Abstract:
The acceleration of urbanization phenomena in many countries increases the generation of municipal solid waste. One of the
biggest problems that Romania encountered before and after the entrance in the European Union is the waste management related
to an increasing generation and the necessity to comply with the European directives. An important requirement regards the
reduction of the amounts of landfilled biodegradable material. Where landfilling is widely used, the most serious environmental
problems, both for Romania and for the other countries, are connected to the biogas and leachate production in the landfill and the
related pollution. The present paper wants to study some options (pressing, anaerobic digestion, bio-stabilization) for the
treatment of municipal solid waste before landfilling in sanitary landfills. Data regarding mass, volume, energy and environmental
balances are presented. Taking into account the local requirements additional scenarios can be analyzed in order to
increase/modify the information available for the decision makers.
