In terms of number of facilities that can treat solid waste,
the results presented in Table 6 indicate their variation
over 2004–2012. The number of landfills and the Waste-to-
Energy facilities have decreased, while recycling facilities
have emerged, offering the perspective to treat waste, other
than by the classical disposal. Old landfills have been closed
down, either because they had reached the design capacity, or
because the legal requirements for the continuation of their
activities were not fulfilled anymore.
