Project objectives:
The FP6 project SUSAN started in November 2005 with the aim to develop technologies and strategies for safe and efficient recovery of nutrients as fertilisers 
from municipal sewage sludge. The project focused on developing and validating a thermo-chemical process enabling heavy metals removal and transfer of phosphorus
into mineral phases with high bioavailability. This technology was intended to be suitable for large scale facilities handling up to 50,000 tons of ashes per
year.
Project Summary:
Municipal sewage sludges are often highly polluted with organics, such as hormones, antibiotics, endocrine disruptors, persistent organic pollutants 
(POPs), and inorganics such as heavy metals e.g. cadmium, chromium, copper, nickel, mercury and zinc. In the last couple of years, the agricultural application
of sewage sludge has decreased in the European Union, while the interest in alternative sludge disposal routes to protect farmland and human health has increased.
However, following this strategy, nutrients (most notably phosphorus) are irreversibly lost and the need for mineral fertiliser products will increase.
The scarce resource phosphorus could be recovered if a sound recycling strategy is developed and applied.
Achieved Objectives:
So far, the investigations demonstrated the capability of the proposed    
technologies including efficient heavy metal removal and conclusive    
increase of phosphorous bioavailability in the treated ashes.
