[greenyes] Info. Request, Blueprint recycling

[Minimushomines@no.address]

    Can anyone direct me to information on the recycling of blueprints? There 
are a number of architectural blueprint users in my community that are 
interested in knowing what their options are for recycling this material but they 
think the materials that makeup the blueprints contain toxics. Thanks in advance 
for any info.
