Material Transformation of Sewage Sludge into a Fertilizer with Increased Phosphorus Content

Description

Development and pilot testing of a processing line converting sewage sludge into phosphorus-rich biochar fertilizer using pyrolysis.

Sector

A1.6Support activities to agriculture and post-harvest crop activities

Needs/ Problem statement

Current sewage sludge management faces challenges in nutrient recovery and safe disposal. There is a need for technologies that transform sludge into valuable fertilizers while reducing environmental risks and enabling energy recovery.

Objective

To design and validate a processing line that converts sewage sludge into phosphorus-rich biochar fertilizer through pyrolysis, improving nutrient recovery and enabling energy utilization.
