only if you think you have an infection or something. if you have no symptoms of anything then you don't need to see a doctor. if you clean used applicators then you can by all means reuse them, they're just plastic...
I'm not sure how you use a previously used tampon applicator - it's a one-time use item, it's not like you can re-load tampons into an applicator. Unless it's someone elses applicator there's not a big concern here for infection or contraction of any sort of STD. If it was an applicator you had used previously then chances are there's not that much bacteria on it, it also only hits the vaginal opening.

No. End of story. Propane can not be reused or recycled.
there is no drain all r12 should be vacuumed out w/ a reclaimer and reused
they should be recycled because the plastic coating around it can be reused to make things such as plastic water bottles
Recycling is when items that can be reused are reused, and the act of saving those items for reuse. Some of the items that can be reused are paper and most plastics.
No.
tRNA can be reused since it regains its structure after translation with the amino acids. ALso, mRNA can be reused while the end of it is still in use.

It can be but make sure the plant grown in it previously was not diseased, there will also be very little nutrient left in it so some must be added. It is probably better to use it as a mulch on borders to be sure.
A kind of energy that can be used and reused any number of times.
