Product Recycling
Alternative building material
New for old
Building waste accounts for around 60%
by volume of the total waste produced
in Germany – and the trend points upwards.
This harbours enormous potential
in terms of secondary materials
which it is essential to utilise by channelling
it through today’s recycling industry.
What for others is still in the
future has long been part of our own
everyday work: we, ZECH UMWELT
GmbH, use a wide range of treatment
and cleaning facilities to convert waste
building materials of all kinds into valuable
recycling products. Our “secondhand”
materials have established a “first
class” reputation on the market: they
provide financial benefits and also satisfy
the quality requirements for new materials,
now and in the long term.
Filling and recycled sand
Every grain in A-grade quality:
One question often raised in the remediation
of contaminated sites is what should be
done with the contaminated soil and
demolition debris once it has been excavated.
We provide an alternative to landfill
disposal – with our stationary and
mobile soil remediation technologies,
we process the hazardous material and
turn it into a valuable resource. The recycled
product is suitable for use as wet
or dry filling sand for filling pipe trenches
or as fine levelling material, and can also
be used as a quality-controlled construction
material.
RC ballast
Enabling sustainable building: With our plants we
condition old concrete, old brickwork and old gravel
of the rail traffic so that such building waste can be recycled.
The waste product is used to make high-quality
RC ballast, which can be used as a substrate in
road, rail and path construction, for example, or as a
drainage material. When classified for wet use, the
material is also suitable for tunnel construction. The
product is mainly supplied by our plants in Kriebitzsch
and Coswig.
Drainage materials
A versatile material:: We process broken and classified
building waste and turn it into secondary materials
free of fine particulates. These materials are
mostly used, and with great success, in the fields of
leachate collection and gas drainage. When the material
contains very high percentages of crushed concrete,
it is dimensionally stable and can also be used
for stabilising slopes. When it contains fines, the
porous concrete is gladly used as path material.
Substitute building materials
An eco-friendly and economical alternative: At
our various plants, which are licensed under the Federal
Immission Control Act and certified as a specialised
waste management company, we also recycle
mineral waste. From the waste, we produce inexpensive
substitute building materials, mainly in thermal
processes; these materials are principally used as
landfill construction materials. These are high-quality
products in construction physics terms, offering ecofriendly
alternatives to non-renewable raw materials
such as sand and gravel.
