and storage conditions (silos). The expected percentage nutritional losses for dried grain 4-6%, aerated grain 6-9% and Myco CURB ES liquid treated 0.4-0.5%, were calculated using an algorithm, where certain conditions of the grain and storage data from different studies were modelled, and nutritional losses are calculated and represented.
Results and Discussion The average electrical energy consumed, diesel fuel usage, nutritional losses and preservative addition, were converted to kg CO2
-eq per
ton of grain, using relevant models from the Ecoinvent database (v3.5) and Agri-footprint 5.0. The “carbon footprint” for Myco CURB ES liquid was calculated in collaboration with DOW using the IPCC 2013 method for global warming potential (IPCC 2013 GWP 100a). The result being that the carbon footprint of 1 kg of Myco CURB ES liquid is 2.3 kg of CO2
storage methods, as represented by the kg CO2 are represented in Figure 1.

Conclusion The results from this study show that drying and aerated grain has the highest climate change impact/carbon footprint compared to Myco

CURB ES liquid treated grain. The addition of a mould inhibitor, a preservative, based on propionic acid and a synergistic combination of other organic acids, their salts and surfactants enabled a reduction of approximately 2 to 3 times the carbon footprint in kg CO2
-eq/ton grain stored compared to aeration and drying methods,
respectively. Myco CURB ES liquid used for raw material preservation
contributes to environmental sustainability, mitigating the negative effects towards climate change.
