Bulgaria opens industrial park in Sliven: a new hub for production, logistics and regional competition

Bulgaria has officially inaugurated Sliven Industrial Park, an infrastructure project worth approximately EUR 12.2 million. The project was implemented with support from European Union funding and is regarded as one of the largest infrastructure initiatives of the Municipality of Sliven.

According to SeeNews, the park was opened in April 2026, while the total value of the investment is estimated at EUR 12.2 million, or around USD 14.2 million. The project was supported by EU funds, including under Bulgaria’s Recovery and Resilience Plan.

Sliven Industrial Park covers approximately 2,684 decares, or about 667 acres. It is located on the territory of the former Burshen Airport near the city of Sliven. According to Bulgarian investment sources, the park is among the country’s major industrial development projects and is the third large-scale industrial park entered in the national register of industrial parks.

An important geographical clarification should be made: in official and media reports, Sliven is usually described as a city in south-eastern, rather than south-western, Bulgaria. This distinction is relevant for correctly positioning the park within the system of transport links connecting Bulgaria’s inland regions, the Port of Burgas, the Trakia motorway and the wider Black Sea area.

The project has a clear logistics dimension. The park includes a 2.5-kilometre runway, which could potentially be adapted for cargo airport operations, as well as an internal railway line to serve production, warehouse and logistics needs.

Structurally, the park is divided into 17 blocks across four zones: northern, south-eastern, south-western, and the “Airport and Motorway” zone. The largest of them — the “Airport and Motorway” zone — covers about 1,660 decares.

For the Municipality of Sliven, this project has not only local but also regional significance. It creates a prepared investment site for manufacturing, warehousing, logistics and technology companies. The official concept of the park provides for its operation as a Type A industrial park, meaning that it is not limited to a narrow sectoral specialisation. This makes it possible to attract a broad range of investors — from light industry to logistics operators and export-oriented manufacturers.

In a broader context, the opening of such a site demonstrates the growing competition among South-East European regions for industrial investment. Bulgaria is actively using European recovery and regional development instruments to create infrastructure that can accommodate investors quickly and reduce their initial entry costs.

Comment by the Institute of Danube Research

According to the IDR, the combination of industrial infrastructure, railway access, a potential cargo aviation component and proximity to key transport corridors gives Sliven a new role in the regional economy. For Ukraine, this is also an important signal: competition for investment in South-East Europe will increasingly be determined not only by tax conditions, but also by the quality of prepared infrastructure, the speed of connection to utility networks and the capacity of municipalities to work effectively with investors.

Sliven Industrial Park is an example of an infrastructure project that combines local economic development, European financing and logistics positioning. For the Danube–Black Sea region, such projects are shaping a new map of industrial competition, in which communities, ports, transport hubs and industrial sites increasingly function as elements of a single regional economic system.

Vitaliy Barvinenko, Director of the Institute of Danube Research, Doctor of Law, Professor:

“ The opening of the industrial park in Sliven is a representative example of how countries in the region are using European funding not only to restore infrastructure, but also to shape a new economic geography. This experience is important for Ukraine for two reasons. First, it demonstrates that industrial parks should be viewed not as isolated sites, but as part of a transport and logistics system. Second, it underlines the need for more active development of similar instruments in Ukraine’s border and port regions, particularly in the Danube region. ”
