NEWEST MANAGING INTEGRATED SOLID
WASTE MANAGEMENT SYSTEMS
CERTIFICATION EXAM OFFERED BY THE
SOLID WASTE ASSOCIATION OF NORTH
AMERICA (SWANA) | COMPLETE EXAM Q&A
WITH RATIONALES
1. Which hierarchy of waste management prioritizes
waste reduction at the source?
A) Recycle
B) Reduce
C) Reuse
D) Recover
Correct answer: B
Rationale: Waste reduction at the source is
prioritized in the waste management hierarchy as the
most effective way to minimize waste generation,
emphasizing reduction before reuse, recycling, or
recovery .
2. In an integrated waste management system,
landfills primarily serve to:
A) Recycle waste materials
,B) Incinerate hazardous waste
C) Provide final disposal for non-recyclable waste
D) Compost organic waste
Correct answer: C
Rationale: Landfills are designed as the final disposal
method for waste that cannot be reduced, reused, or
recycled, completing the waste management
hierarchy .
3. Which type of waste is typically accepted at
municipal solid waste landfills?
A) Household waste
B) Medical waste
C) Radioactive waste
D) Industrial hazardous waste
Correct answer: A
Rationale: Municipal solid waste landfills primarily
accept household waste, which is non-hazardous and
common in residential areas .
4. Which of the following is a key component of a
modern sanitary landfill?
A) Incinerator
,B) Liner system
C) Composting pad
D) Waste composting unit
Correct answer: B
Rationale: A liner system is essential in modern
sanitary landfills to prevent leachate from
contaminating groundwater .
5. The primary purpose of a leachate collection
system in a landfill is to:
A) Collect methane gas for energy production
B) Remove and treat contaminated water that has
percolated through waste
C) Provide daily cover material
D) Monitor groundwater quality
Correct answer: B
Rationale: The leachate collection system removes
contaminated water that has passed through the
waste, preventing groundwater contamination .
6. Which gas is the primary byproduct of anaerobic
decomposition in landfills?
A) Carbon dioxide
, B) Methane
C) Nitrogen
D) Oxygen
Correct answer: B
Rationale: Methane is a potent greenhouse gas
generated during anaerobic decomposition in
landfills .
7. According to SWANA's Managing Integrated Solid
Waste Management Systems course, which of the
following is NOT listed as a main topic area?
A) Facility Basics (landfills, transfer stations, WTE)
B) Collection Systems
C) Financial Stock Trading
D) Recycling and Reuse Programs
Correct answer: C
Rationale: The course topics include Planning,
Regulatory Considerations, Facility Basics,
Collection Systems, Recycling, Hard-to-Handle
Wastes, Composting, Emerging Concepts, Funding,
Health and Safety, and Personnel Management;
financial stock trading is not included .
