Some of the algae samples were kept for later use, and the rest were left outside to decompose.

Check out the continuation of this project with Green Cardboard II.

We realized that dried pond algae has material properties very similar to those of cardboard. We made two small boxes with minimal processing as a proof-of-concept for the material. 
Using algae as a substitute for wood pulp in paper production has many benefits:

  1. Using wood pulp is very energy-intensive

  2. Relying on wood can accelerate deforestation

  3. Trees take a long time to grow

  4. Algae grows very quickly

  5. Cardboard made from algae can be biodegradable

  6. ​Cladophora algae is an invasive plant

  7. Removing algae from ecosystems can mitigate eutrophication
