Cost-Effectiveness of Measures for GHG Emission Reduction and Energy Recovery in Waste Management in Croatia

Many of the modern practices in waste management at the same time represent means of reduction of greenhouse gas (GHG) emissions. This paper analyzes the economic side of the implementation of such measures in order to determine the priority between them. Respecting cost-effectiveness, marginal costs (expressed as EUR per ton of reduced or avoided CO2eq) were calculated for the following measures: Utilization of landfill gas for electricity production, Utilization of refuse derived fuel (RDF) in cement industry, Landfill gas flaring, Thermal treatment (Incineration) of MSW, and Mechanical-biological treatment. It was calculated that around 1 million ton of CO2 can be avoided in 2020, which is 2.7% of projected GHG emissions in Croatia, while the energy that could be recovered from waste is 8.3 PJ in 2020, which is about 3% of the total final energy consumption (in 2008). The measures Utilization of landfill gas for electricity production and Landfill gas flaring showed the greatest economic benefit.
