CPP CPP Environmental Sustainability & Packaging 2 — Questions and Answers
Question 1: What is a Life Cycle Assessment (LCA) in packaging?
- A financial audit of packaging costs over a product's life
- A systematic analysis of environmental impacts from raw material extraction to end-of-life (Correct answer)
- A durability test measuring how long packaging holds up in transit
- A consumer survey about packaging preferences across the product lifecycle
Correct answer: A systematic analysis of environmental impacts from raw material extraction to end-of-life
An LCA evaluates the total environmental impacts of a packaging system from cradle to grave, including raw material extraction, manufacturing, transport, use, and disposal.
Question 2: Which plastic resin code identifies polyethylene terephthalate (PET), commonly used for beverage bottles and widely accepted by US recyclers?
- #1 (Correct answer)
- #2
- #5
- #6
Correct answer: #1
Resin code #1 identifies PET (polyethylene terephthalate), which is one of the most widely recycled plastics in US curbside programs.
Question 3: What does 'post-consumer recycled content' (PCR) mean on packaging?
- Material recovered from industrial manufacturing scrap before it reaches consumers
- Material that has been used by consumers and collected through recycling programs (Correct answer)
- Material sourced from post-harvest agricultural residues
- Material that has been downcycled into lower-grade products
Correct answer: Material that has been used by consumers and collected through recycling programs
PCR content refers to materials recovered from products that consumers have used and discarded, then collected via recycling infrastructure and reprocessed into new packaging.
Question 4: Which of these packaging materials has the highest recycling rate in the United States?
- Plastic bottles
- Glass containers
- Corrugated cardboard
- Aluminum cans (Correct answer)
Correct answer: Aluminum cans
Aluminum cans consistently achieve the highest recycling rates in the US, often exceeding 50%, because aluminum recycling is highly economical and well-established.
Question 5: What is 'light-weighting' in the context of packaging sustainability?
- Using lighter ink colors to reduce chemical use
- Reducing the weight of packaging material while maintaining functional performance (Correct answer)
- Switching to lighter-colored packaging to reflect heat during shipping
- Decreasing the weight of products inside the package
Correct answer: Reducing the weight of packaging material while maintaining functional performance
Light-weighting is the practice of reducing packaging material weight without compromising structural integrity, protection, or functionality, thereby lowering material use and carbon footprint.
Question 6: What is 'extended producer responsibility' (EPR) in US packaging policy?
- A policy requiring manufacturers to provide extended warranties on packaging machinery
- A framework making producers financially responsible for end-of-life management of their packaging (Correct answer)
- A regulation extending the timeline for producers to comply with labeling laws
- A requirement for producers to extend shelf life of products through better packaging
Correct answer: A framework making producers financially responsible for end-of-life management of their packaging
EPR policies shift the cost and responsibility of packaging end-of-life management (collection, sorting, recycling) from municipalities to the producers who place packaging on the market.
