The objective of the present investigation was to use solid wastes (peel and seed) from the industrialization of camu-camu as a source of phenolic compounds, the variables considered for extraction of phenolic compounds were: the raw material / solvent ratio, the temperature and the extraction time. In relation to the solvent, a 50% ethanol solution was used, which was constant all the time. In the production of atomized camu- camu, 42.2% of solid waste was generated including the peel and the seed compared to the whole fruit, which, when dried and ground, had a humidity of 3.1% and a particle size of 56.2% ≤ 0.42 mm. A factorial design was used for the screening with an array of 23 to identify those variables that significantly affect the extraction yield of the phenolic compounds. The variables used for the content of total phenolic compounds expressed in mg of equivalent gallic acid (EGA) / 100g dry matter were optimized through a rotatable central composite design with 5 replications in the central point. The conditions to maximize the phenolic compound content were: 55 ° C for temperature and 1/42 for the raw material / solvent ratio together with the extraction time of 30 minutes, obtaining a value of 5939.1 mg of equivalent gallic acid (EGA) / 100g of dry matter. The identification of phenolic compounds by the high performance liquid chromatography (HPLC) technique, at 280 nm, revealed 22 main peaks grouped into: ellagic acid derivatives, flavan -3- ol derivatives (or flavanols derivatives) and flavanone derivatives, in addition ellagic acid was identified the way it is. At 360 nm, rutin was identified. In conclusion, the solid waste from the industrialization of camu-camu is an important phenolic compound source, making it a good alternative to use, avoiding a sanitary landfill destination, achieving its valorization, and a solution within the environmental integral management of wastes
