The IBI (International Biochar Initiative) just posted a draft of the
"Guidelines for a Safe Biochar Industry" document. This document, as
some of you may know, is a result of the Characterization Work Group's
discussions at the U.S. 2009 regional conference.

Since biochar quality is extremely variable, in my opinion it is
incredibly reassuring to know that in the future there will be
standards that biochar producers can choose to use as guidelines. As
well as labels that tell the consumer if the product has met these
standards. This is a much-needed system that ensures quality,
although much research is needed to characterize "high-quality
biochar" (i.e. slow/low-temp. pyrolysis, etc.)
I would love to see the Characterization Work Group take this a step
further and create Sustainability Standards as well, where biochar
products can be labeled as "sustainably produced" (i.e. using only
waste feedstocks and not feedstocks grown for the purpose of biochar
production...etc.).
