What is the primary advantage of a single-stream recycling collection system compared to a dual-stream system?
Answer: Increased resident participation due to collection convenience
Single-stream collection increases participation by making it easier for residents — all recyclables go in one bin — though it typically results in more contamination than dual-stream.
Which collection frequency factor most directly affects the cost per ton of curbside recycling collection?
Answer: Route density (number of stops per route mile)
Route density — how many households are served per route mile — directly drives collection efficiency; more stops per mile lowers the cost per ton collected.
A drop-off recycling center accepts materials 24/7 without staff. What is the most common operational problem associated with unstaffed drop-off sites?
Answer: High contamination and illegal dumping of non-recyclable waste
Unstaffed drop-off sites frequently accumulate contamination and illegal dumping because there is no on-site enforcement to prevent improper disposal.
What is 'set-out rate' as used in curbside recycling program evaluation?
Answer: The percentage of eligible households that place their recycling bin at the curb on a given collection day
Set-out rate measures what proportion of eligible households actually put out their bin for collection, serving as a behavioral indicator of program participation.
Which type of collection vehicle is specifically designed to collect source-separated recyclables in multiple compartments without mixing materials?
Answer: Split-body or compartmentalized collection truck
Split-body trucks have multiple separate compartments allowing collection of different material streams (e.g., fiber vs. containers) in one pass without mixing.
What is 'co-collection' in the context of residential recycling programs?
Answer: Collecting recycling and organics (food scraps/yard waste) on the same truck in separate compartments
Co-collection uses a split-body vehicle to simultaneously collect two separate streams (such as recyclables and organics) in one pass, reducing truck trips and costs.
