research project abonoCARE®

Procedural development and implementation of laboratory and semi-technical scale incineration experiments for the reduction of pollutants and enrichment of phosphor in fertilizer pre-products

Funding:	BMBF
Partners:	Fraunhofer-Institute for Ceramic Technologies and Systems (IKTS) (IKTS), LTC - Lufttechnik Crimmitschau GmbH
Duration:	April 2019 - December 2022

Project description:

As a fertilizer, Phosphorus is irreplacable in agriculture. However the world‘s resources are limited. Since municipal sewage sludge contains a significant amount of phosphorus, various recovery technologies have already been developed and tested. However, these go hand in hand with a high input of energy and cost.

The project aims to develop a combustion technology that produces low cost fertilizers from sewage sludge and regionally available organic residues that are high in nutrients and low in pollutants.

Combustion tests are carried out in the small-scale furnace and in the semi-stationary fluidized bed incinerator VERENA. The effects of additives on the content of heavy metals and phosphorus in the resulting ashes are investigated.

In addition to the mono-incineration of sewage sludge an integrated hot-gas filtration for the seperation of modified ashes is realized and tested in a laboratory scale .

 Within AbonoCARE^® a range of products, technologies and services is being researched and developed in the region of Central Germany. The objective is to establish recycled fertilizers as an alternative to conventional ones and to promote sustainability and the regional economy.
