PURPOSE AND SCOPE
In April 1992 the First International Symposium on Anaerobic Digestion of Solid Waste (ISAD SW'92) took place in Venice. It was a success with more than 250 attendees from around  40 countries. Since that time, new developments and research have occured, some plants have been constructed, problems have been identified, and at the same time, legislation has evolved in a direction favourable for this technology. Although the symposium is focused on 'solid' organic wastes in general, the organic fraction of Municipal Solid Waste (MSW) is the most relevant.  Many landfills are due to close and there is a significant increase of separate collection of  MSW. These organic wastes need to be treated by biological methods, in order to promote recycling and maximum recovery of its components. Composting and Anaerobic Digestion are the most appropriate technologies. A session discussing when these technologies are best applied is included. Other organic wastes, such as agro-industrial solid and liquid sludges as well as leachates are also present in this extended scenario, offering opportunities for integrated treatment approaches. Therefore is considered very appropriate to celebrate a new edition of this international symposium, expanded to include topics such as:

· Fundamentals: Kinetics, Microbiology, Toxicity.
· Dynamics and Modelling
· Monitoring, Control and Instrumentation. Real time measurements
· Hydrolysis as a key step in  solids methanization.
· Reactor Design and Performance.
· Co-digestion with other wastes
· Production of chemicals from solid wastes.  Use of by-products
· Pre-treatments and finishing treatments (composting, dewatering, etc.)
· Composting vs. Anaerobic Digestion of organic solid wastes
· Treatment of process wastewater from AD of solid wastes
· Industrial and Commercial Applications: Full-scale experience.
· Fundamental aspects of methanization in landfills. Anaerobic digestion of  leachates.
A Poster Session but no exhibition is included
