The amount of landfilled biodegradable waste decreased rapidly up to 2013, after which the reduction stopped. In 2016 and 2017, as a result of upgrading the infrastructure for mechanical biological treatment of waste before disposal, the amount decreased significantly again, and in 2018 it was almost zero. In the period 2016–2018 the amount was significantly lower than the target in 2020. The main measures to achieve this reduction are separate collection of waste and mechanical biological treatment of mixed municipal waste.
