53. Quantity of material for anaerobic digestion

Description

Estimates mass of materials going to anaerobic digestion.

Methodology

Sum of organic material going to anaerobic digestion. Data may come from demo managers, waste management companies or the Sector Circularity Assessment Method.

The information above is specific to Sevilla's evaluation plan. For general information on this indicator, please refer to its entry in the list of indicators. What follows below is what has been filled out by the city.

Rationale

Part of the actions planned by the city of Seville consists in testing the methane production capacity of the biowaste collected through a process of anaerobic codigestion with sewage sludge in a wastewater treatment plant (WWTP).

As part of this pilot, it is essential to know the quantity of biowaste introduced in the anaerobic codigestion plant, in order to optimize the process itself.

Comments

Key elements:
- Physical characterisation of the biowaste collected.
- Lab analysis of COD, BMP and others parameters to determine the capacity of methane production.
-Measuring of the methane production. Analysis of the gas produced (sulphide, methane, CO2, etc.)
