Hi Roger -

Thanks for the references to the web pages on adding gypsum to
composting operations. . I've downloaded their material and am now
reading through it to see what I can find.

You asked me to send to the lists any information I find on ways to
recycle drywall.

Actually, I've been compiling this information for a couple of years
and have an 80+ page bibliography that I would be glad to send to
anyone at no cost. Unfortunately, it's not organized in any
particular order, so items are listed as I came across them. But it
hopefully will still be of help to people interested in the subject.

Let me first add the new items that I've found here and then I will
email you a copy.

Thanks again,

John
