Fossil and biogenic CO2 from waste incineration based on a yearlong radiocarbon study

► Yearlong radiocarbon study on the share of biogenic CO2 from waste incineration. ► Direct approach combining temporal integrating gas sampling and 14CO2 analysis by AMS. ► Significant differences between incinerators with 43% and 54%Fos C. ► No annual cycle of fossil CO2 for all, except one, of the included incinerators.
