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 is under construction and due for commissioning in July 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. For this level of funding, the design had to achieve
better than normal EU WID standards for
emmissions.
The EfW plant is designed for 45,000 tpa capacity @ 8,000 hrs/annum (18MWth)
and will combust 37,500 Tonnes of Municipal Sorted Waste,
mixed with 7,500 tonnes of Sewage Sludge Cake annually as fuel for the EfW
plant. Power output will be 2.4MWe net.,
plus hot water for approx. 500 dwellings.
