Technician Christopher Olk concentrates hard as he removes the broken drive from a DVD player and pushes it back in again.
"If it's the mechanics or the electronics, I can fix it," explains the 26-year-old, who is working on his Ph.D. in battery technology at Aachen University. "If the chip or the cooling system is affected then I can't do anything, because I'm missing the equipment and spare parts."
In a small room inside a repair cafe in Cologne's civic center, Olk is one of four technicians who, with the help of some spanners and a soldering iron, try to breathe new life into faulty electronic devices, whether it's a razor, a toaster, a screen or a lamp.
Europe is full of broken-down equipment. With more than 12 million tons per year — the equivalent of 30,000 jumbo jets — Europe ranks second only behind Asia in terms of e-waste, according to the Platform for Accelerating the Circular Economy (PACE).
Manufacturers to Make Changes
"We want to avoid electronic waste and try to motivate people to act in an environmentally conscious way," says Dunja Karabaic, one of the repair cafe's founders.
The European Commission now wants to implement a new ecodesign directive at the EU level to help ensure home appliances have a longer functional lifespan — and it's banking on regulation.
At the repair cafe in Cologne, Christopher Olk is trying to get this faulty DVD player up and running again.
As of 2021, manufacturers across Europe will be required to improve both the reparability and service life of devices such as washing machines, refrigerators, dishwashers, electric motors, light sources and LED screens. Manufacturers must also be more precise when it comes to including energy consumption information on the labels of their products and providing replacement parts for at least 10 years after purchase.
Laptops and smartphones, however, are not covered under the new rules — more on that later.
Ecological Potential and the Right to Repair
The European Commission estimates that up to 167 terawatt hours of energy could be saved annually by 2030 — approximately the same annual energy consumption as Denmark, which has a population of 5.8 million. This could be achieved, on the one hand, through more energy efficient devices, and, on the other, as a result of fewer devices needing to be re-produced if they last longer in the first place.
When it comes to electricity and acquisition prices, the European Commission projects that EU citizens would save around €150 ($167) per year in the future.
Old televisions are much easier to repair compared to modern LED screens.
"Whether it is by fostering reparability or improving water consumption, intelligent ecodesign makes us use our resources more efficiently, bringing clear economic and environmental benefits," the European Commission Vice President for Jobs, Growth, Investment and Competitiveness, Jyrki Katainen, said in an official statement.
Environmental organizations have also welcomed the new regulations.
"From the U.S. to Europe, people are demanding their right to repair things they own because they're tired of products that are designed to break prematurely," said Chloe Fayole, the program and strategy director at the environmental organization ECOS. "Enabling consumers to repair and reuse all electronic products is just common sense."
How Long Should Devices Last?
Exactly how much longer electronic devices should last in the future is still unclear, as is a more detailed benefit analysis of the plan. But if the devices are easier to repair, "the turnover of product inventories will automatically decrease," Pierre Schweitzer, an expert on ecodesign at the European Environment Bureau (EEB) told DW. "That means that less electronic waste will be produced. But no one has tested the model yet, as to whether this will happen in practice."
The EEB has therefore submitted a report looking at the effects of measures which prolong the life of electronic devices. The calculations show that if washing machines in Europe were to function for just one extra year, it would have the same positive effect on the environment as if 133,000 cars were taken off the road.
On average, a washing machine currently lasts around 11 years. But according to the experts, it would have to be used for at least 20 years before the purchase of a new washing machine is advisable from an environmental point of view.
"That's how long it takes resources to use an old device — and to repair it," explains Rasmus Priess, a product sustainability expert from the Öko-Institut in Freiburg.
But not all electronic devices are created equal. If the energy footprint required to manufacture and then run a device is taken into account, a laptop should be used for 44 years, and a smartphone for up to 232 years. As mentioned earlier, these devices – along with small appliances like razors, blenders and toasters – won't be included in the new EU rules. The plan is to incorporate them at a later stage.
The DVD player, which Christopher Olk is busy fixing in the repair café in Cologne, hasn't made it onto the European Commission's list yet either.
Brussels will soon be discussing whether to include longer-lasting smartphones and laptops in the new regulations.
Gaps in the Rules
It took Olk 30 minutes to remove the device's case and take a look inside. After some tinkering, he still only managed open it by force. "See that old radio over there," he said, pointing to an antique mustard yellow transistor radio that has probably been around for several decades, "Underneath is a guide on how to open it and remove some of the parts. Something like that alone would help."
The German Federal Ministry for Economic Affairs and Technology (BMWI) has also been negotiating in Brussels. In a statement provided to DW, it says it is committed to ensuring that customers can make simple repairs themselves, while more difficult or dangerous repairs should be done by a specialist.
The cost of replacement parts may also limit the overall success of the new regulations: The scheme doesn't include a price break for spare parts.
Jean-Pierre Schweitzer from the EEB believes this has increased the risk of "an economic incentive to make spare parts either very expensive, or to manufacture products that break down regularly."
The more complicated the technology, the harder it is to identify which parts are broken.
An analysis by the Joint Research Center of the European Commission found that the main reason people didn't have a washing machine or dishwasher repaired was because "it was too expensive."
Paolo Falcioni, the Director General of APPLiA, an association representing home appliance manufacturers in Europe, has nevertheless praised the regulations as "a balanced representation of interests." But he also sees some disadvantages. On the one hand, APPLiA fears that the regulations would mean fewer devices would be approved for the European market. On the other hand, it also wants to avoid any unfair competition.
'Repairing Is More Important Than Recycling'
But although there is still room for improvement, Jean Pierre Schweizer from EEB says the new legislation is "groundbreaking" because it acknowledges the importance of using devices as long as possible.
"When we talk about a circular economy, repairing is a very efficient point at which you can save real resources and emissions — and that's just the start. We really should highlight the positive aspects of this legislation."
Not all electronic devices can be repaired using normal, everyday tools.
Back at the repair cafe, Christopher Olk has given up. The DVD player is beyond saving. This isn't an unusual outcome here.
Braco Sladakovic, who brought in his defective LED TV, has also admitted defeat. The backlight no longer works.
"We tried, but it was too complicated," he told DW. "It's not worth it anymore, unfortunately." The spare part needed is cheap enough to replace, but the repair itself would be too difficult and expensive.
Sladakovic now needs to decide what to do with his broken TV. He might be able to sell if to a hobbyist for a few euros. Or he'll simply take it to the nearest electronic waste dump.

A Healthy Microbiome Builds a Strong Immune System That Could Help Defeat COVID-19
By Ana Maldonado-Contreras
Takeaways
- Your gut is home to trillions of bacteria that are vital for keeping you healthy.
- Some of these microbes help to regulate the immune system.
- New research, which has not yet been peer-reviewed, shows the presence of certain bacteria in the gut may reveal which people are more vulnerable to a more severe case of COVID-19.
You may not know it, but you have an army of microbes living inside of you that are essential for fighting off threats, including the virus that causes COVID-19.
How Do Resident Bacteria Keep You Healthy?
<p>Our immune defense is part of a complex biological response against harmful pathogens, such as viruses or bacteria. However, because our bodies are inhabited by trillions of mostly beneficial bacteria, virus and fungi, activation of our immune response is tightly regulated to distinguish between harmful and helpful microbes.</p><p>Our bacteria are spectacular companions diligently helping prime our immune system defenses to combat infections. A seminal study found that mice treated with antibiotics that eliminate bacteria in the gut exhibited an impaired immune response. These animals had low counts of virus-fighting white blood cells, weak antibody responses and poor production of a protein that is vital for <a href="https://doi.org/10.1073/pnas.1019378108" target="_blank">combating viral infection and modulating the immune response</a>.</p><p><a href="https://doi.org/10.1371/journal.pone.0184976" target="_blank" rel="noopener noreferrer">In another study</a>, mice were fed <em>Lactobacillus</em> bacteria, commonly used as probiotic in fermented food. These microbes reduced the severity of influenza infection. The <em>Lactobacillus</em>-treated mice did not lose weight and had only mild lung damage compared with untreated mice. Similarly, others have found that treatment of mice with <em>Lactobacillus</em> protects against different <a href="https://doi.org/10.1038/srep04638" target="_blank" rel="noopener noreferrer">subtypes of</a> <a href="https://doi.org/10.1038/s41598-017-17487-8" target="_blank" rel="noopener noreferrer">influenza</a> <a href="https://doi.org/10.1371/journal.ppat.1008072" target="_blank" rel="noopener noreferrer">virus</a> and human respiratory syncytial virus – the <a href="https://doi.org/10.1038/s41598-019-39602-7" target="_blank" rel="noopener noreferrer">major cause of viral bronchiolitis and pneumonia in children</a>.</p>Chronic Disease and Microbes
<p>Patients with chronic illnesses including Type 2 diabetes, obesity and cardiovascular disease exhibit a hyperactive immune system that fails to recognize a harmless stimulus and is linked to an altered gut microbiome.</p><p>In these chronic diseases, the gut microbiome lacks bacteria that activate <a href="https://doi.org/10.1126/science.1198469" target="_blank" rel="noopener noreferrer">immune cells</a> that block the response against harmless bacteria in our guts. Such alteration of the gut microbiome is also observed in <a href="https://doi.org/10.1073/pnas.1002601107" target="_blank" rel="noopener noreferrer">babies delivered by cesarean section</a>, individuals consuming a poor <a href="https://doi.org/10.1038/nature12820" target="_blank" rel="noopener noreferrer">diet</a> and the <a href="https://doi.org/10.1038/nature11053" target="_blank" rel="noopener noreferrer">elderly</a>.</p><p>In the U.S., 117 million individuals – about half the adult population – <a href="https://health.gov/our-work/food-nutrition/2015-2020-dietary-guidelines/guidelines/" target="_blank" rel="noopener noreferrer">suffer from Type 2 diabetes, obesity, cardiovascular disease or a combination of them</a>. That suggests that half of American adults carry a faulty microbiome army.</p><p>Research in my laboratory focuses on identifying gut bacteria that are critical for creating a balanced immune system, which fights life-threatening bacterial and viral infections, while tolerating the beneficial bacteria in and on us.</p><p>Given that diet affects the diversity of bacteria in the gut, <a href="https://www.umassmed.edu/nutrition/melody-trial-info/" target="_blank" rel="noopener noreferrer">my lab studies show how diet can be used</a> as a therapy for chronic diseases. Using different foods, people can shift their gut microbiome to one that boosts a healthy immune response.</p><p>A fraction of patients infected with SARS-CoV-2, the virus that causes COVID-19 disease, develop severe complications that require hospitalization in intensive care units. What do many of those patients have in common? <a href="https://www.cdc.gov/mmwr/volumes/69/wr/mm6912e2.htm" target="_blank" rel="noopener noreferrer">Old age</a> and chronic diet-related diseases like obesity, Type 2 diabetes and cardiovascular disease.</p><p><a href="http://doi.org/10.1016/j.jada.2008.12.019" target="_blank" rel="noopener noreferrer">Black and Latinx people are disproportionately affected by obesity, Type 2 diabetes and cardiovascular disease</a>, all of which are linked to poor nutrition. Thus, it is not a coincidence that <a href="https://www.cdc.gov/mmwr/volumes/69/wr/mm6933e1.htm" target="_blank" rel="noopener noreferrer">these groups have suffered more deaths from COVID-19</a> compared with whites.

<p>The COVID-19 pandemic has inspired me to shift my research and explore the role of the gut microbiome in the overly aggressive immune response against SARS-CoV-2 infection.</p><p>My colleagues and I have hypothesized that critically ill SARS-CoV-2 patients with conditions like obesity, Type 2 diabetes and cardiovascular disease exhibit an altered gut microbiome that aggravates <a href="https://theconversation.com/exercise-may-help-reduce-risk-of-deadly-covid-19-complication-ards-136922" target="_blank" rel="noopener noreferrer">acute respiratory distress syndrome</a>.</p><p>Acute respiratory distress syndrome, a life-threatening lung injury, in SARS-CoV-2 patients is thought to develop from a <a href="http://doi.org/10.1016/j.cytogfr.2020.05.003" target="_blank" rel="noopener noreferrer">fatal overreaction of the immune response</a> called a <a href="https://theconversation.com/blocking-the-deadly-cytokine-storm-is-a-vital-weapon-for-treating-covid-19-137690" target="_blank" rel="noopener noreferrer">cytokine storm</a> <a href="http://doi.org/10.1016/S2213-2600(20)30216-2" target="_blank" rel="noopener noreferrer">that causes an uncontrolled flood</a> <a href="http://doi.org/10.1016/S2213-2600(20)30216-2" target="_blank" rel="noopener noreferrer">of immune cells into the lungs</a>. In these patients, their own uncontrolled inflammatory immune response, rather than the virus itself, causes the <a href="http://doi.org/10.1007/s00134-020-05991-x" target="_blank" rel="noopener noreferrer">severe lung injury and multiorgan failures</a> that lead to death.</p><p>Several studies <a href="https://doi.org/10.1016/j.trsl.2020.08.004" target="_blank" rel="noopener noreferrer">described in one recent review</a> have identified an altered gut microbiome in patients with COVID-19. However, identification of specific bacteria within the microbiome that could predict COVID-19 severity is lacking.</p><p>To address this question, my colleagues and I recruited COVID-19 hospitalized patients with severe and moderate symptoms. We collected stool and saliva samples to determine whether bacteria within the gut and oral microbiome could predict COVID-19 severity. The identification of microbiome markers that can predict the clinical outcomes of COVID-19 disease is key to help prioritize patients needing urgent treatment.</p><p><a href="https://doi.org/10.1101/2021.01.05.20249061" target="_blank" rel="noopener noreferrer">We demonstrated</a>, in a paper which has not yet been peer reviewed, that the composition of the gut microbiome is the strongest predictor of COVID-19 severity compared to patient's clinical characteristics commonly used to do so. Specifically, we identified that the presence of a bacterium in the stool – called <em>Enterococcus faecalis</em>– was a robust predictor of COVID-19 severity. Not surprisingly, <em>Enterococcus faecalis</em> has been associated with <a href="https://doi.org/10.1053/j.gastro.2011.05.035" target="_blank" rel="noopener noreferrer">chronic</a> <a href="https://doi.org/10.1016/S0002-9440(10)61172-8" target="_blank" rel="noopener noreferrer">inflammation</a>.</p><p><em>Enterococcus faecalis</em> collected from feces can be grown outside of the body in clinical laboratories. Thus, an <em>E. faecalis</em> test might be a cost-effective, rapid and relatively easy way to identify patients who are likely to require more supportive care and therapeutic interventions to improve their chances of survival.</p><p>But it is not yet clear from our research what is the contribution of the altered microbiome in the immune response to SARS-CoV-2 infection. A recent study has shown that <a href="https://doi.org/10.1101/2020.12.11.416180" target="_blank" rel="noopener noreferrer">SARS-CoV-2 infection triggers an imbalance in immune cells</a> called <a href="https://doi.org/10.1111/imr.12170" target="_blank" rel="noopener noreferrer">T regulatory cells that are critical to immune balance</a>.</p><p>Bacteria from the gut microbiome are responsible for the <a href="https://doi.org/10.7554/eLife.30916.001" target="_blank" rel="noopener noreferrer">proper activation</a> <a href="https://doi.org/10.1126/science.1198469" target="_blank" rel="noopener noreferrer">of those T-regulatory</a> <a href="https://doi.org/10.1038/nri.2016.36" target="_blank" rel="noopener noreferrer">cells</a>. Thus, researchers like me need to take repeated patient stool, saliva and blood samples over a longer time frame to learn how the altered microbiome observed in COVID-19 patients can modulate COVID-19 disease severity, perhaps by altering the development of the T-regulatory cells.</p><p>As a Latina scientist investigating interactions between diet, microbiome and immunity, I must stress the importance of better policies to improve access to healthy foods, which lead to a healthier microbiome. It is also important to design culturally sensitive dietary interventions for Black and Latinx communities. While a good-quality diet might not prevent SARS-CoV-2 infection, it can treat the underlying conditions related to its severity.</p><p><em><a href="https://theconversation.com/profiles/ana-maldonado-contreras-1152969" target="_blank">Ana Maldonado-Contreras</a> is an assistant professor of Microbiology and Physiological Systems at the University of Massachusetts Medical School.</em></p><p><em>Disclosure statement: Ana Maldonado-Contreras receives funding from The Helmsley Charitable Trust and her work has been supported by the American Gastroenterological Association.
