Idea Title

Cornstarch Cup, 100% Biodegradable, Leak Free!

Idea Summary

The regular aesthetically pleasing cup will be 100% Biodegradable through the use of cornstarch as material, both body and lid. The consumer will still be able to enjoy their beverage without leakage

Please include a visual (can be either 2D or 3D) representation/prototype of your concept. (required)

Using the material polylactic acid (PLA), which is made from fermented sugars, usually from cornstarch, the cup will be 100% biodegradable which is important as it in turn is environmentally sustainable. When disposed of the cup will break down into carbon dioxide and water within several months. It is easy to produce, cheap, and can be transported easily.  Corn is the least expensive and most abundant source of commercially available sugar.  There can be minimal expense to the aesthetic of the cup, allowing users to feel more comfortable with the change.

This solution addresses which of the following:

  • Hot / Cold Fiber Cup
  • Cup Lids
  • Straws
  • Cup Liner
  • Some of the Above

How is your concept recoverable?

It is 100% Biodegradable.

How have you incorporated additional sustainability attributes (beyond recoverability) into your solution?

Easy to produce and cheap. Using Corn sugar is better for the environment than trees and plastic.

What regions do you plan to address with your solution (and how will you accomplish this)?


Describe your target market. Who will benefit from your product?

Not only will the Australian general public benefit, but the recycling plants will benifit as they will no longer have to sort through the current plastic lined cups (as they are non-recyclable), as well as the ocean where many of the cups and straws end up in Australia.
