Shape e-Waste into Sustainable Tech Solutions this Earth Day and Beyond

In today’s world, electronic devices are essential, improving our lives and connecting us like never before. While this digital evolution has brought about incredible advancements and conveniences, it also presents the challenge of managing electronic waste (e-waste) generated by digital lives.  By Alex Rice, Field Product Manager at Dell Technologies

Today, as we mark Earth Day, we’re once again reminded of the urgency that technological innovation and the need to protect the planet must go hand-in-hand by embracing sustainable solutions and responsible recycling. we can enjoy the benefits of technology while safeguarding the environment for future generations.

The European Union, a global leader in environmental policy, finds itself grappling with the issue of e-waste. According to the UN, e-waste volumes are growing five times faster than e-waste recycling, with an 82% jump since 2010.

The European Commission’s circular economy action plan offers a glimmer of hope with its promotion of repair and reuse initiatives. However, businesses in Ireland that are expected to be part of the solution are often caught between regulatory pressures, financial constraints, and evolving consumer demands.

For Irish business decision makers often the question is how can we reconcile the pressing need to innovate and remain competitive while being environmentally responsible?

Thankfully, the answer is not about choosing one or the other. Instead, it lies in reimagining our relationship with technology and embracing an end-to-end approach to sustainability: where resources are valued, products are designed with sustainable materials and waste is minimised.

 

1. Smarter product design to promote circularity

Product design plays a significant role in reducing waste and thinking about how to reduce production costs in the long-term. A sustainable approach begins with creating guidelines for how components are designed before they go on to form complete systems.

Product design dictates how practical it is to reuse and refurbish these components or to harvest recyclable materials at the end of a device’s life. Designing with durability and modularity in mind means that parts can come back through a services network before re-entering the supply chain, to be used to repair and refurbish systems. For customers and consumers, there is the added benefit of being able to purchase these products at a lower price point.

For components that cannot be easily reused, manufacturers should focus on easy disassembly paired with clear markings, minimised paintings and coatings and simplified material choice. This makes it easier for the recycling industry to recover more material, more quickly.

2. Design with circularity in mind

Information technology is heavily dependent on finite raw materials, including minerals like lithium or cobalt, which are associated with high energy, water consumption and environmental damage during extraction.

For example, at Dell, we design our products for easy repair, reuse, and recycling at end-of-life to keep products and materials in circulation for longer to help reduce pressure on resources and prevent waste. We use recycled and/or renewable materials from innovative sources to help lower the environmental impact of our products and packaging. Every pound of steel, aluminium, plastic and copper that we recover is a pound of material that doesn’t have to be extracted from the ground.

Demand for alternatives is increasing, particularly as they do not deplete additional natural resources and emit fewer greenhouse gases in their production and during the product life cycle. For example, low emissions aluminium and recycled cobalt are being used in our AI PCs. Another alternative material is a bioplastic derived from the production of paper, which is used as new component for technology casings.

One of the most immediate initiatives is for the IT design process to operate as a closed loop model, which keeps products and materials in circulation as long as possible.

3. Harnessing AI for sustainable innovation

AI presents a transformative opportunity to help Irish businesses meet broader sustainability objectives. AI can help solve complex environmental issues but it’s crucial to balance this with ensuring that the AI model and infrastructure itself has strong sustainability credentials. However, six in 10 customers think AI will compromise their environmental sustainability efforts, and many customers are not sure where to focus.

The opportunity for leveraging AI as a tool lies in its ability to identify issues more efficiently around sustainability, meaning they can be addressed more promptly. By analysing vast amounts of data from various sources, AI can identify fixes quickly than alternatives. The insights derived are useful for informing strategies that reduce waste across everything from the supply chain itself, through to manufacturing and packaging optimisation.

Reducing energy consumption and e-waste within AI requires a multi-faceted approach, including embracing energy-efficient hardware like low-power processors and accelerators which can significantly shrink carbon footprints. For example, our sustainable data centre solutions like storage and servers built with leading liquid and air cooling, emissions tracking and energy efficiency top being top of mind. Therefore, consideration about the modular design and upgradeability of AI hardware can minimise the e-waste coming out of the infrastructure needed to power the models.

4. A holistic end-to-end approach

Because sustainability is now a business imperative, businesses here in Ireland should embed it through every stage of business operations. Responsible practices should be integrated into every facet of the organisation, extending outwards to suppliers, partners, and customers. Having clear, internal, and external alignment on these goals makes it easier to drive more sustainable materials innovation, pioneer new energy solutions and navigate changing regulatory landscapes.

Cross-functional collaboration is key to empowering change within the whole ecosystem; for instance, if it becomes a requirement that products need to be designed with materials innovation at heart, then suppliers are challenged to innovate to meet those specific demands.

Take action this Earth Day The digital revolution has reshaped our world and created new economic opportunities; it’s the environmental impact that can’t be ignored; nor can it continue in the same way.

The escalating e-waste crisis calls for a shift in the way we approach building and designing new technologies.

As we mark Earth Day 2025, it’s time to embrace circularity, resource efficiency and employ longer-term thinking when it comes to technological innovation. By exploring new ways of thinking, businesses can begin shaping a digital future that strives to grow in balance with the environment, creating opportunities for both progress and sustainability.

Virtual Reality in Education: The Future of Learning Right Ahead

Virtual reality (VR) has gone from the domain of science fiction into the mainstream in recent years, transforming sectors including entertainment to healthcare. Its ability to revolutionize education is now acquiring impetus.

VR is revolutionizing schools and teachers especially in science education as they search for creative approaches to involve digital-native students and close the theory-practice gap.

Outline virtual reality and explain its applications.

Virtual reality is the simulated experience that might be either exactly like or quite different from the real world. Usually, it uses a headgear that envelops the user in a 3D environment so enabling real-time interaction with digital elements.

Users can experience scenarios from a first-person point of view, move across the surroundings, and handle objects.

VR is already rather extensively applied outside of the classroom. Medical students perform procedures in virtual operating rooms in hospitals. In architecture, designers stroll through virtual building models before they are ever built.

Gamers enter large virtual worlds with lifelike graphics and physics in entertainment. All of these programs have as their common thread immersion and interactivity—qualities that can be quite effective in the classroom.

Why Virtual Reality in Education Might Be the Next Frontier

Virtual reality in education marks a major change in the way teachers present materials and students absorb knowledge. Lectures, textbooks, and sporadic hands-on exercises define conventional classroom environments.

Although these strategies have many benefits, they can find it difficult to involve students completely, particularly in relation to abstract or difficult topics including chemistry, physics, or biology. VR presents a chance to bring learning more physical and interactive.

Imagine students seeing real-time oxygen-rich blood flow across arteries as they investigate the human circulatory system from the inside. Alternatively, chemistry students working in a totally safe digital lab on perhaps hazardous reactions.

Deeper knowledge and long-term memory depend on VR transforming students from passive receivers into active participants.

 

Benefits of VR in Education

Using virtual reality in classrooms offers many benefits. Among the most convincing advantages of VR are its capacity to support active learning, increase participation, and produce unforgettable learning opportunities. Here are a few main advantages:

1. Enhanced Involvement and Motivation

Students that participate actively in their education are more likely to remain involved. VR brings an exciting quality absent from many conventional approaches. Using cutting-edge technology in conjunction with immersive storytelling and interactive surroundings makes courses unforgettable and fun.

2. Enhanced Conceptual Knowledge

Like molecular structures, gravitational forces, or electromagnetic fields, abstract ideas are famously challenging to teach. Often directly manipulating these ideas, VR lets students see them in three dimensions. This spatial interaction makes learning more natural and helps one to grasp.

3. Safe and Understood Environment

Many experiments in disciplines including chemistry or physics include hazards that restrict active student participation. In a real-world classroom, VR lets students run experiments that would be too costly, dangerous, or logistically difficult. Errors become inevitable in the course of learning without any practical repercussions.

4. Individualized Education

One can create VR systems to fit different learning environments by means of design. Immersion graphics help visual learners; kinesthetic learners value interactive simulations. Some sites even provide real-time comments to help students through courses at their own speed.

5. Inclusiveness and Accessibility

VR can provide experiences otherwise unattainable for students with disabilities or those living in remote areas. Virtual field trips, 3D visualizations, and simulated labs help to level the playing field and offer equal learning possibilities.

Useful VR Applications for Science Education

There is nowhere more clear the influence of VR than in STEM education, especially science. These are a few useful approaches VR is now being used in science classrooms:

1. Virtual laboratories for science

Creating virtual labs where students may conduct experiments without using actual materials is one of the most efficient applications of VR. Under a VR helmet, platforms like Futuclass—which provides modules allowing students to balance chemical equations, mix elements to form compounds, or see exothermic reactions—offer These labs provide hands-on experience that supports theoretical knowledge by simulating real-world physics and chemical interactions.

2. Human Biography and Anatomy

Students could investigate the human body in 3D rather than learning diagrams from a textbook by memory. Learners can “walk through” organs, see body processes in action, and even replicate surgical operations using virtual reality. Higher education and medical training, where a better knowledge of anatomy is crucial, benefit especially from this approach.

3. Physics Replays

From grasping Newton’s laws to experimenting with electromagnetism, VR lets students visualize forces, motion, and energy transfer in ways that would be challenging in a conventional lab. Students can, for instance, instantly see how changes in variables like gravity or friction affect outcomes—something impossible in a real-world classroom. This allows them to control those variables.

4. Environmental and Earth Sciences

In environmental science education VR is also creating waves. Students might investigate several ecosystems, see how climate change is affecting things, or go through geological events like earthquakes or volcanic eruptions. These immersive events inspire closer involvement by making world problems feel instantaneous and personal.

5. Discovery of Space

 Virtual reality lets students travel across the solar system, land on Mars, or negotiate the International Space Station, so transforming their lessons in astronomy. This not only piques interest but also helps to place difficult astrophysical ideas in a context never possible in textbooks.

Using VR in Education: What More Is Needed?

Although the advantages are obvious, using VR in learning environments does call careful preparation:

  • Schools need VR headsets, ideally with high-resolution displays and easy controls. Affordable choices for classroom use are Meta Quest, which provides wireless, stand-alone capability.

     
  • Software and Content: Excellent learning materials are absolutely vital. Curriculum-aligned VR modules especially meant for middle and high school students are offered by external providers.

     
  • Teachers have to be at ease using VR technology and including it into their lessons. Many companies provide onboarding and support to guarantee seamless adoption.

     
  • Important factors also include infrastructure: charging stations, a stable Wi-Fi connection, and an area where students might safely use VR headsets.

     
  • Safety and Monitoring: Schools should create procedures for supervised use, so guaranteeing that sessions are catered to avoid motion sickness or disorientation and that students use the equipment responsibly.

     

Last Words

Virtual reality in education offers a present-day chance to rethink how we teach and learn, not a futuristic dream. The possibilities to create interesting, significant, and successful learning environments become almost endless as more universities embrace immersive technologies.

Particularly in science education, VR provides a strong means to bring abstract ideas to life, so enabling students to investigate, experiment, and really comprehend the surroundings.

Investing in this transforming technology now will help teachers equip their students for the real-world challenges of tomorrow rather than only for tests.

Irish research group DIAS involved in world first lunar-Earth flyby

A team of three researchers from the Dublin Institute for Advanced Studies (DIAS) will play a key role in the first ever spacecraft attempt to fly past the Moon, and then past Earth.  The flyby is set to take place over tomorrow and Tuesday (19-20 August).

The manoeuvre is part of the European Space Agency (ESA)’s Jupiter Icy Moons Explorer (JUICE) mission. As well as conducting detailed observations of Jupiter and its moons, the mission will be investigating Jupiter’s moons as possible habitats for life.

The lunar-Earth flyby will be an opportunity for the DIAS team to test their ideas about the spacecraft’s behaviour in the environment of a moon, in preparation for the actual flybys of Jupiter’s moons.

Senior Professor Caitriona Jackman, Dr. Mika Holmberg and Dr. Hans Huybrighs are all members of the DIAS Planetary Magnetospheres Group, which is the only Irish research group involved in the mission.

Commenting on DIAS’s role in the flyby, Prof. Caitriona Jackman, Associated Scientist and Head of the Planetary Magnetospheres Research Group at DIAS, said “We will be monitoring the flyby with trepidation as it’s an extremely challenging undertaking – the slightest mistake could take Juice off course and spell the end of the mission.

“This is the first step in Juice’s journey through the solar system on its way to Jupiter. The spacecraft will use the gravity of the Moon and then Earth to bend its path through space and redirect it on course for a flyby of Venus in August 2025. This will help to ensure it arrives at Jupiter with the right speed and direction. It’s a journey that requires perfect accuracy and in-depth planning.”

“Having this opportunity to test our ideas about the spacecraft’s behaviour in the environment of a moon is truly exciting and will be a huge boost in confidence for our research once Juice arrives at Jupiter. The encounter of Earth’s moon is a practice-run for when we get to Jupiter, where we will study moons with underground oceans that might support life. I’m extremely proud of the work carried out by our research group so far, and that we can be part of such an important mission.”

DIAS expertise

DIAS’s work on this mission will explore how the spacecraft itself affects the measurement of particles, and will use an advanced computer model to investigate this. Commenting on her involvement in this mission, Dr. Mika Holmberg, Research Fellow at DIAS and Co-Investigator on the Radio and Plasma Wave Investigation Instrument, said “The measurements from the lunar-Earth flyby could have a significant impact on our research going forward. The effects of the interaction between the spacecraft and its environment influences our interpretation of the measurements. For example, it might change our understanding of where the moon particles that we are trying to detect come from, or how many there are.

“The computer simulations account for the environment of the spacecraft and models how the moon particles will be affected, so that we can correct potential misleading effects for later in the mission. When Juice flies by the Moon we have the first opportunity to test our correction techniques during an actual moon encounter, which is exciting. It’s the perfect opportunity for us to calibrate our instruments and smooth out any remaining issues, and who knows what it could lead to!”

Dr Hans Huybrighs, Research Fellow at DIAS and Associated Scientist of the Particle Environment Package instrument explains that the main objectives of the mission are to study the abilities of Jupiter’s moons to host life, which requires accurate and detailed measurements. “Jupiter’s moons slowly release particles from their surface. In some cases, this release could happen through water eruptions that produce 100-kilometre-tall plumes. By detecting these particles, we can learn more about the moons’ potential to support life. Investigating how Juice can best detect these plumes is one of the topics we are working on at DIAS.”

DIAS as a leader in space research

Commenting on DIAS’s role in space research, Dr. Eucharia Meehan, CEO and Registrar of DIAS said, “It’s fascinating to follow the spacecraft’s journey through the solar system with incredibly complex manoeuvres. Scientists around the world have been carefully planning this route over the last 20 years and it’s a huge honour that DIAS is playing a role in this mission. This flyby is hugely important as it’s one of the few opportunities to make certain measurements and adjustments during Juice’s eight-year journey to Jupiter.

“DIAS has a long history in being at the forefront of Ireland’s involvement in cutting-edge space research with the James Webb Space Telescope, and now our contribution to the Juice mission. We have been following Juice’s progress closely since its launch in April 2023. We are very proud of the work of our researchers, and we are looking forward to updates on the progress of the flyby.”

The Juice mission is being led by the European Space Agency, of which Ireland is a member state. 18 different research institutes, 23 countries, 83 different companies and more than 2000 people have contributed to the mission.

DIAS’ work on this mission is funded by Science Foundation Ireland and a European Space Agency fellowship held by Dr. Mika Holmberg. Further Information about DIAS’ involvement in the Juice mission can be found here: https://www.dias.ie/cosmicphysics/astrophysics/astro-Juice/

Advanced computer simulations shed intriguing new light on magma deep below Earth’s surface

Unlike the classic Jules Verne science fiction novel Journey to the Center of the Earth or movie The Core, humans cannot venture into the Earth’s interior beyond a few kilometres of its surface. But thanks to latest advances in computer modelling, an international team of researchers led by the University of Bristol has shed new light on the properties and behaviour of magma found several hundreds of kilometres deep within the Earth.

The study showed water-rich (hydrous) magmas (extremely hot liquid rocks) formed in the Earth’s mantle – the layer beneath its crust – are more buoyant and fluid than previously believed. This discovery allows us to predict how and where hydrous magmas move within Earth’s interior, which means the amount of water in these realms can be more reliably predicted, furthering understanding of the deep Earth water cycle.

Lead author Dr James Drewitt, Senior Research Associate at the University of Bristol, said: “It’s really exciting to be able to explore the nature and properties of magma hundreds of kilometres beneath our feet. Although previous knowledge is limited, it was widely thought these water-rich molten rocks, called hydrous magma, would be denser than the solid rock above them and so would form vast pools of magma at depths close to 400km.

“However, we were not convinced by this theory, as it relies on chemical compositions which are unrepresentative of natural magmas, as known from high-pressure laboratory experiments. We wanted to determine the properties of hydrous magmas to model their behaviour, how they flow and where they go after forming in the deep mantle, to provide more accurate insight into the deep Earth water cycle, which is tightly connected to Earth’s habitability.”

The researchers used ARCHER, the UK’s national supercomputing service, to simulate the physical properties of magma at the extreme conditions on the boundary of Earth’s upper and lower mantle at temperatures up to 1600°C and 250,000 times atmospheric pressureThis region, at depths of 410-660km, is known as the transition zone and contains solid rocks capable of storing several ocean’s worth of water.

The high water content means rocks just above and below the transition zone will melt at a lower temperature than elsewhere in the Earth’s mantle, resulting in the formation of water-rich or ‘hydrous’ magmas. Their physical properties, including density and viscosity – in other words how freely they flow – have been shrouded in mystery, so little was known about how they behave and where they ultimately go.

 

Dr Drewitt said: “Using advanced computational techniques to model hydrous magmas down to the atomic-scale, we discovered natural hydrous magmas will be more buoyant and fluid than expected, and will therefore rise through the upper mantle towards the surface, rather like the wax rising in a lava lamp.

“By incorporating these findings into global mantle circulation models, we found that over geological timescales water in hydrous magmas was transported from the lower and mid-mantle towards the upper mantle, resulting in a similar mass of water found in all Earth’s oceans combined evenly distributed throughout the mantle of the present-day Earth.”

The three-year-long study, funded by the UK’s Natural Environment Research Council, involved physicists and Earth scientists from universities in the UK, United States, and China.
