Dutch banknotes partially made from fair trade cotton

Filed under: General,Sustainability by Branko Collin @ 11:55 am

In 2007 the Dutch mint started with a pilot project that made it the first in Europe to print money using cotton for which the producers have not been exploited. So far, the 20 and 50 euro bills produced by De Nederlandsche Bank have contained 10 to 14% fair trade cotton.

Paper factories prefer blends of cotton, and according to the mint (PDF, Dutch) “currently there is not enough good fair trade cotton to make up 100% of a bill. But the fair trade cotton market is growing spectacularly.”

The use of fair trade cotton in Euro notes is the result of a bet that the youth chapter of Christian union CNV made in 2005 with the Minister of Finance at that time, Gerrit Zalm.

Turning leftover airplane food into electricity

Filed under: Aviation,Food & Drink,Science,Sustainability by Orangemaster @ 10:44 am

Dutch airline KLM is planning to use the leftovers of 50,000 airplane meals to produce electricity. The idea is to convert waste (refuse and food) into oil and then burn in a gas turbine at a new power station on Schiphol Airport grounds. A feasability study is currently being done and a decision will be made at the end of September.

With an investment of less than EUR 10 mln, the power station could process 20 tonnes of waste a day, which is enough to handle the leftover food. The turbine would then be able of providing electricity for 4,000 homes.

Inner city cargo train system in Utrecht

Filed under: Automobiles,Sustainability by Branko Collin @ 1:28 pm

When I was a teenager, I had to bike through the narrow and windy cobblestone streets of a typically Dutch city centre to get to school, and part of that ride was spent waiting behind large, four-ton trucks delivering who knows what. Maybe it was 50 envelopes or a crate of tomatoes. It gave me the time to muse about a system where cargo was off-loaded just outside the city centre to smaller, horse-drawn carts for further distribution.

Although Utrecht-based company Cargohopper ditched the horse, they did implement this scheme for distributing goods to inner city stores to a tee. The small width, 1.25 metre, will surely lead to less irritation for the other road users.

Some figures from the company:

Cargohopper is a vehicle that can tow 3 metric tonnes in a linear line by means of a 48 Volt 28 hp electric engine. Its max speed is 20 km/h, but that is more than enough as it is only driving in the inner city of Utrecht and does not do more than 60 kilometres a day.

[…]

Once empty, it collects dry cardboard, paper and empty packaging from shops for recycling, so it never runs empty. In this way, Cargohopper removes up to 100,000 van kilometres from the inner city streets and saves about 30 tonnes of CO2 annually.

Folding cargo containers save space and energy

Filed under: Design,Dutch first,Sustainability by Orangemaster @ 11:59 am
cargoshell1

Rotterdam businessman Rene Giesbers dreamed up, helped design and launched an innovative container concept called Cargoshell, a fully foldable container made from composite that significantly reduces the amount of space empty containers take up on ships and trains. In fact, acccording to the report on Dutch television (RTL 4) yesterday, some 20% of all containers on ships and some 30% of all containers on trucks are just ’empties’ requiring much fuel to transport. According to a Dutch article earlier this year, some 20 billion euro is lost every year just transporting empty containers.

When the Cargoshell is folded, it takes up 25% of its actual size. It can be folded by one person and a forklift in just 30 seconds.

The Dutch often use foldable and obviously re-usable shopping crates, which I had never seen in North America, that look like this:

This crate was what inspired Giesbers to do the same for containers.

Sometimes innovation is really just staring at us in the face.

The Dutch-South African connection: sustainability and slippers

Filed under: Fashion,General,Sustainability by Orangemaster @ 5:30 pm
FW de Klerk

Last Friday, 12 June, under the banner of ‘Sustainability and Africa’, the Delft University of Technology welcomed former President of South Africa and Nobel Peace Prize winner, F.W. de Klerk (in the middle), who was instrumental in brokering the end of Apartheid. He told the small audience, “even though I have been in government very long, don’t trust the government too much”.

De Klerk was invited to the Netherlands by the Amsterdam-based KidsRights foundation, a joint founder of the ‘Plakkies’ slipper initiative, a successful venture started by two Delft University of Technology students. Like some Dutch people in this video, I didn’t think much of these slippers, but with some background information, not just some uppity Afrikaans advert, it made more sense.

Designed by Michel Boerrigter, plakkies (Afrikaans for ‘slippers’), are made of used car tyres and were made hip and trendy for the ‘Western market’, with South African children drawing the designs that go on them. The profit goes towards a good cause and the business employs 70 people. The only disadvantage is that they do smell of used car tyres when you first buy them, but Boerrigter reassures people that this extra charm disappears quickly enough.

Ecological font

Filed under: Design,Sustainability by Branko Collin @ 2:55 pm

Utrecht based ad agency Spranq made a font environmentally friendly by making holes in the glyphs. The result is called Ecofont, and according to an article by NPR, this will save its users up to 15% in ink. The idea is that you set this font, a free download, as the standard font for printing drafts and e-mails and such. Ecofont is based on the liberally licensed Bitstream Vera font.

Revolving door generates power

Filed under: Sustainability,Weird by Branko Collin @ 10:11 am

As if it isn’t bad enough that since they privatized, the national railroad monopolist barely seems to manage to run a train on time, to boot the NS (Dutch Railways) has now resorted to forced labour. Everybody passing through this revolving door helps the Driebergen-Zeist railway station generate a little bit of electricity. According to an enthousiastic manufacturer, Boon Edam, this is the world’s first energy generating revolving door and a breakthrough in “entrance technology.” There’s a word I bet you did not know existed. They estimate the amount of revolutions to be a scientific “gazillion times.”

The electricity thus won is used to illuminate a sign that says how much electricity the door has generated so far.

Cancel the phone book, save trees galore

Filed under: General,Sustainability by Orangemaster @ 11:09 am
Phone book

There is a petition going around that basically pleads for having the right to say no to the paper version of the phone book and the yellow pages (Gouden Gids). It’s not about taking it away from the elderly that do not bother with computers or people who actually use a paper copy, it’s about not so many of these guides ending up in the bin. Thousands and thousands do and these folks think it’s time to put a stop to it. This picture is actually of my own version waiting to be recycled yet again this year.

You can sign and read about the petition in Dutch here: Stop De Papieren Telefoongids (Stop the paper version of the (Dutch) phone book)

Air-purifying concrete for town of Hengelo

Filed under: Dutch first,Science,Sustainability by Orangemaster @ 9:34 am
Air purifier for concrete

Hengelo, Overijssel looks to be taking a rather unique approach to cleaning the air, with it now testing out a new type of “air-purifying concrete” developed by the University of Twente that promises to soak up the nitrogen oxide particles emitted by car exhausts. This is done with the aid of a titanium dioxide-based additive which, with the help of some sunlight, binds with the nitrogen oxide particles and turns them into harmless nitrates, which can apparently just wash away with the next rain shower. Hengelo is not fully sold on the idea just yet, with it only paving half of a road now under construction with these “green bricks”, while the other half is getting paved with plain old concrete. They will then take some air measurements from each section early next year and decide whether to continue paving the town green or not.
