This dataset represents particle board production as the weighted average of particle boards produced by the members of the European Panel Federation (EPF)
Particleboard (PB) is manufactured from the dry wood-panel production process under pressure and heat from particles of wood (flakes, chips, shavings, sawdust and similar) and/or other lignocellulosic material in particle form (flax shives, hemp shives, bagasse fragments and similar) with the addition of an adhesive.
Particleboard, or particle board (or chipboard in the UK and Commonwealth Nations such as Austra-lia, New Zealand and others), is an engineered wood product manufactured from wood chips, saw-mill shavings, or saw dust, and a synthetic resin or other suitable binder, which is pressed and ex-truded. Particleboard is a composite material according to the standard EN 312. The density of stan-dard particleboard can vary between 650 – 750 kg/m3, whereas densities for low density particle-board can be as low as 250 kg/m3 and range up to 1300 kg/m3 for high density particleboard. Typical thickness is in a range of 3 to > 40 mm.

The inventoried particle board has the following composition:

Undefined unit processes (UPRs) are the unlinked, multi-product activity datasets that form the basis for all of the system models available in the ecoinvent database. This is the way the datasets are obtained and entered into the database by the data providers. These activity datasets are useful for investigating the environmental impacts of a specific activity (gate-to-gate), without regard to its upstream or downstream impacts.

Technology

Particleboard is manufactured by mixing wood particles or flakes together with a resin and forming the mix into a sheet. The raw material to be used for the particles is fed into a disc chipper with between four and sixteen radially arranged blades. The particles are first dried, after which any oversized or undersized particles are screened out. Resin, in liquid form, is then sprayed through nozzles onto the particles. There are several types of resins that are commonly used. Amino-formaldehyde based resins are the best performing when considering cost and ease of use. Urea melamine resins are used to offer water resistance with increased melamine offering enhanced resistance. Phenol formaldehyde is typically used where the panel is used in external applications due to the increased water resistance offered by phenolic resins and also the colour of the resin resulting in a darker panel. Melamine urea phenolic formaldehyde resins exist as a compromise. To enhance the panel properties even further the use of resorcinol resins typically mixed with phenolic resins are used, but this is usually used with plywood for marine applications and a rare occasion in panel production.
