Which refrigerant blend is commonly found in newer residential window air conditioners manufactured after 2010?
Answer: R-410A
R-410A became the dominant refrigerant in residential air conditioning equipment after R-22 phase-out requirements pushed manufacturers to adopt this HFC blend.
What is the environmental risk of improperly disposing of cathode ray tube (CRT) televisions mixed with major appliances at a shredder?
Answer: Lead oxide in CRT glass contaminates metal fractions and shredder residue
CRT glass contains up to 8 pounds of lead oxide per unit, which contaminates metal fractions and shredder residue when not removed before shredding.
A facility processes 500 refrigerators per day. What type of generator status would they likely hold under RCRA for their hazardous waste?
Answer: Large Quantity Generator
High-volume appliance recyclers typically generate enough hazardous waste (oils, refrigerants, mercury) to qualify as Large Quantity Generators under RCRA.
What is the primary purpose of 'whole-unit destruction' verification in appliance recycling programs?
Answer: To prevent refurbishment and resale of inefficient appliances that were meant to be retired
Whole-unit destruction verification ensures that appliances collected for retirement are actually destroyed and cannot be refurbished and returned to service, defeating the energy savings purpose.
Which international agreement restricts the export of hazardous wastes from developed to developing countries and affects appliance recycling material flows?
Answer: Basel Convention
The Basel Convention restricts transboundary movements of hazardous wastes, affecting how appliance recycling residues and certain recovered materials can be exported internationally.
When processing a side-by-side refrigerator with an in-door ice maker, what additional material stream must recyclers consider compared to a standard refrigerator?
Answer: Water filtration components that may contain carbon media
Ice maker-equipped refrigerators contain water filters with activated carbon media, which must be managed as a separate waste stream and may have specific disposal requirements.
What does 'recycling efficiency standard' mean in the context of the RAD program for CFC-containing refrigerators?
Answer: The minimum percentage of appliance materials that must be recycled versus landfilled
The RAD program recycling efficiency standard requires that a minimum percentage by weight of each collected appliance be recycled rather than disposed of in a landfill.
