GREEN BAY, Wis. (WRN) — There’s a new, more environmentally friendly option for firefighters who need to put out dangerous fires.

It’s a new firefighting foam made out of soybeans and can be used to smother fires that can’t be put out with water.

Fox 11 Green Bay reports several northeast Wisconsin fire departments have been testing the foam, which does not contain PFAS or other forever chemicals. That is believed to be one of the primary sources of contamination in Wisconsin.

State lawmakers are pushing for a rapid roll out of the Soy Foam, with the state Senate approving a bill that would offer grants and training to fire departments looking to switch to the option.
