摘要

The production of citrus fruit in Spain generates more than 0.5 million tons of waste. This is mainly due to rejects when packing fresh fruit and the waste generated by processing industries. An important challenge for the citrus sector is the use ofthis waste to unlock its economic value and eliminate the environmental problems that it generates. The Instituto Universitario de Ingenieria de Alimentos para el Desarrollo (Iu-IAD) at the Universitat Politecnica de Valencia (UPV) has developed a systemfor transforming citrus waste into bioethanol and into high value-added products such as essential oils. The purpose of this study was to find the most appropriate sites to implement a bioethanol industry from citrus waste. A spreadsheet has been created to calculate the bioethanol mass flow from oranges, tangerines, lemons, and limes and grapefruits flow waste. Total waste of the main citrus producers was estimated as the sum of the rejects when packing fresh fruits and the waste generated by processing industries. Total waste value (oranges, tangerines, lemons and, limes and grapefruits) was multiplied by the ratio between mass flow and citrus waste flow in order to calculate the bioethanol production in different countries. The results suggest thatBrazil, USA, Mexico, China, India and Italy would be the most appropriate countries to implement a bioethanol industry from citrus waste.
