Industrial gas company SIAD Slovakia, part of the SIAD Group, has launched a plant in Leopoldov that will recover and liquefy biogenic carbon dioxide released from the production of bioethanol – a renewable alternative to fossil fuels.
The plant, which cost €11m to build, is expected to produce 40,000 tonnes of biogenic food-grade CO2, an amount which could double in the second phase of the project. This reduces the carbon footprint of bioethanol production at the site by 35%, according to SIAD.
SIAD and its partners Enviral – a member of biofuel producer the Envien Group – and alcohol producer Slovenské liehovary a likérky will use technology developed by Tecno Project Industriale (TPI) to capture the biogenic CO2 from gas produced during the fermentation phase in bioethanol production, where corn starch is converted into ethyl alcohol through a biotechnological process.
“Thanks to this technology, we are able to capture and liquefy biogenic carbon dioxide, thus avoiding the extraction of fossil CO2 from underground sources,” said Robert Spisak, Envien Group Chairman of the Board. “It is captured directly from production at our plant and is not released freely into the air.”
