Technological Problem:

How to find a natural hard packaging that is biodegradable.

Function of Hard Packaging:

Hard packaging is used for storing consumable things in, such as food and drinks. These packages are often made out of plastic and polystyrene which are not environmentally friendly as they pollute our land and they aren’t biodegradable.



We found a design called WikiCell. This design mostly uses natural particles (with the exception of the synthetic biochemical polymer, chitosan, and the algae extract, alginate) to make a thin gelatinous casing that can hold liquid products. The WikiCell membrane is made from a combination of isomal (sweetener) or bagasse (a fibrous residue from sugarcane), alginate and chitosan. Shrimp skin (chitosan), is very similar to that of the WikiCell’s casing and provides a hard membrane sp that products may be packed to avoid breakage. Electrostatic forces hold the membrane together. These membranes have resistance to water diffusion. They also have adjacent shells which will allow the WikiCells’s to have stability over time. For different types of food and drinks, a wide variety of membranes can be produced. This will be done using a WikiCell Machine.

Most packaging is made from plastic, which is not biodegradable and just keeps breaking up into smaller and smaller pieces over a period of time. It also is made at the cost of valuable resources, example oil. WikiCells will allow food for food to be packaged in a fully biodegradable way and take away the oil-to-packaging process.
