A team led by Dr Theodor Eduard Suess in Austria adapted the process and scaled it to industrial size, after which it was commercialized by VÖEST and ÖAMG.

[2] In 1943 Durrer returned from Nazi Germany to Switzerland and was appointed to the board of von Roll AG, the country's largest steelmaker.

[1] Durrer teamed up with Heinrich Heilbrugge and ran a series of experiments which established the commercial viability of basic oxygen metallurgy.

[1] In the summer of 1948 von Roll AG and two Austrian state-owned companies, VÖEST and ÖAMG, agreed to commercialize the Durrer process.

[3] Their commercial converter furnaces were put into operation in November 1952 (VÖEST in Linz) and May 1953 (ÖAMG, Donawitz)[4] and temporarily became the leading edge of the world's steelmaking, causing a surge in steel-related research.
