Time is not recyclable, but the way we record it could be recycled. This time, a new way to record time was designed - Rolling Time, a desk calendar which allows us to track dates in a sustainable way.
Different from paper calendars, which need to be changed every year, Rolling Time is entirely made of casting aluminum. It's a way to avoid wasting paper resources and we can use it every day, every month and every year.
​Rolling time consists of three parts, one date board with month and weekday groove, one hexagon month gear and one Heptagram weekday gear. For tracking time, you just need to roll the weekday gear everyday and roll the month gear every month, which is more remarkable than digital calendar or paper calendar due to interactions.

The initial idea of this project is to convert linear systems into cyclic systems. Sustainability is a constant concern of society, especially when it comes to resources and energy. In this project, firstly a linear system was identified - we consume a lot of paper and after the use they just go to waste. Even tho we could recycle paper, the energy and the resource consumption is still huge. 
My goal is to design an alternative to the linear system in order to make it cyclic, which means the resources or energy used in the production/product can be reused or repurposed. I find an everyday used paper product - desk calendar, and designed it with cyclic thinking - in a way that we can use it every year without changing and made it by casting aluminium.
what if
What if there is a kind of desk calender that we can use every year, every month and every day...
sketch model
Firstly, I tried to make a sketch model that we could choose month and weekday and put it in specific date groove.
Then I refined the shape to make it more suitable for desktop and more interesting to use
3D model pattern
The prototype of Rolling Time is made by aluminum casting, since it's a 100% recyclable material and the manufacturing process is relatively simple and energy-saving. the 3D model pattern was made. to make the product lighter and more material saving I refine the backside of the 3D model. (picture to the right show the dimension and backside design) 
The 3D model was printed and fixed so that it could be used as the pattern for casting aluminum. 
casting & afterwork
The pattern was sent to the factory Rosengrens metallgjuteri in Malmö and an aluminium casting piece was finished. 
After that I did some afterwork including a lot of sanding and polishing, as well as glassblasting and so on to make it a nice finish.
