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

  1. Which metric is used in Life Cycle Assessment (LCA) to quantify the total greenhouse gas emissions of a packaging material expressed in CO₂ equivalents?

    Answer: Global Warming Potential (GWP)

    Global Warming Potential (GWP) aggregates all greenhouse gas emissions into a single CO₂-equivalent score within LCA.

  2. A brand switching from virgin PET bottles to 50% recycled PET (rPET) content primarily achieves which sustainability benefit?

    Answer: Reduced demand for petroleum-based feedstocks

    Incorporating rPET displaces virgin petroleum-derived resin, lowering fossil resource consumption and associated emissions.

  3. Under the US EPA's waste management hierarchy, which approach is ranked HIGHEST in preference?

    Answer: Source reduction

    Source reduction (preventing waste generation) is the most preferred tier in the EPA hierarchy because it avoids impacts entirely.

  4. Which certification specifically verifies that packaging is compostable in an industrial composting facility within 180 days?

    Answer: ASTM D6400 / BPI Certification

    ASTM D6400 sets industrial compostability standards and BPI certifies products meeting those criteria.

  5. Extended Producer Responsibility (EPR) programs shift the cost of post-consumer packaging management from:

    Answer: Taxpayers and municipalities to brand owners and producers

    EPR policies make producers financially responsible for end-of-life packaging management, reducing the burden on public systems.

  6. The 'circular economy' model for packaging differs from the traditional linear model primarily by:

    Answer: Keeping materials in use through repeated cycles of reuse, remanufacturing, and recycling

    A circular economy design keeps material value in the economy as long as possible rather than disposing after a single use.

  7. Which packaging design strategy can reduce both material use and transportation emissions simultaneously?

    Answer: Lightweighting and right-sizing packaging to minimize void fill

    Lightweighting reduces material consumption while smaller, denser packs improve truck cube utilization and cut transport emissions.
