Implication

Demonstrates enhanced nutrient recovery in digestate using a 12% biodried product recycling ratio, implying improved environmental management.

Key Points

The research aims to optimize the recycling ratio of biodried product to enhance digestate valorization and address environmental challenges in food waste management.
Tested six biodried product treatments in 60 L bioreactors
Measured drying kinetics, product properties, and environmental-economic trade-offs
Evaluated nutrient content and energy recovery at varying recycling ratios
12% biodried product achieved peak temperature integral of 514.13 °C·d and optimal biodrying index of 3.67
Total nutrients reached 4.19%, meeting NY 525-2021 standards
Recycling reduced global warming potential by 27.3% and eliminated groundwater contamination risks
Achieved highest net present value (NPV) of USD 716,725 for the RDF pathway
