Collection Systems Design & Logistics Flashcards

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

Answer: Higher participation rates due to greater convenience for residents

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

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

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

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

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

Answer: Drop-off center or bring system

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.

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

Answer: The total weight of recyclables a collection vehicle carries per trip

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

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

Answer: Side-loader trucks with mechanical arms that lift standardized carts

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

What is a 'transfer station' in recycling and waste logistics?

Answer: A facility where collected materials are consolidated before transport to a MRF or disposal facility

Transfer stations consolidate smaller loads from collection trucks into larger transport vehicles, reducing overall haul costs when the MRF is far from collection areas.
