◎Japan Fiberboard and Particleboard
Manufacturers Association (JFPMA)
Manufacturers association of boards
consists of 19 companies
◎Tokyo University of Agriculture and Technology,
Hattori Laboratory (TUAT)
One of Japanese research group about LCA
for wooden materials and houses
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.

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 conducted on Life cycle Impact
assessment Method based on Endpoint
modeling (LIME)
4

Sawada, Ando, Hattori, Tamura, Mokuzai
gakkaishi, 52(4), 235-240 (2006)
【Impact assessment】 LIME
5
Goal and scope for PB
【Environmental load analyzed】
Resource consumption : LNG, crude oil, coal
Emission to air:CO2 from fossil fuel (f-CO2), CO2

source), hydro carbon, NMHC, SOx, NOx,
NOx(moving source), N2O, CH4
Waste:ash

Conclusions
f-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. However, dust is released more
into the atmosphere which may increase the
estimated damage.
The percentage of b-CO2 was high in PB
production which will be deducted to zero by the
concept of carbon neutral.
The estimated damages for 1t of U and M type
PB production were 1,552 yen and 1,585 yen,
respectively.

Next targets
Inventory analysis and impact
assessment for insulation fiberboard
(IB), medium density fiberboard (MDF)
and hardboard (HB).
Creation of their basic units by the
inventory.
