Question

What is the most desirable type of recycling? 
A) primary, or closed-loop recycling 
B) secondary, or closed-loop recycling 
C) secondary, or open-loop recycling 
D) tertiary, or figure-eight recycling

Quizplus · Accepted Answer

Primary or closed-loop recycling involves converting materials into the same product repeatedly, without significant loss in quality. This is the most desirable type of recycling because it reduces the demand for raw materials, conserves energy, and minimizes waste. Secondary closed-loop recycling (B) is also good, but involves converting materials into different products, which can lead to a loss of quality and reduced benefits. Secondary open-loop recycling (C) involves converting materials into lower-value products, which is less desirable. Tertiary or figure-eight recycling (D) involves breaking down materials into their basic components, which is often difficult and energy-intensive, and is considered a last resort.
