Last night I uploaded my answers to the questions in time and provided additional material. However I wasn't able to update the public page above since apparently the editing feature was blocked. Now I can see the edit feature again. I will make sure to update the post ASAP
Hi Kate Rushton , thank you very much for your suggestions, I found them very inspiring. I plan to answer all your questions in the design refinements deliverable I am currently working on. If any question arises I will surely get in touch!
Hi Bruno, I like the idea and I also considered something similar. Perhaps turning caps into functional products could be challenging due to their structural integrity (I am thinking about a broom sticks, plastic structures, water hoses etc.) But definitely, even if just for recycling purpose, being able to combine caps together to create a bigger objects will increase the likeliness of them being properly sorted and recycled!
