QAP, Engineering Reviews and EP3: Cellulosic Ethanol From Corn Kernel Fiber

With the release of the ASTM E3417-24 analytical method, ethanol producers can navigate the complex generation of Cellulosic (D3) RINs from Corn Kernel Fiber (CKF), with a recognized approach to quantify cellulosic content from corn. This method, certified by a Voluntary Consensus Standards Body (VCSB), enables ethanol producers to quantify the cellulosic content of corn and generate D3 RINs
from that cellulosic portion in-situ with corn starch.

Dry Mill ethanol producers wishing to generate D3 RINs or those recently registered with the EPA to generate D3 RINs from CKF must follow requirements specific to D3 RIN generations, in addition to those requirements for D6 RIN generation. To fully leverage this opportunity, ethanol producers may wish to be under an approved Quality Assurance Plan (QAP) due to the D3 RIN market demands for Q-RINs.
