The Biological Treatment of Gaseous Pollutants and Odours Group (BIOGAP) is now participating in the LIFE BIOGASNET project, whose aim is to develop a sustainable, biogas purification system in waste recycling centres and treatment plants for solid household waste.
The aim of the project is to demonstrate the viability of a low-cost, low-carbon footprint system for biogas conditioning, to promote the use of this fuel as a source of sustainable energy. The objective is also to reduce the carbon footprint in the energy cycle and promote the circular bioeconomy.


A prototype will be constructed that combines biogas desulfurisation with a system for treating waste effluent containing ammonia. Both techniques are based on biological processes developed by the BIOGAP Research Group, in collaboration with other university research groups. In this way, a double environmental objective is met, with the added value of producing by-product that are suitable for marketing in the fertiliser industry (elemental sulfur and/or ammonium sulfate). The prototype will be tested in two biogas production facilities of different characteristics to check its versatility.
The project is coordinated by the BIOGAP Research Group (that belongs to the TECNIO SSR-UPC centre). Other participants are two universities (the University of Cádiz and the National Technical University of Athens), two companies (Bioreciclaje de Cádiz, SA, and AERIS Tenologías Ambientales, SL) and Eurecat.
The project will take three years and a half. The total budget is 2.1 million euros, 55% of which has been funded by the LIFE Programme of the European Union.

- Microalgae-based wastewater treatment systems have demonstrated the ability to recover nutrients from wastewater and produce valuable biomass for agricultural applications while also recovering energy through the anaerobic digestion of residual biomass. In the Cyan2Bio project, in which the Group of Environmental Engineering and Microbiology (GEMMA) of the Universitat Politècnica de Catalunya - BarcelonaTech (UPC) is participating, an additional step will be taken in the valorisation of microalgae biomass to obtain biopolymers suitable for transformation into bioplastics alongside pigments, thereby replacing fossil-based materials.

These alternative proteins aim to provide a sustainable ingredient to meet the growing global demand for protein, applicable in the development of food and feed.
- The European project LIFE Biogasnet, coordinated by the Biological Treatment of Gaseous Contaminants and Odours Group (BIOGAP) at the Universitat Politècnica de Catalunya - BarcelonaTech (UPC), has validated a new biogas purification technology that improves the quality of this resource, produced in urban solid waste treatment plants and wastewater treatment facilities, while reducing the carbon footprint, thus promoting the concept of a circular economy. The new solution is based on efficient, low-cost biological technologies, combining a biotrickling filter with a nitrification bioreactor.
