In this case, the packing company pays an amount for the quantity in weight of the packaging placed on the domestic market to the managing company of this Integrated Management System. This money serves to finance the selective waste collection, and the transport and selection of the different materials.The SIG is the alternative most widely used by the packers of products intended for household consumption.

Currently from the Agència de Residus de Catalunya four integrated management system management companies have been authorised, depending on the packaged products, which are the following:

In this case, the packager establishes a system to physically recover their packaging. To guarantee this recovery, the packager collects an amount by way of deposit from the customer, and this amount is returned when the packaging is effectively returned. This process occurs throughout the distribution and commercialisation chain to the end consumer.

Packaging received in an SDDR is identified with a symbol established in the Order of 27th April 1998 regulating the operation of this system.
