LCA applied to residual organic fertilizing materials - An overview of substitution methodological options and quantitative substitution rates

摘要

1. Different methodological approaches, which require different information 2. No consensus on the substitution methodological approach 3. Substitution based on the fertilizing potential in the most frequent 4. Substitution in an attributive perspective → avoided mineral fertilizer production 5. Consequential perspective → cast doubt on the effective avoided production.
