Hi, I would like to make compost at a local abattoir located near a cow feedlot. The idea will be to use 60% cow manure and 40% abattoir waste and mix that together with a compost turner. I will use the blood water dams at the Abattoir to moist the heaps when necessary. Any suggestions from your side please.
Kind regards

Welcome!

You can compost the manure by itself. In fact, its a good idea because the heat of the compost pile will kill the weed seeds that weren't digested by the cow. A lot of feed lots and dairy farms do compost their manure and sell it commercially.

But you can't add waste from the slaughter house. Composting animal by-products will slow down your composting and introduce diseases, not to mention attract flies and other carion insects. Meat products don't compost, they rot.

here is a resource, with resources, to check out...

Your location will have major implications--if in the USA, each state will have different regulations you must comply with as well as the federal regulations...
also, the kind of animal being killed (different rules for some), and the intended use of your compost--agriculture? food crops for humans, animals? (again, different rules for some)

I agree You can't use the abattoir waste to compost. The overall guideline for compost is you can use "anything that was a plant" but not proteins and fats from animals.

I guess, I'm just going to presume that the "abattoir located near a cow feedlot" is slaughtering fed cattle then,
and point out that the
"40% abattoir waste"
could actually refer to ideal composting material considering that the contents of the rumen (aka the paunch) is copious amounts of plant material and bacteria Thumbs up
Also, this is actually standard business in this arena where nothing is wasted!

You can use animal products in composting, but not too much. Animal products decompose the same way plant products do but slower. I don't hesitate to add bones and fats to my compost bins. Just not too much.

If you are getting above 5% animal waste, that is probably too much. It really isn't the best stuff to use. You really need a hot compost pile for it.
