Product description: Particleboards are wood products, made of small chips of timber, lumber, andwood. First, the wooden materials are crumbled into chips. The chips are bonded with glues, andthen compressed into boards by a thermal compressor.
Particleboards are used in various places in our daily life, such as frames of integrated kitchensystems or subflooring. They have been well utilized in the field of construction, building materials,furniture, and woodworking industries.
UN CPC code: 31431
Geographical scope: The geographical scope of this EPD is Japan.

Cut-off rules: Data collection includes major raw material and energy consumption. All inputs andoutputs of the unit processes, for which data is available for, are included in the calculation. There isno neglected unit process of more than 1% of the total mass or energy flows.The module specific total
neglected input and output flows also do not exceed 5% of the energy usage or mass.
Allocation rules: The survey makes assignments based on physical properties (mass, volume, etc.)
according to EN 15804.
Climate impacts of the energy sources behind the electricity grids: 191g CO2 eq./kWh.
Information about the scenario: The end-of-life modelling is based on the most realistic scenario anduses average values for wood waste treatment in the Tokyo metropolitan area of Japan.

Additional information
Information about recycling: The product itself can be recycled repeatedly as raw material forparticleboards. For this purpose, plastic resin, non-ferrous metal, cloth, paper etc. should be removed
from the product. In recycling the particleboard used for furniture or woodworking such as frames ofintegrated kitchen system, case goods, plastic resin, non-ferrous metal, surface material, should beremoved. When the particleboard used for construction and/or building material e.g, subflooring, isrecycled, plastic resin, non-ferrous metal and height adjusters should be removed.
Japanese standards equivalent to EN Standard: For the testing method of formaldehyde, Japanesestandards are applied, and EN Standard is not applicable to this product because the horizontal
standards for measurement of the release of formaldehyde from construction products using
harmonized test methods according to the provisions of the respective technical committees for
European product standards are not available.
EN 312 is applied in the EU market, but JIS A1460, which is an equivalent standard to EN312, isapplied in the Japanese market.
Japanese Standard
EN Standard
JIS A 5908
EN312, 1350-1
JIS A 1460
EN120, 717-1*Desiccator method is used.
(Products are distributed and used only in the Japanese market)
Other information: Since the product is mostly made from wood, avoid the handling near the fire. Inorder to lengthen the life of the product, avoid the use in high-humidity environment.
Consideration of recycling: Materials used for the particleboards manufactured by Tokyo BoardIndustries Co., Ltd. are woodchips from demolition materials and classified as “Material Recycle” in theconcept of wood cascading use. Forests play a specific and important role in the global carbon cycle
by absorbing carbon dioxide during photosynthesis, storing carbon above and below ground. Burning
recyclable wood out or using it for thermal recycling contributes to CO2 release into the atmosphereand causes global warming (See Figure 3).The most efficient use of wood is to reuse or recycle theresource as many times as possible, desirably from larger units to smaller composites, and finally to
only burn the wood waste, that cannot be recycled as thermal recycling. While cascading the forestbased resource, afforestation and proper forest management should be carried out. It could increase
the carbon stored in wood and consequently minimize its contribution to greenhouse effects.
*Afforestation described in
the model above is notcovered by this EPD, for
conducting the life cycle
environmental impact
assessment at the stage ofthe primary use. The roughwood described in the life
cycle flow diagram are thematerials with no market
value and diverted from thewaste stream, which is not aresource produced by theafforestation or forestry
activities carried out toprovide raw materials.
