Summary
This 2025 study by Tang and Rotter in Wasser und Abfall investigates collection and processing systems for human excreta at regional scale in Germany, with a view to producing recycling-based fertilisers. The work addresses both the technical and logistical challenges of closing nutrient loops through human waste recovery. As suggested by the journal and title, the paper likely contributes to circular economy and regional nutrient self-sufficiency objectives in European farming systems.
UK applicability
The findings may be relevant to UK sewage nutrient recovery policy and regional food-waste-to-fertiliser initiatives, though implementation would need to account for UK regulatory frameworks around biosolids and fertiliser standards. German regional infrastructure models may offer transferable lessons for decentralised nutrient cycling in the UK context.
Key measures
Collection efficiency, nutrient composition of recycled fertiliser, regional-scale feasibility metrics, and likely nutrient recovery rates from human excretion
Outcomes reported
The study examines systems and approaches for collecting human excreta at regional scale and converting it into usable recycling fertiliser products. As suggested by the title and journal focus, the work likely addresses technical, logistical and resource recovery aspects of human waste nutrient cycling.
