The ESPP - DPP - NNP Catalogue of Nutrient Recovery Technologies summarises processes for recovery of nutrients from sewage, manure or other sources, covering technologies should be operational or demonstrated at full-scale or pilot scale, recovering phosphorus, nitrogen, potassium and/or micro-nutrients.

The catalogue aims to provide practical information on: technology supplier, process input materials, output products (nutrient content, organic carbon content and other properties), process description (inc. fate of contaminants), current operating status (number, capacity duration of continuous operation).

Information on technologies not currently included is invited, or comments or updates, to


Disclaimer: This document aims to provide an indicative overview, not technical information to support decision making. It is accurate to the best of our knowledge, but further information and updates should be sought from the indicated contacts. The information included has been discussed between ESPP and the technology suppliers, and in general validated by these companies. However, ESPP, DPP and NNP do not have resources necessary to audit information provided and information is included as provided by the companies. Inclusion in this document does not constitute any endorsement of technology(ies) by the nutrient platforms, nor validation of intellectual property nor commercial claims.
