  13. 13. Analysis Insights Video Observation Advantages in current scenario cheap use & throw can be carried anywhere by the user easy to pack, store and transfer because of thinness Disadvantages in current scenario paper wastage (non eco friendly) sauce undesirably mixes with other food like paratha need cardboard to hold it which is again non eco friendly Other A lot of discussion is associated with plates

  17. 17. Conceptualization Material
  18. 18. Conceptualization Material• Economical• Plates made of sugarcane bagasse is microwave and freezer safe, can be used for both hot and cold items• Sugarcane fibres have low density. So they are light.• handle hot liquids up to 220 Fahrenheit• Biodegraded in 35-40 days.• If burnt – no CO2 emission, could be used as bio-fuel.• Recyclable.

  28. 28. Manufacturing Making Plate• Fiber reinforced with thermoplastic matrix to increase stiffness• Polypropylene(PP) is the thermoplastic polymer used in this work, being a semi-crystalline polymer and an important engineering thermoplastic with various industrial applications, but it is also a commodity polymer by the low cost, low level of mechanical resistance, processing facility and larger production• The best molding process is the injection under vacuum, which leads to materials with homogeneous distribution of fibers and free of blisters.1 Pour two gallons of water in the rectangular plastic container.2 Place 1 1/2 cup dried chopped bagasse and 3 cups of water into the blender. Blend on high for one minute. Pour the bagasse solution into the water basin. Repeat the process one time.3 Use your hand and stir the solution in the plastic container. Evenly distribute the fiber through the water.4 Put the two parts of the deckle together with the empty frame on top and hold firmly. Slide the 8-inch edge of the deckle into the water next to an 11-inch edge of the plastic container. Slide the deckle along the bottom of the container until it is completely submerged.5 Slide the deckle back and forth along the bottom of the container. Continue the motion and lift up slowly until the deckle is entirely out of the water. Hold above the container, allowing the excess water to drain.6 Remove carefully the top frame from the deckle. Center and place the chamois over the top of the bagasse paper. Press the chamois lightly to begin absorbing the water on the bagasse paper. Quickly flip the deckle over so the chamois is on the bottom and laying on a flat surface. Gently remove the screen from the surface of the paper. Allow the paper to dry 24 hours before use.These papers are transformed into plate using vacuum molding. Paper is pressed and pressurized between male-female die havingdesired pattern. Multiple papers can be used to increase thickness
