Ever since I read @Colin's thread the other day about wood chips, I have been spending a lot of time trying to find a cost efficient, labor-saving way to shed down the voluminous amount of corrugated cardboard our home business creates.

So far I have read about ripping it, soaking it, layering it, cutting it with a table saw or band saw, using a lawn mower to chop it up, saw YouTube vids of weird looking homemade shredders that look like they might take your fingers off, more vids of home owners tenuously shredding it with their yard chippers, using a heavy duty office paper shredders just to have them burn out, and commercial or industrial cardboard shredders that would almost require a 2nd mortgage. None of these really seem practical.

Do any of you use corrugated cardboard in your compost pile the HAS been shredded down into small pieces, and how do you shred it? Or, any ideas I haven't mentioned above? Remember, I am talking a decent volume of cardboard. Thanks.

Thanks @alp. I want to avoid soaking then ripping by hand. I'm looking for a way to "automate" the process of make the large boxes into tinier pieces so it will break down much faster.

Add liquid detergent suggested here

How to Compost Cardboard Boxes It is critical that all cardboard to be composted is broken into small pieces. Large pieces will not decompose as quickly. Also, soaking the cardboard in water with a bit of liquid detergent will help to speed up the decomposition process. Begin your compost pile with a 4-inch layer of shredded corrugated cardboard with other high-carbon materials such as straw, old hay or dead leaves. Add a 4-inch layer of nitrogen rich materials on top of the cardboard such as fresh grass clippings, horse or cow manure, spoiled vegetables or fruit peels. Add a 2-inch layer of soil on top of this layer. Continue to layer in this fashion until the pile is approximately 4 cubic feet. It is imperative that the compost pile be kept about as moist as a sponge. Add more water or cardboard depending on how wet it feels. The cardboard will soak up any excess water. Turn the compost pile every five days with a pitchfork to speed up decomposition. In six to eight months, the compost will be ready to use in the garden. As you can see, learning how to compost cardboard is easy. In addition to being a great soil conditioner for plants in the garden, you’ll find that using cardboard in compost will help keep unwanted trash from piling up.

Thanks, @alp. I read this article before. As I said, I am not really interested in soaking the cardboard and then manually shredding it. I am looking to automate the process.

This morning I purchased a Royal 1620MX - Cross Cut Shredder (16 sheet) after watching a YouTube vid about it...actually the vid was on an earlier model, but this is it's replacement. It is commercial grade and all gears are steel instead of plastic. It was $99.99. I'll post back on how it does.

Here's the YouTube Vid

Well, my new shredder arrived this morning, so I decided to unbox it and give it a go. It shreds my corrugated boxes with no problem at all! ...just like the video above. I already have filled big plastic bag. Yeah...now I will have plenty of small cardboard pieces for my vermicomposter and a whole lot more for my outside composter.

Sure will @MaryMary. I wound up shredding a garbage bag of cardboard today, and it didn't jam or overheat at all, but I am not going to push it. The steel gears and cutting blades are guaranteed for 5 years, but that is only if you are shedding no more than 16 sheets of paper at a time, cd's, etc...but it is sold as "commercial grade", so even if it lasts a couple of years, I'll get a ton of good carbon for my compost.

Well done! A good find. Make sure you keep the receipt and take a photo of it just in case everything fades. At least, it's not one of those big industrial steel units I saw clanking on youtube!.
