In California, dairy farmers are increasingly adopting vermifiltration systems, which use worms and microbes in biofilters to significantly reduce methane, nitrous oxide, and water pollution from livestock manure. This approach, developed by the Chilean company BioFiltro, is seen as a simple and cost-effective solution to environmental challenges, especially as regulations tighten. While promising, researchers emphasize the need for further study to determine the long-term effectiveness and trade-offs of these methods under real farm conditions. AI
