Abstract Assessing Availability and Environmental Impacts of Lignocellulosic Feedstock Supply - Case Study for a Catchment in England

Short introductive summary: 
Lignocellulosic feedstocks, including residual biomass ( maize stover and wheat straw) and dedicated energy crops(miscanthus and willow), are expected to have better performance in terms of climate change mitigation impacts compared with first generation biomass. Uncertainty remains in their potential availability and greenhouse gas emission (GHG) during the crop production. Our objective was to assess the relative availability of wheat straw and Miscanthus in England and to optimize land use to reduce environmental impacts associated with their supply. Using soil and climate variables for a catchment in East England biomass yields were simulated with validated process-based models, soil nitrogen emissions were estimated using DNDC model, and a ‘Field to upstream factory gate’ Life Cycle Assessment was conducted to estimate management-related GHG emissions. Results show that feedstock supply from wheat straw can be beneficially supplemented with LCB from willow or Miscanthus grown on marginal soils. Low input LCB crops are most likely to reduce nitrate leaching and GHG emissions, and additionally, increase SOC and improve soil quality.
