Idea Title

Invasive Innovation

Idea Summary

We will turn water chestnuts into a new cup that degrades better in the environment.

Company / Organization Name (if applicable)

Troy High School

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

Using recycled plant matter from an invasive specie of water chestnut, we intend to cast and create environmentally friendly and biodegradable cups for common use.

This solution addresses which of the following:

  • Reusable System

How is your concept recoverable?

Fiber cups today do not degrade in the environment. It takes many many years for the fibers to break down and be contributable again in the environment. With the water chestnut cups, we will help eradicate an invasive specie in America and help the environment.

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

Our base materials are based off invasive species. For this specific cup we are using water chestnuts that are harmful in many aquatic areas in America.

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

Water chestnuts are mostly invasive to the east coast of America including, but not limited to, Pennsylvania and Michigan.

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

This product is geared towards replacing the existing fiber cup. This product can be used by anyone who uses fiber cups. We are also intending to sell the cup to big companies for their employees' use.

What is the current stage of development of your idea?

  • Research & Early Testing

What are the biggest challenges you are facing today? What are existing gaps in your solution?

We are still figuring out how to access the water chestnuts and create it in a usable cup.

Mentorship Needs (please select up to 3)

Please describe how becoming a Top Idea will support the growth of your concept.

If our cup becomes a top idea, that will bring more attention to it, thus making our projected market larger. Also we will have more access to supplies and funding.
