The three inter-communal syndicates operate, respectively, two controlled landfills12 and an incineration plant.13 The incinerator handles around 135 000 tonnes of waste a year, 10% of it from other inter-communal syndicates. Thermal treatment costs around EUR 0.10/kg of waste.14 The incinerator generates 5 700 tonnes of hazardous waste every year, as well as 29 000 tonnes of slag, most of this waste is exported to Germany, including the slag which, until June 2008, was recovered in Luxembourg. The remaining quantities are such that domestic facilities are less justified than in the past. Non-household waste for disposal is exported to specialised facilities in neighbouring countries, primarily in Germany.
