contaminated, and have often been unused for years – is
assuming ever greater significance. This is what we refer
to as land recycling.
Its function is to turn sites previously used and contaminated
by industry into land which can be utilized for new purposes.
BMU's 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 and
services provided by BMU cover the technical, legal and com-
mercial aspects of the works. BMU has for many years been
carrying out complete projects in conjunction with top-rank-
ing consulting engineers.

8. 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 Germany's 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.

10. Treatment Technology
T
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. For
this, Bauer Environment offers compact units on a hire basis
and also builds project-specific turnkey treatment plants. The
related services incorporate detailed planning of all compo-
nents; construction, maintenance and operation, including
monitoring, as well as the necessary emergency-response
backup, for water treatment plants up to 600 l/s.
For the temporary treatment of groundwater and untreated
waste water to remove PHCs, BTEX, PACs, CHCs, heavy
metals and other pollutants, BMU employs tried and tested
techniques such as precipitation, flocculation, filtration,
adsorption, desorption, ion exchange and membrane tech-
nologies. It maintains a large pool of hire equipment for this
purpose.

ide which they enable. Innovative techniques are tested in

bodies 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 world's largest funnel-and-gate
system at a former gasworks in Bavaria. The plant has been
operating without problems ever since.
