Summary
This 2025 study describes the development of biochar-based fertiliser products through recovery of ammonium ions and subsequent design optimisation. The work represents an application-focused investigation into valorising biochar as a carrier or substrate for recovered nutrients, which may offer pathways for nutrient recovery from waste streams. The specific optimisation outcomes and agronomic performance data are not evident from the available metadata.
UK applicability
Biochar-based fertilisers align with UK policy interest in circular nutrient recovery and reducing synthetic fertiliser dependence. Applicability to field conditions would depend on subsequent agronomic trials and cost-benefit analysis in temperate systems.
Key measures
Ammonium ion recovery efficiency and biochar fertiliser composition parameters; optimisation design metrics (specific measures not stated in available metadata)
Outcomes reported
The study reports on the development and optimisation of biochar-based fertiliser formulations that incorporate recovered ammonium ions. As suggested by the title, the research focuses on design optimisation of such biochar fertilisers.
