SEWAGE SLUDGE BECOMES A PHOS­PHORUS FERTI­LIZER

Stricter limits, obli­ga­tion to recycle phos­phorus, rising waste disposal costs due to capa­city bott­len­ecks: The recy­cling of sewage sludge is beco­ming increa­singly sophisti­cated. We support you with our leading-edge carbo­ni­sa­tion tech­no­logy: With a PYREG system, the dried sewage sludge is carbo­nised, hygie­nised and comple­tely recy­cled into a phos­phorus ferti­liser substrate approved throughout Europe. The tech­no­logy has already proven its worth at three waste­water treat­ment plants in Germany and the USA, but is worth 50,000 p.e. (popu­la­tion equi­va­lent).
OUR TECH­NO­LOGY. YOUR BENE­FITS.
The P500 for sewage sludge is a compact plant in series produc­tion and fulfils all necessary approval guide­lines with its exhaust gas puri­fi­ca­tion system.
In the PYREG process, the sewage sludge is comple­tely recy­cled into a ferti­liser substrate with plant-avail­able phos­phorus that is approved throughout Europe. Further treat­ment is not necessary.
A PYREG system is desi­gned as a decen­tra­lised sewage sludge recy­cling solu­tion: The sewage sludge can be used where it accu­mu­lates – directly at the sewage treat­ment plant. This saves complex logistics (volume reduc­tion by more than 60%). The system can also be scaled up as required.
With the decen­tra­lised PYREG tech­no­logy, all recy­cling steps remain in one place and you can calcu­late, plan and control the process in a targeted manner.

FOR CLIMATE AND ENVI­RON­MENT

The carbo­ni­sa­tion of sewage sludge may seem to go against the trend in the age of “decar­bo­ni­sa­tion”. Rest assured: Exactly the oppo­site is the case. With carbo­ni­sa­tion you actively protect the envi­ron­ment and the climate.

ADVAN­TAGES

The sewage sludge is ther­mally treated and hygie­nised. Hormones, germs, drug resi­dues, micro­plasty or the like are elimi­nated.
The recy­cling process is auto­thermal, only energy from the sewage sludge is used to operate the plant.
Phos­phorus is reco­vered as a secon­dary raw mate­rial in a form avail­able to plants.
During carbo­ni­sa­tion, a large part of the carbon contained in the sewage sludge is bound over the long term and spread as ferti­liser substrate, seques­tered in the soil for centu­ries.
