1. Compost Accelerator Team 9: Jorge Ramirez Stephano Salani Eric Zuniga Advising Professor: Dr. Kuang-Hsi Wu

2. Problem Statements  Increase the efficiency of organic waste management  Accelerate the decomposition of biodegradable waste into useable compost  Produce an attractive product for the growing “green” market

3. Solution Concept  A device that converts biodegradable waste into compost.  Compost – Organic fertilizer that is rich in nutrients  Vermicomposting (use of worms) will be enhanced through mechanical control systems.

4. Project Goals  Minimize household waste  Efficiently decompose bio-degradable waste  Cost effective and suitable for home use  Marketable

5. Commercially Available Compost System  System is being tested  Lack of mechanical components  Potential to increase efficiency

6. Design Parameters Prototype Design must: o Inexpensive, overall o Easy to use o Compact in size o Work autonomously o Work cleanly o Not attract unwanted insects or pests
