Good Practice


The „energy bridge“ brings steam across the Rhine. © Andreas Götz

Since mid-2009 a number of industrial enterprises in Liechtenstein, the two largest energy consumers of the country among them, are supplied with process steam from a waste incineration plant in the Swiss town of Buchs, substituting oil or natural gas with steam.

Construction of a steam conduit over the Rhine - Substitution of oil or natural gas with steam. Contribution to the struggle against climate change.


About 125 tonnes of steam are supplied per year. This is equivalent to about 85'000 MWh of heating energy.


Substitution of oil and natural gas with steam - significant CO2 reduction. Figures differ by source: 1) About 10 million litres of fuel oil were saved per year. CO2 reduction: 20'000 tonnes per year (Klimastiftung Liechtenstein) 2) About 9 million cu.m. of natural gas were saved per year. CO2 reduction about 13,000 tonnes per year. The substitution accounts for about one-third of Liechtenstein's Kyoto objective for CO2 reduction. (The use of process heat however also reduces power generation by the Buchs waste incineration plant) (Verein für Abfallentsorgung)

II Assessment criteria

Energy cost savings

Public relations impact and awareness-raising: Medium

Local and regional media response. Part of the steam conduit is highly visible: it crosses the Rhine with a bridge for pedestrians and cyclists.

Transferability: Very high

Technology can be applied to other waste incineration plants (this is quite common).

Cross sectoral and integrative approach: Medium

The steam supply can be seen as part of the environmental/sustainability policy of the firms involved.

Good governance: Medium

Entrepreneurial initiative in consultation with the municipalities and regions.
