THE PROJECT

Sustainable, profitable and environmental friendly biogas purification system

LIFE BIOGASNET project has demonstrated 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 has promoted 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 presents potential environmental advantages compared to current practices as it can reduce the environmental footprint 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 2024

Promoting the use of biogas as a sustainable energy source

Objectives

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.
