Waste incineration plant in Kraków will recover energy from household and industrial trash

The construction of a waste incineration plant in Kraków will help the city to dispose of waste to high environmental standards and will also create a new source of electricity and heat.

The project is the missing infrastructure link in the city’s waste disposal system and will allow the southern Polish city to dispose of municipal waste fully in line with national and European Union legislation.

Energy recovery to power city utilities

The plant has been designed to process and recover energy from the waste of around 750 000 city residents, and will consist of two independent processing lines, each with a capacity of 14 tonnes per hour. It is intended that the plant will ultimately be connected to, and provide energy to, Kraków’s heating, electricity, sewerage and water supply systems.

Vehicles bringing waste to and from the plant will be weighed on automatic scales, equipped with specialised instrumentation and software, which will keep full records of the chemical composition of the waste. Fly ash and residues from the flue gas purification process will be chemically stabilised and solidified prior to landfill disposal or their use for some other purpose.

Construction materials to be recovered from the incineration process

Around 80 % of the entire stream of slag and bottom ashes will be used as construction materials, such as road base material.

It is likely that around 13 % of the processed waste will be categorised as unfit for recycling and will be disposed of in a landfill site. Energy from the incinerated waste will be recovered from a boiler connected to an oven and a heat exchanger connected to a turbine will allow for the cogeneration of both electricity and heat. Efficient treatment will ensure that the system meets rigorous emissions standards.

It is anticipated that the total amount of waste to be processed by the new plant in 2015, the first full year of operation, will be around 221 462 tonnes. Once the incineration plant is in operation it is expected to directly create 65 jobs.
