The EU Directives on WEEE, batteries and packaging require member states to transpose the Directives into their country’s law, and have no effect without this . Only the national regulation or law would apply.
In Portugal, the EU Directive on WEEE (Directive 2012/19/EU of the European Parliament and of the Council of 4 July 2012 on waste electrical and electronic equipment) was implemented through Decree-Law No 67/2014 from 7 May 2014. This was later superseded by Decree-Law No 152-D/2017, which unified the regime for managing specific waste streams (EEE, packaging and packaging waste, batteries and accumulators and their waste etc) subject to the principle of extended producer responsibility.
