### Tools & Hardware

- Plastic extruder (local models by Toan Nguyen)
- Shredder/granulator (for processing raw plastics)
- Industrial mixer (blend polymers at specified ratios)
- Heat gun or bending tools (for curved elements)
- Basic woodworking tools (drill, screws, clamps)

### Materials

- **Hard mixture components:** LDPE, HDPE, PP, PS
- **Soft mixture components:** LDPE, HDPE, EVA (e.g., recycled flip-flops)
- Additives: Shrunk EPS, shredded PET, aluminum-coated chip bags

Manufacturing prioritizes locally available plastics (Vietnam-sourced LDPE/HDPE dominance) and tolerates mixed contaminants like sand or minor PET fragments[1]. Avoid PVC entirely due to toxicity risks[2].
