Around Earth Day and recycling awareness weeks, Bing runs recycling questions, and they're genuinely useful trivia. The quiz tests what really belongs in the bin, plus the symbols and timelines that surprise most people.

The symbol and the codes
The recycling symbol is the three chasing arrows, a Möbius loop representing collect, process, remanufacture. The little number inside a triangle on plastics (1 to 7) is the resin code, and 'what does the number on plastic mean' is a common question, it identifies the plastic type, not how recyclable it is.
What can and can't go in
Clean paper, cardboard, glass bottles and many plastics are widely recyclable; greasy pizza boxes, plastic bags and mixed-material packaging often are not. 'Wish-cycling', tossing in non-recyclables hoping they'll be sorted, actually contaminates batches, a fact the quiz likes to teach.
How long things last
Decomposition-time questions are frequent: a plastic bottle can take around 450 years to break down, aluminium cans about 200, and glass effectively never fully decomposes. Aluminium is a star recyclable, it can be recycled endlessly without losing quality.
Answering approach
Learn the three-arrows symbol, the resin-code meaning, and the headline decomposition times. For local specifics on what's accepted, rules vary by area, so the quiz sticks to general facts you can verify quickly.
Frequently Asked Questions
What does the recycling symbol mean?
The three chasing arrows (a Möbius loop) represent the cycle: collect, process, and remanufacture materials.
What does the number on plastic mean?
