Design Rules and Guidelines 119

Catalogue of DFE Guidelines
This chapter provides a compilation of DFE guidelines that are com-
monly practiced by manufacturing firms in a variety of industries.
The guidelines are divided into four principal strategies, which were
introduced in Chapter 6 (see Figure 8.1). Each of these strategies is
described at length in the numbered sections below:
A. Design for dematerialization seeks to reduce the required
amount of material throughput, as well the corresponding
energy requirements, for a product and its associated pro-
cesses throughout their life cycle.
B. Design for detoxification seeks to reduce or eliminate the
toxic, hazardous, or otherwise harmful characteristics of a prod-
uct and its associated processes, including waste streams that
may adversely affect humans or the environment.
C. Design for revalorization seeks to recover, recycle, or other-
wise reuse the residual materials and energy that are gener-
ated at each stage of the product life cycle, thus eliminating
waste and reducing virgin resource requirements.
D. Design for capital protection and renewal seeks to ensure
the safety, integrity, vitality, productivity, and continuity of
the human, natural, and economic resources that are needed
to sustain the product life cycle.
