CRP Collection Systems Design & Logistics

Question 1

What is the primary advantage of single-stream recycling collection over dual-stream?

Accepted Answer

Higher participation rates due to greater convenience for residents

Answer

Single-stream collection (all recyclables in one bin) maximizes convenience, which research consistently shows increases household participation and set-out rates.

Question 2

What does 'route optimization' mean in recycling collection logistics?

Accepted Answer

Designing collection routes to minimize travel distance, time, and fuel consumption

Answer

Route optimization uses mapping software and data analysis to sequence collection stops in the most efficient order, reducing operational costs and vehicle emissions.

Question 3

Which collection system type best serves low-density rural areas with limited collection frequency?

Accepted Answer

Drop-off center or bring system

Answer

Drop-off centers are cost-effective for rural areas where widely spaced homes make door-to-door curbside collection economically impractical due to high per-stop costs.

Question 4

What does 'payload' mean in the context of recycling collection vehicle efficiency?

Accepted Answer

The total weight of recyclables a collection vehicle carries per trip

Answer

Payload is the actual weight of collected material per trip; maximizing payload per route mile is a key efficiency metric for managing collection costs.

Question 5

Which type of recycling collection vehicle is most commonly used in automated curbside programs?

Accepted Answer

Side-loader trucks with mechanical arms that lift standardized carts

Answer

Automated side-loaders use hydraulic arms to lift and empty standardized carts, reducing labor costs and worker injury risks compared to manual collection.
