These two Dutch students create 3D-printed snacks from food waste

Solutions

According to the FAO, every year, roughly one-third of all the food produced for human consumption gets lost or wasted. That’s about 1.3 billion tonnes. Unsurprisingly, fruits and vegetables have the highest wastage rates of any food.

But what if we could find ways to magically turn food waste back into perfectly edible food? This is what Elzelinde Van Doleweerd and Vita Broeken, two Dutch girls in their twenties, are trying to do with their brand new company Upprinting Food.

They’re not using magic though, they’re using  3D printing.

It all started during Elzelinde’s final bachelor’s year at the University of Eindhoven when she had the idea of utilizing 3D printing technology to upcycle food waste into edible products. She decided to focus on bread because it’s the number one wasted food product in the Netherlands.

To create a printable food paste, Elzelinde mashed the old bread and added spices and herbs to make it more flavorful. Afterward, she filled a syringe with the paste and injected it in the printer. Finally, she baked and dehydrated the printed food, to make it last longer. The final product was a crunchy, yummy snack.

Aside from the fact that to me this still sounds like magic, it also sounds like an intriguing way to rethink food waste. Many people agreed and the project was presented at the Dutch Design Week 2018last October, where it was warmly received.

Encouraged by such a positive feedback, Elzelinde decided to bring her upcycling idea to the next level and partnered up with Vita Broeken to found the company Upprinting Food. Together, they worked hard to expand the number of wasted ingredients they can work with (which now includes fruits and vegetables) and to create additional recipes for new food pastes. At the moment, their aim is to help restaurants to analyze and reuse their food waste.

As is often the case with these nifty innovations, scaling them is the main obstacle and Elzelinde and Vita’s product is no exception. However, despite their young age, the two entrepreneurs are not shying away from this challenge and are studying possible ways to overcome the issue.

In all this, a few days ago, they were awarded the ECO Coin Award 2018 - a prize promoted by Dutch organization Next Nature Networkto honor “outstanding ecological heroes” - for their “strong and innovative concept that could truly change the world for the better.” Not bad at all for an idea that started off as a simple university project.

  • Muslim doctors open free clinic for uninsured patients in a Ohio mosque

    Solutions

    In this time of religious tensions, a small piece of good news can go a long way in restoring your faith in humanity. This positive bit, for example, comes all the way from the United States. Northeast Ohio, to be precise.

    👉 In Parma, a small city close to Cleveland, a group of Muslim doctors decided to convert some of the local mosque's spare rooms into a free health clinic where everybody is welcomed, no matter if uninsured or not Muslim.

    As reported by local media outlet News5 Cleveland, The Cleveland Ibn Sina Clinic opened just a few weekends ago but more than 30 patients have already received treatment.

    "We have the ability, we have the potential, we have the resources,” said Dr. Mansoor Ahmed, who is one of the 20 doctors that committed to volunteering their expertise. "Giving a little bit of your time, I think, goes a long way in making a difference in people's lives," he added.

    “A lot of the doctors came here from foreign countries outside the United States looking for better opportunities. Now that they are established, some of them are practicing with hospitals, some of them have their own practice, now they want to come together and give back to the community,” commented Hala Sanyurah, who is the clinic's Communication Director.

    The clinic — that will not just focus on primary health issues but also on more specific diseases like asthma, diabetes, and mental illness  is the first free medical facility in the region.

  • Winter was frigid because the polar vortex got ‘drunk'

    Obstacles

    The mere mention of the term “polar vortex” elicits thoughts of bitterly cold temperatures and dangerous wind chills. Most people are aware that the frigid air in the Northern Hemisphere is coming directly from the Arctic region, yet they don’t know why polar vortexes happen.

    Not surprisingly, this has led to some rather heated debate. One side of the argument claims that the polar vortex is a result of climate change and human activity. The other side suggests this is a natural phenomenon that proves global warming is false and that humans are not involved in altering our climate.

    The truth is the former is correct. But trying to convince someone to accept this reality might be a difficult challenge. Thankfully, when it comes to the cause of the polar vortex, there is a relatively easy — and for some, relatable — explanation. Quite simply, the polar vortex gets drunk.

    My research expertise is in microbiology, immunology and chemical mechanisms of molecular interaction (think antibiotics).

    As a science communicator, one of my greatest hurdles is defining the intricacies of research into language with which people can understand. This means going deep into the literature and finding the mechanism behind the result. It also means having a deep level of knowledge in a variety of different science branches.

    In some cases, the information can be difficult to convey to a wider audience. But when it comes to the polar vortex, it’s not difficult at all.

    A close examination of the chemistry associated with the onset of these cold snaps reveals a near-perfect resemblance to a chemical shift our bodies encounter during alcohol consumption. The results reveal that both humans and the planet are similarly susceptible to unexpected and unwanted movements.

    Unstable masses

    Most of us can recognize when someone has had too much to drink. Their speech is slurred and they have troubles with their balance. This latter symptom is why the walk-and-turn sobriety test is effective — an inebriated person has trouble moving in a straight line.

    Maintaining posture and balance is a complicated neurological process. Research has revealed that one molecule, gamma aminobutyric acid (GABA), is necessary for us to achieve this goal. Our brains use this neurotransmitter to help control the signals to our muscles, particularly when we feel the effects of gravity or being pushed by another person.

    When we drink alcohol, GABA helps us preserve our balance and posture. But once we end up losing the necessary levels of GABA needed to keep us upright, we sway, stagger and stumble. Only when we’ve sobered up and increased our GABA levels are we able to regain our balance.

    A similar process occurs in the Arctic.

    Cold sober

    The polar vortex, officially known as the stratospheric polar vortex (SPV), is a stable air mass that tends to stay put when it’s cold sober. In the same way we feel an internal heat during alcohol consumption, the region can warm up with an infiltration of air from the south, better known as a sudden stratospheric warming. When this happens, the steadiness of the vortex is challenged.

    Much like our brains have GABA to maintain stability, the SPV also has a chemical that helps to maintain stability. It’s ozone.

    When levels remain high, the vortex stays in place. But should the levels drop, then the vortex starts to sway, stagger and then stumble southward, a process known as outward eddy transport. Depending on how low the ozone levels drop, the vortex can stretch well into the southern United States and Europe. Eventually, the SPV sobers up, the ozone levels recover, and the air mass stays up north. But this recovery can be slow and leave those affected freezing for weeks instead of days.

    As to what causes the ozone loss, it’s a reaction with a variety of chemicals in the air. Researchers can observe the process in real time and have found that the offenders are not alcoholic in nature but happen to be compounds that contain nitrogen and chlorine. The Earth produces these chemicals in the form of volcanic output and forest fire emissions, and this can lead to a drunk polar region.

    But the frequency of these events has increased from one every few years to one very few months. There must be another perpetrator.

    Thanks to real-time examinations of polar vortex movements over the last 20 years, we can easily finger the culprit: industrial air pollution. These commercial activities produce more than enough of the nitrogen and chlorine chemicals to reduce ozone levels and cause those drunken staggers. The data clearly shows that the blame for the rise in those cold blasts falls squarely on us.

    As this winter’s supply of polar vortex events comes to an end, so should the debate over whether the polar vortex is real — it is — and whether these movements are due to human activity — they are. Until we find ways to reduce our dependence on ozone-removing chemicals, all we can do is hope for the best and brace for the worst.

  • Inside the Hospital of St. Cross, UK's oldest charitable institution

    Solutions

    Here at Kinder, we're often busy thinking about the future of philanthropy and how charitable organizations will look like 100 years from now.

    However, every now and then, it's also helpful to look back at history and realize that there's a handful of charities that have been around for so long that there's certainly something we can learn from them.

    One of them is the Hospital of St. Cross and Almshouse of Noble Poverty in Winchester England, that actually prides itself to be the UK's oldest charitable institution.

    Founded around the year 1132, the almshouse was initiated by Bishop Henry of Blois to support thirteen poor men who were unable to work and to feed some 100 people who showed up at the gates every day.

    The thirteen men became known as the "Brothers of St. Cross". Despite the religious connotations of the term "brother", the Brothers of St. Cross were not and are not monks, therefore St. Cross is not a monastery. 

    The Wayfarer's Dole

    The Hospital of St. Cross' most unique and famous charitable endeavor is surely the so-called "Wayfarer's dole".

    According to this delightful tradition, every visitor of the almshouse can ask for a free horn of beer and a morsel of bread. As recalled by the organization's website, the custom was started by a monk from Cluny, in France, whose holy order always gave bread and wine to travelers.

    After so many centuries, this tradition still continues nowadays as seen in the BBC's program Songs of Praise👇

    The Hospital of St. Cross, which is hosted in a beautiful medieval building immersed in the British countryside, is regularly open for visits. Head to the organization's website for additional information.
