Perspectives are different frameworks from which to explore the knowledge around sustainable sanitation and water management. Perspectives are like filters: they compile and structure the information that relate to a given focus theme, region or context. This allows you to quickly navigate to the content of your particular interest while promoting the holistic understanding of sustainable sanitation and water management.
ASH DEC Umwelt AG, currently Outotec, operates manufacturing plants to recycle nutrients and metals from incineration residues. The focus of interest is the production of phosphorous-fertilisers and –raw products from sewage sludge ash with the patented ASH DEC technology.

This thesis proposes a new global goal – phosphorus security – to be integrated in the dominant research discourses and policy debates on global food security and global environmental change. Among other criteria, phosphorus security requires that phosphorus use is decoupled from environmental degradation and that farmers’ access to phosphorus is secured.
