From paper to pasta: Industrial heat pumps have the power to cut 25% of EU manufacturing emissions
The EU's industry could cut a quarter of its CO2 emissions using heat pumps, according to the European Heat Pump Association (EHPA).
If the heat pump technology available today was fully rolled out, the association says it could already supply 37 per cent of the industry's process heat - thermal energy used in industrial manufacturing processes.
This rollout would see Europe's industrial sector save up to 146 million tonnes of CO2 annually or 24 per cent of its current emissions. That is a saving bigger than the annual emissions of Czechia.
'Europe needs competitive and sustainable industry - and large-scale heat pumps are key,' explains Paul Kenny, EHPA Director General.
'The technology is already delivering reliable heat, cost savings and affordable energy in manufacturing processes from paper to pasta, and this can and must increase.'
What manufacturing processes can industrial heat pumps be used for?
More than 60 per cent of the energy used by European industry is used for heat, according to the EPHA. The bulk of this demand (66 per cent) for heat comes from process heating or the use of thermal energy in manufacturing.
Almost 80 per cent of this energy traditionally comes from fossil fuels. Currently, just 3 per cent comes from renewable electricity and 11 per cent from biomass. Decarbonising heat energy requirements by 2050 is a priority to meet current EU emissions targets.
Industrial heat pumps can reach temperatures of up to 200C, which means they can be used for processes that require lower temperatures. Of the total heat energy demand from process heat, 37 per cent is from manufacturing that requires temperatures lower than 200C.
That includes things like brewing beer, dairy processing, and paper manufacturing. The Wepa Greenfield paper factory in Château-Thierry in France, for example, uses a heat pump to dry paper pulp. A project partially funded by the French government sees 70C waste heat from the dryer converted into 140C by a heat pump - enough to dry the paper pulp.
Why aren't companies already using heat pumps?
While around 16 per cent of heating in the EU's residential and commercial buildings now comes from heat pumps, there's currently no comprehensive data on how many companies have adopted the technology for industrial processes.
There are still a number of barriers to increasing heat pump uptake - including a lack of awareness about their potential. Upfront costs, too, can prevent companies from switching.
Nearly all European countries offer financial subsidies or support for companies that want to invest in an industrial-sized heat pump. A survey by EPHA found that among 24 EU states - including Norway and Switzerland - help is available in the form of grants, loans, or tax rebates.
The EU's proposed Industrial Decarbonisation Accelerator Act aims to speed up the decarbonisation of energy-intensive industries. It wants to do this by streamlining procedures for clean tech permits, facilitating investment in cleaner solutions, and supporting the development of green markets.
The EPHA believes more focus should be placed on research, regulation and information sharing to ensure heat pumps are a key part of this plan.

Italy forges on with world's largest suspension bridge
The 13.5-billion-euro ($15.3-billion) project would carry trains and six lanes of traffic, allowing cars to cross the Strait of Messina in 15 minutes. Giorgia Meloni's hard-right government hopes to boost the economy of the impoverished region, although critics say there are better ways to do this -- and many believe that after decades of false starts, the bridge will never actually happen. The choppy waters between the eastern tip of Sicily and the western edge of the region of Calabria are legendary as the place where monsters Scylla and Charybdis terrified sailors in Homer's epic poem "The Odyssey". These days the challenges are more prosaic, from winds of more than 100 kilometres an hour (62 mph) to the real risk of earthquakes in a region that lies across two tectonic plates. The government says the bridge will be at the cutting edge of engineering, with the section suspended between its two pillars stretching 3.3 kilometres, the longest in the world. But critics point to a long history of public works announced, financed and never completed in Italy, whether due to corruption or political instability, resulting in enormous losses for taxpayers. "The public does not trust this political class and these projects that become endless construction sites," said Luigi Storniolo, a member of protest group No Ponte (No Bridge). Infrastructure Minister and Deputy Prime Minister Matteo Salvini, one of the main champions of the project, insists it will be a game-changer for the local economy. "The bridge will be a catalyst for development," he said on a recent visit to Reggio di Calabria, the city where the bridge will begin. 'A senseless project' The government hopes to boost trade in Sicily, which currently suffers from an "insularity cost" of around 6.5 billion euros a year, according to regional authorities. Meloni's ministers are expected to give their final approval to the project -- which Rome will fund -- later this month, and Salvini insists construction will begin this summer. But work had already been announced for the summer of 2024, before being postponed -- a common theme in the history of the bridge, the idea of which dates back to the unification of Italy at the end of the 19th century. The first law for the project was passed in 1971. Since then, successive governments have either revived it or cancelled it. In 2012, the idea appeared to be definitely abandoned amid the eurozone debt crisis, only for Meloni's government, which took office in 2022, to return to it once again. Salvini has repeatedly stated that the bridge would create 120,000 jobs in Calabria and Sicily, which have the fourth and the 13th highest unemployment rates respectively in the EU for young people under 29. However, the left-wing CGIL trade union estimates around 2,300 workers a year will be hired during the project, and critics say the jobs created will be offset by long-term losses from the closure of ferries. Mafia risk The project has sparked local protests, with critics warning of the impact on a protected marine zone and an important bird migratory route. Storniolo told AFP it was a "senseless project" which used up valuable funds when "our regions already suffer from many problems... healthcare, schools, and infrastructure." The Italian Court of Auditors has also criticised the extent of the debt-laden Italian state's investment in this one project in its assessment of the 2024 budget. "They want to make an entire territory believe that its only hope is this bridge -- but then the bridge never arrives," protester Storniolo added. There is also the question of mafia infiltration. The attorney general of Messina recently warned of the risk that organised crime would benefit from the project, noting that "the power of the mafia is hidden... behind public contracts". The government has proposed placing companies relating to the project under control of an anti-mafia structure reporting to the interior ministry. But Italian President Sergio Mattarella blocked this, saying it should only be used for one-off events such as earthquakes or the Olympics. Salvini argued that the bridge can help tackle the mafia, saying: "You do not fight the mafia... with conferences and protests, but by creating jobs and giving hope to young people."

Mental health innovations take centre stage at VivaTech Paris
VivaTech opened its doors this Wednesday in Paris, marking the start of Europe's most important tech and startup annual event. With more than 165,000 expected visitors and nearly 14,000 startups from over 50 countries, the ninth edition of the event is set to be the biggest yet. Just like last year, artificial intelligence (AI) is the star of the show. But this time, some of the most attention-grabbing innovations are those applying AI and tech to health care and mental well-being. 'Artificial intelligence is moving from science fiction to real-life application. And visitors will discover with the more than 13,000 start-ups what it is going to mean for business, for our everyday lives and our democracies," said François Bitouzet, Director General of VivaTech. There is a geopolitical context that is incredible in which tech and AI play a role, and we will analyse this during the next four days," he told Euronews. In a year marked by increasing geopolitical tensions and debates around technological sovereignty, Europe is looking to assert itself as a key player in AI innovation. But the tech fair also serves as a platform to explore how this technology can help address deeply human challenges. One such example is Emobot, a French startup developing an AI-powered tool that helps monitor mood disorders through a patient's facial expressions and voice. 'It's an app that is installed on the phone and on the computer. We analyse facial expressions every second while the patient uses their phone throughout the day," explained Antony Perzo, co-founder and CTO of Emobot. "We also analyse their voice. Then, we aggregate this data to monitor for symptoms of depression. All this data, we put it together and then make a dashboard for the doctor that allows them to follow the evolution of the mood disorder symptoms," he told Euronews. All this information is combined to generate a dashboard for doctors, allowing them to track the evolution of symptoms remotely. 'Psychiatry is one of the few disciplines where we can't visualise disorders. In other areas of medicine, we have MRIs or imaging tools. We wanted to create the first device capable of tracking and visualising mood symptoms over time. Think of it as a sort of thermometer for mental health', he said. Another mental health startup, AMOI, blends neuroscience with perfume to shift a person's mood in just minutes. Whether you're looking for focus, calm, energy or joy, AMOI claims its neuro-fragrances can deliver results within five minutes. With more than one in four people reporting feeling mentally unwell, AMOI's founder Pascale Fontaine, says her project is about offering accessible and enjoyable tools for emotional well-being. VivaTech runs until 14 June at the Porte de Versailles exhibition centre in Paris. The European debate on children's access to social media networks has begun, with three EU Member States promoting the idea of a "digital majority" or the age below which it would be forbidden to connect to such platforms. For France, Spain and Greece, the goal is to protect minors from dangerous online content. "Today, in the terms and conditions of use of these platforms, there is already a minimum age of 13," explains Clara Chappaz, the French Minister Delegate for Artificial Intelligence and the Digital Economy. However, Chappaz says: "We've all been children, it's very easy to change your date of birth. And so the current system means that, on average, children are logging on and creating accounts from the age of 7-8." France, Spain and Greece believe that the algorithms used by social networks expose the very young to addictive content that can ultimately lead to increased anxiety or depression. They also argue that excessive exposure may limit the development of certain skills and impair cognitive abilities. The EU currently has legislation in place in the form of the Digital Services Act (DSA), which tackles illegal online content such as hate speech, terrorism and child pornography. The law has been in place for almost two years for larger platforms and search engines, and just over a year for smaller organisations. But for industry representatives in Brussels, new legislation appears premature. "We believe that the new rules must first be properly applied. We haven't yet seen all the effects," says Constantin Gissler, Managing Director of Dot Europe, which represents online services and platforms in Brussels. "I think it's a bit hasty at this stage to be already discussing new rules and I think it's also very important that we take more account of the reality and implications for minors of such a ban," he adds. Paris, Madrid and Athens are also proposing the integration of age verification and parental control systems for devices connected to the Internet. The European Commission is currently working on an age verification application. Last month it published draft guidelines to protect minors, such as measures to verify the age of users or to set children's accounts as private by default. It is also conducting investigations against TikTok, Instagram and Facebook in relation to the protection of minors.

French Senate approves ‘anti-fast-fashion' bill chiefly targeting Shein, Temu
Louwagie said that the government will notify the European Commission of this bill even before the end of the joint parliamentary committee work that will start soon, and that the government will also work on the decrees regulating the bill's application, and notably define the thresholds that will formally identify an operator as 'ultra-express' or 'ultra-fast-fashion'. Before the vote, the representatives of the various Senate groups spoke to explain their positions on the vote. An opportunity to underline for some the positive amendments made to the bill, and its weaknesses for others. Many senators welcomed the removal of a provision of the 2022 anti-waste law on unsold goods, which allowed ultra-fast-fashion operators to benefit from tax allowances when donating unsold goods to charitable associations. The re-introduction of a blanket ban on advertising for ultra-express fashion operators was also appreciated. 'This law does not prohibit, it protects by defining what is abnormal. It protects our environment and that of our children. It protects the economy and our textile industry. We can be happy we are giving ourselves the means to achieve our goals,' said Nicole Bonnefoy, representing the Socialist, Ecologist and Republican group, adding that 'we welcome the re-introduction of article three, which will form a negotiation basis for requesting an amendment to the European e-commerce directive, so that these restrictive measures can be made to apply to companies based for example in Ireland.' Although the amendments have been approved by the groups, several points still prompted strong reservations. The introduction of the term 'ultra-express fashion' has led to much teeth-gnashing among environmental associations and sustainable fashion brands, which believe that the aim of fencing in all types of fast-fashion practices is no longer being pursued. Jacques Fernique of Ecologist group Solidarité et territoires insisted on this aspect, emphasising that the various laws will not enter into force for many months yet, since they have to be examined again by the European Commission and the joint parliamentary committee, something which won't happen before the autumn. 'Today's vote is a relatively positive step. Shein, Temu and Amazon are pushing to the extreme a business model that destroys local jobs and our city centres' appeal. But both ultra-express fast fashion and fast fashion adopt the same approach, selling transient, low-cost disposable products. This bill is targeting the ultra-fast fashion explosion, but we can't see why the penalties shouldn't potentially apply to everyone.' Fernique is campaigning for provisions that would 'push back against the kind of disposable fashion sold by foreign platforms but also by French and European companies. It's sustainable fashion that we ought to promote, regardless of the nationality of who sells it.' An issue which the majority of senators did not endorse. 'This bill has set a course. It doesn't pretend to solve everything, but it intends to draw boundaries,' said Valente Le Hir, who is affiliated with the Republican group and is the bill's rapporteur in the Senate. She has advocated for the middle ground in various issues, asserting that the Senate wants to draw up a 'stronger bill, not a travesty of it. We have said it's time to limit the excesses of express fashion without penalising those who are working towards greater sustainability in the industry. [The bill] has distinguished, within a poorly understood sector, what constitutes planned overconsumption and what constitutes sustainable innovation. We've clarified the target. We've drawn a clear line between what we want to regulate, ultra-express fast fashion as embodied by platforms like Shein and Temu, and what we want to preserve, in other words affordable, locally rooted fashion that generates jobs in France, that anchors our communities, creates connections and boosts local industry.' After the government will have sent the text over to the European Commission, the latter will have three to four months to comment. And while French MPs and senators will be working within the joint parliamentary committee, the Commission's analysis and observations will play a key role in the bill's final wording and provisions. In the meantime, the lobbying efforts that have been ongoing for months are set to continue.
