Background

JFPMA wishes to know about environmental loads for boards produced by the members of JFPMA and enforce that wooden boards are environmental friendly materials compared to other materials.

◎Japan Fiberboard and Particleboard Manufacturers Association (JFPMA)

◎Tokyo University of Agriculture and Technology, Hattori Laboratory (TUAT)

Manufacturers association of boards consists of 19 companies

One research groups about LCA for wooden materials and houses in Japan

Goal and scope for PB

Quantitative calculation of PB from cradle to production and know the average environmental load produced in Japan which leads to the basic unit.

To know environmental loads and show the estimated damage according to the impact assessment by Life cycle Impact assessment Method based on Endpoint modeling (LIME).

5

About LIME (Life cycle Impact assessment Method based on Endpoint modeling) Modest impact assessment tool developed by

LCA Research Center of AIST, Tsukuba.Environmental loads caused by one thousand

materials and eighty land use have been assessed in LIME.

These loads were converted to money value like Japanese yen by questionnaire based on conjoint analysis and treated statistically which is supposed to be a global standard in the field of LCA.

Conclusionsf-CO2, dust and SOx contributed much to the

estimated damage among all environmental loads.

f-CO2 decreases much when wood waste is used as fuel for boiler. But, dust is released more into the atmosphere which increases the estimated damage.

The percentage of b-CO2 was high in PB production. But, this load will be able to deduct to zero by the concept of carbon neutral.

The estimated damages for 1t of PB production were 1,424 yen.

Next targets
