| Use advice for data set | Scope: This document refers to MDF manufactured in the following plants of the Sonae Arauco Group: Sonae Arauco Beeskow GmbH, Radinkendorfer Strasse 71, 15848 Beeskow, Germany Soena Arauco Deutschland AG, Grecostr. 1, 49716 Meppen, Germany Sonae Arauco Portugal, SA, gua Levada Apartado 168, 3534-956 Mangualde, Portugal Sonae Arauco South Africa (Pty) Ltd, Heidelberg Road, Rocky Drift, White River, Republic of South Africa Sonae Arauco, S.A., Calle de Los Titulos, 29, 47009 Valladolid, Spain The production volume of these plants covers 100 % of the total production of MDF by Sonae Arauco group. System boundary: Type of the EPD: cradle-to-gate with modules C1 to C4 and module D (A1 – A3, C and D) Modules A1 – A3 of the production stage cover the manufacturing of the products, including raw material extraction and processing, energy generation, the production of ancillary products and packaging materials, transport, as well as all waste treatment processes. Eventual benefits of recycling or energy recovery are neglected. The resource aspects of wood were inventoried via material inherent properties such as resource extraction of CO2 from the atmosphere and the lower heating value as the use of renewable energy. Material inherent properties are subject to co-product allocation as ruled in EN 15804. Module A4 covers the transport of the product from the production site to the construction site by a lorry over a default distance of 460 km. Module A5 covers the transport of the packaging material from the construction site and its disposal. Default end-of-waste states for the packaging materials from the packed products at the construction site are defined in analogy for wastes occurring in modules A1 – A3. Eventual further inputs for the installation of the products are not considered due to the broad applicability of the assessed products. The substituted primary material from the net amount of recycled material and from recovered energy exported from the product system in Module A5 is declared in Module D. Module C1 manual deconstruction is assumed. The declared values are thus 0. Module C2 includes the transport of the de-constructed product to a recycling centre by over 50 km. Module C3 covers the preparation of the post-consumer board to become a secondary fuel; the end-of-waste status for recycled wood-based boards is defined as the point where they have been sorted and chipped, ready to be used as secondary fuels. In line with EN 16485, the export of the biogenic carbon stored in the board, expressed in CO2-equivalent is also reported in module C3. Module C4 is not relevant for the assumed end-of-life scenario. The declared values are thus 0. Module D compiles all the benefits and burdens associated with the secondary fuels, secondary materials and exported energy leaving the production system in the modules A5 and C3. Therefore, module D covers the avoided burdens from recycling and from energy recovered from the waste treatment in module A5 as well as the transport of the obsolete boards to a biomass combustion plant, the combustion process itself and the loads and benefits of the substitution of fossil fuels and/or electricity. Substitution effects in module D are always calculated for the net amount of secondary material or secondary fuel of the product system in line with EN 16485. | ||
| Technical purpose of product or process | The area of application for uncoated MDF primarily involves decorative interior furnishings and furniture construction but also interior construction such as trade fair stands and shop design. Apart from an extensive basic range, special MDF variants are also available, e.g. fire-retardant MDF as well as MDF with increased resistance to moisture. | ||

| General comment on data set | Medium density fibreboard (MDF) is a panel-shaped wood-based material in accordance with EN 316 that is manufactured in a dry process by means of compression under heat of wood fibres with adhesive. Uncoated MDF boards can be unsanded, sanded and/or profiled. Due to their various densities and adhesive systems, they can display a variety of material properties and qualities like moisture resistance, fire retardant, load-bearing or others. | ||

| Technology description including background system | The manufacturing of MDF comprises the following steps: 1. Debarking the logs 2. Chipping the wood to chips of approx. 3 x 3 cm in size 3. Boiling the chips 4. Defibring in the refiner 5. Gluing the fibres with synthetic resin 6. Drying the fibres to a residual moisture content 7. Scattering the glued fibre on a forming belt 8. Pressing the fibre mat in a continuous hot press under high pressure 9. Cutting the continuous mat into raw board formats 10. Cooling the raw boards in star coolers 11. Stacking 12. Sanding the top or underside after the air-conditioning phase All leftovers incurred during board manufacture are redirected to be used as fuel to supply the energy needs of the manufacturing process on site. A process diagram is presented below. The production sites are certified according to the following standards: /ISO 9001:2008/; /ISO 14001:2009/; /OHSAS 18001:2007/; /EN ISO 50001:2011/ (German and Portuguese sites). Declared unit: The declared unit for the LCA is 1 m3 of average uncoated Sonae Arauco medium density fibreboard. | ||
