alles Sondermüll

vlcsnap-1088816

Eine sehr gute Dokumentation von Kathrin Latsch namens “Die grüne Revolution” über Braungart/McDonough, den Stoffkreislauf für technologische und biologische Nährstoffe und mit jeder Menge guter Praxisbeispiele – die vom NDR leider auf den unmöglichsten Sendeplatz überhaupt gesetzt wurde: in der Nacht vom Montag auf Dienstag, 15.-16.12, morgens um 3:40 Uhr.

Michael Braungart wies uns letztens auf den Sendetermin hin, also schnell den Online Videorekorder programmiert und schwupps ist die Sendung auf dem eigenen Rechner. Wer eine Kopie der Dokumentation für den Privatgebrauch haben möchte – bitte bei mir melden. Sind 460 MB, DiVX-Qualität.

Was Ihr auf dem Screenshot seht, stellt den Windelbedarf eines Kindes während des ersten Lebensjahres dar. 1800 Stück. Wären die Windeln alle biologisch abbaubar, würden sie später nicht als Sondermüll enden. Braungart sagt in der Dokumentation u.a., dass das Feuchtigkeitsbindemittel in den Windeln beispielsweise auch zur Begrünung von Wüsten in Spanien eingesetzt werden könnte.

Unter anderem erwähnt er auch, dass 2/3 des Kohlstenstoffs in den Böden vorhanden ist – und weißt damit auf das Problem des Humusverbrauchs hin. Brennstoffe aus Biomasse? Gerne, aber nur dann wenn für die Anpflanzung von Zuckerrohr – aus dem in Brasilien u.a. Bioethanole hergestellt werden – keine Wälder gerodet werden. So gesehen ist der ecosan Ansatz das fehlende Glied in der Nährstoffkette – Fäkalien und Urin werden entweder getrennt gesammelt und kompostiert bzw. als Dünger eingesetzt, oder zur Gewinnung von Biogas vergoren und danach vererdet.

Vor allem aber wird auch in dieser Dokumentation (siehe die andere aus den Niederlanden) deutlich, dass Umweltschutz und gutes Wirtschaften sich nicht gegenseitig ausschließen, sondern gut ergänzen können. Genau diesen Ansatz verfolge ich auch mit meiner Diplomarbeit zum Thema “sanitation as a business” – gute Sanitärversorgung bringt wirtschaftlichen Mehrwert und eben nicht nur mehr Würde. Alleine schon aus volkswirtschaftlicher Sicht ist eine durchdachte Sanitärversorgung (nicht -entsorgung!) förderlich – man denke an all die Menschen, die aufgrund von Krankheiten (hervorgerufen durch mangelnde Hygiene, Toiletten, etc.) nicht am Arbeitsleben teilnehmen können. Dies betrifft alle Menschen auf diesem Planeten.

Unser kleiner Studienstandort Suderburg wird in der Dokumentation übrigens auch erwähnt. Und auch hier zeigt sich, dass Suderburg eben nicht nur im Wasserbau einen guten Ruf hat, sondern auch durch Experten wie Braungart überregional bekannt gemacht wird. Bleibt nur zu hoffen, dass die Kollegen vor Ort die Chance nutzen und ihr Studienangebot dementsprechend anpassen.

NUTEC – cradle 2 cradle fair

I’ve just come home from attending “Nutec” today – an international congress and exhibition on “Nutec: Nutrients – Upcycling – Triple-Top-Line-Eco-effectiveness-Community” that took place right here in Frankfurt am Main, Germany during the last three days.

Nutec is all about nutrients that will remain in a biological or technical loop, or as the tagline on their website reads: “Everlasting Cycles: How Waste becomes Food”.

Nutec was partly organized by EPEA which is run by Prof. Dr. Michael Braungart – who is the B in MBDC (McDonough Braungart Design Chemistry) – an international consulting company that tries to a) sell the philosophy of the so-called Cradle to Cradle (C2C) concept and b) tries to achieve this by convincing companies to obtain a C2C certification.

closing the loop on technical and biologial nutrients

Since Michael was my professor at university and since I a firm believer in this philosophy of closing the loops (which is one of the reasons I started becoming active in the field of ecological sanitation), it was particularly interesting to see how this event was set up, where the aims are, what kind of visitors it would attract and what any possible outcomes are.

Those of you who frequently visit other green blogs like Treehugger.com, know that C2C is a “sexy” and already very popular approach at dealing with the protection of our environment. And those who have read McDonoughs & Braungart’s famous Cradle to Cradle book often agree that their idea of another industrial revolution actually is the way to go. Maybe not at once, but in small steps and by starting today. I have even convinced some older folks in the business who have a very green background of this new approach. Especially since this whole green movement has been active here in Europe way back in the 1980s when our US-American friends only had green flower people – so opinions on “what needs to be done” had already been settled, with the usual discussions. Unfortunately, green activists had in the past often only experienced a negative image, partly due to their bad rhetorics. You simply can not tell anyone he’s doing someting bad if your only solution is to advice him on doing less (bad things).

McDonough & Braungart both achieved to market their idea of another industrial revolution, where they are asking companies to redesign their products into greener products. Products whose materials remain as nutrients and may then be reused for another purpose. I won’t go into more details here because I’ve blogged about this subject more than once during the last three years and there are various other resources online that give a much better insight into the subject.

14112008149
Trigema – Germany’s famous manufacturer of clothes who produces compostable shirts right here in Germany. The CEO of Trigema was present at their booth and really impressed me. Talking about Corporate Social Resposibility – big up for Trigema!

Back to the Nutec exhibition: this year’s event was a trial set up by EPEA to see / test how the public and international scene reacts. Messe Frankfurt, the world’s largest trade fair organiser, actually accepted a loss of 1,2 Million Euros to host this event – provided that EPEA/ElcaMedia continues to invite to another Nutec conference & fair, maybe next year in Hong Kong.

And this is what it was all about: an international event, hosted to pool interested visitors and their contributions, with about 60 exhibitors (this time only) that showcasted some of their ideas and approaches. And mind you, the idea behind all this is not to display eco products, but instead show the world that a better world is possible with economic incentives. After all, no company in this world will change its products only because of some environmental concerns. Instead, there’s money to be made out of this – analyzing your material flow streams and processes will help you (as a company) to save on lots of hidden costs you may not have been aware of. So instead of telling companies to stop polluting the environment, these guys invented the C2C certification which provides a detailed analysis of production processes and shows them a way forward.

14112008150
Backhausen – an Austrian company producing returnable fabrics. These guys were certified with a GOLD C2C certificate for their products.

The C2C certification has in the last few month also received some criticism online, especially as portrayed in this story on FastCompany last month. Despite of some personal resentments some CEOs may have with MBDC, the C2C certification is a smart way to cash-in on environmental protection, as it helps everyone involved.

For some reasons, which may also include this 49-minutes long documentary on MBDC, the C2C philosophy has become very popular in The Netherlands lately. It probably also is one of the reasons why Nutec this time attracted many Dutch exhibitors – green start-ups that are often looking for investors and who have some very smart ideas.
Braungart is a German though, and when I look back at university, I think I am save to assume that only a handful of students really understood his concepts and the importance of his message. It’s like the prophet who’s an outsider at home. I blame this on the German culture, and often wish my fellow countrymen here would be much more open to new ideas and willing to take more risks. So it’s very nice to see the Dutch side being so open to his ideas. We urgently need much more of this enthusiasm in Europe.

Other interesting exhibitors included:

14112008152
Nike – with a small booth displaying their shoe recycling concepts.

14112008154
These guys from Austria run a networking agency and set up a pilot project in the city of Graz where they managed to obtain funds from the European Union that helps them turn the city centre into a greener place. Simple, but smart and making sure to use what’s available (the EU has these grants + there’s a whole industry busy trying to apply for these).

14112008155
XeroFlor – these are the guys that provided the green (grass) roof to the Ford Rouge Center in Dearborn, Michigan, USA – the world’s largest green roof, covering 46,500 m² and thereby protecting the roof from heat and cold, improving the interior climate, saving on heating energy and offering habitat for smaller animals and plants.

I recently visited a friend who lives in a green roof building. If I ever manage to build a house one day, I’ll try to get my hands on such a roof. It’s just awesome! Didn’t ask for a price though.

14112008158

Ron from Redwood Renewables in California who’s offering solar panels integrated into roof tiles. “Redwood has developed the first disruptive environmentally friendly, chemical free, patent protected technology that can inexpensively recycle waste elastomers (tires) into devulcanized rubber high quality integrated solar roofing tiles and molded consumer end products“.

Told him about solar systems being in use in rural Kenya and how popular the system already is over there. For a typical household of 4-5 pax, you’ll need about 417 solar panel tiles on your roof.

Ron is currently looking for investors.

(Funny thing is that I had read about his project before when someone had sent me a link to his one-paged website some time ago and upon seeing his logo (!), I instantly remembered the link from the other day. It’s a small world :-)

14112008160
The famous Herman Miller collection must not be missed on this event. Comfortable and well-designed furnitures (and lamps, visible in the background) that make the difference. The materials used on each chair have been reduced to a limited selection and inspected for their toxicity. That’s the kind of chair you’d want to have for your office. Or?

14112008159
Some other crazy Austrians who invented this new show concept consisting of three different parts. The company name Wexla apparently is a joke on the word “Wechsler”, which would prolly translate to something like “exchangeable”. And exchangeable is what their shoe soles are.
These are prototypes, so don’t be fooled by the somehow strange design.

The idea behind this obviously is to provide exchangeable shoes to customers. I’ve even seen another Dutch company offering a very very nice laptop bag which can be rented for a period of three months and then returned. Could you imagine renting consumer goods instead of buying them? Well – that’s exactly the scenario we’re talking about here. Imagine your desk at work being occupied by someone else so you’ll have to work on another desk. How would you feel about that? Are human beings ready to accept such new habbits?

I tend to compare that with the YouTube Generation that stopped buying complete (music) albums and instead downloads single tracks online. Because it suits their needs.

14112008157
EcoWorx – another US-American product line the “Environmental Protection Agency (EPA) awarded the Presidential Green Chemistry Award for its environmental and performance benefits”.

We walk on carpets almost every day and inhale the abrasion. Think about it!

14112008161
A talented industrial designer at VelopA-Citystyle developed this new bench system created of two different materials, which is currently waiting for an official Cradle to Cradle certification. Appart from the green cover in this 1:2 scaled model above, “the bench is made from one piece of steel, without nuts and bolts, and is less vulnerable to vandalism and damage”.

That’s one those moments where I think: damn, I should have studied industrial design! :-)

14112008153
And this idea, ladies and gentleman, is one of the craziest concepts I’ve heard of lately. But a very good one, indeed.
What you see here as a scaled egg model, is supposed to become a comfy building for expecting mothers who want to give birth to their children in a much better, eco-effective environment. It’s a new type of childbirth centre, so urgently needed in Europe because birth rates are alarmingly low these days and in some European countries, giving birth is only possible in hospitals (and not at home, where you’d probably feel more comfortable). Once investments for this project are secured, they will try to build the first project in Spain.
Obviously, I couldn’t resist telling them about urine diversion toilets that would add a greener side to their sanitational facilities. :-)

————–

These are just some of the exhibitors, and there were only 60 around this time. Maybe there will be 200 next time – featuring innovative products from toxic-free cleaning detergents, healthy toys to edible fabrics and cleaner toner cartridges. Who knows? Everything is possible if you start analysing the products that surround us and realize how much we’re currently poisoning ourselves.

Interestingly, we saw a lot of (industrial) designers on this event – as opposed to traditional engineers which is what you’d prolly expect from an engineering perspective. But then – these designers are the ones to create the demand side, the ones who will have to ask for better materials.

It will be particularly interesting to see where we are in let’s say five years from now – what kind of products will have changed and found their ways into our daily lifes. What seems obvious to me is that C2C is a great marketing tool to promote innovative products for a better world. Oh, and there’s lot’s of money involved.

When will we see the first African C2C certified product?

[n.b.: Talking about environmental matters – what do you do with all these brochures you normally pick up at fairs? Read them at home and then throw them away? Many of the above mentioned projects have interesting brochures but still lousy internet websites. How come? I actually prefer a good website to obtain the relevant information instead of a papered brochure….]

JKE is GTD, part 2

Following my first prototype for an improved X17 organiser and a stolen parcel that was later on found soaked in the shrubbery next door…

erstes-paket

…I eventually managed to modify the ordered Texon-based X17 timer according to my needs.

306 aintro

As you may remember from my first post on this, X17 is a small company based in Saarbrücken, close to the French border, that also produces the X47 system – an advanced organizer system based on a spring-load mechanism that substitutes the “six-ring loose-leaf binder system” as seen on all other traditional filofax system. Filofax are nice, but! they waste a lot of space – as opposed to these X17 planers that on one hand offer the full space of a normal A5 (A6, A7) note book, and on the other hand are still exchangable. Obviously, it was time to send my filofax into early retirement and put my hands on a better system. I am not saying that X17 is the best system out there, but the best alternative I’ve come across so far and one which is also affordable: the timer itself costs 14,95 EUR in it’s cheapest version (hard paper oder Texon cover).

While waiting for the parcel to arrive, I had already made some plans on how to modify the system, e.g. include side pockets for important stuff and also add a few coloured strings that I can use as bookmarks. Simple modifications that just add user value to this already smart system which is btw based on elastic rubber as the binder mechanism.

So this is what I did with my new Texon-based X17 timer:

SANY1673

I first sawed the bookmark strings to the back….

SANY1674

…where you can already spot the distinctive “half holes” at the side which provide stability & guidance to the rubbbers…

SANY1676

…and fixed simple side sleves inside.

SANY1678

Please also note the pen holder at the right side which is very important to me. I prefer fountain pens btw, and the paper calendar inside is strong enough (80g/m²) to withstand the ink (an important detail!).

SANY1680

Next task was to add the back cover, whereby I had make sure that I just glue it to the back (outside) cover and don’t use any visible seams.

SANY1682

I used a screwdriver to squeeze the remaining cover behind the side pockets inside.

SANY1681

Now, as you can probably see from this direct comparison between these two X17 timers, the half holes were missing on the modified Texon-based version, but it still works because these rubbers have enough tension to find their own way into the material.

SANY1690

SANY1689

This is btw also the very reason why I went for the Texon (= soft material, right) version instead of the hard papered version as pictured above (left): the cardboard version only provides three holes, thus only three “rails” for rubbers, whereas the soft Texon version offers 4 holes. Unfortunately, this isn’t indicated on their website (yet – I guess I am the only freaky customer who further modifies his purchases and then blogs on them like a little kid :-).

I’ve btw given the cardboard version to my wife who already loves this system (she also only had a filofax before..).

SANY1686

SANY1688

Now, can you see the difference between the conventional filofax system and my modified X17 timer? I’d say it just rocks!

More space also means you’ll have extra room for weekly notes – which is very important for a proper management and substitues the many post-it notes that used to fly around.

SANY1696

all three versions directly compared: cardboard X17 for three A5 booklets (left, below), old filofax system on the left and my modified X17 organiser containing four A5 inlays.

SANY1697

Et voilà , my very own new timer that provides enough room for notes, keeps them ALL in ONE place, has bookmarks, two side pockets that contain extra stuff and a pen holder for my fountain pen.

This is the system I always wanted to have.

Verdict: If you’re not that happy with you existing Filofax system, X17 provides an interesting and affordable alternative. If you want to spend more money, you can just as well go for the X47 alternative (which is really sexy and has a beautiful finish).
I would also like to recommend the RoterFaden system, which in my mind is a bit more jua kali and maybe more practical for those who usually keep a mixture of notes inside their timer. I prefer the X17, though.

It would be interesting to know if there are any other, papered organisers out there that provide similar comfort. If you know of any, pls feel free to drop a comment here. Thx!

P.S.: It would also be interesting to know if a franchise/spin-off for the X17 could be arranged with African makers, e.g. X17 covers produced in Kenya with natural materials that could be certified with a Cradle to Cradle certification and then equipped with these high quality inlays from Germany. Ah, I guess it’s a matter of import taxes and maintaining quality standards among others, but still – the money is on the paper content, not the covers which are only purchased once. Or? (Eurogadget vs. Afrigadget?).

the perfect N95 headset

The Nokia N95 has been on the market for quite some time now (March 2007?) and if there’s anything I always wanted to change about it, then it clearly is the inappropriate headset it came shipped with (pictured below).

0dfa 1

The HS-45 headset with its AD-43 remote control unit failed to work after 4-5 months in use, so I went out and bought a few ofter solutions that never really performed the way I wanted it. Also, Nokia never really delivered a better solution, but instead kept on producing other unsatifying headsets.

While reviewing the Nokia E71 business phone that came shipped with the HS-47 headset as well as the state-of-the-art BH-903 Bluetooth Stereo Headset (for review), I quickly realized that I would want to have something similar to the HS-47.

What I needed to do was to merge my Sony MDR-818 earphones with the HS-43 headset I had bought via eBay some time ago. After all, what I need in a working wired headset are the following features:

  1. shaped earphones (like on the MDR-818 or the BH-903)
  2. an angled 3,5mm plug because the audio/video jack is on the side of the N95 (contrary to many other current Nokia phones who have it on top)
  3. a microphone located at the mouth and not on the chest
  4. some sort of volume control

So there I went, cutting the 10,- EUR Sony earphones into pieces and opening up the control unit on the HS-43…

SANY1238
some of the tools: a soldering iron (maybe not this Weller as it takes ages to heat up), old Sony MDR-818 earphones, Nokia HS-43 headset

SANY1227
HS-43 control unit opened up

SANY1252
unsolder L+ / L- and R+ / R- to remove the existing earphones + also remove the brass clip on the cable

SANY1253
trim the “new” earphones to the desired length and solder them onto the PCB, refix the brass clip to provide a strain relief on the cable (important!)

SANY1272
Et voilá – JKE’s own headset for the N95 that fulfills all the open issues I ever had with other headsets. Nice!

@ Nokia: PLEASE change your headset policy and – if you don’t want to equip your shipped handsets with decent headsets due to marketing reasons – at least provide us with better alternatives. Headsets are a commodity, and will as such always brake at one point.

mobile blogging, part 3

It’s almost one year ago that I published three (1, 2, 3) articles on mobile blogging – and nothing has really changed since then.

Back in 2007, both the Nokia N95 and the Apple iPhone were released – two completely different phones that were only compared on numerous blogs due to setting new standards on each segment: the N95 being a true multimedia phone with a decent 5mp cam, 640×480 @ 30fps video (albeit a mono mic), a (slow) internal GPS module and a really nice multimedia player. With the latest firmware, it even plays flash videos (YouTube & Co.) and has different applications run at the same time (sort of multitasking). The iPhone on the other hand provided a compatible device that suits Apple users – a nice user interface and all-in-one device like the N95 which unfortunately still missed some basic phone tools (MMS, Bluetooth exchange, etc.). And although both phones aren’t the only cool devices out there, they sold quite well. Even if the iPhone doesnt feature all these special goodies the N95 comes with, Apple’s phone still has the best browser on a mobile phone.

screenshot0009

GoogleReader on my N95…

Back in 2007 I had bought the N95 because the music player on my Nokia 6230i had constantly failed (due to a bug in the firmware) and because I urgently wanted to have a new, sexy phone. Something that enables a better mobile blogging experience.

And that’s exactly the basic point here: until now, no mobile phone has actually delivered this *sweet mobile blogging* experience so far.

Back in 2007, I argued that it’s a software issue. And still believe it is. So instead of buying new phones, a systematic adjustment between the phone’s software (firmware & single programmes) and your blogging platform (WordPress, Vox, Typepad, etc.) comes into mind.

Sure, there’s this WP iPhone app some of us have tested some time ago, but still: it doesnt work that well, and it doesn’t provide a similar experience we’re having online on our laptop, surfing the net with decent browsers on bigger screens with full JavaScript support etc..

And this – I believe – is also one of the many reasons for the success of Twitter. Twitter just filled that gap on mobile blogging, phone manufacturers have failed on providing. Why? Because that special Twitter experience is the same whether you’re online via a browser window on your laptop, use it via an extra widget somewhere on the desktop, have it run as a stand-alone utility on S60 & iPhone platforms or just use SMS (for sending only, though).

You know I had a discussion with my Minister of Finance earlier this week on getting a new phone (again), and I had mentioned the new Nokia E71 and why it could be an improvement on what I am looking for (~ mobile blogging device). However, with the above mentioned discussion on mobile blogging being a software issue, I am rather confused now and think I should stick to my N95 at this point. Maybe wait for Google Android’s phone being released by the end of this year?

Another interesting developement since 2007 is the success of so-called Netbooks – which are lightweight laptops at 7″-10″ screen sizes, often equipped with an energy saving CPU, a solid state disk and enough flexibility to provide surfing the net, answering your e-mails and doing some other office work. Battery runtime still is an issue though, often only giving 2-3 hrs. Netbooks are currently sold for 300-400,- EUR in Europe and are small enough to fill that special gap the need for mobile blogging has created.

So here’s my conclusion: instead of waiting for the ultimate mobile web experience via a dedicated & maybe also expensive smart phone, I’ll bet on another setup: ppl – especially those in need in a rural Africa – will imho be introduced to the combination of basic GPRS & UMTS (3G) phones, hooked up to cheaper laptop computers such as netbooks.

Not today, not tomorrow – but maybe in two years time when basic netbooks wil sell for ~ 150,- EUR and will also be sold on the African continent in a big style. Why? Because a mobile phone is – although it is often shared with members of the extended family – still a device for a single user (despite of these new Nokias that come with multiple phonebooks). A computer though can easily be shared with others. Here’s what I had in mind:

Image1

Solar panels are already for sale in rural Kenya as well as simple GPRS-capable phones, netbooks could be equipped with a free & open OS (+ BT, serial port & USB cable driver package) and it would still cost below the amount you’d normally spend on a) getting a normal desktop pc online or b) a fancy smartphone that just still doesnt deliver the real web experience.

And the best part: this setup isn’t reduced to the needs of a rural environment, but also applies to urban areas in the US, Europe or Asia. In other words: if I had to do true mobile blogging right now, I’d go for this setup (ok, maybe without those solar panels).

Netbooks are what Twitter is used to be to SMS: added value.

High Capacity Solar Charger Battery by Chinavasion

chinvasion-CVSBT-5504-7-computerx

 

Chinavasion has this new “High Capacity Solar Charger Battery for PC Laptop + Mobile Phone” for sale which looks quite promising in terms of it’s 20.000 mA/h accu – enough to feed your laptop’s battery.

Recharging the internal battery of cells (yeah! :-) is said to take around 3h @ AC and 8-10h through the use of the solar panel. What irritates me a bit is that on their website they are talking about a monocrystalline solar panel type, although it obviously is a polycrystalline type? Anyhow, an interesting alternative for ~ 96,- EUR. Let’s see when this will hit the European market (soon?).

I am still dreaming about a foldable solar panel that I can put on the cover of my 15,4″ HP nx8220 laptop and that will recharge a 2nd battery pack in an unused space, e.g. the media bay that currently hosts the DVD burner. Unless someone comes up with a much better (slimmer) rechargeable battery system, I am currently more interested in devices that generate power instead of just storing it (mechanical, solar, …. devices vs. NiMH/LiOn/…battery storage systems).

A sustainable power supply + decent bandwidth = JKE happy :-)

Make Some Green…

makesomegreen

The goal of the competition is to promote upcycling by encouraging the use of wasted materials to generate innovative designs and redefine the standards of environmental sustainability by fostering balance between conservation and development.

Despite this rather unfortunate phrasing ;-), there’s a very smart upcoming competition promoting the upcycling ideology (waste = food). Nice!

It is so amazing!

Now where are these guys like Mubarak Muhammad Abdullahi or William Kamkwamba to take over? Oh, and check out this Phun version on YouTube.

Next: a wind-powered commuter train supplying Nairobi’s CDB with Githurai?
No, seriously, someone needs to turn these mechanisms into an Afrigadget asap!
