  1. Plastic Bag Recycling Rope Weaver Hot Rods 2.009 RedA Team October 4, 2007

  2. Rope Weaver Rope Weaver Waste LDPE bags Light-duty rope • Simple weave connects bags • Rope jack twists together • Radiant heating fuses product

  3. Rope Weaver Technical Requirements Sustainable Energy Source: Charcoal Temperature to Fuse Bags: ~120C Temperature of Tubing: ~300C Estimated Heat Flux: 166.6 W/m2 Critical Modules: Rope Twisting & Radiant Heating

  4. Rope Weaver Critical Modules Rope Twisting • Demo Rope twisting easily modified for pedal power Figure: Schacht Spindle

  5. Rope Weaver Critical Modules Radiant Heating • Video

  6. Rope Weaver Optimization • Strands Per Rope: • Ease of Construction vs. Final Product • Flexibility, Strength, etc • Diameter of Copper Tubing: • Decreased diameter faster heat transfer • Accuracy of centering mechanism

  7. Plastic Bag Recycling Target Customer • Lome, Togo • Population: 850,000 • Specifically: urban slum Forever “…major source of pollution in virtually every country in Africa…” Figure: Nations Online

  8. Plastic Bag Recycling Customer Needs • Significant Reduction in Pollution “…the main issue is getting the plastic bags off the street…” --Meghan, IIJD Bag Recycling Client
