Welcome to the online platform where we are going to share all material that is coming available while circular redesigning a bunch of day-to-day product. In the second quarter of 2015 a motivated team of design students of the TU Delft in The Netherlands and professional designers are building inspiring circular design cases in a joint effort to accelerate migration to circular business. On this page you find the latest updates on the work. The following page tells you more about the context of the Project.


Bicycle lamp
Circo-150528-by-GraphicAlert-04 Many cheap bicycle lights are thrown out after use. When the battery runs out, it is often easier to buy a new light – they cost so little – than replace the battery. And it’s a pity, because the lights themselves can last much longer.

This concept offers a cheaper and more reliable way of lighting up your bike than “throw away” lights. The light includes both a red and a white LED so that it can be used on either the front or the back of your bike. When the battery runs out, you can exchange the light at a vending machine. The lights are charged up inside the machine and tested to see that they work properly.

In this ‘access model’, income is generated through charging the light. A deposit is paid as part of the initial purchase, which covers the physical cost of the light. When the light is handed in, the customer gets a new light for a small fee.

Circo-CDC-credit-Chantal-Bekker-05-low-res-683x1024 Hockey sticks are generally only used for a short while and are non-recyclable. Young hockey players in particular need new sticks regularly because they outgrow them or want another style or colour. The challenge with this circular product was to find a way to make length of use coincide better with the physical lifespan.

Hockey sticks can be offered every season via the ‘access model’. And the more battered the stick, the cheaper the rental contract. If your stick is too worn out for your league or you have grown, you can exchange it for a new one.

Children often want a new stick because they don’t like the look of their own one any more. Now, you can pimp your stick with a Sleeve. The Sleeve not only allows players to personalise their stick, but the sticks are better protected and last longer. You pay for your stick via a lease model, and each lease season it gets a new sleeve.

Circo-CDC-credit-Chantal-Bekker-01-low-res Kite surfers are conscious of the importance of looking after nature, and the ocean in particular. It seems strange then that they don’t consider this when it comes to buying gear. Kiteboards are used only for a short while because surfers’ needs change as they get better at the sport. As a result, the boards are often thrown away after only one year.

It is difficult to redesign kiteboards due to the type of material used and the technical specifications. Therefore, this concept focuses on providing an exchange service in the form of a monthly subscription. Kite surfers can use an app to track their progress and receive tips on what they can do to improve.

Each time a board is exchanged, it undergoes any necessary repairs and maintenance to extend its lifespan. Because the provider retains ownership of the kiteboards, there will eventually be fewer disused boards and they will last longer.

Circo-CDC-credit-Chantal-Bekker-12-low-res Refrigerators have a much shorter lifespan than necessary. This is because they break down prematurely due to poor maintenance or because they are disposed of to make way for a larger or smaller model, for instance. The appliances have an average lifespan of 14 years, even though they could keep going for decades.

The circular refrigerator concept comprises a set of racks in which the refrigerating element, available in three sizes, can be installed at an ergonomic height. If you move in with someone for example, it is very simple to create a bigger fridge. Energy use is limited by carefully categorising food that needs to be kept chilled. The fridge is easy to repair since the parts that require maintenance are readily accessible.

The appliance will be supported by a ‘stay-fresh service’, which will ensure that your fridge is always hygienic and well-maintained. Service technicians will pick up elements that are no longer required and, after a tune-up, they can be used for another customer’s refrigerator. Renting circular refrigerators out with a service contract means that profit can be generated over the product’s maximum lifespan and will prevent fridges being dumped prematurely.

Circo-CDC-credit-Chantal-Bekker-07-low-res Many people throw their slippers away when they get dirty or when the sole wears out – often, after only a relatively short period of time. And many people don’t want to spend a lot of money on slippers and so buy ones of mediocre quality. As a result, a lot of slippers end up at the garbage. But this could be changed, by altering the product and the mindset of consumers.

LOFS slippers were designed to provide a solution to this problem. The slippers consist of three parts: a good-quality sole and top, which are guaranteed to last for ten years, with two types of insert – one for spring and one for winter.

They are rented out in places where people are glad of comfortable footwear. For example, they can be offered at trade fairs where visitors have to spend a long time walking around in uncomfortable business shoes. Enthusiastic slipper-wearers can then buy their LOFS at the end of the day. Back at home, they can then order new inserts when the old need replacing. This extends both the quality and life of the slippers without the wearer having to spend more money on them.

Circo-CDC-credit-Chantal-Bekker-11-low-res Electronic waste is an increasing problem at music festivals. People bring speakers and big stereo systems to their camps, but many are left behind when the music is over. Tons of batteries and broken speakers is not very circular. This concept shows how a wireless speaker can look like in a circular economy.

The speaker has a simple, appealing and robust design where repairability and recyclability in materials has high priority. It consists of only a few parts and is designed to make it easily adaptable for future applications.

‘Soundvenience’ is a music service that gives participants at music festivals a more social, convenient and fun festival experience by renting out durable speakers with unique social features and with free charging included. A unique speaker design allows users to connect to other speakers through an innovative yet intuitive user interaction.

Circo-CDC-credit-Chantal-Bekker-03-low-res ‘Toothpace’ is a response to the plastic waste created by empty toothpaste tubes that are thrown away once the paste inside is finished. Often toothpaste tubes are discarded with leftovers of paste inside.

In order to avoid plastic waste and paste leftovers an edible packaging has been created for dosed “toothpaste capsules” made of sodium alginate. Since the capsules are edible, there won’t be any waste of plastic or paste in the environment.

‘Toothpace’ is meant to be a premium product that aims for a conscious target group that is looking for sustainable alternatives.

To create a sense of attachment towards the product and a as relative advantage towards competitors, the consumer can personalise his own paste through an online service, choosing from different flavours and ingredients. The paste is delivered by mail and is payed for with a monthly subscription.
