Adding value to Ash and Digestate: Developing a suite of novel land conditioners and plant fertilizers from the waste streams of biomass energy generation

Lancaster University, Stopford Energy & Environment, the James Hutton Institute and Aqua Enviro

The overarching aim of this project is to identify and examine novel nutrient-recycling pathways and retention mechanisms to maximise soil sustainability and crop productivity. For this purpose, bioenergy generation by-products (anaerobic digestate and biomass ash) will be combined and their suitability as alternatives to the finite mined-mineral P-and synthesised N-fertilisers will be assessed. As opposed to conventional fertiliser usage, this management will potentially conserve valuable resources while maintaining and/or boosting ecosystem environmental services
