PREFACE 
The sixth European Conference on Biomass for Energy, Industry and Environment was 
held in Athens by kind invitation of the Greek authorities and with the collaboration of 
Unesco, the Center of Renewable Energy Sources and of the Fertec-Novamont. 
This Biomass conference was held in April’ 91, just after a period of high international 
tension consecutive to the Gulf crisis. These events stressed the fact that conventional 
energy sources are more and more concentrated in restricted regions of the world with 
high geo-political unstability. 
In this context, the world biomass potential appears as a significant alternative for 
energy  and  industry,  with  an  important  contribution  to  a  global  environmental 
improvement (greenhouse effect, acid rains, forest fires control…) and to the P.A.C. 
Some 400 participants from all over the world attended the conference with, for the 
first time, the participation of researchers and experts from Eastern Europe. 
The conference was organised on the basis of oral sessions, round-tables and poster 
exhibitions representing the different stages of production, conversion and utilisation of 
biomass including the socio-economic and environmental aspects of this resource. 
As this conference occurred two years after the starting of the R&D programme of the 
Commission in this field, many results were presented demonstrating a high level of 
scientific and technical contribution. 
Consequently, this book represents a wide synthesis of the most recent biomass R&D 
progress throughout Europe and in the world, offering to industrialists, researchers and 
decision makers, a supplementary instrument to furthermore support the development of 
innovative, modern technologies and concepts. 
Finally, on behalf of the organisation and scientific committee, we would like to thank 
all our Greek hosts and all those who contributed to the success of this conference.
