| Use advice for data set | Scope: This EPD is prepared as a representative EPD for the Rotkalk in-Board 045 TecTem® product group, calculated with a thickness of 50mm, produced from Knauf Performance Materials GmbH, plant Dortmund, Kipperstraße 19, 44147 Dortmund. The life cycle assessment is based on production data for the period 01/03/2021-28/02/2022. System boundary: Type of EPD: cradle to gate with options. The EPD considers module A1-A3, A4, A5, C1-C4 and D. Module A1 includes provision of all raw materials, production of pre-products (e.g. mining of perlite) and energy supply. Module A2 considers a 300 km transportation to the production site located in Germany. Module A3 considers the manufacturing of the product at the production site including provision of electricity (0,67 kg CO2-eq./kWh) and thermal energy from natural gas. The production of packaging materials is also included. Module A4 considers a 230 km truck transport to the construction site. Module A5 considers the treatment and disposal of packaging materials. Benefits for potential avoided burdens due to energy substitution of electricity and thermal energy generation are declared in module D. Additionally, adhesive tenant and interior plaster are necessary to install the board and are therefore declared in module A5. Module C1 considers the dismantling of the product at EoL with an excavator. Module C2 considers a 50 km transportation to waste processing by truck. Two scenarios are considered in the End-of-life: recycling (1) and landfilling (2). Module C3 (Scenario 1) calculates the recycling processing efforts, in which the product is processed (considering 3 % losses) and a material benefit for roadworks (gravel) is applied in module D. For C3/1 the results are '0'. Module C4/1 (Scenario 2) considers landfilling of the product. For C4 the results are '0'. Module D includes potential benefits for the thermal and electrical energy generated in module A5 due to packaging treatment and also the material benefit due to the product processing in module C3. Avoided burdens have been calculated by the inversion of electricity grid mix and thermal energy from natural gas. The material benefit is calculated by using a generic data set for gravel. Module D/1 accounts for the avoided burdens for electricity grid mix and thermal energy from natural gas due to packaging incineration resulting from A5 only. The CO2 incorporation in the product (from the sequestration in the starch) and the packaging (from the sequestration in the kraft paper and wooden pallets) is considered. The C-balance is closed by considering the biotic CO2 emissions according to the incorporation on the input side. Period under review The period under review for the collection of production data is the following period: March 2021 – February 2022. | ||
| Technical purpose of product or process | Rotkalk in-Board 045 TecTem® 50mm was developed for the interior insulation of exterior walls and interior ceilings (WI, DI according to DIN 4108-10). It is the ideal solution for the energy-efficient renovation of facades where external insulation is not possible, such as listed facades or facades whose appearance is to be preserved, such as exposed brick facades. | ||

| Technology description including background system | The used raw materials are expanded perlite, mineral binder and thickener The crushed, sieved and pre-dried raw perlite is expanded in the perlite oven at a temperature of approx. 1.000°C. The further production process of the Rotkalk in-Board 045 TecTem® 50 mm to 200 mm is divided into the following steps: Binder preparation: A highly viscous binder gel is produced through a continuous thermal process Mixture preparation: The binder gel produced is mixed with the main component perlite. Shaping: The produced mix is transported to the press by a bucket elevator and pressed into a plate measuring 1250 x 1250 x 50-200mm. Drying: The pressed green compact is then transported to the dryer by vacuum transport and dried in a continuous process. Formatting: The motherboards are assembled to the final format of 625 x 416 x 50-200mm. Packaging: The panels are bundled, packed in boxes, stacked on pallets and wrapped with PE-LLD stretch film. Technical data: Technical datasheets can be downloaded from the website: https://knauf.com/de-DE/p/produkt/rotkalk-in-board-045-tectem-r-25316_0010 Declared unit: This declaration refers to the declared unit of 1 m of insulation material as board Rotkalk in-Board 045 TecTem® 50 mm. The weight of the product is 4.75 kg/m. | ||
