Construction and Start-Up of the Biodigestion Plant for the Municipality of Xalapa, Veracruz, First Phase

Description

The purpose of this bid is the supply, installation and start-up of a biodigestion system for the treatment of municipal solid waste generated in the municipality of Xalapa, Veracruz. 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 must have the capacity to provide a biodigestion and biogas storage volume for a capacity of 12,000 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 improper materials), anaerobic biodigestion, aerobic stabilization of the digestate, storage and energy recovery of the biogas for self-consumption by the biodigestion plant, and export of the surplus.

The biodigestion process will consist of the following stages: MSW reception and discharge, simple mechanical re-treatment (recovery of materials and separation of unwanted waste), 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.

The Bidder shall carry out all the engineering works necessary for the adaptation of the design, manufacture, assembly, commissioning and operation of all the equipment and systems included in the Biodigestion Plant required by the Municipality of Xalapa.
