If I only use one tissue at a time to wipe my nose or dry a tear, what's better for the environment - to throw it in the trash or flush it?
Seems like a waste of water to flush something that would break down so easily and quickly in a landfill.
What kind of tissue are you talking about?Toilet tissue? Flush it.Facial tissue? Throw it in the trash.Toilet tissue is designed to be flushable (it breaks down in water quicker).
AgNuke is right, don't waste water using your toilet as a garbage.
Who cares.... Dispose of any way that makes you happy.
