Microbrewery recycle, renew, reuse challenges are often harder due to the lack of economy of scale. At Quay Street Brewing Company (
http://www.quaybrewing.com a microbrewery & restaurant in Michigan), used grain management includes: donating left-over grain to local farmers as a feed supplement, the formulation/production of a high fiber treat/snack for dogs "Brewer Bones." The grain has also been used in soil treatments and composting. All great ways to change "waste" to "use" and avoid senseless expansion of garbage/land-fills.
