Making the one change not only saves you time and money but also helps the environment

UK airports are keen to ditch the 100ml liquids rule for anyone carrying hand luggage through security this summer. However, until that happens, travellers must continue to limit and pack any liquids from their hand luggage in a clear bag for security reasons.

This has led to a surge in the use of disposable clear plastic bags for toiletries and other liquids across the country. Some UK airports have relaxed the rules around liquids in hand luggage, reducing the need for these plastic bags. However, others still enforce the rule.

The lack of consistency across the UK means many holiday-goers will continue to rely on putting their 100ml liquids in a disposable plastic bag. Even though the UK is eager to abolish the rules as soon as possible, thanks to advanced scanners, you may find that the airport you’re returning from still insists on bagged 100ml liquids.

Fresh data from plastic waste experts at BusinessWaste.co.uk suggests that a staggering 235 million single-use plastic bags could be used in 2025. The data also reveals that an astonishing 3.5 billion bags have been used since the rules were first introduced in 2006, reports the Liverpool Echo.

The 100ml liquid regulation at airports, which mandates that liquids be stored in transparent, resealable plastic bags, was put in place in 2006 after a terror plot to blow up transatlantic flights was prevented. This plot involved the use of liquid explosives that were concealed as soft drinks in carry-on luggage.

With an estimated 313 million passengers expected to pass through UK airports this year, the number of single-use plastic liquid bags used and discarded could hit 235 million. That’s enough to fill two Olympic-sized swimming pools in just one year in the UK.

Data projections indicate that a staggering 3.5 billion bags may have been used at UK airports over the last 19 years. When arranged end to end, this quantity of bags equates to 18 journeys around the Earth’s equator or four times the height of Mount Everest when piled up.

Why does it matter?

These bags are crafted from soft plastics, which are rarely recyclable. They frequently end up in landfill sites, where they can take as long as 1,000 years to decompose.

As these plastic items deteriorate, they can generate minuscule particles known as microplastics. Studies reveal that these pose a threat to both human and animal health. The energy and materials needed to manufacture these bags are depleting our planet’s natural resources, with 98% of single-use plastic products made from fossil fuels or virgin feedstock.

What steps can you take?

Firstly, make sure you’re familiar with the regulations of your departure airport. With many soon to adjust to new rules, there might be no need to bag liquids at all. If you’re checking in luggage, avoid placing any liquids in your hand luggage. This eliminates the requirement for any small plastic bags and could also save you time at security checks, as many will wait until they arrive at security to bag up their liquids, which adds to the queue.

If reusable options aren’t feasible, BusinessWaste is requesting travellers ditch single-use clear plastic bags in favour of reusable ones at UK airports this summer. The company recommends switching to reusable ones and says there is an array of reusable choices available online and in stores, like Boots and Superdrug. However, just make sure they measure 20cm x 20cm, are transparent, have a capacity no greater than one litre, comply with airport regulations, and can be securely sealed (by a zipper).

Another tip is to use airside click-and-collect services for toiletries. This not only bypasses steep airport prices but also eliminates the need to carry liquids in hand luggage, saving space, money, and benefiting the environment.

If you do take liquids in your hand luggage, at most airports:

• containers must hold no more than 100ml
• containers must be in a single, transparent, resealable plastic bag, which holds no more than a litre and measures approximately 20cm x 20cm
• contents must fit comfortably inside the bag so it can be sealed
• the bag must not be knotted or tied at the top
• you’re limited to one plastic bag per person
• you must show the bag at the airport security point

For those who do bring liquids in their carry-on, Gov.uk advises: “Liquids in containers larger than 100ml generally cannot go through security even if the container is only part full. There are some exemptions. Some airports may allow you to take containers of liquid up to 100ml through security in your hand luggage. Check with the airport before you travel. Also, check the rules at other airports you’ll be travelling through – for example, on your return journey.”

Graham Matthews, a plastic waste expert at BusinessWaste.co.uk, says making the swap from disposable plastic bags to reusable ones for 100ml hand luggage liquids should be done as soon as possible to avoid even more waste building up. He said: “The plastic bags we use to bring liquids through airports are a huge blight on the environment.

“While you may only go on holiday once or twice a year, this quickly adds up as the UK now sees around 300 million air passengers a year. We’re really happy to see the new scanners in place and hope that this reduces the reliance on single-use plastic bags.

“However, old habits die hard, and many people will be nervous to change to the new system, or find that their return airport still requires liquids to be bagged. For anyone in this position, and until the new rules are firmly in place, we strongly encourage passengers to consider utilising hold luggage, switching to reusable options, or making use of airside click-and-collect.”
