From marine plastic to an experimental sail
TECHNICAL ANNEX
The technical annex documents six stages—recover, sort, transform, spin, build and validate—to turn marine plastic waste into an experimental nautical laminate. The process prioritises traceability, cleanliness, homogeneity, mechanical strength and end-of-life recyclability.

Validate
01 Recovery and material preparation
- Selective, geolocated collection
- Sorting into PET, PE and PP families
- Washing and contaminant removal
- Shredding and flake homogenisation
- Recovered batch traceability
02 From plastic to technical yarn
- Controlled drying
- Polymer extrusion and filtration
- Homogeneous recycled pellets
- Filament spinning and drawing
- Winding and testing title, tenacity and elongation
03 Sail construction and validation
- Panel design and fibre orientation
- Multilayer thermal lamination
- Cutting and reinforcement assembly
- Tensile, tear and fatigue tests
- Sea trial and result documentation
The sail is not the end of the process: it proves that the material works.
