Effective management of crop straw is crucial for sustainable food production, renewable energy transition and climate change mitigation. However, accurately estimating reasonable removal rates to enhance grain yield and transition to bioenergy remains challenging. Through nationwide systematic surveys and meta-analysis, reasonable straw removal rates of 45 % for rice, 19 % for wheat, and 42 % for maize were identified in China. The potential bioenergy production derived from these reasonably removed straws ranges from 23 to 100 Mtce in 2022. The combined adjustment of straw utilization and fo...
