Report on the first Project Co-ordination Meeting of the Project Sfp-973720

(September 11, 2001)

 

The meeting took place in Bologna from 10th September to 11th September 2001. The following project participants joined the meetings:

Dr. Bjorn-Arne Johnsen (NATO consultant)

Prof. Fabio Fava (NPD, Bologna Univ., BU, Italy)

Dr. Lorenzo Bertin (Bologna Univ., BU, Italy)

Dr. Diana Di Gioia (Bologna Univ., BU, Italy)

Prof. József Szejtli (PPD, Cyclolab, CYL, Hungary)

Dr. Éva Fenyvesi (Cyclolab, CYL, Hungary)

Ms. Katalin Laszlo (Cyclolab,CYL, Hungary)

Dr. Katalin Gruiz (Project Co-Director, Budapest Univ. of Technology and Economics, TUB, Hungary)

Ms. Mónika Molnár (Budapest Univ. of Technology and Economics, TUB, Hungary)

Ms. Zita Szechenyi Nagy (Budapest Univ. of Technology and Economics, TUB, Hungary)

Ms. Laura Leitgib (Budapest Univ. of Technology and Economics, TUB, Hungary)

Dr. Attila Murányi (Project Co-Director, Hung. Acad. Sci., RISSAC, Hungary)

 

The Co-Directors of the Project as well as some young scientists belonging to the different teams presented their research work according to the meeting schedule attached. After each presentation, an extensive discussion took place, both NPD and NATO consultant verified that the presented works were in agreement with the Progress Report sent to NATO in May 2001 and with the Project Plan accepted in November 1999.

During both the “Evaluation of the progress of the project: achievements, milestones” session (presented  by Proff. J. Szejtli and F. Fava) and during the successive discussion session it clearly arose that:

·        the research work jointly performed by the different project units was of high quality and in agreement with the proposed milestones. For instance, Phase 2 experiments have been concluded at BU, where Phase 3 work is going to be finished within Nov. 2001; TUB and CYL concluded both Phases 3 and 4; in addition RISSAC performed an interesting basic research on the effect of RAMEB on soil constituents; finally, Phase 5 experiments have been started in the field through an ex-situ approach (by using soil coming from a selected contaminated industrial place); 

·        the results obtained are original and they can contribute significantly to the knowledge on cyclodextrin-effects on the bioremediation of soils containing different mixtures of hydrophobic organic pollutants;

·        the data obtained strongly support the idea that cyclodextrins can significantly enhance the aerobic biodegradation of hydrocarbons and polychlorinated biphenyls in artificially- and aged-actual site contaminated soils. Cyclodextrins resulted to have great potential in the field of bioremediation of such soils, as they are able to conjugate relevant pollutant solubilization properties with a non toxicity and a good biodegradability in the soils;  

 

·        an important dissemination of the results has been continued: in addition to a number of scientific communications presented at international and national conferences, 2 scientific papers have been already submitted to average- or high-level international scientific journals for publication;

·        an effective exchange of knowledge and experience occurred between the non-NATO and NATO country units involved in the project. The young researchers also joined the Training Course on “Biological degradation of polychlorinated biphenyls in contaminated soils and sediments” organized by Fabio Fava at the University of Bologna on Sept. 7 and 8, 2001 (please, see the attached schedule). 

·        the contribution of the young scientists in the research was relevant and essential.

1. Site for the field experiment

On the basis of the data collected through the assessment of the former military base in Dunaújváros (see Progress Report No.1 at page 16 and Table II at page 18), the actual contamination occurring in the three selected sites was found to be too low to use them for testing the new cyclodextrin-based technology.

Hungarian units are making much effort to find a new site for the in-situ experiment. They have already applied for the permission from the Authority to perform the experiment in two different contaminated sites, i.e., the transformer station in Budapest and the other one in former Soviet military base located in Kiskunlachaza. They are still waiting the final definitive permission.   In any case, the ex-situ experiments currently in progress are carried out in the originally selected place in Dunaújváros, for which the required permission was obtained.

 

2. Technological approach used in the ex-situ experiments currently in progress.

Some un-expected phenomenon arose from the technological ex-situ experiments currently in progress in the former military base. In particular, the formation of dark coloured products on the soil surface was often observed in the presence of cyclodextrins. The phenomenon was carefully discussed, and the scientists joining the meeting decided to develop and to test new technological approach for supplying cyclodextrins to the soil under treatment.

 

3. Prof. J. Szejtli informed the participants in the meeting that the cost of the technical-grade cyclodextrins that are currently used in the research work is descending significantly and that, therefore, the cyclodextrin-assisted bioremediation technology that is under development in this SfP project may be cost-effective.

Report on the Project Co-ordination Meeting of the Project Sfp-973720

(3 October, 2002)

 

The meeting took place in Budapest from 30th September to 2nd October 2001. The following project participants joined the meetings:

Dr. Bjorn-Arne Johnsen (NATO consultant)

Prof. Fabio Fava (NPD, Bologna Univ., BU, Italy)

Dr. Lorenzo Bertin (Bologna Univ., BU, Italy)

Prof. József Szejtli (PPD, Cyclolab, CYL, Hungary)

Dr. Éva Fenyvesi (Cyclolab, CYL, Hungary)

Ms. Nikoletta Szaniszlo (Cyclolab,CYL, Hungary)

Dr. Katalin Gruiz (Project Co-Director, Budapest Univ. of Technology and Economics, TUB, Hungary)

Ms. Laura Leitgib (Budapest Univ. of Technology and Economics, TUB, Hungary)

Dr. Attila Murányi (Project Co-Director, Hung. Acad. Sci., RISSAC, Hungary)

 

The Co-Directors of the Project presented their research work according to the meeting schedule attached. After each presentation, an extensive discussion took place, both NPD and NATO consultant verified that the presented works were in agreement with the Progress Report sent to NATO in May 2002 and with the Project Plan accepted in November 1999. As this was the last annual meeting of the project, a final evaluation of the results was presented by the participating Co-directors.

During both the “Evaluation of the progress of the project: achievements, milestones” session (presented by Profs. J. Szejtli and F. Fava) and during the successive discussion session it clearly arose that:

·        the research work jointly performed by the different project units was of high quality and in agreement with the proposed milestones. For instance, Phase 3 experiments have been concluded at BU; having finished the Phase 1-4 experiments TUB and CYL are performing the field experiments both ex situ and in situ; in addition, RISSAC continued to perform an interesting basic research on the effect of RAMEB on soils.

·        the results obtained are original and they contribute significantly to the knowledge on cyclodextrin-effects on the bioremediation of soils containing different mixtures of hydrophobic organic pollutants;

·        during the step by step scaling up from the laboratory experiments to the field trial, the data obtained strongly support the idea that cyclodextrins can significantly enhance rate and sometimes the extent of the aerobic biodegradation of hydrocarbons and polychlorinated biphenyls in artificially- and aged, actual site contaminated soils by activating and/or sustaining the pollutant degrading microflora, by decreasing the adaptation period, by enhancing the bioavailability of the substrates; by changing the toxicity; by affecting the morphology of the soils;

·        the participating teams collected solid evidence on the biodegradability of the cyclodextrin used in the experiments, which was a previous concern on the data of the manufacturer producing this additive;

 

·        an important dissemination of the results has been continued: in addition to a number of scientific communications presented at international and national conferences (8 and 9, respectively), 2 scientific papers have been already published, another 4 has been accepted for publication and an additional one has been submitted to a high-level international scientific journal;

·        an effective exchange of knowledge and experience occurred between the non-NATO and NATO country units involved in the project. This is also documented by the fact that some of the papers and presentations have Hungarian and BU co-authorships. The young researchers joined the Training Course on “Biological degradation of polychlorinated biphenyls in contaminated soils and sediments” organized by Fabio Fava at the University of Bologna on Sept. 7 and 8, 2001 as well as the Training Course on “Biological degradation of hydrocarbons in contaminated soils” organized by Katalin Gruiz at the Budapest University of Technology and Economics in Budapest, September 30-October 1, 2002. (The latter training course was held preceding the annual meeting with the participation of 24 people including students and young scientists from two universities, an academic and a governmental institution, as well as from 4 companies; the program of the training has been attached to this report).

 

·        the contribution of the young scientists in the research was relevant and essential.

1. Financing the field experiment

On the basis of the data collected through the assessment of the former military base in Dunaújváros (see Progress Report No.1 at page 16 and Table II at page 18), the actual contamination occurring in the three selected sites was found to be too low to use them for testing the new cyclodextrin-based technology. The company working on this site (TDT-3R, Ltd.) was involved in the project as participant, and the manager (Edward Someus) as a Project Co-Director. His budget was planned to use for both the ex situ and in situ experiments. As he could perform only the ex situ experiment because of the lack of contamination at the site, his residual budget planned originally for the expenses of the in situ experiment should be transferred to the company which is performing the in situ experiment in another site.

Hungarian units have made much effort to find a new site for the in-situ experiment. Having got all the necessary permissions the in situ experiment started at a transformer station in Budapest in the middle of June. This strongly contaminated site belongs to the National Electric Company, and is being decontaminated by a REM-FWS Ltd. (Budapest, HU). The in situ experiment is therefore performed by Hungarian project research Units in strict cooperation with REM-FWS Ltd, a company which was originally not involved in the project. Cyclolab should pay for the set-up and maintenance of the experiment, for rental of the necessary equipments (filter units, sedimentation unit, ventilator, pumps). The half of the expenses have been covered by Cyclolab from the national contribution obtained from the Ministry of Education. For the other half, the residual budget of Mr. Edward Someus should be used. The participants at the meeting, as well as the NPD and the NATO consultant agreed upon this solution of the financing the in situ experiment, and Mr. Edward Someus (the referent of the budget which should be moved to Cyclolab) has earlier expressed his consent, too.

Prof. Fava, NPD, was asked to further discuss and to arrange this budget transfer with NATO SfP office.

2. All project co-directors have expressed a positive opinion on the effectiveness and the quality of the new project web-site; therefore, they jointly asked to Prof. Fava to arrange (with the NATO SfP project) the payment of 20,000 BEF to Mr. Someus’s team for the establishment and maintenance of the web-site, as jointly decided during the first project meeting in Budapest (2000);

3. The preparation of the final report was also discussed, and the topics of the subchapters in the scientific report decided. Prof. Fava was asked to get information from NATO SfP Office on the deadline for the preparation.

4. Prof. Fava finally underlined the opportunity to organize two workshops strictly focused on the final results of the joint research program during the next two years (2003, 2004). One can be organized in Budapest, possibly on the site where the field experiment will be completed at the end of this year, and the second one in Bologna (Italy). These two workshops, where the original aims of the project along with all the results collected during the 3-years project would be presented and discussed, would allow to efficiently disseminate the products of the SfP project sponsored by NATO towards the broader scientific and non-scientific Hungarian and Italian communities. All participants in the meeting, including the NATO consultant, agree on the usefulness of this initiatives, that all of them have evaluated as an excellent way to implement the results achieved within the project; however, some of them have mentioned that a budget is necessary for allowing the chiefs of the 5 research units joining the project to travel for participating in the two workshops (4/5 people have to move in Italy for the workshop in Bologna and 1 person has to move in Budapest for the other one). As this budget was not contemplated in the original project plan and therefore it is not available in the budget that NATO allocated for each unit, Prof. Fava gave his availability to discuss the idea of these two workshops and the potential strategy for finding out a small extra budget dedicated to them with the NATO SfP office.
