Disposing of and returning phosphorus from sewage sludge is an important resource issue. Phosphorus is a finite resource and virgin mining and extraction means a great burden on the environment. Composted sewage sludge also works excellently as a plant layer for, for example, final coverage or as part of fly ash-stabilized sewage sludge in a waterproofing layer (FSA). Revaq-certified sludge Since 2008, Econova has been offering farmers certified sludge as a fertilizer. Sludge spreading on agricultural land presupposes that the sludge is quality assured according to the Revaq certification system . Revaq ensures that the sludge contains low levels of heavy metals and other undesirable substances. Gifts are adapted with long-term sustainability in focus. In addition, the certification also covers the municipalities' upstream work in management systems, storage under safe conditions and longer storage times for hygiene before spreading. In addition to phosphorus, the sludge also adds other nutrients and soil-forming substances to the arable land. Finishing and plant layers Econova also handles sludge that is not REVAQ-certified, but otherwise has good quality. We compost this sludge and use it for plant layers in roofing and other suitable green areas. WATERPROOFING WITH FSA We also have experience from a number of final covers with FSA, fly ash-stabilized sewage sludge, as a waterproofing layer. FSA waterproofing layers have been evaluated in a number of different trials and research programs, which has resulted in a handbook for quality assurance of FSA, among other things. We are happy to tell you more! ECONOVA'S COMPLETE SOLUTION FOR SPREADING SEWAGE SLUDGE The sludge is hygienized by storage for six months. A distribution plan is drawn up.
