Overview
BorsodChem is a Hungarian chemical raw-material manufacturer headquartered in Kazincbarcika, in northeastern Hungary. It operates as the European member of Wanhua Chemical Group, a partially state-owned Chinese chemical group, and is principally associated with polyurethane raw materials, polyvinyl chloride and chlor-alkali products. Its principal industrial complex is located in Kazincbarcika, with additional European production capacity in Ostrava in the Czech Republic and Kędzierzyn-Koźle in Poland. The company also maintains commercial and technical offices in several European countries and has operated a research and technical-support centre in Gödöllő since 2008. The company traces its origins to the decision taken at the end of 1949 to establish the Borsodi Vegyi Kombinát, or BVK. The site was selected because of its proximity to coal resources, the Sajó River, roads and railways. Construction between 1950 and 1955 created a large integrated industrial complex containing coal, coking, power and nitrogen-related chemical facilities. The plant was inaugurated on 10 December 1955, although construction problems delayed continuous production for several years. Its development helped transform the surrounding area and contributed to Kazincbarcika receiving city status in 1954. A major technological and commercial shift began in 1963, when the predecessor moved from coal-based synthesis gas toward natural-gas-based production and discontinued its coke-related operations. The business combined with Berente Chemical Works and began producing thermoplastic PVC under the Olefin I programme, together with chlorine and hydrochloric acid. Further investment added nitrogen, urea and additional PVC capacity. PVC plants commissioned in the late 1960s and early 1970s made the company an important participant in Hungary's plastics industry. During the 1970s and 1980s, it expanded into plastic processing, including compounding and PVC window products, while also developing phosgene-related capabilities that later supported polyurethane chemistry. BorsodChem was formally established on 1 August 1991 as the legal successor to BVK. It became one of Hungary's largest chemical companies and was admitted to both the Budapest Stock Exchange and the London Stock Exchange in 1996. The company acquired a 28.5 percent interest in Tiszai Vegyi Kombinát in 2000, later selling that holding to MOL. The same period also brought controversy around the acquisition of a 24.7 percent stake by the Irish-registered Milford Holdings and its subsequent sale to CIB, the Hungarian subsidiary of Banca Commerciale Italiana. Vienna Capital Partners was associated with the transaction, and the Hungarian prime minister called for an investigation. Permira acquired majority ownership in 2006 and the company was delisted the following year. Wanhua Industrial Group and Wanhua Chemical Group subsequently became the controlling owners, with management under the Wanhua group from 2011. In 2019, a successor of Wanhua Industrial Group transferred its BorsodChem shares into Wanhua Chemical Group, consolidating the company's place within the Chinese group's international polyurethane and chemical-materials platform. Recent development has focused on expanding upstream and supporting production at the Kazincbarcika and Berente-area complex. A brownfield aniline plant was announced in 2018, with reported investment of EUR 142.2 million and Hungarian state support of EUR 45 million; the plant was expected to create approximately 50 jobs. In 2019, BorsodChem contracted Casale SA for an additional nitric-acid plant. The associated development programme was inaugurated in July 2023 and was described as involving approximately EUR 400 million in new production units, including a concentrated nitric-acid facility with annual capacity of 90,000 tonnes. In 2021, the company also contracted Linde to supply nitrogen, oxygen and compressed air and to build a large air-separation plant…
History
BorsodChem developed from Borsodi Vegyi Kombinát, whose creation was decided at the end of 1949. The planned industrial complex used the area's coal resources, water from the Sajó, and road and rail connections. Construction from 1950 to 1955 included coal classification, coking, power generation, nitrogen chemistry and associated service plants. The complex was inaugurated on 10 December 1955 and became one of Hungary's largest industrial facilities, although technical and construction problems delayed continuous production. In 1963, the predecessor company shifted from coal-based synthesis gas to natural-gas-based production and ended its coke-based operations. It merged with Berente Chemical Works and entered the PVC industry through the Olefin I programme. The resulting chlorine, hydrochloric-acid and PVC operations formed the foundation of the company's later vinyl business. Nitrogen and urea capacity was expanded during the 1960s, while PVC II began operation in 1969. A plant capable of producing 150,000 tonnes of PVC annually was completed in 1971, followed by another PVC facility in 1974 using purchased ethylene from Tiszai Vegyi Kombinát. During the 1980s, the company extended its activities into plastic processing, including compounding, PVC windows and phosgene production. BorsodChem was legally established on 1 August 1991 as the successor to Borsodi Vegyi Kombinát. It became publicly traded in 1996 on both the Budapest and London stock exchanges. In 2000, it acquired 28.5 percent of Tiszai Vegyi Kombinát, later selling the stake to MOL. That year, the purchase and resale of a 24.7 percent stake involving Milford Holdings, CIB and Vienna Capital Partners prompted political scrutiny and a call for investigation by the Hungarian prime minister. Permira acquired majority ownership in 2006, and BorsodChem was removed from the stock market the next year. Wanhua Industrial Group and Wanhua Chemical Group later acquired control, and Wanhua-managed ownership became effective from 2011. In 2019, BorsodChem's shares held by a successor of Wanhua Industrial Group were injected into Wanhua Chemical Group's listed structure. Since 2008, BorsodChem has maintained an R&D and technical-support centre in Gödöllő. Its European manufacturing network includes the Hungarian Kazincbarcika site and capacities in Ostrava, Czech Republic, and Kędzierzyn-Koźle, Poland. More recent capital projects have included an aniline plant, an additional nitric-acid plant and a Linde air-separation facility. These projects support the company's integrated production of polyurethane raw materials, PVC, chlor-alkali products and specialty chemicals.
