During this year’s fair, held at the end of September, 70 men and one woman were reported for public urination outside designated areas, more than double the previous year, according to local newspaper Thurgauer Zeitung.
To deal with the growing problem, Gregor Wegmüller, director of the fair, is looking to a new invention by German company Adamus Group, which makes pocket-sized urinals designed for relieving yourself on the go.
This portable urinal bag contains a gel which solidifies urine and neutralizes odour, its creator Marc Collinet told the paper.
It has a capacity of 750 millilitres – the size of “two male bladders” – and comes in three versions, for men, women and children.
After use the bag can then be thrown away.
“These portable loos are an exciting commercial idea,” Wega director Wegmüller told Thurgauer Zeitung on Wednesday.
“Perhaps the pocket urinals would go some way to solving the problem of public urination.”
However Wega has not yet decided on the best way to distribute the bags at next year’s event, held from September 24th to 28th 2015.
Some 100,000 people attended this year’s fair, which comprised 500 exhibitors, a programme of concerts and demonstrations and the Luna Park fun fair.
