London Heathrow (LHR), the largest and busiest airport in all of the United Kingdom, has taken an exciting step into the future by completing its rollout of next-generation CT security scanners. This billion-pound investment has eliminated the need for passengers to remove things like liquids and electronic devices from their hand luggage ahead of their bags being scanned at security checkpoints, which it hopes will save time for its guests.

Alongside the operational benefit of this switch, it is also good news from a sustainability perspective, with London Heathrow Airport now also able to save millions of plastic bags that were previously required when passengers did have to remove liquids from their cabin bags. Another welcome by-product of the alteration is the fact that the 100 ml restriction on liquid vessels will no longer apply to travelers departing from Heathrow.
