Metal Packaging: Solution to Food Waste and World Hunger ?

- by reducing post-harvest waste in developing regions

Food distribution in developing regions - this picture says it all

3

Consumers in Europe are duped into thinking that recycling charges ensure material recycling

There are proposals worldwide to ban or reduce use of plastics in packaging

Many states now require, or are proposing, depositson all types of beverage packaging

Some jurisdictions now restrict all packaging

considered non-recyclable

In this presentation it is contended thatthe entire Packaging Sector is under attack:

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

The Two Views of Waste

In the industrialized world In developing countries

Industrialized Countries Less Developed Countries

High packaging waste Low packaging waste

Low food waste High food waste

Low food-borne disease High food-borne disease

Long distribution distances Only local distribution

Season independent Season dependent

Convenient preparation Prepare from scratch

Low preparation waste High preparation waste

Balanced diet possible Balanced diet difficult

Food Distribution around the World

Food Availability Customer Attractions

Scarce Customer will buy any available food

Generally available Better product quality attracts some customers

Quality food abundant Provision of convenience packaging

Food oversupply Graphics emphasis on brands, quality

Extreme consumerism Appeals to lifestyles & fantasies Package becomes

entertainment Package becomes the product

Desirable Features of Metal Packaging for Food 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)

23

Principal Features required to expand Metal Packaging’s Role in reducing Food Waste

and alleviating Hunger

• Converted pack materials easily, quickly and economically delivered to packing stations;

• Reliable, low-cost pack/product sterilization, filling and hermetic sealing processes;

• Resistance to harsh distribution and storage conditions;

• Adequate (at least one year) shelf life;• Easy, low-cost pack material recovery and

recycling to ensure sustainability• Minimal decoration !
