ESPOO 2002 VTT SYMPOSIUM 222 The expert meeting on Power Production from Waste and Biomass IV, with VTT SYMPOSIUM 222 emphasis on advanced concepts and technologies, was held on 8–10 April 2002 in Espoo, Finland. The meeting was organised by VTT Processes in co- operation with EC DG TREN, Novem, IEA Bioenergy Task 36, Tekes and the Finnish Ministry of Trade and Industry. In Europe, several directives will set targets for future waste policy. The directive on landfilling will reduce significantly the volumes of combustible fractions. On top of traditional massburning of mixed waste, there is a need for advanced concepts with higher material recovery and higher efficiency in energy production. In the future, instead of mixed municipal solid waste, quality Power production from waste and biomass IV. Advanced concepts and technologies controlled recovered fuels will be produced and used as such or co-fired in existing power plants. The target of increasing renewable energy production in Europe from 6 to 12% by 2010 will boost R&D, future investments and business opportunities. Modern waste treatment practices will have an important role to play in meeting the goals of the Kyoto Protocol. Indicative of the interest in power production from waste and bioenergy was the participation of about 160 specialists from 19 countries. Industrial companies were well represented, indicating the existence of good business opportunities in this field. The next meeting on power production from waste and biomass will be organised in 2005.

The meeting was organised by VTT Processes in co-operation with EC DG TREN, Novem (from the Netherlands), IEA Bioenergy Task 36, Tekes and the Finnish Ministry of Trade and Industry. Overviews of the European waste policies, waste management and waste-to- energy practices were given. Most of the relevant directives were presented including the directive concerning integrated pollution prevention and control (IPPC). The directive on waste incineration and its practical implications for fluid bed combustion and gasification of solid recovered fuels were discussed actively in the meeting. An overview of traditional massburning of mixed waste was given. The main focus, however, was on advanced process concepts and technologies. For example, in Finland, recovered fuel production and cofiring, based on either direct combustion in fluid bed boilers or pregasification, have been introduced successfully at several power plants. Fuel specifications are controlled by the Finnish recovered fuel standard. In Europe, a project for preparing the future CEN standard was presented and discussed. Experiences and R&D activities in the areas of fluid bed combustion and gasification, including gas cleaning and monitoring practices, were presented. Modern waste-to-energy concepts will play an important role in advanced waste management business concepts. Future integrated waste recycling and energy production concepts, based on source separation and recovered fuel production, were presented. New R&D results were also presented concerning additional paper and plastic recovery from commercial and industrial waste, typically packaging waste. National waste management policies and practices in the Netherlands and in Finland were presented based on the bilateral information exchange between Novem of the Netherlands and Tekes of Finland. The proceedings include the presentations given by the key speakers and other invited speakers, as well as papers based on some of the poster presentations. 3 Preface The seminar on Power Production from Waste and Biomass IV, with emphasis on advanced concepts and technologies, was held on 8–10 April 2002 in Espoo, Finland. The previous seminars organised by VTT had been held in December 1992, March 1995 and September 1998 and the proceedings of these seminars have been published in the VTT Symposium series. The meeting was organised by VTT Processes in co-operation with EC DG TREN, Novem (from the Netherlands), IEA Bioenergy Task 36, Tekes and the Finnish Ministry of Trade and Industry. Results of the Finnish Waste-to-Energy R&D Program were presented. The Program constituted 60 projects with a total budget of 16 million euros. Additional information is available at www.wastetoenergy.vtt.fi. Key results of the Dutch – Finnish information exchange, supported by Novem and Tekes, were presented by Ir. Kees Kwant of Novem. In Europe, several directives will set targets for future waste policy. The directive on landfilling will reduce significantly the volumes of combustible fractions; several countries have already set a total ban on the landfilling of combustible material. On top of traditional massburning of mixed waste, there is a need for advanced concepts with higher material recovery and higher efficiency in energy production. In the future, instead of mixed municipal solid waste, quality controlled recovered fuels will be produced and used as such or co-fired in existing power plants. The directive on waste incineration will set tight limits on emissions. A significant part of future investments aimed at reducing landfill waste volumes will be allocated to waste-to-energy projects. The directive on electricity production from renewable energy sources will catalyse green power production from the biogenic waste fractions. The target of increasing renewable energy production in Europe from 6 to 12% by 2010 will boost R&D, future investments and business opportunities. Modern waste treatment practices will have an important role to play in meeting the goals of the Kyoto Protocol. 4 Indicative of the interest in power production from waste and bioenergy was the participation of about 160 specialists from 19 countries. Industrial companies were well represented, indicating the existence of good business opportunities in this field. The next seminar on power production from waste and biomass will be organised in 2005. Espoo, April 2002 Kai Sipilä 5 Contents ABSTRACT 3 PREFACE 4 Overview of EU waste to energy aspects and RES 9 K.
