The total amount of waste treated in Malta in 2012 amounted to 1,988 tonnes,
up by 83.9 per cent over 2011.
The National Statistics Office said this resulted mainly from an increase in inert mineral waste which more than doubled. Furthermore, the treatment of municipal waste and other waste streams increased by 1.2 per cent and 21.2 per cent respectively.
The amount of waste managed in the Għallis Landfill went up by 7.2 percent over 2011. Whereas municipal waste declined by 2.7 per cent, secondary waste arising from wastewater treatment plants and waste sorting facilities increased by 25,772 tonnes, or 41.8 per cent.
The management of inert mineral waste advanced by 125.0 per cent over 2011, mainly due to a sharp increase in the management of mineral waste from dredging. On the other hand, non-hazardous mineral waste managed in quarry
sites remained stable.
In 2012, the input of waste into the Sant’Antnin Waste Treatment Plant, managed by WasteServ, went up by 10.6 per cent. The bulk of input into the

In 2012, waste collected from bring-in sites dropped by 30.4 per cent as a result of sharp declines in the collection of paper and cardboard and glass, by 38.2 per cent and 27.8 per cent respectively.
