Outline • Introduction • Methodology • Results • Conclusions
Introduction • Food packaging has a multifunctional role: Container Protection of structural, nutritional and sensory Food losses aspects (Nutrients, resources, energy, Preservation water, land, GHG emissions) (health and safety) Promotion and information
Introduction Food waste: 1.3 billion tonne worldwide 7% of greenhouse gas emissions Plastic packaging: 72% are lost 26% of the total plastics 40% ending in landfills 32% in the ocean & urban areas 14% is recycled & after treatment only 5% of the material cost is retained
Introduction 1a. To increase recycling and 2a. Effective reuse; after-use management 1b. to collection, consider storage and alternative treatment; materials 2b. innovative design and materials that 3a. Help to encourage decarbonise after-use and the industry; reduce environmental 3b. increase impacts resource efficiency
Project aims • To develop key metrics to aid development and selection of new innovative food packaging congruent with the New Plastics Economy • Test using prototype packaging that promises to prolong food shelf life, reduce the amount of packaging and help avoid food waste along the supply chain • The packaging has a double-layer design, with an outer sealed quad containing a suspended inner cavity
Methodology Innovative food packaging • Food damage reduction • Shelf-life extension • Reduction of secondary packaging 1.Features Indicators for packaging selection New • Materials and energy plastics • End-of-life 2. CE economy • Direct and indirect LCA: new versus current packaging 3. LCA
Packaging features 1. Abuse test: • Transport vibration and drop tests 2. Shelf life test: • Modified atmosphere: high-oxygen atmosphere supplemented by carbon dioxide as an antimicrobial 3. Secondary packaging reduction test: • Crates loaded with the same number of layers for each packed product

Conclusions • The methodology exemplifies how to integrate the packaging technical performance with circular economy and life cycle thinking • This particular prototype does not show benefits in comparison with current packaging • But the methodology helps to identify improvement opportunities: Filling position vertical drop main responsible for damage Material selection mono component, low- carbon/renewable materials, higher recycling content & end- of-life management options Use of renewable sources electricity, heat Consider other products
