PAPER NEWS - BIBKO

Dear customer, dear business partner,
Due to the financial and economic crises, 2009 was a difficult year. With the slogan “Mutually, we show
strength in the crisis” we fortunately managed to withstand the national and international crisis. We have
believed in our success and lived our visions. Hence, commonly we have mastered the last year in spite of
the worldwide difficulties.
The attached BIBKO® Paper News gives an overview about our successful activities this year. It shows
projects we have commissioned and gives information about international shows we have attended.
Without a doubt the “Bauma” show in Munich will be one of the highlights in 2010. This is the largest
construction show worldwide and we will again display our product line. We are looking forward to see you
at our booth 906A/1 at the open-air exhibition ground F9.
We would like to thank you for your trust in 2009 and wish you all the best and a successful year 2010.

Shows Shows 2010
SibStroyExpo 2009 – Novosibirsk (Russia)
SibStroyExpo – the largest exhibition in Siberia
Beginning on the 29th of September construction
equipment and extraordinary technology from international
manufacturers was displayed until the 2nd of
October in Novosibirsk (Russia).
Goal of the show was to exchange information among
experts and to intensify contacts to our customers and
business partners.
As the attendance
of the show was
very good a lot of
potential customers
have been informed
about the subject
“Recycling of
leftover readymix
and washwater with
the BIBKO ® equipment”. With its expertise and competence
the BIBKO ® staff has given valuable information.
The result of the show indicates that BIBKO ® is one of the
most successful manufacturers of recycling systems in
this business area.
BIBKO ® GmbH develops recyclingand
handling concept for precast plant
VALCKE PREFAB BETON in Vlamertinge, Belgium
invests in new recycling- and handling system for
leftover concrete.
Since 1960 VALCKE manufactures different precast
elements. Besides pre-stressed beams, wall elements
of various shapes, colours and designs are part of the
product line.
The entire production facility of the company is
spread out on an area of 25 ha. As a result washwater
as well as leftover concrete is generated at different
locations throughout the plant. Currently both
washwater and leftover concrete is led and collected
locally in settling pits. An in-house excavator empties
these settling pits on a regular basis and loads the
material on a truck. At a designated area the material
is discharged. Due to the cementitious fines the material
is hardening.
Concrete Show 2009 (Brazil)
„Concrete Show 2009“ in Brazil took place from 26th
of August until 28th of August 2009 in Sao Paulo. This
show is considered the most important show of the concrete
and construction industry in South America. Machinery
as well as tools, plant and technical equipment
was displayed there.
In 2009 the “Concrete show” had 17.145 attendees.
Compared to 2008 this is a plus of 23,5%. Hence, the
show was a great success
for BIBKO ® .
In conjunction with our
Brazilian representatives,
BIBKO ® displayed
the proven BIBKO ® systems
to recycle leftover readymix and washwater in the
readymix and precast industry.

Engineering Projects
After a certain time a crusher is needed to break the
material and transport it off side. Washwater is
collected in a settling pond. As the fines settle to
the groud the volume of the pond decreases continuously.
Since this solution involves extensive costs to hold
and maintain the storage area transport the crushed
material as well as the operational costs of the crusher
BIBKO ® has been contacted to work out a new
recycling concept for the plant.
Recycling concept
Due to the large distances between the different locations
where washwater and leftover concrete is generated,
in conjunction with the customer it was agreed
to keep the internal transport system as it is. However,
goal of the BIBKO ® -recycling concept was that the
large storage area as well as the function of the settling
pond is no longer needed. Another goal of the
concept was to simplify the handling of the residual
material.

Recycling solution
Especially to address the request for easier handling
of the residual material, it was agreed to install the
BIBKO ® -recycling system in the ground. This allows
the truck to easy access the discharge point of the
material. By lifting its loading platform the material
slides straight into the recycling system.
The recycling process takes place in 4
stages
Stage 1 – Material charge
The material charge takes place from top through a driveover
grid. The material is collected in a 10 m long
buffer with a buffer volume of 10 m³. The length of 10 m
has been chosen, to give sufficient buffer volume.
Within the dosing buffer the material is moved to the side
where the recycling system type ComTec is located.
A bucket row takes the material and dicharges it onto a
screw conveyor. This conveyor moves the material continuously
into the recycling system.
Stage 2 – Recycling system type ComTec
Within the recycling system the fines < 0,2 mm
(cement, fine sand) are washed out. Together with the
residual water they are collected in the pump sump
attached to the recycling system. From there the water-fine-mixture
is pumped to an agitator tank.
Material with a size > 0,2 mm is taken by a bucket
row and discharged onto a screw conveyor. The conveyor
moves the material into a material box.
Stage 3 – Agitatior tank
In the above ground agitator tank made of steel the
water-fine-mixture of the recycling system is buffered.
An agitator prevents the fines from settling to the
ground.
Layout
Engineering Projects
Stage 4 – Water treatment
Goal of the process is to get cleared water. Hence,
the water buffered in the agitator tank is fed into a
chamber filter press. The removed fines are compacted
to a filter cake and disposed. The cleared water
is collected in the former settling pond. Unlike before
the pond only holds the water but is no longer used
as a settling pond.
Conclusion
With the decision to go for a BIBKO ® -recycling concept
VALCKE PREFAB has made a trend-setting decision.
In the future residual material will be recycled
and could be reused in the batch process. Costs to
crush hardened material as well as the costs to transport
the material off site do no longer occur. In addition
there is the possibility to reuse the cleared water
which is buffered in the pond in the batch process,
too.
Therefore, the reuse of the reclaimed material saves
money and makes the purchase of a BIBKO ® recyc -
ling system a profitable investment.
Ecological benefit
Besides the economical savings there are other
aspects involved in the concept of reusing the reclaimed
material.
■ Due to the material loop when using a BIBKO ® -
recycling system natural ressources are preserved
■ CO2-Emissions from mining minerals do not occur
at all.
Besides the economic benefit the use of a BIBKO ® -
recycling system is an active contribution to protect
the environment and to preserve natural ressouces.

Residual concrete recycling system
for Warbud Beton Sp. z o.o.
CONCRETE TECHNOLOGY
The fourth ComTec residual concrete recycling system has been installed together with a dosing buffer at the Polish company Warbud Beton
Sp. z o.o., a long-standing and satisfied customer of the German company Bibko Umwelttechnik & Beratung GmbH from Beilstein.
A powerful dosing buffer has been placed
upstream of the ComTec 30 wash-out
machine. This has the advantage that the
vehicles can empty the residual concrete
intermittently. The dosing buffer consists of
a 5 m long trough that can accept approx.
6 m3 of residual concrete in a short space
of time. As a result, there are no waiting
times like those that occur in systems without
a dosing buffer. The 6 m wide charging
hopper of the dosing buffer offers enough
space to be able to wash out 3 vehicles at
the same time and to discharge the residual
concrete.
The residual concrete and the washing
water are initially all buffered intermediately
in the dosing buffer. The residual con -
crete is transported in the direction of the
built-in bucket conveyor via a cylindrical
screw conveyor in a semi-circular trough.

At home:
Closed buckets lift the material up and de -
posit it in the washout machine.
Water and residual concrete are discharged
into the washout machine in a defined
manner via the bucket conveyor. The wash -
ing quality, the separation cut and, hence,
the density in the residual water tank are
thus independent of the emptying speed of
the plant user.
An above-ground steel tank equipped with
three agitators was selected for the accumulating
residual water. The residual water
from the Bibko recycling machine is transported
to the residual water tank via a
pump sump. The built-in agitators keep the
fines < 0.2 mm in the residual water in suspension.
Settling of the fines is thus pre -
vented. The residual water is used in the
mixing process and for washing out the
vehicles.

Bibko is one of the leading suppliers in this
field with more than 1,250 recycling
systems in use worldwide. The Bibko system
offers a recycling capacity of 20 m3 /h and
is fully equipped with a corresponding recycling
water treatment facility. As in the case
of stationary plants, solids of > 0.2 mm are
washed out accordingly. The water containing
fine particles < 0.2 mm is fed to a parallel
recycling water reservoir. The fine particles
are kept in suspension here by means
of cyclic stirring. The fine particles and the
residual water are fed back to the mixing
process.
The main feature of the mobile version is
that the entire plant with the corresponding
steel bath is installed on a frame construc -
tion. Elaborate on-site building measures for
reservoirs and installations provided by the
factory are hence dispensed with. The plant
was manufactured ready for connection in
the Bibko factory and all parts of the plant
were hot-dip galvanised. Only the electrical
and water connections needed to be made
on site.
The plant was delivered with an appro -
priate winter package in order to cope with
the enormous temperature fluctuations in
Russia. The plant’s features include the following
technical details (fig. 1):
1 Lateral cladding of the bath with
sandwich panels
2 Heating unit on the screw conveyor
plus additional insulation and heating
3 Two lateral heating units
4 Cover for the hopper aperture (in the
machine)
5 Cladding and insulation of the pump
sump
6 Lateral cladding of the trough made of
galvanised steel panels, insulated with
sandwich panels
