1. Which best describes the primary objective of a recycling systems
manager in municipal solid waste programs?
A. Increasing landfill capacity
B. Maximizing waste incineration efficiency
C. Optimizing material recovery and diversion from landfills
D. Eliminating all waste generation
The primary objective is to maximize diversion of recyclable materials from
landfills through efficient collection, sorting, and processing systems.
2. What is the “waste hierarchy” commonly used in recycling systems
planning?
A. Disposal, recovery, reuse, reduction, recycling
B. Recycling, disposal, energy recovery, reuse, reduction
C. Reduction, reuse, recycling, recovery, disposal
D. Disposal, reduction, recycling, reuse, recovery
The waste hierarchy prioritizes preventing waste first, followed by reuse,
recycling, recovery, and lastly disposal.
, 3. What is the main function of a Materials Recovery Facility (MRF)?
A. Burning municipal waste for energy
B. Storing hazardous waste materials
C. Sorting and processing recyclable materials
D. Producing compost from organic waste
A MRF separates mixed recyclables into individual material streams for
processing and resale.
4. Which material is most commonly associated with contamination in
curbside recycling?
A. Aluminum cans
B. Clean cardboard
C. Glass bottles
D. Plastic bags
Plastic bags often contaminate recycling streams because they jam
equipment and are not accepted in many curbside systems.
5. What does “diversion rate” measure in a recycling system?
A. Percentage of waste burned
B. Percentage of waste exported
C. Percentage of waste diverted from landfill disposal
D. Percentage of waste generated per capita
Diversion rate measures how much waste is redirected away from landfills
through recycling, composting, or recovery.
6. Which technology is commonly used to separate ferrous metals in
recycling facilities?
A. Optical scanners
B. Air classifiers
C. Magnetic separators
D. Eddy current separators
, Magnetic separators efficiently remove ferrous metals like steel and iron
from mixed waste streams.
7. What is the purpose of an eddy current separator?
A. Separate glass by color
B. Remove paper from plastics
C. Separate non-ferrous metals like aluminum
D. Compact waste into bales
Eddy current separators use electromagnetic fields to repel and separate
non-ferrous metals such as aluminum.
8. Which recycling stream is most sensitive to moisture contamination?
A. Metals
B. Glass
C. Paper and cardboard
D. Concrete
Paper and cardboard lose value quickly when contaminated by moisture,
reducing recyclability.
9. What is a key benefit of source separation in recycling systems?
A. Increased landfill tipping fees
B. Higher energy use in processing
C. Reduced contamination in recyclable materials
D. Increased hazardous waste production
Source separation improves material quality by preventing contamination
at the point of disposal.
10. Which policy approach encourages manufacturers to take
responsibility for product end-of-life?
A. Pay-as-you-throw
B. Open dumping policy
