Most benefits of biogas plants are environment-related, as they produce renewable energy for domestic and industrial use. This energy can be stored or injected into the electricity grid to reduce dependence on fossil-fuel energy, which can help reduce our carbon footprint.
In other words, biogas plants can help to fight climate change. As domestic and industrial users rely less on the energy produced with fossil fuels, greenhouse gas emissions become lower. At the same time, by gathering organic matter and controlling the fermentation process, fewer methane emissions get into the atmosphere for improved air quality.
Communities reach these results while managing food waste and preventing garbage from ending up in landfills. Recycling organic waste means fewer odors, a minimum risk for spreading diseases, and protected water bodies, among other things.
Another advantage of biogas plants is eliminating the need for synthetic fertilizers, as they get replaced by digestate. It recirculates a series of nutrients, such as phosphorus, which is essential for healthy crops.
Besides the positive effects on the environment, biogas plants contribute to building a circular economy, in which more industries can become sustainable and self-sufficient by using their waste to obtain energy or heat. As the number of facilities grows, new jobs are generated across multiple verticals, with a significant impact on the quality of life in numerous communities worldwide.
