgical method, both devices are melted together in a furnace. This creates mixed

glass, which can be used as glass ceramics, and a plumbiferous phase, which contains all

the metals. This, in turn, permits the subsequent recovery of indium or tin.
