The chemical reactions and pathways resulting in the formation of terpenoids, independent of mevalonate. Isopentenyl diphosphate (IPP) is the fundamental unit in terpenoid biosynthesis, and in mevalonate-independent biosynthesis, it is produced from pyruvate and glyceraldehyde 3-phosphate via intermediates including 1-deoxy-D-xylulose 5-phosphate.
