1. A Maryland Recycling Coordinator is developing a municipal recycling
program and must prioritize waste hierarchy principles. Which of the
following best represents the correct order of priority in sustainable
waste management practices?
A. Recycling, disposal, reuse, reduction
B. Disposal, recycling, reduction, reuse
C. Reduction, reuse, recycling, disposal
D. Reuse, disposal, reduction, recycling
Answer: C
Rationale: The waste hierarchy prioritizes reducing waste first,
, followed by reuse, then recycling, and finally disposal as the least
preferred option because it minimizes environmental impact and
conserves resources.
2. When calculating a community’s recycling rate, which formula is most
appropriate for determining the percentage of waste diverted from
landfills?
A. (Total waste generated ÷ recycled waste) × 100
B. (Recycled waste ÷ total waste generated) × 100
C. (Landfilled waste ÷ recycled waste) × 100
D. (Total waste ÷ landfill capacity) × 100
Answer: B
Rationale: The recycling rate is determined by dividing the amount of
recycled waste by the total waste generated and multiplying by 100
to express it as a percentage.
3. A recycling coordinator is implementing a single-stream recycling
system. What is a primary advantage of this system compared to
multi-stream recycling?
A. Increased contamination rates
B. Reduced participation rates
C. Simplified collection process for residents
D. Higher sorting costs at the household level
Answer: C
Rationale: Single-stream recycling simplifies participation by
, allowing residents to place all recyclables in one bin, thereby
increasing convenience and participation rates.
4. Which material is generally NOT accepted in curbside recycling
programs due to contamination concerns?
A. Aluminum cans
B. Cardboard boxes
C. Plastic bags
D. Glass bottles
Answer: C
Rationale: Plastic bags often cause operational issues in sorting
facilities and are typically excluded from curbside programs due to
contamination and machinery interference.
5. What is the primary environmental benefit of recycling aluminum
compared to producing new aluminum from raw materials?
A. Increased landfill capacity
B. Reduced energy consumption
C. Higher transportation costs
D. Increased mining activity
Answer: B
Rationale: Recycling aluminum uses significantly less energy than
producing it from raw bauxite ore, thereby reducing environmental
impact.
, 6. In Maryland, what is the main purpose of a Materials Recovery Facility
(MRF)?
A. Incinerating hazardous waste
B. Sorting and processing recyclables
C. Producing compost
D. Storing landfill waste
Answer: B
Rationale: A Materials Recovery Facility is designed to sort, separate,
and prepare recyclable materials for market distribution.
7. Which of the following is an example of source reduction?
A. Composting food waste
B. Using reusable shopping bags
C. Recycling newspapers
D. Landfilling yard waste
Answer: B
Rationale: Source reduction involves minimizing waste at its origin,
and using reusable bags reduces the need for disposable materials.
8. A recycling audit reveals high contamination in collected materials.
What is the most effective first step to address this issue?
A. Increase landfill capacity
B. Improve public education and outreach
C. Stop recycling collection
D. Raise waste disposal fees
