AI-assisted summary
Description from the seller
The clock "Don’t waste time", is a metaphor of the passage of time, which is running out, to act on climate change.
Its biodegradable material and the hands that mark an approximate time compel us to act on the planet. THIS IS A WAKE-UP CALL!
The material of the clocks is PLA, a plant-origin biopolymer derived from potato, corn, and cassava (depending on the supplier); this material is 100% biodegradable.
Specifically, PLA is a thermoplastic polymer produced by the fermentation of a carbohydrate source such as corn starch, potato, or cassava. In this case, the natural product is milled to separate the corn starch, mixing it with acidic or lactic monomers. With this mixture, the starch breaks down into dextrose (D-glucose) or corn sugar. Finally, the fermentation of glucose produces L-lactic acid, the building block of PLA. This material is considered a non-Newtonian pseudoplastic fluid, which means its viscosity (resistance to flow) will change depending on the stress applied. Specifically, PLA is a shear-thinning material, meaning its viscosity decreases with applied stress.
Some of the colors of the materials used to manufacture these watches are custom-made.
