CEH Waste Management and Sustainability 2 — Questions and Answers
Question 1: What does the term 'waste diversion rate' measure in a hospitality sustainability program?
- The speed at which waste is removed from guest rooms
- The percentage of waste diverted from landfill through recycling or composting (Correct answer)
- The ratio of housekeeping staff to waste bins on each floor
- The cost savings from reducing waste collection frequency
Correct answer: The percentage of waste diverted from landfill through recycling or composting
Waste diversion rate measures the percentage of total waste that is kept out of landfills via recycling, composting, or other recovery methods.
Question 2: A hotel wants to implement a composting program for food and organic waste. Which department should the Executive Housekeeper coordinate with most closely?
- Front desk and reservations
- Food and beverage / kitchen operations (Correct answer)
- Sales and marketing
- Engineering and maintenance
Correct answer: Food and beverage / kitchen operations
Food and beverage generates the bulk of organic waste, so coordinating with the kitchen is essential for a successful composting program.
Question 3: Which of the following chemicals is considered most harmful if improperly disposed of down a drain in a hotel laundry facility?
- Diluted fabric softener
- Chlorine bleach in large concentrations (Correct answer)
- Warm water rinse
- Mild liquid detergent
Correct answer: Chlorine bleach in large concentrations
High concentrations of chlorine bleach can damage water treatment systems and harm aquatic ecosystems when improperly drained.
Question 4: What is the primary purpose of a Material Safety Data Sheet (MSDS/SDS) in waste management?
- To list the wholesale cost of cleaning supplies
- To provide hazard, handling, and disposal information for chemical products (Correct answer)
- To track the number of cleaning products used per room
- To certify that a product meets eco-label standards
Correct answer: To provide hazard, handling, and disposal information for chemical products
An SDS provides critical information on safe handling, storage, and proper disposal of chemical substances to protect workers and the environment.
Question 5: A housekeeping department switches from individual soap bars to bulk-dispenser soap systems. What sustainability benefit is most directly achieved?
- Reduced water consumption per guest
- Reduction in single-use plastic packaging waste (Correct answer)
- Lower chemical concentration in wastewater
- Improved indoor air quality
Correct answer: Reduction in single-use plastic packaging waste
Bulk dispensers eliminate the individual plastic wrappers on single-use bars, directly reducing plastic packaging waste sent to landfill.
Question 6: When selecting a waste hauler for a hotel, what sustainability criterion should an Executive Housekeeper prioritize?
- The hauler with the lowest bid price regardless of practices
- Whether the hauler offers recycling and composting diversion services (Correct answer)
- Whether the hauler operates on weekdays only
- The distance of the hauler's office from the property
Correct answer: Whether the hauler offers recycling and composting diversion services
A waste hauler that provides recycling and composting services helps the hotel achieve higher diversion rates and meet sustainability goals.
Question 7: Which metric best helps an Executive Housekeeper benchmark a hotel's waste reduction progress over time?
- Total number of housekeeping staff employed
- Pounds of waste generated per occupied room night (Correct answer)
- Number of guest complaints about cleanliness
- Annual laundry chemical expenditure
Correct answer: Pounds of waste generated per occupied room night
Measuring waste per occupied room night normalizes data for occupancy fluctuations, giving an accurate picture of waste reduction efforts.
