This study presents the data of a sludge biodrying plant reducing
the total sludge weight by 73% hence decreasing costs associated
with transport and treatment of sludge. Several internally
generated resources were reused and recycled. In the facility
9.3MW heat and 7.3 kton of a 40% (v/v) ammonium sulphate solution
were recovered per year. The final product had a high caloric
value hence offering a good replacement for brown coal and met
the European microbial and heavy metal quality standards needed
for an application as organic fertilizer. This process creates a mindset
that sludge can be seen as resource rather than simply as waste.
