In 2017 the amount of collected municipal waste was 29.6 million tons, i.e. 524 thousand tons less than in 2016. Percapita production was 488.7 kg (-1.6% to 2016). The landfilled amount was 23.4%, therefore a reduction to 2016. In compliance with the Directive 1999/31/EC, and in order to safeguard environment and human health the amount of landfilled waste should go on decreasing. Separate collection accounted for 55.5% of municipal waste and confirmed the increasing trend of the last years, though the goal of 65% established for 2012 was still far.
