Packaging symbols

Packaging or products bearing these symbols remind us that they can be or have been recycled, and provide us with information as diverse as the type of material from which they are made, or the specific place where they should be deposited for convenient recycling. Thanks to this, consumers can become aware of the importance of recycling, a habit that helps to save energy, raw materials and in the waste collection and disposal process.

A Green Dot packaging means that your responsible company complies with Law 11/97 on Packaging and Packaging Waste. In other words, it is guaranteed that when it becomes waste, this packaging will be recycled and recovered, normally through the Integrated Packaging Waste Management System (SIG), managed by Ecoembes. Specifically, the containers that can carry this symbol are plastic, metal containers and Brik type containers; cardboard and paper; and glass.

The Green Dot symbol was created in 1991 by the private German non-profit company Duales System Deutschland AG. It was subsequently adopted by other European Union countries, and in 1994 the Member States decided to make it the mark for the European Packaging and Packaging Waste Directive.
