Don't waste time clock

Don't waste time clock its a call to action against the climate change

The material of the clocks is PLA, a biomaterial of vegetable origin derived from potato, corn, cassava (depending on the supplier) this material is 100% biodegradable. Specifically, PLA is a thermoplastic polymer that is produced by fermentation of a carbohydrate source such as corn, potato or cassava starch. In this case, the natural product is ground to separate the starch from the corn, mixing it with acid or lactic monomers. With this mixture, the starch is broken down into dextrose (D-glucose) or corn sugar. Finally, glucose fermentation produces L-lactic acid, the building block of PLA. This material is considered a non-Newtonian pseudoplastic fluid, meaning that its viscosity (resistance to flow) will change depending on the stress to which it is subjected. Specifically, PLA is a thin shear material, which means that the viscosity decreases with applied stress.
