Fly-tipping (also known as "fly dumping",[1] and sometimes shortened to tipping) is a British term for dumping waste illegally instead of in an authorised rubbish dump. It is the illegal deposit of any waste onto land, i.e. waste dumped or tipped on a site with no licence to accept waste.[2][3]
The term is derived from the verb tip, meaning "to throw out of a vehicle" and on the fly, meaning "on the wing" — to throw away carelessly or casually.[4]
