Impregnation process doesn’t generate by-prod- ucts either. 1 2025 2030 "2025-08-26" - "2030-08-26" 2025-08-26 FI The declaration is made for average impregnated timber manufactured at Pölkky Oy’s production site in Oulu. Impregnated timber is made of responsibly sourced pine (Pinus sylvestris) and spruce (Picea abies). Log procurement and the manufacturing processes at Pölkky Oy are FSC® and PEFC certified.1 Dimensions and lengths of the products varies on a wide range as well as the end use of the product. Impregnated wood is commonly used in outdoor applications, such as decking, fences, playgrounds, and landscaping structures, where durability and resistance to weather, moisture, and pests are es- sential. Moisture content for impregnated timber after the process can be 50–60 %, but the water evaporates in time until the wood reaches equilibrium. The density of treated wood in the end is one to two per- cent higher compared to untreated wood. Impregnated products are mainly class NTR A or NTR AB. Also, UC2 products are produced for UK market. Impregnated timber is mainly made from the planed timber produced at Pölkky Oy’s production sites. Also, a small portion of sawn timber is impregnated annually. Sawn timber is procured from Pölkky Oy’s production facilities as well. Occasionally, a batch of raw material may come from a subcontrac- tor. The treatment is carried out through pressure impregnation in a closed process, where all excess preservatives are collected and reused in the next batch. Planed timber procured from a subcontractor is modelled by the Finnish Sawmill association EPD for the average planed timber in Finland (EPD of Finnish Sawn and planed timber 10.06.2021). Moisture content for impregnated timber right after the process can be 50–60 %, but the water evap- orates in time until the wood reaches equilibrium. The density of treated wood in the end is 1–2 % higher compared to untreated wood. The average density of impregnated timber in the modules A4- A5, C and D is 490 kg/m³ in a moisture content of 20 %. EPD RTS PCR 2020 specific dataset ecoinvent database (all versions) This EPD covers life cycle stages for impregnated timber from cradle to gate with options, modules C1- C4, and module D. The product phase, transportation to the building site and installation A1-A5 are included as well as the deconstruction, transportation to waste processing and the waste processing C1-C4. Also, the module D, information beyond construction works life cycle, is in the scope. The sys- tem boarders are shown in the figure 2. The production of production equipment and means of transport, as well as the machinery, equipment and production goods needed for production and in production are excluded from the scope of the assessment, as are the commuting of workers. The screws required for the installation are excluded from the model, as their quantity is small. Also, the plastic waste handling, which comes from unwrapping the plastic bands at the construction site, is excluded from the modelling as the amount of plastic waste from 1 m3 timber package is small. The screws and the plastic represent less than 1% from the weight of the product. No other material or energy flows have been excluded from the system boundaries.
