It seemd to me that RRF could usefully build a resource of copyright-free clip-art and images associated with waste. Here is one resource, if you have or know of others please let me know - we will of course share the results.

Our colleagues in New South Wales, Australia - Sustainability Programs Division Department of Environment and Conservation (formerly known as Resource NSW) - have a useful resource on their website: free art-work for recycling bins:

General Recycling Symbols Garbage Paper Glass Cans Liquid Paperboard Plastics Mixed Recyclables Compostables Strip Stickers Construction & Demolition Blank Signs

The signs may be downloaded and used, copyright free, for any reasonable purpose, from:

http://www.resource.nsw.gov.au/index-RNSW.htm

Simply click on the appropriate format and the original EPS, JPG or TIFF image file will be downloaded to your computer.
