| Use advice for data set | Scope: Approx. 1.5 million m³ HDF boards were manufactured in Germany in 2009, of which more than 23% was accounted for by members of the association. The contents of this Declaration are based on information provided by members whose production accounted for 360,000 m³, whereby the technology represented here is representative for all members. System boundary: The Declaration complies with an EPD "from cradle to plant gate, with options". It includes the production stage, i.e. from provision of the raw materials through to production (cradle to gate, Modules A1 to A3), and parts of the end-of-life stage (Modules C2 to C4). It also contains an analysis of the benefits and loads over and beyond the product's entire life cycle (Module D). Module A1 analyses the provision of wood from forestry or in the form of ancillary products from the wood industry, the provision of other improved wood products and the provision of glues and other ingredients. Transport of these substances is considered in Module A2. Module A3 comprises the provision of fuels, resources and electricity as well as the production processes on site. Essentially, these involve the preparation, drying, sorting and compression of raw materials. Module C2 considers transport to the disposing company while Module C3 handles preparation and sorting of waste wood; Module D analyses thermal utilisation and the ensuing benefits in the form of a system extension. |

| Technology description including background system | Industrial wood and wood chips are used in the production of HDF. The logs are stripped of bark, chopped and boiled along with the wood chips. The boiled wood chips are defibrated under high pressure in a refiner and then glued. The glued fibres are dried and scattered in the corresponding layers for pressing. The compressed boards or stream of boards are cut and formatted. Once the glue has hardened in full, the boards are packed. Declared unit: The declared unit under ecological review is the provision of 1m³ high-density fibreboard with a mass of 849.92 kg/m³, a water content of 7.26% and a glue and additives content of 14%. The composition complies with the weighted average by production volume. |
