The purpose of this bid is the supply, installation and start-up of a biodigestion system for the treatment of solid urban waste generated in the municipality of Xalapa, Veracruz. It must include the provision of a generator that will allow the conversion of the biogas generated into electrical energy, from the energy recovery by means of the aforementioned generator. The Biodigestion Plant will treat the Recovered Organic Waste (ROR) from the MSW of the municipality of Xalapa. It is expected to meet a demand of about 50% of the solid waste produced in the municipality of Xalapa.

 It should have the capacity to dispose of a biodigestion and biogas storage volume for a capacity of 21,900 t/year of ROR, as well as a mechanical pretreatment for a capacity of 73,000 t/year of MSW.

The biodigestion process will consist of the following stages: MSW reception and discharge, simple mechanical pretreatment (recovery of materials and separation of unwanted materials), anaerobic biodigestion, aerobic stabilization of the digestate, storage and energy recovery of the biogas for self-consumption of the Biodigestion Plant and export of the surplus.
