Ahead of the 31 January ban, islanders are told not to bin their used, disposable vapes.
Guernsey Waste has a dedicated bin at the household waste site for disposable vapes and estimate they accept around 50,000 used ones each year.
The devices contain a lithium battery and if this gets crushed, it can combust. This has happened around 40 times at Longue Hougue.
Douglas Button, the site's waste reduction manager, says it is important not to bin them:
"We strongly encourage householders to take used vapes and vape-related products to the Household Waste & Recycling Centre,
where a dedicated vape disposal bin is available.
"Disposing of these items through household waste or recycling carries a very high risk of fire, which can endanger our staff
and public safety."
Lithium batteries contain traces of heavy metal and if they are thrown into the sea, in streams or on land then these chemicals can leach into the environment.
The following items should also be disposed of in the correct bins at Longue Hougue and not in black bin sacks:
• Electronic items
• Gas canisters
• Flares
• Laptops
• Mobile phones
A complete ban on the sale of disposable vapes, including online, comes into effect in Guernsey tomorrow, 31 January.
