It's a Copernicia prunifera or AKA carnauba palms. That's the palm leaves carnauba wax is made from.
Carnauba, also called Brazil wax and palm wax, is a wax of the leaves of the palm Copernicia prunifera, a plant native to the northeastern Brazilian states of Piauí, Ceará, and Rio Grande do Norte.
It is known as "queen of waxes" and in its pure state, usually comes in the form of hard yellow-brown flakes.
It is obtained from the leaves of the carnauba palm by collecting and drying them, beating them to loosen the wax, then refining and bleaching the wax.
July to February is harvest season, the collection of the green leaves of carnauba palms are made by the natives that use a long stick with a cutting knife on the tip.
The carnauba leaves are spread over the ground and dried up in order for the powder to be removed by the ancient procedure of beating the leaves.
After that, the powder obtained from the beaten process is melted and squeezed in a wooden claw.
This primitive process is done by exporters that extract the powder with solvent extractor equipment.
Then, the cooling is made on flat tanks where the product is broken into "lumps" with colors that ranges from light yellow to dark brown.
This is the crude wax, ready for the manufacturing process at the exporters plant.
