Summary

The first pilot Joint Implementation (JI) project in Poland, at the City Greenery Unit in Jelenia Góra, replaced two low-efficient coal-fired boilers with a high efficient boiler burning wood chips obtained as waste from the management of the city green areas. It has brought many environmental benefits such as reduction of GHG emissions as a result of fuel conversion (coal to biomass), avoidance of methane emissions from wood decay at the landfill, reductions of emissions resulted from avoided transportation of coal and waste wood. The project started in 1998 and was commissioned in 2000. Since then monitoring for JI purposes has been continued.

Results

Before modernisation the heating system for greenhouses in Jelenia Góra had the following parameters:

• Total surplus of 2540 m³ waste wood in the city;
• At least 700 m³ of wood waste deposited in dump;
• 2 coal fired boilers, 256 kW each used;
• Yearly coal consumption - 220 tonnes.

After modernisation the annual quantity of wood used for heating purposes (not dumped) - 388 t. (1100 m³, moisture content 55%), 1 automatic wood chips fired boiler, 350 kW and no coal consumption.

The following benefits were brought by the installation of the biomass technology:

• Savings of 220 tones of coal by its replacement with biomass;
• Abandonment of the storage of 385 tones of waste wood at the landfill, and thus, reduction of the greenhouse gases emission resulting from the decay of organic material;
• Decrease of the fees for using the environment;
• It was estimated that throughout the period of project lasting (15 years), total reduction of carbon dioxide emission would be 21 thousand tones of CO₂ equivalent.

Project lifetime: 15 years
