Product
Product description
Gypsum based plasters are primarily made of stucco
(calcium sulphate hemihydrate). The other raw
materials used are calcite, expanded perlite, lime,
cellulose, retarders, starch, air-entrainers, polymer and
plasticizers.
Manufacturing starts with the stucco preparation
(grinding, calcination and separation), followed by
expanded perlite and calcite preparation for
production. After receive of the gypsum mineral
(CaSO4.2H2O) to the Dalsan’s plant, it is grinded and
heated to remove 75% of combined water, resulting in
the formation of stucco (calcium sulphate hemihydrate)
(CaSO4.½H2O). It is separated depending on the size
of powder and is then transferred to the silos for
storage. After that, dry powder is mixed with the other
raw materials. Finally, the final products are packaged
for delivery.
Dalsan manufactures various gypsum based
construction and industrial plasters to required
specifications for different applications. Reference
standards applied are TS EN 13279-1 and TS EN
13279-2. ADERTEK, KARTEK, DERZTEK are
packaged in polypropylene laminated bags with an
average weight of 30 kg, ALÇITEK and SIVATEK with
35kg. SATENTEK is available in both Kraft bags of
15kg and polypropylene laminated bags of 30 Kg.The
main products that are part of this study are: ALÇITEK
(Projection Gypsum Plaster), SIVATEK (Manual
2
Plaster with Perlite), SATENTEK (Finishing Plaster),
KARTEK (Cornice Plaster), CERACAST (Industrial
Plaster), DERZTEK (Jointing Compound) and finally
ADERDEK (Bonding Plaster).
Application
Applications of gypsum based plasters covered under
this EPD are shown below:
ALÇITEK: It is gypsum-based, ready-to-use spray
plaster. It can be directly applied on brick, concrete,
aerated-concrete, etc.
SIVATEK: It is gypsum based specially formulated
ready-to-use bagged plaster that can be applied on
directly brick, concrete, aerated-concrete, etc.
SATENTEK: With its high adherence, this finishing
plaster is used as an undercoat for all types of
paintings. SATENTEK can be applied on SIVATEK
and COREX plasterboard surface.
KARTEK: It is used for the production of decorative
elements like cornices.
CERACAST: It is used in the moulds of sanitary ware
and bricks moulds in those industries.
DERZTEK: It is used at COREX plasterboard joints
over joint tapes.
ADERTEK: It is used for bonding COREX
plasterboard, EPS (expanded polystyrene), XPS
(extruded polystyrene), mineral wools (glass wool, rock
wool) and composite insulation panels over surfaces
like brick, concrete, aerated-concrete etc.

Base materials / Ancillary materials
Gypsum based mineral plasters are made of raw
materials such as stucco (calcium sulphate
hemihydrate), calcite, expanded perlite, lime, cellulose,
retarders, starch, air entraining agents, polymer and
plasticizer.
There are no products that can be included in
“Candidate List of Substances of Very High Concern
for Authorisation”. However, there are some chemicals
Gypsum based plasters have a long life and can be
recycled or disposed of designated landfill sites at the
end of their useful life.
GREENGUARD Certification
Some of the products covered by this EPD have also
been awarded GREENGUARD certification. It is
awarded to products that protect human health and
quality of life by improving indoor air quality and
reducing chemical exposure when they are in use. The
GREENGUARD Environmental Institute (GEI) has
awarded GREENGUARD Indoor Air Quality
Certification® and GREENGUARD Children &
SchoolsSM Certification to the following gypsum based
mineral plasters: ALÇITEK, SIVATEK and SATENTEK.
Reference service life
This EPD is relevant to cradle to factory gate as well
as disposal of product after use. Therefore no
reference to useful life is required.

System boundary
This is a cradle to gate EPD including disposal of
product after use. System boundary for the Life Cycle
Assessment involves raw materials (A1), transport (A2)
manufacturing (A3) and disposal (C4).
‘Raw materials stage’ includes extraction and
processing raw materials. ‘Manufacturing stage’ starts
with further processing some raw materials needed for
the production, mixing all raw materials and packaging
the final product. ‘Transport stage’ is only relevant for
delivery of all raw materials to the plant and forklift
usage within the factory.
Concerning the end of life, all gypsum based plasters
end up at landfill as their final fate. The benefit from
recycling and reuse is not relevant for this LCA work.
In addition, all waste coming from the production
processes and service areas is managed in
accordance with valid legal requirements. There is no
wastewater from the process.However, there is
wastewater arising from general use within the factory,
which is very small and treated in two biological
wastewater treatment plants. The treated water is used
in irrigation of gardens.

Cut-off criteria
Where there are no data available, raw materials that
are a minor constituent of the product amounting less
than 1% of total raw materials are excluded in this
study.
Comparability
Basically, a comparison or an evaluation of EPD data
is only possible if all the data sets to be compared
were created according to EN 15804 and the building
context, respectively the product-specific
characteristics of performance, are taken into account.
This EPD is comparable with gypsum based plasters
that comply with the PCR document Part B: Mineral
factory-made mortar and are evaluated according to
EN 15804 norms.

LCA: Scenarios and additional technical information
The impact indicators were performed according to
LCA standard (ISO 14040/44) using SimaPro software
with ecoinvent (v: 2.2) database.
Reuse- Recovery-and Recycling potential (D)
All gypsum based plasters end up at construction and
demolition waste landfills. However, no possible
benefits of recycling and reuse were taken into account
in the LCA work here.
