Question

SLPaper 1

The 'cradle-to-cradle' (C2C) design framework categorizes materials into two distinct 'nutrient' types to ensure they can be returned to productive use. Which row correctly identifies the intended end-of-life path for these material categories?

	Biological Nutrients	Technical Nutrients
A	Incineration for energy recovery	Disposal in managed landfills
B	Return to the natural biosphere	Circulation in industrial cycles
C	Processing via open-loop recycling	Breakdown via anaerobic digestion
D	Storage in specialized facilities	Conversion into organic compost

HLPaper 1

SLPaper 1

A manufacturing team is analyzing three different end-of-life pathways for their consumer electronics line. The table below describes the specific processes applied to each product category.

SLPaper 1

The table below describes two different approaches to managing products and materials at the end of a specific life stage.

SLPaper 1

A company that produces aluminium beverage cans reduces the thickness of the can walls by 0.05 mm while maintaining the required pressure resistance. This change significantly decreases the total volume of raw material required for the same production output.

Which waste mitigation strategy is best described by this design improvement?

I	The engine is completely broken down into its smallest individual parts.
II	Every part is chemical-cleaned and inspected using high-precision sensors.
III	Degraded parts are substituted with upgraded components that meet current standards.
IV	The engine is reassembled and certified to perform with a full new-product warranty.

Category 1	The product is completely disassembled, and all components are inspected; it is then rebuilt using new and original parts to meet the same quality and performance standards as a new product.
Category 2	The product is cleaned and serviced to return it to a good, functional working order, though it may not meet its original factory performance specifications.
Category 3	The product is broken down so that its constituent materials can be processed and used as raw material for the manufacturing of new, different products.
