Introduction
Today, Plastic is one of the most used materials in the world due to its versatility and low manufacturing cost. It is also one of the most harmful in terms of biodegradability. We throw tons of plastic away yearly and end up in landfills – they can last for hundreds of years before biodegrading. Tons of plastic are thrown away yearly, end up in landfills, and can last for hundreds of years before biodegrading. It is composed of petroleum-based compounds that release harmful gases during the degradation process.
Why Hemp Bioplastic?
- We can grow Hemp naturally at a cheap cost. It takes about 3 months to fully grow.
- It also reduces the amount of waste material while stills providing a product that allows the same benefits.
- The presence of oxygen and nitrogen in the natural polymers can be broken down by microbes like bacteria, and fungi (mushrooms).
- It includes a carbon-negative cycle. Carbon negative means, in effect, that you emit less than zero carbon dioxide and carbon dioxide equivalent (CO2e) greenhouse gasses.
Methodology
1. Ground hemp into powdery substance via food processor (grinder)
2. Extract cellulose using Acid Hydrolysis with Sodium Hydro-oxide(NaOH) aka Caustic Soda and Sodium Sulphide(Na2S)
3. Perform Xanthation process: Vaporise the cellulose with Carbon disulphide which will create a viscous material.
4. Store it to freeze for 24 hours.
5. Pour it on a slide
6. Treat it with Ammonium Sulphate, Sulphuric Acid and Glycrien Solution
7. Air dry for 3 days.
Result
Styrofoam textured sheets are ready on the third day of air drying. The material is lightweight and foldable.
