The Peebol is a disposable urinal bag which converts liquid into a deodorized non-spill gel within seconds.

The bag can be used multiple times, holds up to one litre and can be disposed of in a regular waste bin.

Manufacturers Shewee believe the Peebol is also perfect for sites with no toilet facilities where workers are often forced to hunt for the nearest public loo to answer the call of nature.

One crane driver said: “This sounds like a great idea but it’s just a question of whether contractors will provide this or simply leave us going in a bottle.”
