2ca4874c-e40a-42d7-951b-083d798188aa BENTOMAT ® CLAY GEOSYNTHETIC BARRIERS (GBR-Cs) The values determined to perform the LCA analysis originate from verified CETCO-Poland, Cetco Sp. z o.o. S.K.A. inventory data. The data for the processes come from the following databases: Ecoinvent v.3.6, specific EPDs, ITB-Data. Specific data quality analysis was a part of external ISO 14001 audit. The allocation rules used for this EPD are based on general ITB PCR A. Production of the BENTOMAT® CLAY GEOSYNTHETIC BARRIERS is a line process in one factory of CETCO-Poland, Cetco Sp. zo.o. S.K.A. in Korpele (Poland). Allocation was done on product mass basis. All impacts from raw materials extraction are allocated in A1 module of the LCA. 74.87% Impacts from line production of CETCO-Poland, Cetco Sp. zo.o. S.K.A were inventoried and were allocated to the BENTOMAT® CLAY GEOSYNTHETIC BARRIERS production. Utilization of packaging material was taken into consideration. Module A2 includes transport of raw materials from their suppliers to CETCO- -Poland, Cetco Sp. zo.o. S.K.A. in Korpele. Municipal wastes were allocated to module A3. Energy supply, emissions and wastes were inventoried and allocated to module A3. The life cycle analysis of the declared products covers “Product Stage”, A1-A3, C3, C4 and D modules (Cradle to Gate with options) in accordance with PNEN 15804+A1:2014-04 and ITB PCR A. The details of systems limits are provided in product technical report. All materials and energy consumption inventoried in factories were included in the calculations. It can be assumed that the total sum of omitted processes does not exceed 5% of all impact categories. In accordance with PN-EN 15804+A1:2014-04, machines and facilities (capital goods) required for and during production are excluded, as is transportation of employees. 1 BENTOMAT® – CLAY GEOSYNTHETIC BARRIERS (GBR-Cs) – are factory manufactured clay liners consisting of a layer of bentonite clay encased by at least two geotextiles which are needlepunched together. Additional flexible plastic membrane can be laminated to the outer geotextile. GBR-Cs are known for having consistently low permeability. They have the ability to seal around penetration, self-heal punctures and seal-seam at the overlaps. The bentonite is a naturally occurring mineral that is composed predominantly of smectite. Most bentonites are formed by the alteration of volcanic ash in marine environments and occur as layers sandwiched between other types of rocks. The smectite in most bentonites is the mineral montmorillonite, which is a dioctahedral smectite. Sodium bentonite-based GBR-Cs are designed to provide a hydraulic barrier against many leachates. The swelling bentonite fills up pore space and constricts the flow paths of water, resulting in a low permeability hydraulic barrier. What makes CETCO BENTOMAT® unique? - Needlepunched reinforcement ensure that CETCO GBR-Cs can withstand shear stresses on steep slopes. The high needlepunch density provides higher peak internal shear strengths, without relying on supplemental processing. - Granular bentonite creates less dust during installation than powdered bentonite and is less likely to shift through the needlepunch reinforcement process resulting in consistent hydraulic performance. - It can be custom engineered to meet the project specific needs, available in a many geotextile’s configurations. - Lamination capabilities to provide geocomposite products. What are the advantages of a BENTOMAT® GBR-C? - Self-healing and self-seaming – Sodium bentonite is a naturally occurring clay with a high affinity for water. When hydrated, sodium bentonite swells up to 15 times its original volume. This provides the ability to seal around penetrations, self-heal punctures, and self-seam at the overlaps. - Hydraulic performance – GBR-Cs have a total thickness of less than 1cm and provide better hydraulic performance than several centimeters of compacted clay. A fully hydrated GBR-C typically has a permeability of 2 x 10-11 m/sec, approximately 20 times lower than a typical compacted clay liner permeability. - Resistant to varying weather conditions – GBR-Cs are less likely to be impacted by freeze-thaw or desiccation-rewetting cycles. Freeze-thaw cycles frequently cause compacted clay liners to crack and lead to increased leakage. A clay geosynthetic barrier provides consistent performance and is not subject to performance decreases resulting from varying moisture content, density, or clay content, like compacted clay liners.
