Designing for Reuse
Xerox maximizes the end-of-life potential
of products and components by
considering reuse in the design
process. Machines are designed for
easy disassembly and contain fewer
parts. Parts are durable – designed
for multiple product life cycles. Coded
with instructions on how to dispose, the
parts are also easy to reuse or recycle.
As a result, equipment returned to Xerox
at end-of-life can be rebuilt to as-new
performance specifications, reusing
70–90% of machine components (by
weight), while meeting performance
specifications for equipment with parts
that are all new.
Xerox also designs product families
around modular product architectures
and a common set of core components.
These advances offer us many options
for breathing new life into old equipment.
A returned machine can be rebuilt as
the same model through remanufacture,
converted to a new model within the
same product family, or used as a source
of parts for next-generation models.
Improved forecasting of equipment
returns has allowed Xerox to rely on
previous generations of equipment as a
source of components for products in
development. A Xerox product whose
designs are based on previous models
may have 60% of its parts in common
with previous equipment.
The practice of reusing parts reduces the amount of raw material needed to manufacture
new parts, which generates several hundred million dollars in cost savings each year.
And there are energy savings. We estimate that in 2006, energy savings from reused
parts totaled six million therms (170,000 megawatt hours) – enough energy to light more
than 136,000 U.S. homes for a year.
