LCA applied to residual organic fertilizing materials - An overview of emission inventory data at the spreading operation

摘要

1. N_20, NH_3, N0_3~-, PO_4~3- emissions more often considered than NO_X, N_2, C, trace metal elements in the case studies 2. A heavy impact of the inventory emissions on results → recommendation to pay particular attention to the inventory emissions 3. Need to close the N balance, essential in LCI 4. Site-specific emissions (NO_3_- NH_3, N_2O) → need for site measures or models 5. If the balance is not robust or if use of literature values → recommendation to perform a sensitivity analysis 6. Recommendations valid for organic products + mineral fertilizers (more difficult for the substituted system because of less data).
