Речь идет о производстве пробок для бутылок шампанского

Контекст:
... a thorough selection of the cork planks which are then submitted to a decontamination by its exclusive ABC-1 process, whose operating principle lies in a second boiling of the cork in an autoclave with the following advantages:

- Absence for an environment favorable for the development of microorganisms and moulds.

И что это за процесс ABC-1 process?

Заранее спасибо!
