Cellulosic Content of Various Feedstocks Spreadsheet – for the 2014 docket update

Air and Radiation Docket EPA-HQ-OAR-2012-0401

1-Jul-14

This spreadsheet shows the calculations used to adjust cellulosic 

content of different feedstocks starting with the numbers reported in 

the literature and ending with the values used by EPA. These adjustments 

are described in more detail in the memo to the docket ("Cellulosic Content of 

Various Feedstocks -2014 Update"). This is an update to the spreadsheet 

"Cellulosic Content of Various Feedstocks Spreadsheet - for the 

docket.xlsx" on Air and Radiation Docket EPA-HQ-OAR-2012-0401.

*When acid-detergent lignin was reported, we followed the approach described in Lee et

--For grasses, we multiplied the ADL number by 3 (total lignin is 2-4 times higher than ADL 

lignin for grasses)
