Leaving the grave out

When discussing sustainability the term “lifecycle analysis” sometimes comes up. The idea is that it’s important to figure out a product’s full impact, from production to destruction, from cradle to grave.

But what if there were no need to bury things? This is the thought behind the Cradle to Cradle concept, developed by the American chemistry professor Michael Braungart together with the architect William McDonough in the book ”Remaking the way we make things” published in 2002.

The idea of the Cradle to Cradle concept is to use Nature’s own processes as a model for human production, bringing all materials back either to the technological or to the biological cycle.

These ideas have gained ground in Sweden, and for example several fashion designers are now trying to incorporate this thinking in their work. One of them is Mathilda Wendelboe, who is presenting her own Cradle to Cradle collection this week.

She says that she won’t just be working with biodegradable organic materials but also “technological non-organic materials”, which through the right design will be possible to reuse almost infinitely.

– The goal is to imitate Nature’s own cycles also in the industry, and make sure the materials are brought back when these garments are not used any more, she says.

Other designers who have recently started using their first Cradle to Cradle certified fabrics in children’s clothes are Bonkeli.

Here is a video explaining a bit more about the idea of Cradle to Cradle:

Spring breakfast for hungry insects

Every morning cycling to work I am eagerly looking for new signs of the green explosion that I know is soon to come. So far, the trees are still naked and grey, hiding their leaves. There is one exception, though: The sallow. Its flowers look as yellowish clouds from far away, and its nectar and pollen are the first meal that many insects get when they wake up after a cold winter.

A few days ago I joined an excursion to learn a bit more about this. The Swedish Biodiversity Centre has, together with WWF and the Swedish Society for Nature Conservation, published a book solely dedicated to the sallow. Its author, the insect expert Bengt Ehnström, showed us around, opening our eyes to a tree that is depreciated and many times cleared away in parks and forests.

What is often forgotten then is that the sallow plays an important role, not only for the insects eating its nectar and pollen or living in its bark. Almost 180 different kinds of caterpillars eat the leaves and start their metamorphosis to become butterflies among the sallow branches. Looking a step further in the chain, these insects mean good food for tired migratory birds arriving after long flights from the south. The bees and bumble-bees are also an extremely important workforce for farmers and gardeners, pollinating fruit trees, bushes that will bear berries and whole rapeseed fields. Without them there wouldn’t be any blueberries.

All this reminds me a lot about the intricate system that an ecosystem is, with every little part of it depending on a whole range of others. 2010 is the UN International Year of Biodiversity . In this video the UN Secretary-General Ban-Ki Moon explains why.


Volcanic solidarity

As in so many other countries, Sweden has been lagerly affected by the Islandic volcanic eruption. During the last week tourists have been unable to return home, meetings have been cancelled and missing deliveries have put some industries in tricky situations.
Of course this means a lot of trouble for a lot of people, but I think the volcano has opened our eyes to some things we haven’t thought about in a long time, and brought up some interesting discussions.

Reduced emissions
Some argue that the volcano has actually managed, in just a few days, to do what politicians and others in power have said must be done but failed in doing: to reduce our emissions of greenhouse gases by changing human behaviour.
According to estimates made by scientists, the cancelled flights spare the atmosphere hundreds of thousand tons of CO2 emissions every day, even considering the emissions from Eyjafjallajökull itself.

Less noise
This, of course, is just a temporary reduction and won’t make any significant difference for the climate in the long run. But it is nevertheless a full scale experiment of what the effects of reducing flight transports could be.
Reports from the neighbourhoods surrounding some of our largest airports also show that people living there experience an enormous difference in their everyday life. Without planes landing and taking off all day, they can suddenly sit in their gardens without being bothered by noise.

Acting fast
This past week also shows how much easier it is to go to action when something happens as fast and as concrete as the volcanic eruption, in contrast to climate change and peak oil which are much slower processes, easier to ignore for the moment.
Now people have had to adapt in just a few days, and have come up with amazing solutions.

Volcanohelp

Last weekend the two Swedish students Måns Gårdfeldt och Jonas Larsson started the web service Volcanohelp which helps people who are stranded somewhere because of the volcano to find a ride and a place to stay.  It’s fascinating to see how people find each other, offering seats in a bus from Croatia to Stockholm or a car going from Paris to London. Some of course see their chance of making good money, but there are also lots of people just trying to help each other. A nice act of solidarity, and maybe this can awake new ideas about how to travel, even when the volcano has calmed down?

Bikes for all

This Greenstreet bike was found at Järntorget in central Gothenburg, an early evening ideal for rolling around the city. The lock being put through the green hole indicates that the bike is free to use.

The ice on the streets is long gone in most parts of Sweden, and suddenly the cyclist has become a common urban specie.
Personally I feel a bit lonely and limited without my bike. So when I am travelling I’m always very happy to come to places where I can borrow a bike. Seeing Paris, London, Barcelona or the Indian village of Chengalpattu from a bike has given me perspectives of those places that I wouldn’t have got from a bus window.

City bikes

This is why I am enormously fond of bike sharing systems, which are being introduced in more and more cities. Here in Stockholm there are 1000 city bikes for rent on the streets.
In Gothenburg the same system will be introduced this summer, but since a few years back it is already possible to borrow a bike thorugh a creative initiative.

Text a bike

Greenstreet is an association which has developed its own bike-sharing system in Gothenburg. One interesting thing about it is that there are no fixed stations for their bikes. They can simply be left and picked up anywhere in the city. On their website registred users can find the position of the bikes, and when you spot the green cycle of your choice, you send a text message and receive a code that will allow you to unlock the bike.
When it’s time to leave it, all you have to do is to send another text message, containing the address where the bike is being parked.

Winning concept

Recently the Swedish design agency LOTS won the first prize in a bike-share competition arranged by the Danish city of Copenhagen. LOTS’s OPENbike concept actually has a lot in common with Greenstreet, allowing people to leave the bikes wherever they choose to end the trip.

Thinking outside the bottle

Bottled water is in many ways a symbolic question, that reaches beyond the emissions of plastic bottle production, the transports of the water and the waste.
This story about a visitor’s encounter with a Swedish tap makes it obvious that tasty tap water is nothing everyone counts on. But for a lot of people there is no evident need to buy bottled water. If the quality of the water coming from our taps is good, tap water is usually cleaner than stored water, and far cheaper.

Municipalities turn on the tap

Earlier I have written about how the EU delegates who attended meetings in Sweden during the European presidency were served tap water instead of bottled water. With the upcoming of the climate change debate, many municipalities allover the country, such as Uppsala, Östersund and Jönköping also decided to stop buying bottled water.
For some time the interest for buying bottled water has semmed to fade, but last year the sales of bottled water was again reported to rise. Maybe this short film, which is now being shared a lot here in Sweden, will bring the discussion up once again?
