The PITCH-IN symbol



This symbol of a stylized person cleaning up the environment was adopted in 1976 as stated on the website of PITCH-IN Canada (www.pitch-in.ca) which is associated Clean World  International, a non-profit organization with worldwide membership. Unlike the other recycling symbols, this symbol is not primarily used to identify materials for separation (though a variant of this design occurs as part of the glass-recycling symbol) but it is widely used in the context of public education and outreach for anti-littering efforts (with or  without a recycling component). The use of this symbol is not limited to one country and therefore makes it a good candidate for inclusion in an international standard.

The Green Dot



The Green Dot is a symbol first introduced in 1994 by Duales System Deutschland,
which implemented a novel financing system for recovering packaging by licensing the
green dot to its manufacturers and setting up a system to collect used packaging bearing this symbol from the end-user. Since 1994 this system has been adopted in eleven European countries altogether. See www.greendot.ie. The widespread and transnational use of this symbol would appear to make it a good candidate for encoding in an International Standard. However, use of this symbol requires licensing contract between manufacturer and a partner company in the PRO-Europe ssociation. Therefore the green dot could not be considered for encoding without a request from the trademark owners. In this regard it is different from the other recycling symbols.
