Woody biomass-fuelled furnace:
Did you know?
At present there are about 2,000 biomass-fuelled power plants operating in the world, half of them in Europe.
The recultivation of Tüskésrét
In the landfill of Tüskésrét almost 30 million tons of slurry consisting of slag from the bottom of the boilers and flue gas fly ash separated by the electro filters was deposited in cells during the roughly 50-year long coal firing period. Most of the cells have already undergone rehabilitation but in case of about 51 hectare cell it is still ahead of us, although the preparatory works have already started.
Pannon Hőerőmű Zrt. ceased to use the slurry cells after the fuel change of 2005. After conversion to biomass and natural gas combustion the cells were not needed for depositing the by-products of coal firing any more. In the first stage, the power plant covered the slurry cells with ten centimetre deep topsoil, with this however rehabilitation was not completed, since the environmental authority required one metre deep topsoil.
As the area is owned partly by the power plant, partly by the Municipality of Pécs, a written agreement describes the rehabilitation tasks to be performed. Under the agreement the 51 hectare slurry cell covered partially, i.e. with thinner layer than required, shall be rehabilitated with topsoil extracted from the enlargement of the existing groundwater lake.
The preparatory works of the project have been performed during the past years. In so doing, Pannon Hőerőmű Zrt. has the rehabilitation and lake enlargement licensing and implementation plans made, while the Municipality has acquired former private lands. Before the works can be started the Municipality must yet agree with the state about the only state-owned immovable property’s use and ownership and the Environmental Inspectorate’s water rights implementation permit for the lake enlargement must be issued, which procedure has already initiated by Pannon Hőerőmű Zrt.
Based on the above, the lake enlargement and land rehabilitation works, following the public procurement procedure, are expected to start early next year. In the course of the project 850 thousand cubic meter earth will be moved, which will increase the barely five-hectare water surface of the lake more than four times. This will make it possible for the municipality of Pécs to establish a city park for recreational purposes with a more than twenty-hectare water surface next to the city centre.
There are European Union resources available for the creation of the recreation park. In the coordination of the South-Transdanubian Environment Protection and Water Management Directorate, this was the only Hungarian project that has successfully submitted a tender for the support of the SUFALNET4EU the main purpose of which program is to establish the context for the sustainable re-development of the closed landfills. In April and in September the body assessing the applications visited the site to be re-developed. The final decision about the support is expected to be made by the end of the year.
The land rehabilitation to be financed by Pannon Hőerőmű Zrt. committed to environmental protection may create new and exceptional development opportunities. In the city centre, only at a few hundred meter distance from Siklósi Road, a vast green area will open, where a recreation park can be established to provide entertainment facilities for water lovers and hikers.
