Upgrading of Regional Waste Management Centre in Ljubljana

The objective of the project is to provide the city of Ljubljana and surrounding municipalities (approximately 414,000 inhabitants) with an integrated, long-term waste management system compliant with national and European legislation. It will be implemented by SNAGA Javno podjetje d.o.o., a public utility company under the City Municipality of Ljubljana in the region comprising the city and 16 surrounding municipalities.

Project description

The project covers :
1. The waste treatment facility, including:

  • Facility for treatment of mixed household waste, waste from production, trade, service sector and bulky waste with an input capacity of 150 239 t/year,
  • Facility for solid recovered fuel production with an input capacity of 60 137 t/year, and
  • Facility for treatment of separately collected biodegradable household waste with an input capacity of 21 000 t/year.

2. The leachate treatment plant, treating the leachate from the landfill and wastewater from waste treatment, with a capacity of approximately 520 m3/day.
3. Enlargement of the existing landfill cells by 50 000 m2.

What are the project likely benefits?

When constructed, the waste management centre shall contribute to a considerable reduction of the waste volume disposed at the Ljubljana landfill. 79.2% of the collected waste will be treated in the waste treatment facility, rendering the waste to be landfilled practically inert. The recycling and recovery rate of the waste shall be increased to approximately 56.8%. Reduced volumes of land-filled biodegradable waste shall contribute to reduction of greenhouse gases emissions. Biogas produced in the treatment process and at the landfill will be collected and used for production of energy.

To minimise negative impacts on the environment, wastewater from the treatment process and leachate produced in the landfill shall be treated in the leachate treatment plant. By enlarging the existing landfill cells, the operational life of the landfill shall be extended until 2015.
The project shall contribute to achievement of objectives and targets of the relevant national and European legislation. It also plays a key role in meeting the targets of the structural European structural funds 'Operational Programme for Development of Environmental and Transport Infrastructure', in particular through reducing the total quantity of disposed non-hazardous waste by approximately 176 000 t/year, and by increasing the quantities of separately collected fractions by approximately 41 000 t/year.

What are the project likely environmental benefits ?

Through the improvements to the waste treatment, the project will bring about a considerable reduction of volume of land-filled waste. Significant environmental benefits will also stem from the elimination of groundwater and subsoil contamination thanks to the sealing of the landfill, treatment of leachate and elimination of leakages. Gas from the landfill will also be captured and used to substitute for energy which would otherwise be produced from fossil sources, thereby contributing to the  reduction of greenhouse emissions.
