The Packaging Guideline covers four (4) categories of packaging material streams namely metals, glass, paper and plastics. The main purpose of this Packaging Guideline is to reduce the volume of packaging ending up in landfill sites by improving product design, increasing quality of production practices and promoting waste prevention. One of the key objectives of this Packaging Guideline is to assist designers in all forms of packaging with a better understanding of the environmental implications of their design decisions, thus promoting good environmental practices without restricting choice.
