Sermonde (Aterro Sanitário) - 4.5 MW Biomass Power Plant in Portugal

Sermonde (Aterro Sanitário) is a biomass power plant located in Portugal, with a capacity of 4.5 MW. The facility uses waste as its primary fuel, aligning with Portugal's strategy to diversify renewable energy sources and manage waste sustainably. As a small-scale biomass plant, it plays a role in the local energy grid. The plant operates under Portugal's national regulations, which transpose the EU Industrial Emissions Directive (2010/75/EU). This framework sets emission limits for pollutants such as SOx, NOx, and particulate matter, and requires the use of Best Available Techniques (BAT) for waste-to-energy facilities. The plant's capacity is modest compared to larger biomass or thermal plants, but it represents a niche in the sector. By converting waste into electricity, the plant reduces landfill volumes and provides a local source of renewable energy. Its location in Portugal benefits from the country's growing focus on renewable energy, which includes biomass, wind, and solar. The facility supports regional waste management goals and contributes to the circular economy.

The plant's use of waste as fuel reduces methane emissions from landfills and provides a renewable energy source. However, biomass combustion can emit CO2, SOx, and NOx, though modern plants employ emission controls. Proximity to populated areas may raise air quality concerns, but Portugal's adherence to EU emission standards mitigates risks. The small capacity limits overall environmental impact.
