Steam from household waste

As per 1 January 2003, the refinery operator H&R ChemPharm transferred the complete energy supply for the Salzbergen location to SRS EcoTherm GmbH, in which RWE Generation SE holds 90% and H&R GmbH & Co. KGaA itself holds 10% of the shares. 

At the heart of the Salzbergen industrial concept are the construction and operation of the thermal waste treatment plant, TAS for short. After a construction period of some 24 months, TAS has been generating 360,000 tonnes of steam from an annual 130,000 tonnes of municipal waste since September 2004. Travelling through an 800-m long pipeline, the steam reaches the industrial power plant – likewise passed to SRS EcoTherm – where it is initially used to produce electricity and then further utilised as process steam. 

Constantly under full load

Since the TAS is constantly operating under full load, it delivers some two thirds of the steam required by the location. Peak demand is covered by one heavy-oil-fired and one natural-gas-fired steam generator in the industrial power plant. The natural-gas-fired steam generator and the back-pressure extraction turbine were installed as part of a 13 million euro investment in the plant in the years 2015 to 2017.

Energy concept with measurable benefits 

For H&R ChemPharm, for the region and for the environment, the new energy concept brings measurable benefits: the refinery can cut its annual energy supply costs on the basis of current oil prices by some 40%. The fixed prices for steam deliveries over 20 years agreed with SRS EcoTherm also make production independent of price fluctuations on the oil market, thus offering a dependable calculation basis.

Modern technology minimises emissions

The Emsland district has secured – likewise for 20 years – low-cost removal of up to 70,000 tonnes of municipal waste annually. The remaining waste is delivered by several partners from the region. The emissions produced at the location from energy generation are reduced to a minimum thanks to the deployment of state-of-the-art combustion and flue gas scrubbing technology.
