A study of organic loading rate (OLR) and effect of NaOH concentration on the pretreatment stage of corn husk (CH) was conducted by Face-Centered Central Composite Design (CCF) to improve the biogas production. Three levels of OLR at 25.0 g VS · L–1 · d–1 (OLR25), 35.0 g VS · L–1 · d–1 (OLR35), and 45.0 g VS · L–1 · d–1 (OLR45) we
