Visit in Deutsche Montan Technologie GmbH (DMT), Germany

Visit in Centre de Pyrolyse de Marienau (CPM), France

• DMT – a fully commercial organization, does not have extra money for additional research program. The cooperation was supposed to be closely connected with current research or service tasks.• Research within the framework of internships was supposed to concentrate on thermal utilizationof waste plastics or on sewage sludge treatment. • The scope of technical cooperation range should have been conducted in “Modern Fuels Unit”.

• CPM - a fully commercial organization, does not have extra money for additional research program. The cooperation is supposed to be closely connected with current research resulting in commercial product. • CPM proposed participation of its individual researchers in conferences and seminars planned in the project and suggested the scope of their presentations. • Topics for bilateral cooperation within the framework of young researcher internship in CPM has been selected.

Visit in Consejo Superior de Investigaciones Cientificas (CSIC), Spain

• The scope of technical research was negotiated. The research will concentrate on pyrolysis of rubber waste. Pyrolysis tests in both fixed bed (8 tests in IChPW) and fluidized bed (4 tests in CSIC) were suggested. Products’ (mainly solids) properties analysis will be conducted in laboratories of both research centres. • The date of Mr. Sławomir Stelmach’s arrival for a three-month scientific internship at CSIC was discussed. CSIC suggested the internship period: March-May 2004.• The Spanish centre proposed participation of its researchers in conferences and seminars planned in the project. The scope of their presentation is described and will be approved in the form of Technical Annex.

Visit of Prof. A. Mastral (Consejo Superior de Investigaciones Cientificas, Spain) in Poland 18 -22.05.2003

The visit included working meetings in IChPW and participation in the conference “Combustion and Gasification of Biomass and Wastes” in Wisła. The following aspects of cooperation were discussed:

• Thermal processing (pyrolysis) of rubber waste, especially the problem of distribution of sulphur and zinc compounds during its thermal transformation, will be the main field of cooperation between IChPW and CSIC. • Cooperation in this field should bring preparation of common application proposals for Projects within 6FP.
