Hrastnik1860 has produced 100% carbon neutral glass bottles for French wine producer Château d’Esclans using hydrogen combustion.

The carbon neutral bottles contain Chateau d’Esclans’ 2023 Vintage Garrus wine.

With over 60% hydrogen fuel content used for glass melting, the direct carbon footprint of the melting process is reduced by more than 30% compared to standard procedures.

Hrastnik first revealed it had successfully produced premium glass bottles using hydrogen as a prime energy source last year.
