文摘
- •
We propose a novel method for calculating a nutrient footprint.
- •
Combined indicator of the amount and use efficiency of virgin and recycled nutrients.
- •
Case calculation for oat flakes had a good nutrient use efficiency (NUE) overall.
- •
The hotspots in the case were in the waste treatment processes with low NUEs.
- •
Aim of the method is to improve the NUE of bio-based materials and energy chains.
