Main idea of the project
• Creating an integral system of renewable energy
production comprising 2 main elements:
– Pellets production line
(production capacity: 1 t/h)
– Plantation of an energy plant – a hollyhock
species Sida hermaphrodita as a source of
biomass for pellets production
• within the industrial area

Location of the project
• South-western Poland
• community Rudna with a deteriorating
agriculture and industrial areas
• High unemployment rate: ca. 20%
• Protective area around copper works and
the flotation waste reservoir (ca. 14 km2)

Plantation of Sida hermaphrodita (1)
• size: 300 ha (ca. 25.000 plants per ha)
• very high annual yields
(up to > 20 t dry biomass/ha)
• low climate and soil requirements
• suitable for industrial land
• easy in cultivation, traditional methods
• low moisture content in the biomass (25%)
• good parameters as a fuel (comparable with
wood)

Pelleting plant (1)
• Placed in the vicinity of the plantation
within the existing infrastructure
• Production capacity: 1 t/h
• Expected annual output: 6000 t pellets
• Energy consumption: 600 MWh/year
• Energy output from the produced pellets
– ca. 30.000 MWh/year (=108.000 GJ/year)

Pelleting plant (2)
• Consists of 3 main elements:
– a dryer
– hammer mill
– pellet mill
• Raw material supply for pellets production:
– In the initial stage: waste wood from the wood
industry
– In the long run (after 2-3 years` operation): biomass
of Sida hermaphrodita

Prospects for the future
• EU target: 12% energy from RES by 2010
• Polish Strategy for Development of
Renewable Energy Sources sets following
targets:
– 7,5% energy from RES by 2010
– 14% energy from RES by 2020
• Biomass = over 90% RES in Poland

Risks
• Grant for the project not awarded
RE: search for additional investors
• Incompetitiveness of bio-fuel on the Polish
market
RE: focus on foreign markets, search for pellets consumers
• Lower than expected productivity of Sida
hermaphrodita plantation
RE: supplementing Sida biomass with waste wood or other
energy plants

Future developments (1)
• Establishing a network of local pelleting plants
(1-2 t/h) combined with a system of Sida
hermaphrodita plantations
• Pellets for the individual use (family houses)
• Segi-KGHM partnership as a pilot project
– model system for the production of renewable energy
from the biomass
• Searching for investors for projects based on a
similar scenario

Future developments (2)
• In the long run: developing pellet market
• Modernisation of small district heating systems
(power of several MW) as well as heating plants
(200 kW - 1 MW) in industrial plants and public
utilities (schools, hospitals etc.)
• Package offer: heating plant for pellets +
continuous supply of fuel
• Looking for partners offering technologies of
pellets’ combustion to apply in such heating plants
