Summary:•Assessment of the influence of thermal pretreatment on the anaerobic biodegradation of wheat straw.•Optimum severity factor at 200°C and 5min (3.6 severity factor).•Evaluation through BMP tests: 27% increase in methane productivity of steam exploded straw respect untreated straw.•Cutting (3–5cm) wheat straw showed to be better than milling (
