Comparison of energy and material recovery of household waste management from the environmental point of view – Case Kaunas, Lithuania

The results of life cycle assessment of five different energy recovery-based waste management system options are presented. The system options were designed for the city of Kaunas, Lithuania. The Kaunas model was formed according to the Simple Integrated System Management concept developed at Lappeenranta University of Technology. CML2001 was selected as the method according to which the life cycle impact assessment profiles were compiled and analyzed.The results suggest that energy recovery from biowaste, paper and cardboard derived from households could be a more recommendable waste management option than material recovery of the fractions (composting of biowaste and recycling of paper and cardboard). The calculations were carried out with limited process information, and cannot thus be generalized in all parts.
