Increase of 8.2% in Solid Waste in 2012
In 2012, the total amount of waste treated in Malta amounted to 1,988 thousand tonnes, up by 83.9% over 2011. This mainly resulted 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% and 21.2% respectively.
Table 2 shows that the amount of waste managed in the Għallis Landfill went up by 7.2% over 2011. Whereas municipal waste declined by 2.7%, secondary waste arising from wastewater treatment plants and waste sorting facilities increased by 25,772 tonnes, or 41.8%.
The management of inert mineral waste advanced by 125.0% 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%. Table 4 shows that the bulk of input into the Sant’Antnin Plant originates from municipal sources. In 2012, municipal waste made up 94.4% of the total waste input into the plant.

Waste originating from public and private slaughterhouses and by-products of animal rearing was predominant, accounting for 90.3% of the total inputs into this facility.
The treatment of waste in private pre-treatment facilities amounted to 66,047 tonnes, up from the 61,643 in 2011, primarily due to an increase in construction and demolition waste (+131.4%).
In 2012, waste collected from bring-in sites dropped by 30.4% as a result of sharp declines in the collection of paper and cardboard and glass, by 38.2% and 27.8% respectively.
