Objetivos

The specific objectives of UMBRELLA and METHAGRO are:

• UMBRELLA:

  • GHG mitigation in the process of wastewater treatment: 1.2 t CO₂e/d

  • Reduction of H₂S in biogas: up to 80%

  • Nitrogen treatment capacity: 70 kg/d

  • Reduction of effluent suspended solids: 95%

  • Reduction of BOD: 50%

  • Reduction of energy consumption >70% compared to conventional treatments

• METHAGRO:

  • Increase of the concentration of CH₄ in the biomethane > 95% compared to the concentration in the biogas of 50%

  • The emission into the atmosphere of 2,064 kg SO₂/y shall be avoided

  • The emission of 9,500 t CO₂/y into the atmosphere will be avoided due to the use of CBM generated in vehicles

  • Decrease of emission of particles per vehicle of 3,105 kg/year due to the conumption of CBM generated in the upgrading

  • Reduction of the risk of contamination of aquifers by use of 12,930 t/y of slurry 

  • Use 7,350 t/y of organic waste

  • Implement energy-efficient technologies (10% lowe energy conumption in anaerobic digesters, 80% lower in the upgrading process) with a heat recovery in the upgrading phase of 240 MWH/y

General objectives

The expected results from the use of biomethane as automotive fuel are:

• 80% minimum CO₂ emissions reduction in the Well-to-Wheel balance compared to currently marketed CNG.

• Decrease annual emission of particles up to 6.21 kg per vehicle. 

• Promote biomethane consumption for both light and heavy vehicles, and its widespread availability and commercialization. 

• Partial compliance with the Spanish Energy Saving and Efficiency plan and the Renewable Energy plan for 2011-2020, and the energy efficiency directives 2012/27/EU and the EU biofuel promotion goals.
