Montana Renewables, working together with Calumet Montana Refining, has set up new on‑site blending and shipping facilities to produce a fuel that is roughly half renewable and half traditional jet fuel. This blend meets the aviation industry standards ASTM D7566 and ASTM D1655, and can be used as a “drop‑in” replacement without changing existing aircraft or fueling infrastructure. https://www.coherentmarketinsights.com/news/montana-renewables-launched-sustainable-aviation-fuel-blend-1767
