Using biochar in cement to reduce carbon accounting.

Global Cement Demand
• Main challenge facing the cement industry is to reduce CO 2 emissions while meeting global demand

CO 2 Emissions from Cement Production-Global
• Concrete responsible for 8% of global anthropogenic CO2 emissions

Conclusions and Look Ahead

• Carbon capture, use and storage needed to meet the 2045 neutrality goal in the cement sector
• Biochar replacements up to certain amounts acceptable impact on strength
• Durability and compatibility with chemical admixtures need to be assessed
• Implementation easier for certain applications
