Binz grew up in Mesenich and Moritzheim (Hunsrück). She graduated from high school in 2003 and moved to Mainz, where she studied political science, history and philosophy at the Johannes Gutenberg University. In the 2005-2006 election period, she was chairperson of the AStA at Mainz University. She then moved from the level of local student politics to the national level and was a board member of the national student association "freier zusammenschluss von student*innenschaften". The AStA of the University of Mainz was able to win her back as a speaker for political education in 2009.
Since 2007, Binz has been a member of the district executive of Bündnis 90/Die Grünen Mainz. She became active in local politics in the 2009 local elections in Rhineland-Palatinate, in which she won a seat on the Mainz city council. She was also elected as a successor for one of three seats for the Greens on the local council of the Hartenberg-Münchfeld district, and took up the mandate on 8 August 2011. She left this body on 30 November 2013 due to a move to Mainz-Finthen.
