• Producing 1 ton of yeast absorbs 3 tons of greenhouse gases for every 2 tons emitted
• The result was verified by ICC Animal Nutrition based on scientific studies and mathematical estimates

Science has already proven that Brazilian ethanol yeast is unique in terms of its efficiency in animal nutrition. The latest news – also proven by scientific studies and mathematical estimates – is that the production of ethanol from alcoholic fermentation by yeasts has a very significant positive environmental impact. With a negative balance of greenhouse gas emissions (mainly carbon dioxide – CO₂), this process stands out as a solution that contributes to combating current climate change.

“At every stage of the industrial process, we recognize that greenhouse gas (GHG) emissions are inevitable. We conducted a detailed assessment based on globally known and approved methodologies (GHG protocol) to map the emissions of these greenhouse gases and CO₂ (representing almost 75% of total emissions). This study revealed that in the growth of sugarcane we have a balance and absorption of approximately 17 tons of CO₂ for each hectare planted, establishing a negative and beneficial carbon cycle,” explains Fernando Braga, ICC’s global marketing manager.

With scientific validation and mathematical estimates, the company showed that during one crop year its operations and the volume of yeast produced emitted 4.4 million tons of carbon dioxide, but on the other hand, 7 million tons of CO₂ were absorbed. In other words, a negative balance of more than 2.6 million tons of these gases was generated. “In addition, each ton of yeast produced results in the emission of 2 tons of CO₂, but is capable of removing 3 tons of CO₂ from the environment. This virtuous cycle reinforces that the production of ethanol yeast is not only viable, but exemplarily sustainable and connected to the world we live in today,” Braga points out.

In a global scenario in which the transition to renewable energy sources is imperative, ethanol yeast has emerged as a highly sustainable technology. “Our efforts towards sustainability and carbon footprint continue to grow and now is the time to achieve certifications from global companies,” concludes the manager.
