3R Design
3R Assessment System
Since 1992, Honda has been checking each of its new models with
its 3R preliminary assessment system in order to improve 3R-related
performance.
Design for Reduction (Reduction in Waste Generation)
Reduction in size and weight
As for technology to reduce size and weight, we promote the
use of aluminum die cast frames that can be welded. We adopted
thin-walled hollow construction materials manufactured by Gravity
Die Casting (GDC) process to further reduce the size and weight
of the head pipes of the CBR 1000RR, released in fiscal 2004.
Extension of service life
By December 2004, we expanded the use of Honda’s original
puncture-proof technology called “tuffup tube” to 4.2
million completed motorcycles. We have thus steadily promoted the
use of these unique tubes.
Design for Recyclability
Improved recyclability
For models newly marketed or changed in fiscal 2004, 95% or more
of their materials are recyclable. Also, to further improve recyclability,
we implemented a system using the latest IT technology to collect
and compute recycling-related data. Using this system, we will promote
product designs that attain 95 % recyclability. Honda marks the name
of the material on even small resin parts as much as possible.
Use of recycled resin
We are also expanding the adoption of recycled resin to fenders
and under-covers. For scooters released in fiscal 2004, recycled
resin materials are used in approximately 15% of their resin parts.
Reduction in Substances of Concern
Honda is making efforts to reduce the use of four heavy metals
(lead, mercury, hexavalent chromium, and cadmium), which are said
to have adverse effects on the environment, by the end of December
2005 in all models produced within Japan.
Of the four substances, we have already achieved the voluntary reduction targets of JAMA for lead and mercury in all models earlier than scheduled in JAMA’s guideline. For the remaining two substances, we aim to fully abolish their use by the end of December 2005.

Reduction in the Use of Lead
• A lead-free wheel balancer that had been in use since fiscal
2003 was gradually being used for cast wheels and spoke wheels of
new models, and lead-free wheel balancers were finally applied to
all models in fiscal 2004.
• We achieved all the voluntary reduction targets of JAMA in January 2005.

Reduction in Other Substances of Concern
Honda has been replacing various substances of concern based on
its guidelines on chemical substances. Since December 2002, we have
replaced approximately 60% of those parts containing a tiny amount
of hexavalent chromium with hexavalent chromium-free parts.
