AUSTIN, TEXAS - Blue Sage Capital ("Blue Sage") is pleased to announce the formation of Blue Castle Waste Solutions ("Blue Castle"), a regional solid waste and recycling platform in the Midwest and Plains. Blue Castle was established through the concurrent partnering with founder-owned waste-collection businesses serving communities across Minnesota and Iowa.
