The packaging system is designed to use materials and energy as efficiently as possible throughout the product life cycle. This should include material and energy efficiency in interactions with associated support systems such as storage, transport, and handling.
Packaging materials used in the system are cycled continuously through natural or industrial systems, minimizing material degradation.

designing durable products that can be continuously reused, remanufactured, or
recycled. The important implication for packaging is that it must be designed for recovery through either means.
