In recent years, the production of renewable energy has become one of the most important topics in the agricultural sector. Biogas production plants are an opportunity to produce fertilizers and recover energy from agricultural biomass and/or waste from agri-food products and agricultural sewage. Biogas is produced from these biomasses in digesters through a process of controlled anaerobic fermentation. Veneta Mineraria's iron-based powder products are effective desulphurising additives that capture the sulphur released from the biomass, reducing the formation of hydrogen sulphide and sulphuric acid; the latter has a particularly corrosive impact on the metal structures and covers of the digesters and can cause extensive damage. Correct cleaning of the system by means of sulphur recovery helps preserve the integrity of the systems and improve their efficiency.
