  • 1. Metal Packaging: Solution to Food Waste and World Hunger ? - by reducing post-harvest waste in developing regions Neil Cormack Robson MA, P.Eng., F.Inst. Pkg. President, International Packaging Consultants Ottawa, Canada October 2007 1
  • 2. Food distribution in developingregions - this picture says it all 2
  • 3. In this presentation it is contended that the entire Packaging Sector is under attack:Many states now require, or are proposing, deposits on all types of beverage packaging Consumers in Europe are duped into thinking that recycling charges ensure material recycling Some jurisdictions now restrict all packaging considered non-recyclable There are proposals worldwide to ban or reduce use of plastics in packaging 3
  • 4. Packaging is often a Scapegoat• Governments use packaging initiatives to meet public demand for environmental action, while gaining revenue from waste material sales and reduced waste collection services.• Such measures are justified by negative publicity that discredits the entire packaging industry and ignores its essential role in product distribution.• The packaging sector could prove its worth by concrete contributions to third world hunger alleviation – and thus gain the moral high-ground it rightly deserves 4

  • 13. Desirable Features of Metal Packaging forFood Distribution in Developing Regions• Steel can: - durable, heat-sterilizable, recyclable• Steel drum: - durable, reusable• Alu. can: - durable, pressure-holding, recyclable• Extruded aluminum tube: - durable, collapsible• Alu, foil dish/tray: - lightweight, recyclable• Metal/fibre composite can: - durable• Alu. foil/paper/plastic pack: - lightweight,compact• Alu. foil/plastic pouch: - lightweight, compact, heat sterilizable(only main positive features are recorded above; drawbacks may be advantages for competing pack systems) 13
