Dutch invent world’s first cement separating machine

Amsterdam company Rutte Groep has succeeded in building a machine capable of recycling cement – a world first. The machine is called ‘Freement’, which is being presented today at the Provada fair in Amsterdam together with the New Horizon Urban Mining company.

Fremeent, invented by Koos Schenk, can separate blocks of cement into its three original materials of gravel, sand and cement. It is a big deal, considering that producing cement is responsible for nine percent of the world’s carbon dioxide emissions. Not unlike a cow, the machine ‘ruminates’ cement until the gravel is clean. Freement can process 130.000 tonnes of cement a year.

Dutch app helps you sort your recycling

Filed under: Sustainability,Technology by Orangemaster @ 6:34 pm

On 23 May, Dutch company Sitio IT launched the free phone app EcoScan for Android and iOS that helps you figure out in what recycling bin you need to sort things you’re throwing out.

In the Netherlands, there are bins for paper, plastic, glass and a few more that makes life complicated, and every municipality seems to have different bins as well. And you don’t want to be that person who puts an old lamp bulb in with the glass and forces someone somewhere to ‘disinfect’ your mistake. Sitio IT claim that there are 10 to 15 different bins for things, and this prompted developer Rick Buiten to comp up with an app for doing the right thing easier.

By using a photo scan, EcoScan can even tell you that you’d better bring certain things to the thrift shop, as they are not meant for any bins. Although I very much like the idea, I’m going to assume it’s still being beta tested or I’m really bad at scanning, as I’ve just tried it plastic, paper and glass, and it didn’t recognised any of them. And it’s only available in Dutch, but it’s point and click.

PostNL tells man to move to avoid van fumes

Filed under: General,Health,Sustainability by Orangemaster @ 12:57 pm

Mailboxes-495x286

An Amsterdam resident asked on Twitter why PostNL’s delivery personnel leave their van on his street with the motor running, which is bad for the environment. PostNL’s Twitter team decided to mention their environmentally friendly plans to replace the diesel vans with zero-emission ones, but that it takes time. To drive their point home, PostNL told the man to shop for a new house in the country if he was worried about his one-year-boy inhaling diesel fumes. That’s corporate Dutch speak for “fuck you”.

A classic comment you’ll hear often in Amsterdam is ‘if you don’t like the noise or nuisance or whatever big city problem you’re whinging about, move to the country’. Many people, some with children some without, enjoy the big city vibe Amsterdam offers, but deep down inside would like their street or neighbourhood to be some sort of mini-village where the big city problems only affect the people living in the city centre, where most of the merriment and the tourists are. However unrealistic that is, the van has no good reason to leave its motor running and PostNL was not very customer friendly with their answer.

Cider from discarded apples in Groningen

Filed under: Food & Drink,Sustainability by Orangemaster @ 2:11 pm

Screen Shot 2018-05-09 at 16.03.17

A group of four middle school friends who call themselves the Doggerland team is launching their first cider made from leftover apples from gardens and orchards in the Groningen area. At the end of last year, people could donate their leftover apples for the cider and it’s now time to taste the results. In April, two ciders were launched: Gembergloed (with ginger) and Honinghout (with honey).

Doggerland explains that people with apple trees sometimes experience the harvest as a problem: they make apple pie and some compote, and then they are stuck with hundreds of kilos of apples that fall on the grass, get jammed in the lawn mower or attract wasps. “We wanted to do something about the unwanted apples and decided to make cider”, explains Marleen, one of the founders of Doggerland.

If you live in the Groningen area and donate a minimum of 10 kilos of apples to them, Doggerland will hook you up with some cider in return. There’s even a Facebook group for this very transaction. The cider is being made in the Biotoop, a former biomedical centre of the University of Groningen in the town of Haren, aptly being brewed in the old chemisty laboratory.

Flying a hydrofoil boat is like riding a bike

Filed under: Bicycles,Sustainability,Technology by Branko Collin @ 12:10 am

Controlling a single-track hydrofoil is like controlling a bicycle, two Masters student from Delft University claim in a paper published in Naval Engineers Journal last month.

“We used a mathematical model to validate whether a single-track hydrofoil using two foils, one behind the other in the water, would remain stable in the same way as we stay upright on a bike,” one of the students, Gijsbert van Marrewijk, told Delft University last week. The principle of staying upright on a bike is the one of steering into the fall.

Van Marrewijk and his co-author Johan Schonebaum were inspired by the hydrofoil boat of the Solar Boat team of their university, of which they were members. Hydrofoil boats have wings under the hull that lift the boat out of the water, reducing drag and, all other things being equal, increasing speed. Using a single-track hydrofoil reduces drag even further over the more conventional and more stable multi-track vehicle.

See the 2015 version of the Delft University Solar Boat team in action:

For some reason recent versions of the boat have returned to multi-track hydrofoils. The mathematical model developed by the two students should make it easier to test new designs in a computer simulation.

Dutch university reveals world’s first circular car

Filed under: Automobiles,Dutch first,Sustainability by Orangemaster @ 3:22 pm

noah-ev

Last month, students from the Eindhoven University of Technology revealed ‘Noah’, the world’s first circular car. Noah is made of entirely recyclable material that is easy to disassemble. The two-seater weighs 350 kilogrammes and is powered by six modular batteries. In July the students will demonstrate that Noah is also a practical road legal car.

The plan is also to prove that circularity (true sustainability) is already possible for complicated products like cars. The design team will use renewable resources to further develop bio based materials, drive fully electric and design Noah to be recycled, making Noah the most sustainable car in the world.

Noah’s motors have a power of 15kW, to reach a speed of about 100 km/h and a total range of 240 kilometres. At the end of the lifecycle, the car will be fully recyclable, lowering the need for raw materials and giving the used materials a new life.

Amsterdam boasts world’s first plastic-free supermarket

Filed under: Dutch first,Food & Drink,Sustainability by Orangemaster @ 9:08 pm

A few days ago, a branch of organic food supermarket chain Ekoplaza in Amsterdam West not far from 24oranges HQ, opened a plastic-free pop-up supermarket, selling close to 700 plastic-free products. Although the initiative comes from international action group A Plastic Planet from London, Amsterdam’s Plastic Soup Foundation was able to convince the Londoners to launch the world premiere in the Dutch capital.

The packaging resembles the look, feel and strength of real plastic, but is made using natural, 100% biodegradable materials. Ekoplaza has 74 supermarkets throughout the Netherlands and hopes to rollout this concept to other branches by the end of 2018.

“Dutch designers Eric Klarenbeek and Maartje Dros developed a bioplastic made from algae, which they believe could completely replace synthetic plastics over time, while Design Academy Eindhoven graduate Shahar Livne created a clay-like material using discarded plastic.”

And if they can do, so can everybody else at some point, starting with the insane amount of uselessly, individually wrapped vegetables at regular supermarkets.

Groningen Rhapsody, protest song about earthquakes by Maartje & Kine

Filed under: Music,Nature,Sustainability by Branko Collin @ 4:37 pm

The ninth largest gas field in the world is located under the Dutch province of Groningen and extensive exploitation has led to an instability of the ground. In 2015 local comedy duo Maartje & Kine wrote this parody of a famous rhapsody in which they lament the troubles the region has seen.

groningen-rhapsody-maartje-kineThe lyrics are in Dutch, but you could try your luck with YouTube’s automated translation. Here are some quotes to get you going.

“Open your eyes, look at your barn and see… [a crack].”
“Our cows only produce milkshake these days.”
“He is the minister, evil and sinister.”

Last month, Groningen was hit by a gas exploitation induced earthquake that registered 3.4 on the Richter scale. It was the strongest quake in Groningen since 2012 and the fifth quake that month. As a result, 3,000 citizens filed insurance claims, on top of the 100,000 claims made earlier.

‘Dutch produce tons of food, but it’s bland’

Filed under: Food & Drink,Sustainability by Orangemaster @ 9:42 pm

Saying that this small country can feed the world sounds very impressive, but when the crops are only for profit, you wonder what you’re buying. Subjectively, most people who live in the Netherlands and who are either not of Dutch origin or have lived abroad wonder very often on social media and at parties why Dutch-grown tomatoes and cucumbers taste like water. Google ‘Wasserbombe’ and find out what Germans think of these red-coloured ‘water bombs’.

“A country [like the Netherlands] can become an agricultural powerhouse without having a rich food culture, but the focus on price, efficiency, and practicality has undermined how the Dutch both consume and produce their food”, says Pinar Coskun of Erasmus University of Rotterdam, also echoed by Leo Marcelis, Professor of horticulture at Wageningen University, according to Yes Magazine.

In September 2016, National Geographic sung the praises of Dutch agriculture, with no discussion at all on taste, purely on output, saying that “more than half the nation’s land area is used for agriculture and horticulture.” Sure, if it’s just about feeding people like in a sci-fi series, sure. But if you want some sort of quality, that’s the not the point. To be fair, that’s possibly the case in many countries around the world.

There was also the onion-shallot war between the Netherlands and France. The Netherlands produce cheap shallots by replanting shallot bulbs and harvesting mechanically, while the French plant seeds and harvest manually. The Dutch shallots are cheaper, that’s for sure.

Netherlands gets first energy-neutral house

Filed under: Architecture,Sustainability by Orangemaster @ 10:39 am

inovahuis

The small village of Abbenes, North Holland is home to the very first enery-neutral pop-up house in the country, based on a design from the company Pop-Up House that hails from Marseille, France.

Claiming to make passive construction easy, the idea is to build homes that are not only affordable, but also free of energy costs, in this case, natural gas. I specify ‘natural gas’ because electricity is not considered an energy cost for most people around the world, but I come from Québec, Canada where about 90 of heating is generated from electricity, with natural gas as a back-up during winters like the one they’re having right now.

“A passive house is a building which has limited heat loss and takes advantage of natural factors in its direct environment (bio-climatic design). A passive house’s energy consumption is very low and thermal indoor comfort is ensured all year long.” To me, this sounds great in a part of the world that barely sees a minus on the thermometer.

This Lego-like house (see video) also costs 80 per cent less than a ‘normal’ house and can be built much faster, in about five months, according to Pop-Up House.
