Question 1

According to ISO 14040/14044, which sequence correctly lists the four phases of a life cycle assessment?

Accepted Answer

Goal and scope, inventory analysis, impact assessment, interpretation

Answer

ISO 14040 defines goal and scope definition, LCI, LCIA, and interpretation as the LCA phases.

Question 2

A resin supplier publishes a 'cradle-to-gate' carbon footprint for its PET. What does this boundary exclude?

Accepted Answer

Use phase and end-of-life of the finished package

Answer

Cradle-to-gate stops at the factory gate, omitting downstream conversion, use, and disposal.

Question 3

Which material qualifies as post-consumer recycled (PCR) content under common definitions such as ISO 14021?

Accepted Answer

Bottles collected from household curbside recycling and reprocessed

Answer

PCR comes from products that have served their intended use by end users; in-plant scrap is pre-consumer.

Question 4

Which example best represents closed-loop recycling rather than downcycling?

Accepted Answer

Used aluminum beverage cans remelted into new beverage can sheet

Answer

Closed-loop recycling returns material to the same application, as with can-to-can aluminum.

Question 5

Why are carbon-black-pigmented plastic trays frequently lost at material recovery facilities (MRFs)?

Accepted Answer

Near-infrared (NIR) optical sorters cannot reliably identify the polymer

Answer

Carbon black absorbs NIR light, so sorters cannot read the resin and the trays end up as residue.
