Read the first 7 Packaging Sustainability & Environmental Impact flashcards as text

  1. A company claims its packaging is 'carbon neutral.' What is typically required to substantiate this claim legitimately?

    Answer: Measuring the full life cycle carbon footprint and offsetting residual emissions with verified carbon credits

    Carbon neutrality requires a complete LCA-based footprint measurement followed by credible, verified offsets for any remaining emissions.

  2. Which degradation mechanism makes oxo-degradable plastics controversial from an environmental standpoint?

    Answer: They fragment into microplastics without actually biodegrading, leaving persistent polymer particles in the environment

    Oxo-degradable additives cause plastics to fragment physically but the polymer chains do not fully mineralize, generating microplastic contamination.

  3. The 'end-of-life' phase in a packaging LCA for a glass bottle would evaluate which of the following impacts?

    Answer: Energy savings from cullet recycling vs. emissions from landfill disposal

    End-of-life LCA phases assess what happens after consumer use — whether materials are recycled, composted, incinerated, or landfilled and the associated burdens or credits.

  4. Polylactic acid (PLA) packaging is best described as:

    Answer: A biobased, industrially compostable polymer derived from fermented plant sugars

    PLA is synthesized from lactic acid produced by fermenting starch crops (like corn), and it requires industrial composting conditions to degrade.

  5. Which US regulation requires packaging sold in California to meet minimum post-consumer recycled (PCR) content levels for plastic bottles?

    Answer: California's Rigid Plastic Packaging Container (RPPC) law (AB 319 and successor rules)

    California's RPPC program establishes minimum recycled content, source reduction, or reuse requirements for rigid plastic containers sold in the state.

  6. Designing packaging for 'design for disassembly' (DfD) primarily aims to:

    Answer: Allow consumers or sorters to easily separate multi-component packages into mono-material streams for recycling

    DfD ensures that labels, closures, and structural components can be readily separated so each material can enter its optimal recycling or recovery stream.

  7. Which on-pack symbol in the US indicates that a package meets the Sustainable Forestry Initiative (SFI) fiber sourcing standard?

    Answer: The SFI Certified Sourcing mark showing the tree-and-forest logo

    The SFI Certified Sourcing mark signals that forest fiber was sourced according to SFI's responsible forestry and procurement standards.
