Question 1

Which refrigerant type is considered the most environmentally preferred for modern vending machines due to its low global warming potential (GWP)?

Accepted Answer

R-290 (propane)

Answer

R-290 (propane) is a natural hydrocarbon refrigerant with a GWP of just 3, making it far more environmentally friendly than synthetic HFCs.

Question 2

What does the term 'carbon footprint' refer to in the context of vending machine operations?

Accepted Answer

The total greenhouse gas emissions associated with operating a vending machine

Answer

A carbon footprint measures the total greenhouse gases (primarily CO2 equivalent) emitted through machine energy use, logistics, and product lifecycle.

Question 3

A vending operator wants to reduce single-use plastic waste. Which product packaging strategy best supports this goal?

Accepted Answer

Prioritizing products in recyclable or compostable packaging

Answer

Prioritizing recyclable or compostable packaging directly reduces single-use plastic waste entering landfills.

Question 4

Under EPA regulations, what must vending operators do before disposing of refrigeration equipment containing CFC or HCFC refrigerants?

Accepted Answer

Recover the refrigerant using certified equipment before disposal

Answer

EPA Section 608 regulations require certified technicians to recover refrigerants before disposal to prevent ozone-depleting emissions.

Question 5

Which of the following is a key benefit of deploying telemetry systems in vending machines from a sustainability perspective?

Accepted Answer

They reduce unnecessary service trips by providing real-time inventory data

Answer

Telemetry reduces fuel consumption and emissions by enabling data-driven routes that eliminate unnecessary service visits.
