[USCC] Composting animal blood

[Jean Bonhotal]

CWMI is currently writing a fact sheet on composting liquids in 
general, there are pretty simple methods to deal with liquids if that 
is the best option. It will address liquid and coagulated blood, 
biodiesel residuals, liquid manure, non food grade liquid dairy 
products I would be glad to talk with anyone about it, fact sheet 
should be out for review Jan. or Feb. If there are interested 
reviewers out there let me know.

>concerns about the growth of pathogens, though good composting
>techniques should put this in check.
>The proposal is for animal blood from a slaughterhouse to be composted
>with woodchips, animal manure, paunch manure and cotton burrs.
>
>Should there be decontamination of windrow turning equipment?
>Should this be done on an impermeable pad?
>How often should this compost be turned?
>Any special requirements for pathogen testing?
>Extra control for vectors such as flies?
>'Special' odor problems?
>How do you add blood to a woodchip pile and not have some of it 'run'
>right through?
>
>I know that's quite a list of questions, but if you know of any other
>concerns I would greatly appreciate the input!

>Thanks in advance for any information.
