Typical paper cups are not made from recycled paper. Instead, most cups are made using 100% bleached virgin paperboard due to FDA regulations and recycled paper’s lack of durability to contain liquid. Therefore, paper cups require a staggering amount of paper to construct a structure that is both FDA satisfactory and liquid-resistant. Considering, people in the U.S use 23 billion paper coffee cups a year and to make that many cups, 9.4 million trees and 363 million gallons of water are needed, paper cups better not be used.
Despite these environmental downfalls, paper cups are continuously used for their convenience. Carrying reusable cups can be a nuisance and these cups can take up a lot of space. On the other hand, Leaf cup provides a same structure and convenience as conventional paper cups, using a thin polyethylene paper, while significantly reducing waste. An user can easily carry this thin and light Leaf cup made of recycled cardboard paper that uses technique of honeycomb, which enables the cup to expand to form a cup, and starbucks only need to provide the polyethylene paper of a whole cup. Leaf-cup demonstrates a new realistic and convenient way to reduce paper waste and save trees without significantly altering a user’s behavior or habit.
Also, Leaf-cup further contributes in reducing the paper waste by eliminating the need for extra sleeve.
Leaf cup can be expanded to form a cup. Industrial Velcro attached to each end is hooked to sustain the shape. Industrial Velcro is easy to use yet strong enough that a two-inch square piece can support a 175 pounds person, and therefore definitely strong enough to provide hold a cup of liquid.

customers bring reusable supporting material while starbucks only provides disposable thin coated water proof paper. Inner material can be same material that regular cups use. but much thinner since it doesn't need a structure of a paper cup
Let's say regular paper cups need 5g of tree to build its structure + 1g coated thin paper inside for waterproof. Total 6g of tree will be wasted.
If customers carry leaf cup they don't need 5g for structure.
All they need and waste is 1g of tree and that is the part you can save tree while you don't have to sacrify too much of convenience or sanitary
thanks andrealimida
You are right and I appreciate it.

just a few questions that pass through my mind
i agree with Berkana's concerns
i think you should make a real mock up to see if the form works or not
the rendering looks great and very smart of you to use motion images
it really helps us to understand it better
i am a bit worry that with the leaf form, it may not close up properly and the bottom of the cup may be fragile or unbalanced when put on a flat surface
i like the idea of using velcro, yet that's only one of the solution
somehow, i don't feel velcro fits with honeycomb paper material
maybe there are more ways to attach both ends?
ex. experiment with other forms
or maybe the form doesn't revolve from one end to another
it could be pull up and push down?(vertical axis) a spring-like form?
which could also be easy to carry
i think the design/idea is great
perhaps the next stage is also to think about how would this work in real world
the marketing
what else could you add or take away to make the users want to carry this with them?
finally,
why will this design make change? can you take this further?
ps. i know you've already mention about the reduce usage of materials
keep up the good work!

have you prototyped and tested this idea?

I tried to make a honeycomb by myself but it doesn't look right, so I asked sample of honeycomb material for prototype.

I definately considered vertical axis.
(spring like? form )It is commonly used in many area such as camping water bottle. I think it is okay for water. But if it applies to coffee, it would be very hard to clean.
Thank you for thorough ciritique, emily.
