Rooster,  I'm more concerned about what humans ingest (medication, drugs) and garbage disposal products (with trace pesticides) that will pass through digesting and composting without breaking down.  At one time in CA it was permitted for feed crops, only, i. e. alfalfa, oat hay, feed grass, etc.)  I don't know what the status is at this time.  Though in 3rd world countries it is still used.  Well, making my own compost just feels, well, more reassuring.  Razz

I'd always rather make my own as well. But I like to question what is just generally believed or preached to be bad. I've never seen any definitive proof that the use of such is causing a problem, or if it's just guessing. If trace elements are found in the growing medium, are they or have they been rendered inert? Are they taken up by plants and animals and passed on? If passed on, are they inert at that point?

And for fairness a Canadian study saying not a problem With the giant caveat called out about Canadian law being 1 year between application of biosolid and harvest of plant for consumption.  https://www.ncbi.nlm.nih.gov/pubmed/22687432

Is there any real science behind the claims that bio composts are bad? Or is it all just interwebs folklore? I know for a fact countless crops that feed thousands of people, are fertilized with bio composts. I've used bio composts with results when I've had to purchase compost. Is it just a personal choice to not use such? Fear? I like to base my decisions on fact. That tends to be better bet (at least for me) than following the current trends or interweb, garden lore. Many read things over and over again and consider it proof and or fact.
I'm not saying bio's are good. I'd just like to see adequate science that proves they are bad.


 I saw a good programme about China a few months ago .

China have some rather large cities which all use a combination humanure & vegetable waste to fill their city farms growing beds . The workers usually work bare footed in it  often up to their calves in a light fluffy growing medium .   Annually we are talking of millions of tons of harvested crops taken from the beds .

There are no admitted pathogens in the beds or other nasties that are harmful to humans or animals apparently.
 All bed filling materials & harvested crops are tested daily ..in some cases hourly to ensure th health & quality of th product .

 They grow some fantastic crops too , We in the western world may do well to take on their ideas at an industrial scale close to all our cities .
