KIV Energy from Waste (EfW)
Range: 2.5 - 25 MWth Thermal Capacity (< 65,000 tpa of MSW for single train)

In the past few years, KIV has undertaken and successfully demonstrated competence in EfW schemes, processing of industrial waste, which serves to demonstrate the effectiveness and efficiency of their technology.

This approach is completely in line with locally sustainable regional centres for waste processing that are being introduced in Europe and world-wide. By applying the preliminary treatment, the quantity of waste for incineration in such centres can be reduced by 40% or more.

Such cases, however, call for equipment of lower capacity than Mass Burn systems, and also feature numerous other advantages, such as:

  • reduced specific unit costs
  • optimum heat value generated from the waste used locally, i.e. district heating.
  • low operating and maintenance costs, while the process is fully automated
  • higher degree of acceptability in relation to the environment
  • compliance with the highest environmental standards, in particular those set by the European Union

KIV EfW systems can combust locally sourced untreated MSW and other wastes and turn it into useful energy (CHP with District Heating), thereby reducing ‘waste miles’, enabling Councils to achive LATS targets with the smallest 'Carbon Footprint'. An example of this approach has now been operational since November 2008 in Celje, Slovenia.

The contract was awarded to KIV following a European Union OJEC competitive tender process. 80% of the funding will come from the EU. As it is a showcase site, 70% of the funding came from the EU and the design had to achieve better than normal EU WID standards for emmissions.

The EfW plant is designed for 37,000 tpa capacity @ 7,800 hrs/annum (18MWth) and will gasify 29,600 Tonnes of Refuse Derived Fuel (RDF), mixed with 7,400 tonnes of Sewage Sludge Cake annually as fuel for the EfW plant. Power output will be 2.1MWe gross., plus 13MWth hot water @110°C into the district heating scheme.
