| Technical purpose of product or process | This Environmental Impact Statement (EPD) refers to cut products produced by BEWI PLASTIMAR in EPS 100 with a nominal density of 20 kg/m3. Applications: Expanded polystyrene (EPS) is a common material used for thermal insulation of buildings, including floors, walls and roofs, among other construction applications. Characteristics: EPS is a solid and rigid insulation material, it is a polymer foam, consisting of air-filled polystyrene closed cells (98% air). As 98% of the material is air, EPS provides good insulating properties at a low weight. Its main properties are low thermal conductivity, resistance to compression and flexion, resistance to traction perpendicular to the faces. Other characteristics of the material include low moisture absorption, long service life, high compressive strength and 100% recyclable. Manufacture: EPS is manufactured through permeating polystyrene beads with pentane, allowing the beads to expand when exposed to steam. This addition of a so-called blowing agent adds 4% - 6% w/w. The expanded polystyrene (EPS) beads are then fed into a block molding machine, where steam and pressure forms large blocks of EPS. The amount of EPS going into the mold determines the density of the block. After molding, the remaining blowing agent, pentane, is aired out and the blocks are cut into the desired shape |

| General comment on data set | Data quality: Specific data for the product composition are provided by the manufacturer. The data represent the production of the declared product and were collected for EPD development in the year of study. Background data is based on EPDs according to EN 15804 and different LCA databases. The data quality of the raw materials in A1 is presented in the table below. Allocation: The allocation is made in accordance with the provisions of EN 15804+A2. Incoming energy and water and waste production in-house is allocated equally among all products through mass allocation. Effects of primary production of recycled materials is allocated to the main product in which the material was used. The recycling process and transportation of the material is allocated to this analysis. Cut-off criteria: All major raw materials and all the essential energy is included. The production processes for raw materials and energy flows with very small amounts (less than 1%) are not included. These cut-off criteria do not apply for hazardous materials and substances. |
