Make outdoor furniture with beams

EXTRUSION
PP
LDPE
HDPE
PRODUCT

We extrude various types of plastic into sticks, then assemble them into furniture. For the chairs, use sticks with a hard mixture for the legs and a soft mixture for the seat.

Hard Mixture: LDPE, HDPE, PP, PS
Soft Mixture: LDPE, HDPE, EVA (flip flops)

  1. We use a blend of plastic typically found on beaches or in nature: approximately 40% LDPE, 20% HDPE, 20% PP, 10% shrunk EPS, and a small amount of shredded PET, aluminum-coated chip bags, and EVA, but no PVC. We allow for some quality reduction. Toan Nguyen developed the first extruders in Vietnam.

  2. Choose a furniture design, possibly replicating an existing wooden piece, and prepare the necessary components.

    Typically, straight beams suffice, but sticks can be bent for rounded elements.

  3. Assemble the parts, screwing them together as you would with wood, to complete your furniture.

  4. Efficient Processing of Various Plastics

    Our method allows for the processing of numerous types of plastic. We construct items such as outdoor shelves and tables. More about our process can be seen in this video:

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

Additional Resources

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].
