No, I don't recall saying that.
Roughly half, maybe just a little less than half of the 85 facilities in the United States are privately owned. About 44 of the 85, I believe, are publicly owned.
Oftentimes it's public. Whether it's owned by the local government or owned by a private company, it is a public–private partnership. The municipalities are the jurisdictions with the closest ties to the trash, and you need that trash to make a facility work.
There are private facilities under development in the United States today.
