| To promote recycling, Honda gives full consideration
to product recyclability right from the earliest development stage. At the development
stage, we strictly evaluate our products from the following three “R”
aspects: Reduce, Reuse, and Recycle. At the design stage, we use environment-friendly materials and structures and parts that do not contain substances of concerns to avoid negative impacts on the environment. |

Honda aims to reduce waste as far as possible and to minimize
the environmental impacts of its production activities by adopting the “3R”
concept in its product design.
 “Reduce”
means to reduce waste by making parts smaller, lighter, more durable, and easily
repairable, which requires a design that provides sufficient functions with fewer
resources.
“Reuse”
means to reuse resources that were wasted in the past, thus reducing waste, which
requires a design that enables easy dismantling and longer product lives.
“Recycle”
means that materials that were wasted are once again used as materials, which
also requires a design that enables easy dismantling and longer product lives.
It is also important that materials that can be easily recycled are used for those
parts that will be dismantled.
It is also necessary to design products for which the use of
substances that do have an environmental impact can be reduced to the minimum.
Recycled materials need to be used as much as possible. They
can be used to make new parts and thereby the use of new materials can be reduced,
which contributes to the efficient use of resources. |

| Side protector braids were
traditionally made from metal and resin. For the CR-V, however, only polypropylene
materials are used. Downsizing by gas assist injection molding made it possible
to reduce the amount of materials used while maintaining the necessary rigidity,
resulting in a reduction in weight by 50% compared with the previous model. |
|
By dividing the bumper, which was integrally molded in the
past, into parts, it can now be more easily dismantled and only the broken
parts need to be replaced with new ones, thereby reducing the generation of waste. |

Traditionally, the following
three different materials were used: polyvinylchloride (PVC) as the covering
material; polypropylene foam (PPF) as the foaming material; and acrylonitrile-butadiene-styrene
(ABS) as the base material. Presently, however, olefin materials mainly composed
of polypropylene (PP) are used for all the instrument panel layers. This makes
it unnecessary to sort the crushed materials and it is now possible to recycle
them as a base material for instrument panels. |

| Acrylonitrile-Ethylene
rubber-Styrene (AES) has been newly developed as a material for the exterior
of motorcycles. AES, which can be clearly colored and is highly light resistant,
is now used for rear cowls and front covers, eliminating the need for subsequent
painting, which was necessary when ABS resin was used as the material. The
use of AES has improved the recyclability of motorcycles. |

| Lead has been
used to ensure the free-cutting ability of crankshafts, etc. Now lead-free
materials are used in the crankshafts for the minicar That’s, the motorcycle
CBR954RR, and for the “GX Series” multipurpose engines. |

| Hexavalent chromium
has been used to ensure resistance to corrosion. Already, chromium-free paints
are used for outboard engines. |
