STEP eyes adding SRF-fired plant in Harjavalta

In Finland, energy utility Suomen Teollisuuden Energiapalvelut - STEP Oy, a joint venture between municipal energy utility Pori Energia Oy and Veolia Nordic Ab is currently carrying out a study for the construction of a new solid recovered fuel (SRF) plant adjacent to its pellet-fired steam plant in Harjavalta Industrial Park, Harjavalta.

The design work is done in collaboration with Norilsk Nickel Harjavalta Oy (NNH). When completed, the plant will be the first energy plant in Harjavalta to be able to use non-recyclable waste fractions, such as SRF, for fuel.

Our goal is to reduce the environmental impact, save primary energy and at the same time support local cooperation and employment, said Antti Kokko, STEP’s Sales and Business Development Manager, STEP.

The SRF fraction, which is derived from non-recyclable commercial- and industrial wastes has up to now been transported long distances from Satakunta to landfills or waste-to-energy plants. The new CHP plant will reduce emissions from logistics and is also a cost-effective treatment solution for waste companies.

Our intention is to collect non-recyclable material from Satakunta and the surrounding area. The end-users of the energy produced by the plant are also operators in Satakunta, said Antti Kokko.

Replaces fossil fuels

When completed, the CHP plant will supplement the energy needs of companies in the Harjavalta Industrial Park area and displace virgin fuels. The largest user of energy-from-waste will be Norilsk Nickel Harjavalta.

We are constantly looking for ways to reduce our environmental impact, and most of the energy we use is renewable energy. The new plant will enable the complete abandonment of fossil fuels, says Joni Hautojärvi, CEO of Norilsk Nickel Harjavalta.

The new plant planned to be sited next to the current wood pellet fired steam plant will have a thermal capacity of about 30 MW.
