The Waste Stream Education Wheel was designed in the Humboldt State University Engineering 215 class to be an educational tool for use by SCRAP Humboldt. The wheel targets third through eighth graders, and teaches how three everyday objects go through the waste stream.


The client is SCRAP Humboldt (School Community Reuse Action Project), an up-cycling center based out of Humboldt County that implements education and affordable materials. This helps to promote their goal of environmentally sustainable behavior and creative reuse. In order to promote their values to the public, they seek a tool that they can use in their facility for educating the youth about the waste stream. [1]

Problem Statement and Criteria

The objective is to design an educational tool that informs people of the basic fundamentals of the waste stream and presents that information in an interactive and entertaining way. The criteria are neccessities to help find the best alternative solution for the client's vision.
Criteria Weight Description
Cost 4 The total expenses are less than $300.
Aesthetics 7 When anyone observes the project, the appearance is professional and unique.
Education Value 10 The solution provides information on the waste stream for K-8.
Portability 8 The item is able to be carried by one person
Safety 9 The project is harm free, with sharp items absent.
Ease of Use 6 A child can use the project.
Functionality 9 Is interactive and has more than one purpose.
Toxicity 5 The project is durable and has no toxicity.

Description of final project

The Waste Stream Education Wheel is an educational tool that teaches children about the waste stream. Its main focus is on three primary items; a gaming device, an aluminum can, and a t-shirt. When the wheel is spun, the viewing window reveals each step in the life cycle of the primary item seen on the wheel. The board is interactive, and will help kinesthetic as well as visual type learners. The frame of the structure is made of bamboo. Two of the wheels are made of plexiglass, while the third wheel is made of an upcycled record. The knobs are upcycled as well.


SCRAP Humboldt and local businesses donated many materials. The retail cost is based on prices from local stores.
