EPA updates guidance on corn kernel fiber-based cellulosic ethanol
September 29, 2022
| Meghan Sapp
In its guidance, EPA proposes three potential ways companies might satisfy registration requirements for corn fiber, including:
· Adoption of the DOE/NREL method,
· Demonstration of reasonable accuracy by returning comparable cellulose values to the NIST reference materials using a non-voluntary consensus standards body (non-VCSB) method, or
· Use of advanced analytical techniques; e.g. mass spectrometry (MS) and nuclear magnetic resonance spectroscopy (NMR), as identified by DOE/NREL in their analytical method and validation.
