Active Packaging

7

Active Packaging: „..designed to deliberately incorporate components that would

release or absorb substances into or from the packaged food or the environment

surrounding the food“

* Yildirim S. Active Packaging for Food Biopreservation, in Protective Cultures, Antimicrobial Metabolites and Bacteriophages for Food and Beverage Biopreservation, Lacroix C (ed). Woodhead Publishing: Cambridge, 2011; 460-489.

Potential of Active Packaging

8

Active packaging has potential to be used

to extend the shelf life of the product (fresh produce and foods with low shelf life)

to reduce or remove preservatives from food formulations (fresh, clean label)

to decrease the food lost (food with short shelf lives)

to enable to use particular types of packages (biopackaging, flexibles, transparent

window)

to simplify processing (additional hurdles)

to prepare and to present the food (microwave

susceptors)

to develop new products (some products could be

only possible to develop if active packaging

technologies are applied to preserve the quality)

Climate Change

14

On average, packaging accounts for

about 5% of the energy used in the life

cycle of a food product making it a

significant source of greenhouse gas

emissions.

Production is expected to double again

in 20 years, and quadruple by 2050

Recycling

26

- The packaging industry increasingly invests in maximising the use of recycledfeedstock

- Save resources as it reduces the need for virgin feedstock

- In many cases reduce the required level of energy for processing thefeedstock

- Paper, glass, and metals in particular are being recycled to a large extent, withEurope leading this trend

- Plastic is complex and in some cases it is not possible to recycle because itconsists of a mix of layers

Recycling

Nestle:”100% of our packaging is recyclable or reusable by 2025. We’ve made a number of global commitments to get there, including the elimination of non-recyclable plastics”

Mars: “Plan to use 100 percent recycleable packaging by 2025.”

Unilever: “100% of our plastic packaging will be reusable, recyclable or compostable by 2025”

L’Oréal: “by 2025, 50% of the plastics used in our packaging will either be of recycled origin or bio-sourced”

P&G: “100% of our packaging will be recyclable or reusable”

JNJ:”100% reusable, recyclable or compostable packaging by 2025”

Recycling

• Around 25.8 million tonnes of plastic waste are generated in Europe every year. Less than

30% of such waste is collected for recycling.

• Demand for recycled plastic today accounts for only 6% of the plastics demand in Europe. To

boost the uptake of recycled plastic, the European Commission is taking action to ensure that

by 2030 all plastic packaging placed on the EU market is either reusable or can be recycled in

a cost-effective manner

• EU Specific Targets

60% of plastic before 2025

65% of wood before 2025 and 80% before 2030

80% of iron based metals before 2025 and 90% before 2030

80% of aluminium before 2025 and 90% before 2030

80% for glassware before 2025 and 90% before 2030

90% of carton and paper before 2025
