The cashew tree, Anacardium occidentale L., belongs to the family Anacardiaceae and originates in the semi-arid region of northeastern Brazil, is one of the species that presents great importance as a source of wealth and work opportunities in a region that faces drought as a secular problem. Its economic and social potential results in the occupation of labor during the off-season and alternatives offered by its products and derivatives. However, the cashew production chain has been experiencing difficulties due to bottlenecks in climatic factors, production and industrialization. In this context, we can enumerate the main obstacles: low rainfall, the advanced age of cashew trees, production mediated by middlemen and, not least, industrial thermomechanical processes that compromise the final products of cashew nuts. The high cracking and staining index of cashew nut (CN), together with the polymerization of cashew nut shell liquid (CNSL), results in the loss of the quality of these products, and consequently, the decrease in the position of the international market to other countries like Vietnam and India. In addition to these factors, the industrial technology adopted is responsible for generating a strong environmental impact due to the toxicity of its effluents and poor utilization of the residues of the cashew peduncle. In view of the above, the present work aims to present the model of implementation of a chain of biorrefinaries energetically interconnected by a photovoltaic system, making use of technologies that add value to the products of the cashew in a sustainable way and promote the social development through the insertion of the small producer at all stages of the production chain processes. The chain will consist of four biorefineries in the mini-factories mold, which will carry out the activities of early dwarf cashew, silage system for animal feed, production of clarified juices, processing of cashew nut by freezing and ultrasonic system and extraction of cold LCC. The installation will be planned in the experimental field of Embrapa in the Pacajus polo and will generate a process patent.
