The waste-to-energy CHP plant

The waste-to-energy CHP plant

The waste-to-energy CHP plant in Nykøbing Falster is REFA's biggest facility, has 26 employees and  generates an annual turnover of approximately DKK 130 million.

The waste-to-energy CHP plant has been converting household waste and other combustible waste into district heat since 1983 . In 1999, a third incineration line was added to the two existing incinerators. In addition to generating heat, the third line also generates electricity.

REFA processes waste collected from 54,000 households, 11,000 holiday homes and 4,000 businesses in Lolland–Falster. Apart from household waste, REFA also incinerates small and large pieces of combustible waste from the recycling centres. In addition, REFA receives payment for importing and incinerating industrial waste from Germany and the UK.

110,000 tonnes a year
The waste-to-energy CHP plant processes 110,000 tonnes of waste a year. 60,000 tonnes of household waste and 50,000 tonnes of other combustible waste are converted into:

  • 190,000 MWh district heat
  • 50,000 MWh electricity
  • 20,000 MWh are released into the air

The heat is sold to Guldborgsund Utility Company and provides heat for 10,000 households. The electricity is sold on the open electricity market. The electricity generated at the plant is equivalent to the consumption of 10,000 households. The three incineration lines incinerate 18 tonnes of waste per hour.

Cinders
One tonne of incinerated waste yields 216 kg of cinders and 30 kg of ashes. The cinders are sifted and most are used underneath asphalt for laying new roads.

De-heating
Surplus heat arises because, by law, household waste must be incinerated right away; in summer, this generates more heat that can be used by Guldborgsund Utility Company and the heat cannot be stored.

All of REFA's heating plants are monitored from the control room of the waste-to-energy CHP plant in Nykøbing Falster. The control room is staffed 24/7 all year round.

Cleaning of exhaust gases
Both internal and external controls continuously monitor the exhaust gases from the plant's three incinerators. The exhaust gas is cleaned through tightly-meshed bag filters, and acids are neutralised with lime.
