Hygeia Spray BottleThe past year has been an enormously exciting and successful one for leading innovators in alternative green technologies GreenTeck Global.

That’s the view of founder and CEO David Thurston of the Oxford-based company – and is particularly true of its growth in the university sector.

From what was virtually a standing start the company is now working with more than two dozen universities and colleges across the length and breadth of the country where it has either already completed successful installations or currently has products on trial.

“One of the really exciting things is that it has been a genuinely collaborative process where we are learning together,” says Thurston. “Universities are coming to us, usually via their facilities or building management staff, and saying: ‘This is the problem. What can you do to help?’ and between us we are developing solutions.”

“As a company our profile within the industry has also risen: through our website and social media, attending conference and events such as CUBO and also through magazines like University Business.”

Ozone is the world’s most powerful, naturally occurring, deodoriser and sanitiser

Although GreenTeck Global manufactures and distributes a wide range of products – which have application across an equally large number of industry sectors – providing sustainable, energy conscious and cost-effective solutions – the ones that seems to have caught the eye of universities are the AIRTECK family of trioxygen-producing units.

Trioxygen or ozone (O3) is the world’s most powerful, naturally occurring, deodoriser and sanitiser. The units all produce ozone as a gas, which, after it has finished its work, reverts back to ordinary oxygen (O2). So use is completely safe and free of any COSHH regulations. The units come in sizes from single, room-sized ones that plug into an ordinary, domestic, electric socket to much larger, portable, models capable of handling air volumes such as conference halls and sport facilities.

Student accommodation has provided a fertile testing ground for the products: and not just for deodorising and sanitising; since the trioxygen is also extremely effective in eradicating the mould spores that flourish in damp, humid conditions, combats smoke-logging and has even been used to remove odours caused by cannabis smoking.

Also triggering a lot of interest right now is the brand-new Hygeia spray bottle. The actual operation of the trigger-spray produces trioxygen in solution in ordinary tap water. This means there is literally no dilution in effectiveness as the spray is delivered, at full power, exactly when and where it is needed – cleaning as well as deodorising and sanitising.


AirTeck 5000P receiving a degree in cleaning

A new generation of powerful deodorisers and sanitisers is helping clean up on campuses across the UK.

The Gteck range from Oxford-based Greenteck Global is harnessing the power of trioxygen – and elemental force as old as the planet itself – to provide high-tech cleaning solutions for the 21st century.

Trioxygen, or ozone (O3), occurs naturally in our atmosphere, most noticeably in the ozone layer, and is produced by lightning over the oceans. People visiting the coast often say they can ‘smell the ozone’.

The Gteck units use UV light to produce trioxygen in carefully controlled amounts and rates. The extra electron in the oxygen ‘attacks’ odours, grease, mould spores and even smoke damage.

But at the end of the process the O3 simply decays back to normal oxygen (O2). So as well as providing significant cost-saving benefits compared with using traditional, aggressive, chemical cleaning methods, the Gteck system is safe, easy-to-use and environmentally friendly.

Greenteck Global produces a range of units from one small standard electrical socket to provide constant background deodorising to the powerful generator that can be used for ‘shock-treatment’ in a particularly badly affected location.

There is also a Gteck Destruct unit: fully compatible with the generators, it operates automatically at the end of a cleaning cycle to neutralise any unused trioxygen.

In addition to the standard deodorising and sanitising the units can also be installed with – or retro-fitted to – extraction systems in commercial kitchens to degrease and remove cooking odours.

For universities and colleges one of the main uses for trioxygen is in student accommodation. This is especially true at this time of year when cold, wet, weather means the heating is turned up, windows are kept closed, and dirty, wet, clothing is often left piled in corners and so mold and odour are almost perennial problems.

Over the past year Greenteck Global has installed units to universities up and down the country including Cardiff, Leeds, Manchester, Oxford Brookes, Royal Holloway University of London, Falmouth and Optivo Welkin Halls of Residence Eastbourne.

Cardiff uses the plug-in units to control malodour in student rooms. Leeds has now purchased wall-mounted Aura units for a number of stairwells where there were issues with malodour migrating between floors. It also bought the Airteck 1000pd for quick turnaround rooms where malodour is caused by students eating or smoking in rooms. In Manchester, the Aura unit and a Airteck5000p were installed in a corridor directly opposite toilets which led to management offices. Oxford Brookes purchased the AirTeck 10000pd for the main gymnasium, which houses around 30 rowing machines; the university now ozonates the gym overnight to remove malodour and freshen the air space for the following day. Royal Holloway had a major mould issue in a five-bedroom student house. GTG deployed the AirTeck 1664 ozone shock system to remove the problem. Falmouth used a number of plug-in units used for odour control in specific student rooms. Optivo Welkin has a 5000p unit currently on trial for use in old accommodation with mould issues.

David Thurston, founder and head of Greenteck Global, said: “Following on from participating at the CUBO summer conference last July, we have had a fantastic response from a number of universities. Initial site trials have now concluded with our ozone units being deployed permanently.

“Ozone now plays a major part in day-to-day housekeeping regimes and we have proved that ozone is far more effective on all malodour issues from student lifestyle to mould and washroom-related odours.
“We are extremely pleased with the response so far and continue to get fresh enquiries from universities battling with the exact same issues. We continue to support the university sector with our products and services and welcome fresh enquiries to trial our systems.”
