In Denmark, the national Danish producer responsibility register is run by the Danish Producer Responsibility System (DPA-System).
In addition to administering the producer responsibility register in Denmark, DPA-System works to design and administer a competition-neutral producer responsibility scheme for the relevant market players.
DPA-System is responsible for a number of administrative tasks that are linked to the rules of the environmental legislation on producer responsibility for electrical and electronic equipment, batteries and cars.
