Industrial Ecology – Winter 2008 – Session 15 – March 3 Material Flow Perspective of Pollution Prevention: Material Flow Perspective of Pollution Prevention: If pollution is caused by material flows, its prevention is also a material issue: There are essentially three ways to reduce or prevent pollution: Dematerialization (less material per economic output) Material substitution (different material) Reuse & recycling (use material and value-added several times)
