  2. The Problem • Makes up a very large amount of waste in terms of volume • Styrofoam does not degrade • Styrofoam costs $2,000 a ton to recycle

  3. Needs

  4. The Market

  5. Material Testing • Replacing blister packs • Drop tests in Sage • Possible Materials • Rice Hulls • Corn Husks • Puffed rice

  6. More Material Testing • Drop Tests • Results

  7. Models/Iterations • Soft Models • Corn Cakes • Rice Hull Mixture • Working Model • Rice Hull Mixture

  8. Experiments • Orthogonal Arrays to test parameters • 8 different mixtures changing • Flour level • Drying method • Baking soda/vinegar • Corn Syrup

  9. Measuring the Results • Measured Density • Weight • Water displacement • D = m/v • Comparable to Styrofoam

  10. Data

  11. Final Tests • Last Drop Tests • All eggs survived

  12. Our Product • Lightweight Packaging • Sturdy and Durable • Variety of Applications • Customizable Give • Inexpensive • 100% Organic • Created with Waste Products • Easy to produce • Decomposes with addition of water • Environmentally Safe

  13. Feasibility • 100,000,000 + metric tons of Rice Hulls produced annually • Main Rice Hull mills in Louisiana, Texas, Arkansas, Missouri, Mississippi, Florida and California • Do not burn easily, therefore are hard to dispose of and considered waste • Although it is organic, been thoroughly tested and determined • Less than 3.23% moisture, much less needed to grow mold or fungi • 28 days fungi free test without use of fungicides or chemicals • Does not corrode aluminum, copper, or steel

  14. CAD Models • Designed packaging for USB number pad • Cost $954 to rapid prototype • No access to CNC Mill • Mold by Hand

  15. Production • Automated production could follow the same method we are using – there are industrial microwaves.

  16. Costs • Average ton costs $6 • 53 foot trailer can hold 24 tons of rice hulls and costs $15, $30, and $45 to move it 250,500, and 750 miles. • Possible transportation would raise $10.5 million for Rice industry and %15 million for transport companies.

  17. Patent Research • No direct competition • No similar patents using rice hulls • One other patent uses toxic chemicals

  18. Conclusion • Very competitive with expanded polystyrene • 0.109 g/cm3 compared to 0.025-0.2 g/cm3 • Cost ratio of 6.92:1 • Fully biodegradable
