Abstract: The present invention is located in the field of industrial biotechnology and sustainable agriculture, referring to a process of renewable origin for the production of fertilizer from by-products of animal origin, with an innovative raw material, animal blood in natura. The invention aims at the use of raw materials such as animal blood, both in natura form and in the form of blood meal, also considering a synergistic mixture of blood meal with in natura blood, to obtain fertilizers with innovative characteristics. The synergy promoted by the stages of the developed process, combined with the qualities of the selected raw materials, promoted the development of products with high levels of free natural amino acids, total organic carbon and organic matter. The developed fertilizer product can be applied in liquid form, as a liquid fertilizer, both in soil and in foliar form, as well as in solid form, after the introduction of a drying step at the end of processing.

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.
