Recycle Plastic to make Mesh for Plastering
I made my whole house out of recycled nylon fishnet and cement. The tuna factory where I got the free fishnet moved off the island, and I have no more source for plasterable plastic mesh material. I like plastic mesh because it doesn't rust. Recycling some of our plastic trash, which is a huge world-wide problem, would be great. Furthermore, given plasterable trash sacks one can make "trash rocks" ( https://www.instructables.com/id/TRASH-ROCKS-Eliminate-Unrecyclable-Trash ). One can build with trash rocks; putting unrecyclable trash to good use as fill material inside the trash rocks.
If somebody could come up with a way to melt down and somehow convert plastic into mesh material, it could be a big step toward putting our trash to good use. Mesh in the form of ready-to-use trash sacks would simplify the making of trash rocks. In flat sheets, the mesh could be used to make walls, floors, and roofs.
Fishnet stretches in all directions, so it is good for making dome shapes. Some meshes are more rigid and are only good for flat projects, or cylinders. If the mesh was more rigid, one might buy ready-made, light-weight forms for things like outdoor furniture, take them home and plaster them on-location.
Someone more chemistry oriented than I am might be able to figure this one out. It seems to me there might be a lot of commercial potential in this, too.
