The Whanganui Resource Recovery Centre was closed for a few hours on Saturday after a car ran into the wall in front of the plastic recycling bins.
"We were closed from around 10.30am until 1pm while we ascertained that no-one was injured and the damage was assessed," centre manager Dale Cobb said.
"The driver had a minor collision with another car and then I think he panicked and put his foot on the accelerator instead of the brake."
Cobb said emergency services were called to assess the drivers and the centre was closed as a precaution to ensure public safety.
"Saturday is a very busy day for us and we thought it was better for everyone's safety if we closed until it was sorted out.
