APROXAR was founded at the end of 1996 by engineer Guillermo Fernández Long to offer working solutions and answers to detected needs in the Oils and Fats Industry.

In 2001, external resources in Control Architecture and Industrial Systems Programming and Civil Engineering were incorporated to the company to respond to growing market needs. By 2004, specialists in the processing of animal fats by-products were hired to enhace the Process Engineering area.

These hires were also experienced in people management. By the second half of 2005, a new hire, expert in Process Engineering, joins the team to contrinute with his know-how of information administration.

By mid-June 2006, we started developing our own Quality Management System by hiring required staff for its implementation. we hired staff for purchase administration as well.

In 2007, we hired advanced engineering students in order to train future professionals specialized in the Industry.

In this way, our experience has allowed us to work globally, managing projects in North, South and Central America, Europe and Asia, either for national or international companies with or without subsidiaries in Argentina.
