VALDES LOPEZ, Alejandro; LOPEZ BASTIDA, Eduardo Julio  e  RAMOS MIRANDA, Fernando Efrén. On the use of Gydema company's waste for the production of refined corn oil. Universidad y Sociedad [online]. 2022, vol.14, n.3, pp. 309-317.  Epub 30-Jun-2022. ISSN 2218-3620.

At present, vegetable oils are among the products most demanded by the Cuban population, which is why it is of great importance to analyze the potentials for their production in the national territory. Therefore, the objective of this work was to evaluate the viability of producing refined corn oil from the residual germ of the production process of the UEB Glucose Cienfuegos. Through a simulation in the software Aspen HYSYS, it was estimated that approximately 1022 L of refined oil / day can be obtained, generating 151,2 kg / day of soaps as a co-product. An average initial investment of $ 2,04 million is required to implement the technology and the most likely payback period is 4,8 years. The risk level of the investment is considered medium and in general it was identified that the current low production flow is the factor that most threatens the viability of the proposal. However, the implementation of the technological proposal can contribute to achieving greater food security in the territory and greater benefits in the company since it allows obtaining a product with great social demand from the recovery of a waste. In addition, the co-product obtained favors the diversification of the company's assortment and the productive linkage with other industries in the national territory.
