CASE STUDY: How trioxygen is cleaning up on campus

A new generation of powerful deodorisers and sanitizers 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 high above the Earth’s surface, 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 (O3) ‘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 and simply enough to plug in to a standard electrical socket to provide constant background deodorising to the powerful 64 g generator that can be used for ‘shock-treatment’ in a particularly badly affected room /location.

There is also a Gteck Destruct unit: fully compatible with the generators; that will operate automatically at the end of a cleaning cycle to neutralise any unused trioxygen.

In addition to the standard deodorising / 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 / halls of residence.  This is especially true at this time of year when cold, wet, weather means the heating is turned up, windows are kept closed, dirty, wet, clothing is often left piled in corners and so mould and odour are almost perennial problems.

Over the past year Greenteck Global has sold / 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 stair wells where there were issues with malodour migrating up stair wells onto other floors, this was, in part, from Mould .They also purchased the Airteck 10000pd unit which they use for quick turnaround rooms where they have malodour caused by students eating , smoking in rooms, plug-in units are also used in student rooms again for background control of living style odours.
  • Manchester – purchased the Aura unit and a Airteck5000p. The Aura unit was installed in a corridor directly opposite toilets where they had a particular difficulty: the corridor leads to management offices so the pungent odour migrated into the main reception area.
  • Oxford Brookes – purchased the AirTeck 10000pd for the main gymnasium. The gym is particularly busy with around 30 rowing machines – Brookes 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 bedroomed student house.  GTG deployed the AirTeck 1664 ozone shock system to remove the mould from five rooms with major mould issues on walls.
  • Falmouth – purchased a number of plug-in units used for odour control in specific student rooms.
  • Optivo Welkin – the site has a 5000p unit currently on trial for use in old accommodation with mould issues.

From Manchester Emily Taylor, Deputy Head of Facilities Management, commented: “The Aura unit really helped us manage the smell from two heavily used toilets in an awkward area: where nothing else we tried eliminated the nasty smells.  Everyone has commented on the genius system.”

While David Thurston, founder and head of Greenteck Global added: “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 a far more affective on all malodour issues from student life-style to mould and wash room related odours.

“We are extremely pleased with the response so far and continue to get fresh enquiries from Universities battling with the extract same issues. We continue to support the university sector with our products and services and welcome fresh enquiries to trial our systems.”

CASE STUDY: The Restaurant Group – Energy Reduction Strategy

By Alan Little, Business Development Manager, ECA Group

The Restaurant Group Plc (TRG) is a significant player in the UK casual dining market, operating over 500 restaurants and pubs which include Frankie and Benny’s, Chiquito, Coast to Coast, Garfunkel’s, Firejacks, Brunning & Price and Joe’s Kitchen.

They also operate a concession business which trades over 60 outlets across more than 30 brands, primarily in UK airports.

One of TRG’s core principals is sustainability and as such a decision was taken in 2013 to implement an energy management programme to reduce wastage across all sites.

ECA manage TRG’s entire portfolio and provide energy procurement, bill validation, compliance and energy management services.

ECA’s Approach

ECA created a strategy to monitor and highlight energy wastage which included regular and detailed consumption analysis, tailored reporting, remote management of exceptions directly with sites, site surveys and behavioural change sessions.

Historic consumption data was analysed against operational hours and other site benchmarks to create profile targets for each meter and site. Monitoring of HH & AMR data on a daily basis using profile usage alarms detected consumption outside targeted thresholds.

These were investigated by speaking directly to site staff to determine the cause and put measures in place to prevent recurrence.

Where a cause could not be established remotely a site survey was arranged to investigate possible causes and rectify issues on site where possible.

Some of the issues that were regularly identified included, broken equipment, misunderstanding of how to use equipment settings for the best effect, and general wastage behaviours such as having equipment on when it is not required.

ECA also attended local and national group events to deliver energy saving tips and advice to TRG staff.

Results

ECA has provided its Virtuous Energy reduction service since 2013 and has achieved year on year savings averaging 5.3% against a target of 2.5%. Last year (2017) we achieved savings of around £500K.

ECA Group – TRG Group Service supplier of the Year

In July this year ECA were awarded service supplier of the year, a fantastic achievement as they were selected from over 100 suppliers.

ECA are still providing this service to TRG and we expect further savings going forwards.

Discover how Sandvik used SAI Global’s EHS solution to drive improvements in their EHS culture

Sandvik were able to implement an EHS solution so robust, that they recently won a Verdantix Innovation Award in 2018.

Like many businesses, Sandvik Mining & Rock Technology had been using spreadsheets to gather and evaluate EHS information and demonstrate compliance. But over time the quantity of interlinked files became unmanageable and the lack of controls left processes open to error. Reporting became time consuming and limited.

Sandvik knew the data held in the spreadsheets was invaluable and recognized the need to utilise the information to drive cultural changes and strategic decision making. But they needed a better solution.

Discover how Sandvik evolved from manual spreadsheet-based processes to SAI Global’s fully-integrated EHS solution in this Customer success story.

The results and efficiencies speak for themselves and it’s clear to see why this project saw them recognised by independent analysts as a winner of a Verdantix HSE innovation award.

CASE STUDY: UBS achieves award-winning energy savings

ebm-papst recently completed a project for UBM that has delivered energy savings of 10,657MWh – Here’s how those savings were achieved…

Project Overview

UBS operates a 130,000 sq ft data centre in west London which is fundamental to the operation of the firm’s global banking systems. Within this site there were a number of misson critical Down Flow Units (DFUs) operating around the clock to sustain the required operating conditions for the computer equipment in the data centre.

The Fans

ebm-papst replaced the existing Down Flow Units in the data centre with high efficiency direct drive EC fans in the computer room air conditioning (CRAC) units. UBSs objective for the project was to reduce the drawn-down power by up to 30%, resulting in a 180kW power reduction load to be allocated to IT equipment.

The Project

The challenge was to improve the energy efficiency of the data centre, freeing up additional electrical capacity to use on IT resource. In addition, our task was to improve the airflow and improve controllability of the cooling units in the data hall.

Typically heating, ventilation and air conditioning (HVAC) systems can be responsible for over half the energy consumed by data centres. In cases where energy is limited, improving the energy efficiency of HVAC equipment will result in a more improved allocation of energy resource to IT equipment.

The Results

The solution resulted in a load reduction of 250 kW against a target of 180 kW. This resulted in an annual power saving of 48%, which allowed UBS to increase IT power consumption in addition to reducing CO2 emissions and energy costs.

Over the past 4 years and 10 months since the project took place (as of March 2017), UBS has achieved:

  • 191 fans installed
  • 76 CRAC units upgraded
  • 3 different models installed
  • Energy savings -10,657MWh (4 years and 10 months)
  • Financial savings – £667,836 after payback of total install costs

(payback period of 23 months)
