An assessment of the current and future options for domestic waste management in Kaunas, Lithuania

摘要

The main purpose of this study was to carry out a retrospective analysis of solid waste generation in Kaunas city from 1994 to 2003 and to calculate the theoretical waste generation in the future. This paper also presents measurements of the annual variations of waste amounts and calculations on a theoretical waste incineration facility. Two waste treatment scenarios were considered. Scenario A: waste deposit at the landfill with 'implementation of domestic waste separation and recycling'. Scenario B: waste removal to a landfill with 'multi-treatment: household separation, recycling and energetic recovery'. Three levels of waste treatment were proposed. The first level was implementation of the recycling system, which included household waste separation. The next step involved mechanical-biological treatment. The third level was the construction and operation of a new waste incineration plant in Kaunas. Two sites in Kaunas city were proposed; however, more detailed analysis, including the economic factors, will need to be done.
