[Community_garden] biosolids and municipal composts; credibility killer

The application of Class B biosolids is a contentious issue in many
parts of the country. I think the strong feelings that have surfaced
on this listserv show that many people are uncomfortable with the
idea, and when municipalities attempt to recycle it in rural
communities, the conversations there are often heated. In the
Northwest, where I live, the situation is much more friendly.
Whether that has to do with better products or a better effort to
educate the public and build grassroots support, I don't know.
Around 60% of the nation's biosolids are land-applied to farmland,
the rest is either land-filled or incinerated, or added to compost
for home use (this is a relatively small percentage).
I use biosolids, and I don't claim to be an organic gardener. But I
don't think the issue is black-and-white either, and I can see many
situations that would fall somewhere in the grey area.
And I don't think that biosolids should be included in the National
Standards. If there were more and more products like TAGRO on the
market, it may be a conversation worth having, but as of now, Class A
"Exceptional quality" biosolids are the exception, not the rule.
While the type of treatment plant that Tacoma uses is relatively
unique, there are many ways to achieve Class A status. Milorganite,
from Milwaukee, uses a drying process. I encourage everyone to
investigate the situation in your own city, but I would still
recommend that people at least take a look at biosoilds that have
been rated Class A.
