The Privatization Agency is considering an offer from Solvay Sodi AD, the nation's only soda ash producer and majority owned by Belgium's Solvay SA, to buy three state-owned companies to reduce the country's debt to Spain. The offer is for privatization of a 77% stake in the Thermal Power Plant-Devnya, a 78% stake in the Geosol-Provadiya company and an 80% stake in the plant for the extraction of limestone in the village of Chernevo. Solvay Sodi has offered to pay 20% of the total price directly to the government, with the remaining 80% going to Spain as part of an agreement between the Bulgarian and Spanish governments to settle Minerlabank's debts to Spanish creditors
