In a recent article in Global Cement Magazine, Beta Analytic marketing specialist Haley Gershon describes how carbon-14 testing can help cement plants reduce their greenhouse gas inventories by measuring their biogenic, carbon-neutral carbon dioxide emissions.
Biomass has a known amount of carbon-14. By measuring the carbon-14 content of a CO2 sample, the exact percentage of the gas that is biomass-derived can be determined. Carbon-14 testing is particularly useful for cement plants using alternative fuels, which are mixtures of biomass (e.g. paper, wood) and fossil inputs (e.g. plastics, petrochemical-derived surfactants). Examples of alternative fuels include refuse-derived fuels, municipal solid waste, sewage sludge and used tires.
Carbon-14 testing is done using standardized methods ASTM D6866 or EN 15440 (superseded by BS EN ISO 21644:2021). Results are reported as % biogenic carbon content or % biogenic CO2. If carbon-14 analysis indicates that a stack gas sample is 65% biogenic CO2, this means that 65% of the gas is derived from biomass and 35% is fossil-based.
