The TDK Designer Solar Panel. Picture by Engadget.

A good example is the TDK solar panel design that has different draws and patterns on it. It could be argued that this device may not be as efficient as a normal solar panel but making the solar panels attractive could do a lot to make the adoption of the technology faster; and that’s important. The real potential in this technology is for use in big surfaces (like buildings) and maybe not just as personal devices.

Docomo Touch Wood phone

Many could think that the Docomo Touch Wood phone, made of wood, looks good. As this is avoiding the use of traditional plastic this design could be going in the right direction. In comparison to bio plastics, wood could last longer and, eventually, the case box could be reuse. Can we imagine updating the inner part of a wood phone instead of throwing away the whole thing?

Novothink solar charger for iPod

I am a little bit more skeptic about the greenery of this specific-use gadget. This is yet another gadget and the amount of resources needed to build it is probably big (water, energy, plastic, etc.). This is a big question we should ask ourselves as designers if we design a product to be marketed as “green” or sustainable: with this thing, do we save resources or do we consume more out of the planet?

The Samsung phone made of corn

Bio plastics are a very interesting material, still their advantages are questionable. They could be made of different sources, like potatoes and corn, fact that makes them not only less polluting but also morally incorrect (many people would argue). Of course that might depend on the efficiency of the producing of these materials: how many potatoes do we need to produce a kilo of bio-plastic?

You buy them for a reasonable price (say, up to 0.50 €), you can use them for a long time and when they break you can exchange them for a new one with no additional cost. A good deal, I would say. But it is 10 years now and we still have an awful lot of plastic bags choking our environment.

One of the reasons is that many shops still offer the “normal” one-use bags for free parallel to the recycled ones, so many people save the penny. Many of the customers that do care and buy the recycled bag regularly forget to bring it to the shop, and when they have a collection of 10 recycled bags at home they just don’t care anymore and take the ones that are for free.

Many shops don’t even have the alternative and provide only one-use bags. In fact, my experience shows that in small stores a little conflict takes place when I try to explain to the person behind the counter that I don’t need a bag.

Some people have been thinking about this and have taken action to fight the plastic bag problem:

Compostable plastic bags

You have probably heard about these already but they are now spreading fast in the market. Spain is the first plastic bag producer in Europe and it will forbid non biodegradable plastic bags by 2010, so the whole industry is rushing to adapt to the new situation.

Aldi Süd, a German Supermarket offers now reusable compostable plastic bags. Alternative to these they offer recycled plastic bags, which cost a quarter of the compostable ones. Still, it is a start. Interesting about this bag in particular is the material it is composed of. “Ecovio” is a blend between a biopolymer made of corn starch and a polymer made petrol. The petrol polymer fraction has been processed so that it is in fact compostable. Petrol made biodegradable, not bad, uh?

Tassenbol

This is my favourite aproach so far to tacle the problem. I first saw it in a supermarket in Amsterdam and found it fabulous. It is just a bowl where customers put the bags they don’t need anymore and where they take them when they need some. Simple, effective.

The only real drawback I found is, that corporate image issues could interfere with the concept. Including a tassenbol in a shop implies promoting that customers leave the shop wearing any brand in their bags, including those of the competition. After researching a little bit I surprisingly found out that many supermarkets in the Netherlands have already the tassenbol in their subsidiaries, so they must have found enough advantages in it to compensate. Lets hope shops in the rest of the world join!

All conferences were planned on a symposium day and the whole event lasted about eight hours. The quality and background of the speakers was as motley as it gets. It started with two so called "institutional presentations" by the Taiwan design Center and the "Metropolitan Design Center of Buenos Aires". Promotional videos of both places, a lot of charts and never ending text on the projector. No real talk about design there, even though they repeated the word until it lost its meaning. I suppose they paid to be there…

Within the "Alternative strategies" block Yuri Suzuki and Hiromi Ozaki talked about their "Cybernetic love: future sex project". These people analyze the Japanese society habits from all angles to get to the conclusion that sex practice is integrating elements such as virtual lives and places, electronic pleasure gadgets, robots, etc. till an extent, that a human partner is no longer the preferred alternative. This project is financed by Tenga, a company that develops high quality adult toys. I must say they have a point, check out their promotional video;  if this is not user experience design, I don’t what is!

Ronen Kadushin presented "Open Design" and his way for design to evolve if we really want good design to surround us. We all have seen how open source software gives the best results, now here is a way to do basically the same but with product design.

Interesting lectures of the block "Sustainability": Ralf Ketelhut from Stoffstromdesign let us know what really happens when products are waste and made us aware how harmful coatings and pigments are in our product. We also saw an example of a very nice nearly 100% environmentally friendly wallpaper. Key to success they said, is to go to the manufacturer, talk to him and find a different way of doing things.

Probably the best example of good innovative design was given by 2012 Architecten. They presented some realized projects in which they rather than recycling they reused material that was considered waste. They identify a source of large quantities of waste material in good conditions and they find a way to use it.

One of their requirements when reusing materials is to take them as they are and add no processing to them when possible, this way it is economically and environmentally worthwhile reusing. Some of these projects are an espresso bar made with used PVC windows and the duchi shoe shop, where car windows make the shelves.

Jurgen Bey gave a nice lecture about how we approach design problems and what could be the role of design in the future. A pity that I didn’t record it… there is a good summary of it in design.nl

One: reduce waste by not designing it.

my contribution to paper waste

This week I came across a very nice piece of crafts made out of the core of toilet paper rolls. Then I stopped to think about it and realised that we can found very often coreless paper rolls in public places. I suggest, let’s not take things for granted and question why are they the way they are. Paper rolls were initially conceived with a core, because at the time the technology wasn’t able to do it otherwise.

Marriott Hotels are introducing coreless paper rolls by the end of 2009, they have a brief comment about it on their website.

Two: design reusable rather than disposable.

A significant fraction of our domestic waste is just disposable products. Reusable products minimize waste an costs. A good example for this is my last acquisition: the menstrual cup, a gem. It is a silicone device that substitutes sanitary towels an tampons. Since I have it I have saved money and literally stopped creating waste.

Three:  consider the whole material chain your product will go through.

One of my favourite design classics is the moulded pulp egg tray. Made of recycled material, reusable, recyclable, cost effective, resistant.

eggs from the supermarket

Moulding technology keeps improving and now it is not only about egg trays but any kind of protective packaging.

I received a packet last week and I tried to reuse the packaging chips that came with it for some domestic purpose. What a surprise when I realised they melted under water! they even somehow smelled of crisps…

 starch chips melting away

After some research I found out there is a wide range of packaging chips made of  vegetable starch in the market. It happens to be an envionmentally friendlier alternative to the plastic ones, also fulfilling the product requirements.

I didn’t know it, but bamboo is still used for scaffolding in many countries in South-East Asia, and even for skyscrapers. It is resistant, quick to assemble and disassemble and it also "tells you in advance" when it is going to crack down, not like steel structures (at least that is what its supporters say…).

Well, bamboo is getting into a lot of new applications. You’ve probably heard about ASUS new nature friendly laptop; eventually only a part of the housing will be made of bamboo, but it was a nice try. There is a lot of other interesting approaches such as Amadana’s bamboo earphones, all kinds of speakers and modern crockery.

Adobe is basically a mixture of clay, sand and straw and it used to be a construction material for modest houses.  At some point it fell into disuse, being substituted for other materials, but now it has gained interest again mainly because of environmental reasons;

Its good thermal and insulating properties (passive solar architecture).

It is a natural resource that goes back to nature at the end of the cycle (though I´ve discovered some new applications in which they mix it with asphalt).

Its manufacturing process is clean and simple.

It is usually a local resource, so minimum transportation is required.

A traditional local industry is revived.

When we design we are often limited by current conventions, and when it comes to material selection many of us designers tend to go for a safe choice. Experimenting with unconventional materials can turn into a nice new product. Here is an ICSID article that approaches the issue from a wider perspective.

Drink packaging can go from the most economic even minimalistic Asian design approach, in which all we have is a bag and a straw, to the becoming-standard western wax coated paper cup. These are replacing the plastic cups not because of economical reasons but because of environmental issues. That is also why we rarely see warm takeaways in expandable polystyrene containers.

So, if we do are starting to design thinking of environmentally friendly products, why not go a step forward and change disposable cups for permanent ones? After all, the really effective solution to reduce waste is to avoid its production. On top of it there is the significant amount of energy saved in the whole process chain. Through a good product design strategy we can find a new solution for an old problem.

Refund systems have always been around; bars still return empty bottles and cases to the provider. Public transport systems in some cities don´t provide paper tickets, but magnetic cards that are returned after use to be reused.

Germany has succeeded in establishing a standardized refund system for plastic and glass bottles and has almost eliminated the use of cans for beverage in the German market.

Big fast food chains are in fact a very suitable environment for a cup refund system; a titanic number of cups used every day, efficient sharing of resources to reduce costs, multiple branches to return the used cups. In the mid term, it would even be a cheaper solution than disposable cups, not to mention the positive impact on the image of the brand betting on such an initiative.

Design vs Art proposes a cup refund system, integrating collection, washing and handling of cups. Its user oriented design provides easy and time-saving handling and attractive integration in large fast food restaurant chains.
