SEWAGE SLUDGE AT ITS BEST:
CARBONIZED TO A PHOSPHORUS FERTILIZER

The requirements for disposal of sewage sludge are an international issue. In many countries sewage sludge regulations are expected to be modified shortly, so that spreading of untreated sewage sludge
on agricultural land may be prohibited in the near future. And recycling of phosphorus from sludge will become mandatory in many countries. In Germany further restrictions will result from the Fertilizer Ordinance comprising several prescriptions issuing from European Nitrates Directive.

PYREG has developed an innovative and decentral recycling method, which is able to recycle the sewage sludge completely, i.e. transforming it energetically and materially to phosphorus fertilizer. This process does not only sanitize the sewage sludge, but also significantly reduces its quantity and delivers phospho- rus as a recycling product. The PYREG® technology is a decisive investment to ensure a long-term safe disposal, independence and reduced transport cost.
