Recycling
Attention to product quality in the design phase ensures, firstly, that products have a long life and that, secondly,
all parts of a product may be reused or recycled at the end of that life. An extensive product servicing network
ensures that products can be repaired in the event of the premature failure of a part, or as a way to prolong the
life of a product that would otherwise be considered a candidate for landfill. Eventually there comes a time when
a product is considered beyond repair (for economic reasons or lack of parts), so the parts must be disposed of in
a suitable manner. The disposal should conform to local environmental regulations and be conducted in an
authorized recycling facility.
