Here's my latest stickyminds article. It's about turning waste into by-products.
Summary: Sometimes we don't see the forest for the trees—or, as Clarke Ching writes in this article, the crabmeat for the crabs. Are there by-products of the work you do that are currently considered waste, but which might actually be useful? Clarke offers some examples of by-products found in a number of organizations and invites you to reconsider the by-products in your own company.
I quite like this one because I found it easier to write than most. I got the idea for the article while reading the book Rework. They have a page or two about by-products which sparked all sorts of interesting thoughts in my head. I hope maybe this article does the same for you.
