This type of waste has increased: in Spain due to the replenishment of the Cofrentes nuclear plant and the decommissioning of the Escombreras, Castellón and Santurce thermal plants; in the United States due to the dismantling of offices, the remodelling of certain buildings, and the legal obligation to clean contaminated soil; in Brazil due to the inclusion of the Elektro subsidiary within the IBERDROLA Group, which has its own waste management programme.
