The Viro sugar factory, commonly referred to as just Viro, is a sugar refinery based in Virovitica, Croatia.
The refinery was originally built in 1980 and had the daily refining capacity of 4,000 tons of sugar beet.[1] Established as an independent company, it was briefly part of the PIK Virovitica agricultural company between 1984 and 1991.[1] In the 1990s the refinery experienced a steady decline in revenue and income which resulted in it being bought and re-bought several times in the late 1990s, before eventually being acquired by the Dutch company Cosun and shortly after that filing for bankruptcy in 1999, with debts totaling some 575 million HRK.[1] After a period of internal restructuring the refinery's property was sold to two Croatian-based companies for 110 million HRK in 2002, after which the company was re-established as a limited liability company in September 2002.[1] The company's shares were listed on the Zagreb Stock Exchange in April 2006.[2]
