| Use advice for data set | A flowchart showing the system boundary for planed and impregnated wood is shown below. |
| Technical purpose of product or process | Impregnated planed wood of pine of NTR class A for use in contact with ground and fresh water. The product is manufactured in Bollsta saw mill, Sweden. The product is pressure impregnated with cupperbased impregnation liquid. The products are used for various outdoor applications such as decking, cladding, railing and othter structural elements. Densities of wood products varies depending on raw material species, mostiure content etc. The calculations in for this EPD is based on a density of 560 kg/m3 and an average moisture content of 22% (moisture ratio 29%). This declaration represents an average of impregnation class A and AB. All dimenstions is represented by 1 m3 in this LCA. A recalculation from m3 to m2 can be made with a factor 0,028 m3/m2 for a standard diemension of 28 mm x 120 mm. |

| General comment on data set | Primary production data is specific data based on actual consumption and emission data for the sawing, planing and impregnation processes collected from SCAs production site and represent production year 2019. Data for forestry are based on EcoInvent 3.6 data but modified with updated CO2 data for Swedish Forestry publihsed by Ågren et. al (2021). Data for the impregnation chemical is supplier specific and taken from a published EPD. All other upstream data and data for treatment of production waste is based on data from EcoInvent 3.6 and GaBi 10.0.0.7 GaBi Software System and databases for lifecycle engineering version 10.0.0.7 from Sphera Solutions has been utilised for modelling and calculations. Environmental impact from forestry operations is allocated to roundwood only and nothin to forestry residues such as branches and tops. The prodcution of sawn timber results in a number of valuable by products i.e. raw wood chips for cellulose pulp production as well as saw dust, bark and dry wood chips sold externally for use as biofuels. Allocation of the environmental impact from the saw mill and planing processes has been allocated between sawn timber and by products based on economic revenue in accordance with EN 15804. The environmental impact from forestry operation including trnsport of round wood to the saw mill has been allocated between sawn timber and saw mill by-products based on physical relationship between them i.e. on a dry weight basis in accordance with EN 15804 and EN 16485. No allocation to by-products from the plaining process has been made. Wood residues from the impregnation process is handled as waste. All major raw materials and energy flows are included. The production process for raw materials and energy flows that represent a very small amount (<1%) is not inlcuded. This cut-off rule does not apply to hazardous materials and dangerous substances. |
