We are absolutely thrilled to announce that Ozoklenz has been featured in Mitie Group’s 2025 ESG report. This recognition marks a huge milestone for us, showcasing how our chemical-free cleaning innovation is transforming one of the world’s busiest airports.
For Summit Hygiene and the Ozoklenz team, this is more than just a mention. It’s a showing that sustainable cleaning is moving into the mainstream, and Ozoklenz is right at the centre of it.
Why this recognition matters
Mitie is one of the UK’s leading facilities management companies, and Heathrow is a global hub where standards for safety, sustainability, and efficiency are set at the very highest level. To be recognised in their ESG report highlights not only the environmental benefits of Ozoklenz, but also the confidence that leading organisations have in our solution.
What is Ozoklenz?
Ozoklenz is a brand of Summit Hygiene, which specialises in chemical-free cleaning systems that will replace up to 90% of cleaning chemicals using aqueous ozone technology.
How Does it Work?
The Ozoklenz chemical machines create a powerful solution called aqueous ozone, which will clean, sanitise, disinfect & deodorise.
The unit copies what happens in nature. Inside the unit, it imitates lightning, and that’s what creates the very fresh smell in the Ozoklenz product. It’s similar to the smell you get after a thunderstorm.
When the unit imitates lightning with oxygen, it creates ozone gas. This gas is then infused into the mains water, creating aqueous ozone, a safe and highly effective cleaner often referred to as “nature’s bleach.” Simply dispense it into your cleaning equipment and go, cleaning has never been safer or more sustainable.
What is Aqueous Ozone?
Aqueous ozone is a powerful cleaning and sanitising solution that comes from a natural process.
In nature, ozone (O₃) is made when lightning splits oxygen in the air (O₂) into single oxygen atoms (O). These then join up with other oxygen molecules to form ozone. Ozone is very reactive, which makes it excellent at breaking down germs, bacteria, and odours.
When ozone is mixed into water, it becomes aqueous ozone – a safe, natural cleaner. The Ozoklenz unit copies what happens in nature, but in a controlled way: it uses electricity to turn oxygen into ozone, then mixes it into normal tap water.
The end result is a cleaning solution that’s chemical-free, non-toxic, and eco-friendly – but still strong enough to sanitise surfaces.
Our Partnership with Mitie Group at Heathrow Airport
After a successful trial in Terminal 4, Heathrow Airport rolled out Ozoklenz across the terminal, with orders placed for a full airport-wide installation. That’s not just an endorsement — it’s proof that Ozoklenz can perform at scale in one of the most demanding environments in the world.
The projected annual savings are impressive:
- 561 plastic 5-litre bottles saved – that’s around 80 kg of plastic.
- 146 kg of CO₂ emissions cut.
- Most daytime cleaning now completed without any traditional chemicals.
This is sustainable cleaning in action, delivering better outcomes for the environment, frontline colleagues, and the millions of passengers moving through Heathrow every year.

What this means for the future
This milestone is only the beginning. As more organisations commit to ESG goals, solutions like Ozoklenz will play a critical role in helping them reduce chemicals, cut waste, and meet sustainability targets without compromising on cleaning standards.
We’re proud to be at the forefront of this movement, and we’re just getting started.
