WORLD ENERGY SAVING DAY 2025

🌍 The world doesn’t stop — and neither do we!

Once again, we celebrate #WorldEnergySavingDay as it should be celebrated: by contributing our part so that, together, we can make our daily activities as sustainable as possible.

We would especially like to highlight that four years have now passed since the installation and commissioning of an Energy Saving System for an island of 4× MÜLLER WEINGARTEN MW2800 presses, where the savings achieved have exceeded — and continue to exceed every working day — 50% compared to the consumption before our intervention.

If we add this achievement to all the others accomplished since 2016, across more than 32 machines, the figures are truly impressive:

💰 Energy savings for our customers of 8.87 GWh!!! (8,870,000 kWh)
💨 More than 3,900 tons of CO₂ NOT emitted into the atmosphere

🧐 Let’s take a moment to think about the energy generated by an average wind turbine, like the ones we see on our mountains: approximately 2,000 kWh.

If a wind farm has, for example, 20 turbines, this means we have saved the equivalent energy that those turbines would generate over more than 440 days — more than 1.2 years.

Energy that could be:

– Used for other needs
– Used to delay the installation of new wind farms
– …

And you, what would you do with all that energy?

As we do every year, we like to take stock of the savings achieved for our customers thanks to HREGreen solutions.

We have recently finished implementing the solution to a customer who has achieved 48% energy savings on his new machine.

And since 2016, which we have been keeping track, the impressive result is that:
We have helped our customers achieve cumulative savings of 7.15 GW/h, that is, more than 3,300 tons of CO₂ not emitted into the atmosphere!

One liter of water at 25 ºC we know is capable of absorbing approximately 1.5 grams of CO₂.
Thinking that the average consumption in the state is about 55,000 liters of water per person per year, the amount of CO₂ saved would be equivalent to the volume corresponding to the annual water consumption of 40,000 people.

That’s quite something, isn’t it? And without realizing it – because we have already internalized these savings – we are once again helping to achieve a healthier ecosystem and a greener planet, supported by the levers of sustainability, eco-innovation and eco-design.

Of course, we must add the more than favorable economic impact that these savings represent for our customers’ finances, and therefore for their bottom line.

At HRE Automation, we have experienced a moment which fills us with emotion: our BeCold project has been awarded at the Advanced Manufacturing Awards 2024 as being the best in sustainability and circular economy. This recognition, awarded at IFEMA Madrid, during the MetalMadrid fair, highlights the impact of our innovation in the industrial transformation towards a more sustainable future.

This achievement would not have been possible without the collaboration between TECNALIA Research & Innovation, the UPV/EHU and HRE Automation, which made this revolutionary patent a reality. Special thanks to José Ángel Alberdi, the “alma mater” of this project, whose vision has made it possible to offer a sustainable alternative to traditional machining.

We would like to thank the jury: Antonio de la Presilla, Antton Meléndez Arranz, Carlos González, Eva García Biosca, Gala Maturana, Juan Miguel Poyatos Díaz, Juan Ramón Marijuán Q., Nerea Ordás, Núria Salán, Pedro Romero and Xoan Xosé Fernández Sánchez-Romate, and all those who have supported us with their votes.

We also thank the sponsors EMKA Beschlagteile and CARBUROS METÁLICOS, and the supporting partners: HispaRob, Izaro Manufacturing Technology, VALMETAL, HEGAN – Basque Aerospace Cluster, EIT Manufacturing, 3d-native.com, COIT AEIT and FEMEVAL.

BeCold, our sustainable machining solution, has crossed borders and is already established in international markets, including Japan!

Through Minimum Quantity Lubrication (MQL) and the use of CO₂, we are revolutionizing the machining of difficult-to-machine materials. This technology is not only more sustainable, but also allows us to optimize resources and achieve significant economic savings.

BeCold is not just an innovative technology; it is a reflection of the effort, dedication and vision of the HRE team, which proves every day that together we can transform the industry and build a more responsible future.

Congratulations to the other winners! It is an honor to share the stage with such inspiring projects.

From HRE, we will continue to work with the same passion and commitment, because we firmly believe that every step we take can make a difference.

Through the collaboration of leading academic institutions and industry leaders, such as the University of the Basque Country (UPV/EHU), Tecnalia and the support of Nippon Gases, innovative tests have been carried out under the HAZITEK BERMEK project, which have yielded extraordinary results.

In these tests, the revolutionary BeCold System has been used together with CryoMQL technology for milling stainless steel. The results obtained have been a resounding success, marking a significant breakthrough in the industry.

This effective collaboration between academia and industry is a testament to our commitment to innovation and technological development.

We are proud to be part of this exciting project and to witness the excellent results that have been achieved.

On 21 November 2023, the Royal Academy of Engineering awarded the outstanding Juan López de Peñalver Prize to Amaia Calleja Ochoa, Industrial Mechanical Engineer at the University of the Basque Country and current full professor at the same institution. This prestigious award, intended for people under the age of 40 who have excelled in Spanish engineering, celebrates the work of Amaia and her team at the Aeronautical Advanced Manufacturing Centre.

Amaia Calleja Ochoa headed the group made up of engineers Haizea González and Izaro Ayesta, as well as engineers Adrián Rodríguez and Octavio Pereira. Their contribution focuses on the development of an innovative cryogenic cooling technology with recycled CO2, used as a cutting fluid in machining processes. This breakthrough, known as BeCold, has managed to replace polluting cutting oils, generating improvements in both productivity and the environment.

Amaia Calleja Ochoa expressed her gratitude to HRE for trusting in the product, highlighting the patent and the team’s research dedication over the years. The BeCold technology has been successfully industrialised and marketed in countries such as Japan, Poland and Canada, demonstrating the commitment of Amaia and her team to innovation and sustainability in engineering.

At the recent 19th edition of the Global Conference for Sustainable Manufacturing, the Centre for Advanced Aeronautical Manufacturing (CFAA) presented the results of its pioneering research focused on the eco-sustainable improvement of super duplex stainless steel turning. The key to this breakthrough lies in the application of the CRYOMQL technique.

The findings revealed that the CRYOMQL technique not only optimises the turning process, but also significantly extends the service life of the tool used. This extension in tool efficiency leads to an overall improvement in the sustainability of the manufacturing process, highlighting a further step towards more environmentally friendly practices.

The achievement of the CFAA not only has positive implications for the aerospace industry, but also demonstrates how the implementation of sustainable technologies can effectively reduce the environmental impact of manufacturing, while promoting efficiency and product quality.

In this context, HRE Automation is proud to contribute to this revolution in sustainable manufacturing. By supplying specialised BeCold Cryogenic Machining equipment, HRE Automation positions itself as a key partner in the adoption of advanced and environmentally friendly technologies.

As it could not be otherwise, this year we have also been present in the different activities for the commemoration of World Energy Saving Day, which was celebrated on 21 October 2023.

In line with the values of HRE Automation, Circular Economy and Green Design and Manufacturing, and thanks among other applications to the implementation of our energy efficiency system, we have continued to make progress in reducing the carbon footprint and electricity consumption of our customers by between 35% and 50%.

Having started the different programmes in 2016 and to date, we have managed to save a total of 5.84 GW/h, which is the same as 5,840,000 KW/h for our customers. This means that more than 2,700 tonnes of CO₂ have been saved from being emitted into the atmosphere.

This value is equivalent to the planting of 16,225 trees, which would be necessary to absorb the carbon dioxide saved by our processes. With a standard density of 200 trees per hectare, we save the space that would occupy more than 81 hectares, which is 810,000 m².

Looking at it another way, now that olive oil is almost prohibitively expensive:

If we consider that one hectare of olive tree cultivation yields about 5,000 kg of olives, with these 81 hectares saved we could obtain about 405,000 kg of olives, which would be equivalent to about 81,000 L of EVOO. The equivalent of the annual oil consumption of 12,000 people. Surprised?
