Supported to save: the steel SME cutting carbon and costs

Manchester-based steel fabrication manufacturer, Thos Storey, has saved £49,000, reduced carbon emissions by 243 tonnes and achieved zero waste to landfill thanks to support from ENWORKS.

Thos Storey is a privately owned company that produces and supplies steel fabricated products to a range of customers, from multinational manufacturers to small start-ups. It has an annual turnover of over £12 million and employs 136 staff at its factory site in Openshaw, Manchester.

Environmental impact

Thos Storey holds the ISO 9001 Quality Management Standard and the Carbon Action Standard, and has worked with ENWORKS to reduce their environmental impact since 2007.

It has also identified opportunities to improve its environmental performance independently, having recently improved the efficiency of its spray booth ovens – which are used to add coatings to steel products – by changing shift patterns and optimising oven space.

These changes have cut gas costs by 23 per cent, worth £24,000, and saved 170 tonnes of carbon dioxide equivalent (CO2e).

ENWORKS support

Having carried out a site visit in February this year alongside the Manufacturing Advisory Service (MAS), ENWORKS identified a number of new resource efficiency opportunities for Thos Storey and is now supporting the ongoing implementation process.

Compressed Air

Following ENWORKS’ advice, Thos Storey has replaced its fixed speed drive air compressor with a variable speed drive unit, which will improve machine efficiency and result in a cleaner operational environment.

It is estimated that this change will save £4,000 and 39 tonnes of CO2e a year, with a payback of five years.

Waste disposal

ENWORKS has also supported Thos Storey in changing their waste contract to reduce unnecessary costs and the number of bins onsite.

This has resulted in waste disposal savings of at least £10,000, a 36 per cent reduction.

The new contract ensures that none of the company’s waste goes to landfill, with any non-recyclable waste material transferred to an energy-from-waste facility.

Electricity supply

By analysing the authorised electricity supply capacity to the factory site, ENWORKS was able to save Thos Storey £5,000 by reducing supply capacity by 36 per cent, while still allowing for flexibility to meet customer demands and future expansion needs.


Thos Storey has also begun to implement ENWORKS' recommendation to replace high bay lights on site with energy efficient LEDs.

This move has already saved £6,000 and 34 tonnes CO2e, with £12,000 and 69 tonnes CO2e of further savings still to made as more lights are replaced.

Next steps

Going forward, a number of further resource efficiency improvements have been earmarked for the future.

Along with the continuation of LED lamp replacements, ENWORKS will work with Thos Storey to identify new savings opportunities through compressed air leak detection and thermal imaging surveys, find new outlets for specialist wastes and help progress their environmental strategy.

‘Invaluable resource’

Jo Lynch, commercial director at Thos Storey, said:

“ENWORKS has been an invaluable resource to us. Whilst we strive for continual improvement, this would have proven to be a lot harder without the help, insight and advice from ENWORKS.

“They have provided new ideas and practical advice on ways that we could save both energy and money.”


‘Proactive and responsible’

ENWORKS business advisor, Alasdair Dalzel-Job, said: 


“Thos. Storey Fabrications is a proactive and responsible organisation. Whilst [the above] achievements are impressive, they are constantly looking for ways to improve and I look forward to working with them in the future.”
