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.
