Currently, the plant has ceased activity and the old buildings were demolished to make room for new enterprises.The majority of high school students attend either Liceul Teoretic Petru Maior or the 'Industrial Highschool,' where many are trained to later work in mechanics, electrical and IT.

Exceptional students progress onto university studies, generally in nearby Cluj-Napoca or Alba Iulia, the county capital.

Now this area is filled with more than 4 large, salty and very deep ponds which are projected to become an big natural park.

The center of the town and city hall are located at the base of a large hill, the 'Banța.'
