08:29 AM EDT, 03/25/2025 (MT Newswires) -- O-I Glass ( OI ) said Tuesday it successfully completed a trial at its Harlow, UK, facility, replacing natural gas with 100% biofuel in the glassmaking process.

The trial combined biofuel with cullet preheating and an oxy-fuel furnace, resulting in a significant drop in carbon emissions, the company said.

O-I added the test confirmed biofuel's potential for large-scale use, though its adoption will depend on fuel availability and cost.

Shares of the company were up 1.3% in recent Tuesday premarket activity.
