In this paper, the construction method outlined criteria identifys for the agro-industrial production model toward dual-closed ecological direction for coconut jelly processing facility. Set up criteria determines the impacts of production technology, the efficiency of using energy and natural resources, sustainable livelihoods, and the replicability of the model that will affect on the sustainability of the model. The research methodology was based on the results of surveys, investigation, and assessment of current model, and identifying a scientific basis for the set up criteria. Based on that, set up criteria was propose and application for a coconut jelly processing facility for Nguyen Thanh Trung household in Nhon Thanh commnune, Ben Tre city, Ben Tre province and recommend the solution for completed model based on eco-technique and closed matter & energy line. The results of the model meet all the requirements of the set up criteria. The quality of water supply meets the standards for coconut jelly processing. Treated wastewater by aquatic plants system meets the standard for wastewater discharges into the water resource. Water comsumption was saved and reduced the greenhouse gas emissions from burning wood for coconut jelly processing. The production costs were saved, resulting increasing income for household. This is pilot the perfected model to expand to other facilities
