Large Scale Composting

[KaiB]

I am looking for ideas to handle large compost piles (manure, chips, clippings from the town and slaughter offal). As I see the operation, we are considering piles of say around 75 to 100CY which would need to be turned on a regular basis, perhaps with a long set of forks on the loader.

Another idea would be to cut trenches (like a silage trench) and backhoe into it...but these would have to be covered during wet months, I think.

Wide open for suggestions. Thanks.

You have the materials to follow a similar system to that known as Indore compost - named after a place in Inida where it was first developed. I suggest you read as much as you can about this before commencing operations. It will make good compost, and you can always jiggle the ratio of the different materials. Do a search for Sir Albert Howard, Indore and compost and you will get all you need. Probably best to download some of his books because I am sure you will conisder it time well spent. You might have to pay a small fee, but again I think that is worth the money. Howard's system was very labout intensive, but then he had cheap labour and there is no reason why it should not be mechanised. Turning and controlling moisture content are both extremely important, but easily managed. I cannot give you any US references of people who have used the system, but it was quite popular in the UK in the late 1940s/50s when bagged fertiliser was very scarce. Old McDonald.

It is interesting you bring this up about the UK in the 40's and 50's.

Sitting on my desk now is a book called 'The Waste Products of agriculture'

This was written by Sir Albert Howard and goes through his system in detail.

Some info can be found here

Back to your question

The way I have seem compost made in bulk in the UK is in big long rows of compost.

Like this


There are machines available that can turn the rown for you. I think these would be very expensive.

One idea I just had would be to make the rows about the same size as a rotovator and run this up and down the rows at low revs as not to make too much mess. This would fluff it up quite well.

I think that it would have to be covered when not being turned to speed up the process and to keep as much of the goodness as possible. You would need some sort of sheeting for this.

You might be able to make some sort of attatchment to unwind the sheeting over the rows like this



I dont know how well you would be able turn the heap over with a FEL if it was in one big pile.

How much space do you have to work in?

I do a couple of hundred yards of compost a year and make lots of loam mixes. I use a Allu bucket on my small excavator. Windrows are the way to go. You can just use the tracotr and bucket to turn the piles but the composting os more efficient if you chop the material periodically. Some folks use manure spreaders to make the windrows but you need a way to load the trailer.

This project ties into one of three feasibility studies we are performing at the moment (a meat processing facility, slaughterhouse and a mobile slaughter unit). We have long talked about large scale composting, but really given it no thought beyond normal farm manure and chip composting. We currently use the loaders to turn; ain't the best system.

Typical of this board are the responses above. Thanks, much to learn here. It may very well be that specialized equipment becomes necessary; at times though, group thought is a wonderful tool.

Land space is not an issue. I'm sure permitting and the rest will be, but without a concept and a study, nothing can happen.

Maybe I should read the referenced writings, but until now, everything that I have seen on the subject specifically says to keep meat scraps and offall out of your compost.

I don't think he means composting the animal offal, just the manure the animals produce

I did wander the same thing when I first read this thread though and in the first post it says clipping from the slaughterhouse?

 

[KaiB]

Yep...offal gets included in the mix.

Might try to find the book "The Complete Book of Composting by Rondale Books, Inc. Goes back to the 60's, out of print, sometime found in used book stores. It has a section on large scale and municipal composting.
