This study aims to propose an industrial-agricultural symbiosis model that applies the closed sloop eco-technical solutions for cassava starch production towards sustainable development. This study applies the AHP method to analyze nine alternatives and determines the best one based on 17 specific criteria for the typical cassava starch production plant in Tay Ninh province. The chosen model has 12 losed sloop solutions and can save about 40% groundwater, hundreds of cubic metre of water for irrigation in agriculture (to meet hundreds of hectares of crops), limit the lack of water in the dry season and water regulation from the Dau Tieng lake and reduce from 19-73% emissions from traffic,... Wastewater after Biogas is diluted in proportion for cassava is 28l wastewater/49l of clean water and the rubber tree is 8,5l of wastewater/7l of clean water and sugar-apple is 20l wastewater/20l of clean water wasto spray as a natural leaf fertilizer, limiting the use of NPK chemical fertilizers. Some indicators of wastewater after treatment show that it is suitable for use as fertilizer but suitable for nutrient development in the soil and increase nitrogen for plant development, reducing the cost of using stimulating fertilizers. In addition, production wastewater with high cyanide levels is also considered to dilute according to certain proportions as natural insecticidal drugs. These results show that industrial-agricultural symbiosis model bring great enviromental benifits for cassava starch industry and can be replicated in the future.
