Rubbish disposal in the UK is heavily regulated, with most households having on average one 240 litre bin for recyclable waste and one similar bin of non recyclable waste every week; some areas have additional similar or smaller bins for garden, food, or specific recycling waste. Any large rubbish, e.g., old furniture and mattresses, may need to be taken to the local waste depot by the home owner at their own expense, although many councils will collect certain items for free or for a small fee. This leads to some people simply leaving their waste in open public spaces or untended public gardens. This is called fly tipping. In addition, commercial or industrial users may fly-tip to avoid waste handling charges, as will unofficial and unlicensed waste disposal firms.
