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.
