Material Possibilities

After coming back from Costa Rica I made a mind map trying to organize my thoughts about the existing problems that can be addressed with the material I had created. My focus was on the weather conditions(insulation/building material), easy and fast production, replacing plastics in their lives..
The 4 options I came up with are Transportation(food container), Building material for houses, Hydroponics and Container for water. I would like to take advantage of the material's properties of being lightweight, water-resistant, floatable on water, (in the cases that it contains silica) bug repellant and fire resistant.
For transportation, I thought it could just replace plastic or raw wood as the material for the boxes that were being used.
For building material for houses, it could replace the corrugated metal sheets that are being used to build the walls for the houses. Instead this material could provide much better insulation while being water-resistent so the houses could stay safe.
For hydroponics, the flat pressed material can be used as the base which holds the plants. It could have holes which the plants can be placed on, and it could be floating on the nutrient solution.
For the water containers, instead of using plastic (possibly that have been in contact with toxic fluids) the community can build their own containers with this recycled material which is also lightweight and water-resistant.
