<P><B>Abstract</B></P> <P>This study examined the effect of co-ensiling of wheat straw and sugar beet leaves on the biochemical methane potential (BMP) by both lab-scale and pilot-scale co-ensiling. BMP was increased by co-ensiling, and the increase ranged from 19 to 34% after 9months of co-ensiling in lab-scale and from 18 to 32% after 6months of co-ensiling in pilot-scale. No effluent run-off was found through pilot-scale co-ensiling and there was a mass loss of only 0.1%. The study demonstrates that co-ensiling of straw and green biomass has potential as biological pretreatment and for avoiding effluent run-off from pure beet leave silage.</P> <P><B>Highlights</B></P> <P> <UL> <LI> The effects of co-ensiling were studied in lab-scale and pilot-scale experiments. </LI> <LI> Co-ensiling of straw and beet leaves increased the specific methane yield 18–34%. </LI> <LI> No effluent run-off was observed from a straw-beet leaves mixture with 28.9% DM. </LI> <LI> Co-ensiling shows promise as a biological pretreatment method for straw for biogas. </LI> </UL> </P>
