Diam open new €30m factory in Southern France

Cork Closure manufacturer Diam Bouchage has opened a new €30 million factory in France’s Languedoc-Roussillon region. The 2000 square metre cork purification unit is located on the 5-hectare site in Vallespir that houses the company’s head office.

The new plant will enable Diam to increase its annual production capacity from the current level of 700m closures to a 2 billion. France is Diam’s main market, accounting for 30% of total sales worth €102m.

The purification element is a central aspect of Diam’s production process, which sees cork dust filtered for impurities before CO2 is used to extract negative sensory compounds such as TCA. The grains are then moulded, glued and satin-finished to create a range of closures.
