Since 2007, there have been several government resolutions in Colombia leading to the obligation of manufacturers and importers of certain products (pesticides, medicines, batteries and accumulators, computers and printers, used tires and used lead-acid batteries) to design, finance, and implement programs for the selective return of wastes. This obligation has been imposed on producers and importers by the national government in the context of international environmental law regarding extended producer responsibility. It is hoped that the country will also implement voluntary and regulated post-consumer programs for electrical and electronic devices, plastics, and used lubricants. This text contains a comparative analysis of existing regulations, proposed regulatory changes in response to what has been learned from the application of existing post-consumption regulations, and suggestions for regulatory reform in keeping with current development in the international literature.
