Source reduction opportunities for manufactures of PS products include:
1. Designing products and packaging in such a manner that less material is used in production and/or transportation.
2. Increasing the useful life of products (including making products reusable).
3. Replacement of single-use products that cannot be recycled effectively with recyclable or compostable alternatives.
PS product manufacturers have argued that competitive business pressures to use materials more efficiently have already driven most production methods to their optimum level. Accordingly, there are few opportunities to further change product design or packaging to use less material. Opportunities for reuse are discussed later in this report. Substituting a compostable material for a nonrecyclable material would be most effective in situations where the material was included in a food-waste composting program.
