Northstar Lime LLC in Crookston, Minnesota is one of 21 projects that will soon be open for public comment regarding its participation in the Fertilizer Production Expansion Program. Bryan Boll farms near Crookston and leads Northstar Lime. Boll says the technology is a win-win-win. “Instead of burning cornstalk bales, we’re able to turn that into biochar, capture that carbon, and put it back on the field to increase organic matter.” The Northstar Lime pellets are made from a byproduct at the nearby American Crystal Sugar plant. The pyrolizer used to create biochar will produce heat to dry the lime and produce a value-added product while capturing carbon that would otherwise be released into the atmosphere. The pyrolizer should be up and running sometime this spring.
