Applying circular economy principles to waste can help reduce agriculture’s dependence on chemical fertilisers.
Sludge from wastewater treatment plants, which is rich in carbon and nutrients, is already used as a bio-based fertiliser. However, treatment is required to remove pollutants such as heavy metals and microplastics.
This project seeks to develop a high-performance fertiliser by combining treated sludge with other waste materials. The mixture will be optimised through testing to enhance soil health and provide a safer alternative to chemical fertilisers. Laboratory and pilot studies will identify effective waste combinations, address variability, and establish cost-efficient methods.
An integrated waste management system will coordinate different waste streams into a zero-waste process, with pilot data confirming the sustainability and scalability of the approach.
