Abstract: Fresh waste residue _alpeorujo_ (1) coming from the olive oil press is subjected to a series of steps which will enable valuable by-products, which were previously residues, as this the waste residue (1) is dehydrated (4) by means of centrifugation. The solid fraction (6) that is obtained is firstly dried (9) to be separated later into pulp (12) and stone (13), while the liquid fraction (5) is centrifuged (18) in order to separate the solids (19) and to obtain crude alpechin (raw vegetable water) (20) which after subjecting it to centrifugation (21), biological treatment (25), alcohol fermentation (26) and filtration (27), is concentrated (32) using a multiple stage vacuum evaporator, such as a to produce a concentrate (34) with multiple applications, along with condensed water (35) which move to a column used to purify the volatile substances (36) in order to separate the alcohol (38) from the water (43), and finally proceed to purifying it using the respective treatment columns (39) and (45).
