Abstract

The present invention is located in the field of sustainable agriculture, referring to two processes of renewable origin for the production of fertilizer from by-products of animal origin, with two innovative raw materials:

whole fish and/or fish waste and/or fish waste of marine or freshwater origin and/or fish waste containing by-catch fauna, and the pre-treatment developed in the process makes it possible to process any fish species to obtain fish concentrate (CPX), an intermediate product in the subsequent obtaining of fertilizer compositions and/or for use as an ingredient in compositions intended for animal feed.Poultry viscera waste. The development aims at making use of raw materials and by-products of poultry viscera to obtain fertilizers with innovative characteristics. The synergy promoted by the stages of the developed process, combined with the qualities and characteristics of the chosen raw material, promoted the development of products with important levels of free natural amino acids, total organic carbon and organic matter.
