Agricultural fertilizer from sewage

10 May 2019

As part of close cooperation with Biopolinex and the Institute of Nuclear Chemistry and Technology has established contact with the authorities of the commune in which the sewage treatment plant is located in order to implement the research project. Its purpose is to conduct laboratory tests of the sewage sludge hygienization process for their use as a highly effective agricultural fertilizer, rich in organic components and phosphorus.

This project is carried out as part of the so-called ICHTJ so called Coordinated Research Project, "Radiation Inactivation of Bio-Hazards Using High-Powered Electron Beam Accelerators" (F23033), which is implemented as part of the Department of Science and Applications program of the International Atomic Energy Agency in Vienna, Austria. Partners in the IAEA's activities are:

Instituto de Pesquisas Energeticas e Nucleares (IPEN-CNEN/SP), SÃO PAULO, BRAZIL;

Institut national de la recherche scientifique (INRS), QUÉBEC CANADA;

Fraunhofer-Gesellschaft zur Förderung der Angewandten Forschung e.V.,Munich, GERMANY;

Institute of Isotopes Co., Ltd.; Hungarian Academy of Sciences, BUDAPEST, HUNGARY;

Korea Atomic Energy Research Institute KAERI,DAEJEON, KOREA, REPUBLIC OF;

Kuwait Institute for Scientific Research (KISR), SAFAT, KUWAIT;

Institute of Nuclear Chemistry and Technology, Warsaw, POLAND;

Centro de Ciências e Tecnologias Nucleares, Instituto Superior Técnico, Bobadela, PORTUGAL;

National Centre for Nuclear Sciences and Technologies (CNSTN), Sidi Thabet, TUNISIA;


National Center For Radiation Research and Technology, Atomic Energy authority, Cairo, EGYPT.


Each of these institutions conducts its own research, and the motive combining this work is the use of ionizing radiation in combating biological contamination of soil, water or other objects of daily use.


There are over three thousand municipal sewage treatment plants in Poland. Each of them produces sludge that can be successfully used for fertilizing soils. Municipal waste water from agricultural areas is treated using the activated sludge method. Sludge is a very good biomass that can be used for the production of electricity and heat, and bio-fermentation used as a safe organic fertilizer. In addition to chemical compounds used to fertilize the soil, it is a source of organic matter and phosphorus. Agricultural utilization of sludge is the only source of secondary phosphorus recovery. During the methane fermentation process, sludge mineralization occurs. Fermentation is not sufficient, however, because it does not completely eliminate biological contamination. An additional process for the elimination of biological contamination is the process of hygienization by an electron beam emitted from an industrial electron accelerator. Electron beam method, successfully used in the sterilization of medical equipment causes removal of microbial contamination and degrades approximately 95% of pharmaceutical residues in wastewater. Laboratory tests are aimed at determining the possibility of using innovative technology of sludge hygienization and treatment for fertilizer use, developed jointly by the Institute of Nuclear Chemistry and Technology in cooperation with Biopolinex, as part of a broader program on the use of electron beams in environmental protection. As part of the research, the sludge will undergo fermentation, hygiene and treatment. The tests should determine the sediment fertilizer values. The economic assessment for the application of the above technology will also be confirmed. The technology is the subject of an ICHTJ patent application in which one of the co-authors is an employee of Biopolinex. The invention was awarded the gold medal at the IWIS 2017 invention exhibition and the 2017 Golden Laurel of Innovation - NOT.


The City Hall in Bychawa expressed willingness to cooperate in the implementation of the project. The sewage treatment plant in Bychawa can be a precursor of a new solution and a place where new technology can be initiated, which is a unique solution on a global scale. Attached is a letter regarding possible cooperation with the city of Bychawa and a presentation on the invention.
