Sustainable, profitable and environmental friendly biogas purification system

LIFE BIOGASNET project demonstrates a cost-efficient and low-carbon footprint technology for biogas upgrading in order to boost the use of biogas as a sustainable energy source and reduce the carbon footprint of the energy cycle promoting the circular economy concept.

The project promotes an innovative technology for biogas desulphurisation coupling a nitrification bioreactor with either an anoxic gas-phase biotrickling filter or an anoxic bioscrubber.

The technology developed will present potential environmental advantages compared to current practices as it can reduce the environmental footprint up to 55% by reducing the carbon dioxide emission and the waste generation and allowing to obtain a secondary raw material suitable to be valorised.

Start Date: September 2019 – End date: March 2023

Promoting the use of biogas as a sustainable energy source


To demonstrate the feasibility and to promote the implementation of a new and versatile technology for biogas desulphurisation: 

Coupling a nitrification bioreactor and either an anoxic gas-phase biotrickling filter or an anoxic bioscrubber.

To promote a sustainable, low-carbon and technologically-advanced economy: 

The advanced biological process involves a reduction in the carbon footprint in comparison to traditional technologies.

To quantify the economic impact of the technology: 

In terms of reagents consumption savings and energy production and to compare the new technology benefits against currently applied technologies.

To promote resource efficient and competitive technologies: 

Bioprocesses are reliable, robust and low-carbon compared to physical-chemical techniques.

To obtain an energy-rich biogas stream with H2S concentrations:

Below the lower limit recommended by the combined head and power (CHP) plants manufacturers.

To reduce waste generation:

The project contributes to reduce leachate production in landfills by the use of ammonia-rich leachate from landfills as nitrite/nitrate source for the autotrophic desulphurisation.

To promote the implementation of environmental policies:

The project minimises the environmental impact of biogas emissions and/or combustion in flares.

To produce secondary raw materials:

The project allows the production of valuable by-products obtained from waste resources and the desulfurisation process.
