Geosan Ltd. is a 100% hungarian owned private company. At the time of its foundation in 1996 the company operated based on the work of the Engineering Office, which was followed by the launch of the biotechnological branch-establishment.

The duties of the Engineering Office include environmental services, engineering-expertising tasks, and for the last few years also takes on assignments for experimental- and development-work from the areas of waste-disposal and hazardous-waste handling.

The biotechnological sub-division works on the industrial-size expending of the use of microbiology, specifically for agricultural and environmental-protection purposes.
