Institute of Chemical Products and Nuclear Technologies, under close cooperation with the company Biopolinex, has established contact with the authorities of the town of Bychawa in order to pursue a project concerning laboratory tests of the sewage sludge hygienization process to use such sludge as a highly effective agricultural fertilizer, rich in organic ingredients and phosphorus. This project is conducted under, obtained by ICHTJ, the so-called Coordinated Research Project, “Radiation Inactivation of Bio-Hazards Using High-Powered Electron Beam Accelerators” (F23033) which is realized under the program of the Department of Science and International Applications of the Atomic Energy Agency in Vienna, Austria. The partners in MAEA activities are: Comision Nacional de Energia Atomica (CNEA), BUENOS AIRES, ARGENTINA; 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; Texas A&M AgriLife Research, COLLEGE STATION, TX, UNITED STATES; National Center For Radiation Research and Technology, Atomic Energy authority, Cairo, EGYPT…. Each of these institutions runs its own research, and the motive connecting these works is using ionising radiation for counteracting biological contamination of soil, waters or other daily use items.


In Poland, there are more than three thousand municipal wastewater treatment plants. Each of them produces a deposit which can successfully be used for soil fertilization. Municipal sewage from agricultural areas is cleaned using active sediment methods. Deposit is very good biomass which may be used for electric and thermal energy generation and the bioferment used as a safe organic fertilizer. Apart from chemical compounds used for soil fertilization it is a source of organic matter and phosphorus. Agricultural use of sludge is the only source of secondary phosphorus recovery. During the methane fermentation process, sludge is mineralized. However, fermentation is not sufficient, as it does not completely eliminate biological contamination. An additional biological contamination elimination process is the hygienization process by the method of an electron bundle emitted from an industrial electron particle accelerator. The electron bundle method, successfully used in sterilization of medical equipment, removes microbiological contamination and degrades traces of pharmaceuticals in sewage in approximately 95%. Laboratory tests are intended to determine the possibility to apply the innovative technology of sludge hygienization and their cleaning in order to use them as a fertilizer, developed jointly by the Institute of Chemistry and Nuclear Technologies in cooperation with Biopolinex, as part of a broader program concerning electron bundle application in environmental protection. Under the research, the deposit will be subjected to fermentation, hygienization and treatment. The research should specify the sludge fertilizer values. The economic assessment of will also be confirmed for the application of the above mentioned technology. Technology is the subject of ICHTJ’s patent claim, in which one of the co-authors is a Biopolinex employee. This invention has obtained the gold medal on IWIS 2017 inventions exhibition and the Golden Laurel of Innovation 2017 – NOT.


The Municipal Office in Bychawa has expressed the willingness to cooperate in the project implementation. The sewage treatment plant in Bychawa can be the precursor of the new solution and the place where a new technology can be initiated, which is a unique solution worldwide.Enclosed please find a letter concerning start of possible cooperation with the town of Bychawa and a presentation concerning the invention.
