Topic of the practice

Renewable energy. Combined heat and power production using household waste, peat and biofuels.

Good Practice Information

In the Ljungby Combined Heat and Power (CHP) plant there are two boilers, one for waste and one for peat and biofuels, with a total power of 30MW heat and 4MW electricity. For the electricity production there are two turbines. The boilers as well as the turbines can be run together or separately. The fuel mix consists of 65% waste, 24% peat, 8% wood chips and 3% oil and LPG. The waste consists of approximately 85% renewable material. In Sweden it is illegal to dump combustible waste on landfill. Ljungby Energi AB gets paid to take care of the waste, i.e. a positive fuel cost. The exhaust is treated to remove all contaminants and is well ahead of EU limitations on exhaust. The district heating network supplies heat to 80% of the 14,000 inhabitants in Ljungby and also to many industries.

Evidence of success

The CHP plant has good reliability in operation, good emission values – well below the EU limitations, waste is converted to useful energy. It is possible to take care of combustible waste and at the same time produce heat and power. Waste has a positive fuel cost.
