Citations were provided on the original page for the entire list. When this list was moved and spun off to this page, none of my citations were moved along with it. Whilst the creation of its own page is great, we have lost all the references that went with it. Lostinlodos (talk) 14:48, 8 February 2008 (UTC)
I found a list of materials and codes on a euro-lex.europa.eu page. Unfortunately it is not available in english. It is taken from: Official Journal L 050 , 20/02/1997 P. 0028 - 0031 Zeptomoon (talk) 15:38, 28 July 2008 (UTC)
There are no International Universal Recycling Codes
Material Identification is country specific —Preceding unsigned comment added by 184.108.40.206 (talk) 19:43, 21 June 2010 (UTC)
A brief bit of investigating seems to show the numeric codes appearing in both the Ordinance on the Avoidance and Recovery of Packaging Waste (12 June 1991) (Germany) and Law 11/1997 on Packaging and Packaging Waste ("LERE") (24 April 1997) (Spain); these in turn appear to be derived from somewhere in Directive 94/62/EC (amended by Directive 2004/12/EC) on packaging and packaging waste. There's a lot of text there, though, and I didn't try to find the exact source. In short, I suspect that the numeric codes are EU-specific, and that there is no standard combining them with the universal recycling symbol in the fashion that this article suggests. So this article may well be original research. — Hex(❝?!❞) 17:07, 22 June 2010 (UTC)
