As a way to which BMUs know-how in the application of Bauer specialiststem the tide of increasing land use, the restoration of former foundation engineering techniques, in emissions control andindustrial, commercial or military sites – most of which are in health and safety matters is key.contaminated, and have often been unused for years – isassuming ever greater significance. This is what we referto as land recycling.Its function is to turn sites previously used and contaminatedby industry into land which can be utilized for new purposes.BMUs role lies in demolition and clearance, producing exca-vation pits, carrying out earthworks, protecting or decontami-nating water and soil, development and recultivation, depend-ing on the intended new usage of the land. The products andservices provided by BMU cover the technical, legal and com-mercial aspects of the works. BMU has for many years beencarrying out complete projects in conjunction with top-rank-ing consulting engineers. 6 BAUER UMWELT
    • Dismantling of Industrial Infrastructure T he demolition and clearance of industrial and commer- cial facilities imposes high demands on the contractor because of the wide variety of individual tasks involved and the essential need to comply with all quality and safety standards. Bauer Environment meets those demands based on the deployment of its own dedicated machinery and equip- ment, its experienced, highly trained staff, meticulous depth of planning, and the implementation of all required health and safety and environmental measures to the highest standards. Bauer Environment specializes in the demolition and clear- ance of industrial facilities so as to enable new usage, often entailing decontamination of buildings and machinery and cul- minating in remediation of the ground. This may include dem- olition of chimneys using specialist equipment or by blasting, as well as the targeted removal from buildings of contamina- tion by asbestos, heavy metals and PACs. Our experience enables us to offer efficient, cost-effective and compliant methods of recycling and disposing of residual materials and waste. We undertake the dismantling of steel structures – such as the Schnettker motorway bridge near Dortmund – and the selective clearance of tank farms and pipeline facilities in accordance with the given requirements and where appropri- ate in conjunction with the other BAUER Group units special- izing in structural steel engineering and building renovation. Bauer Environment operates a quality management system conforming to the KTA 1401 standard of Germanys Nuclear Safety Standards Commission. In recent years the company has carried out a number of demolition and ground remedia- tion projects at nuclear facilities. Bauer Environment offers a broad range of products and services allied to expertise in handling large, complex projects. All its work is guided by considerations of cost-effectiveness, while adhering to the highest health, safety and environmental standards. 8 BAUER UMWELT
    • Treatment TechnologyT he widely varying pollution of groundwater or of untreat- ed waste water from groundwater control and construc- tion engineering works demands the application of tech-nically and commercially optimized treatment methods. Forthis, Bauer Environment offers compact units on a hire basisand also builds project-specific turnkey treatment plants. Therelated services incorporate detailed planning of all compo-nents; construction, maintenance and operation, includingmonitoring, as well as the necessary emergency-responsebackup, for water treatment plants up to 600 l/s.For the temporary treatment of groundwater and untreatedwaste water to remove PHCs, BTEX, PACs, CHCs, heavymetals and other pollutants, BMU employs tried and testedtechniques such as precipitation, flocculation, filtration,adsorption, desorption, ion exchange and membrane tech-nologies. It maintains a large pool of hire equipment for thispurpose. For remediation of the unsaturated soil zone, soil vapourAnother area of focus is the application of biological and nat- extraction units are deployed, in some cases in combinationural treatment methods.

Innovative techniques are tested inresearch partnerships with universities and other scientific In-situ techniques are deployed in isolation or supplementingbodies and subsequently brought to market. pump-and-treat processes, and soil vapour techniques are used to cut down the time needed for remediation. Using thermally assisted methods such as thermo-stripping, hot- steam injection and hot-water flushing, the company has on a number of occasions achieved lasting remediation success within just a few weeks or months. Bauer Environment is a pioneer in the application of reactive walls, funnel-and-gate and drain-and-gate systems, and in- situ biosorption reactors. As well as deploying the first reac- tive wall and the first sorption reactor in Germany, in 2005 the company installed the worlds largest funnel-and-gate system at a former gasworks in Bavaria. The plant has been operating without problems ever since. 10 BAUER UMWELT
