Sustainable Biogas Purification System in Landfills and Municipal Solid Waste Treatment Plants.

LIFE BIOGASNET has demonstrated a new cost-effective and environmental friendly technology for biogas desulfurization based on biological processes, being able to obtain a high quality biogas and final valuable by-products.

The project has been focused on the promotion of renewable energies production through the circular economy concept: reducing waste generation, reducing the carbon footprint of the desulfurization process, and producing secondary raw materials such as elemental sulphur and ammonium sulphate.

Project's technology demonstration

Two prototype plants installed in Spain and Greece

The project has developed a prototype to be constructed and operated in two different European facilities with different biogas sources in order to validate the technology and to demonstrate its robustness under different conditions.

First, the prototype was installed and operated in Cádiz (Spain) with two main equipments: a nitrification bioreactor, fed by landfill leachate, and an anoxic bioscrubber fed by the effluent from the nitrification bioreactor and the biogas from the landfill wells. The prototype was moved to a Municipal Solid Waste Management Plant in Athens (Greece), where it was operated to obtain information about the performance of the LIFE BIOGASNET technology in another different scenario.
