Hour-level humification of papermaking waste residue to produce honeycomb-like controlled-release fertilizer

Key Points

• Controlled-release fertilizer achieved through hour-level humification of papermaking waste residue, enhancing nutrient delivery.
• The honeycomb-like structure of the produced fertilizer allows for gradual nutrient release, improving efficiency in plant uptake.
• Papermaking waste residue was systematically transformed, using specific humification processes to yield agricultural benefits.
• This approach supports sustainable agricultural practices, highlighting the potential for waste materials to contribute to eco-friendly fertilization.
