Shinkiba Factory of
TOKYO BOARD INDUSTRIES CO., LTD.
Product: Wood Particleboard (18M Type) 1.
DESCRIPTION OF THE PRODUCT AND OF THE COMPANY
○ Product Particleboards are wood products, made of small chips of timber, lumber, and wood. First, the wooden materials are crumbled into chips.
The chips are bonded with glues, and then compressed
into board by thermal compressor. Particleboards are used in many places in our daily life, such as frames of integrated kitchen system and subflooring. They have been well utilized in the field of construction, building materials, furniture, and woodworking industries. And 18M Type represents that the bending strength is 18.0N/mm2 and the glue used is melamine resin. ○

２．ENVIRONMENTAL PERFORMANCE DECLARATION Environmental performance declaration is based on the result of the life cycle assessment. ○ Life Cycle Stage The LCA results are classified into the following phases: Manufacturing phase: ・ Transport of recycled wood and of chips obtained from chip suppliers ・ Manufacturing chips at chip suppliers and within Shinkiba Factory ・ Production of raw materials for glues for wood ・ Transport of raw materials for glues for wood ・ Production of glues ・ Manufacturing of particleboards ・ Secondary elaboration of particleboards (cutting) ○ Assumptions for Life Cycle Assessment ① Functional Unit: 1m3 of particleboard ② If coated particleboard is validated, coated surface is quantified in m2 specifying coating material.
The 18 mm-thick panel is used for calculation as a general value. (This 18M Type
particleboard does not have a facing plate.) ③ The calculation is made on the basis of the data collected from November 2003 through October 2004. ④ The below is the flow chart of LCA particleboard.
Chip manufacturing phase, glue production

*Data used concerning electricity is from “Life Cycle Inventory of Standard Electric Power at Receiving End by Ten Electric Power Companies in Japan” written by Matsuno et al . in the bulletin Vol. 77 No. 12, issued by Japan Institute of Energy. *The definition of industrial waste is in accordance with Waste Disposal and Public Cleaning Law.
○ Other Information Since the product is mostly made from wood, avoid the handling near the fire.
In order to lengthen
the life of the product, avoid the use in high-humidity environment. ○ Recycling Declaration ① The product itself can be recycled repeatedly as raw material for particleboard.
For the 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 of integrated kitchen system, case goods, plastic resin, non-ferrous metal, surface material, should be removed. When the particleboard used for construction and/or building material eg subflooring is recycled, plastic resin, non-ferrous metal, height adjusters should be removed. ② Thermal recycling of the product is not recommendable, as the products broken into particle generate 16.7 MJ/kg of energy in combustion.

Appendix USE PHFASE As for quantification in use phase, the transport of particleboard from manufacturing facility to a client was quantified. The table below indicates the results of environmental impact in use phase. And the product in the lower manufacturing phase (eg production of wooden raw materials, production of glues, transport, and manufacturing of particleboards) and in the use phase was quantified separately in conjunction with the impact of global warming (greenhouse gases).

２．INTERPRETATION OF LCA RESULTS The results show that a high level of impact of global warming is observed in the production process of glues.
The results also show that the emission of global-warming gases in the glue
production phase occupied more than 95% of all, the largest, is observed. And as for the second largest, the emission in particleboard manufacturing phase occupies more than 82% is observed. It is assumed because many big motors installed in the facility in the particleboard manufacturing phase and heat sources in pressing such as electricity and city gas are attributed to it.
