GHG reduction potential in waste management in Croatia

The purpose of this paper is to examine a greenhouse gas (GHG) emission reduction potential from different waste management practices in Croatia. Energetic, environmental and economic benefits can be accomplished by utilizing municipal solid waste (MSW) and landfill gas as fuel in industry and energy sector, which is emphasized in this paper. The paper gives an overview of measures for energy recovery from MSW and landfill gas that could be implemented in Croatia. These measures also represent measures for an additional GHG emission reduction by decreased use of fossil fuels.

A methodology used for emission calculation (kinetic model) is explained. Three different scenarios of GHG reduction in waste management were defined. Implementation of best available techniques in waste management is envisaged by cross‐sectoral impact and effect of respective measures. Findings –This paper gives maximum achievable potential of GHG emission reduction with defined measure implementation dynamics. It was calculated that around one million ton of CO₂ can be avoided in 2020, which is 2.7 percent of projected GHG emissions in Croatia. The energy that could be recovered from waste (8.34 PJ in 2020) is relatively small in relation to the total final energy consumption in Croatia (about 3 percent).

The novelty of this work is achieved through integrated approach to GHG emission reduction and energy potential from MSW management in Croatia. The GHG reduction potentials are calculated by taking into account dependencies and interactions between the measures.
