Coompost Bins
I am reading Storey Publication No. A-139 on composters. It
states you can use treated lumber for composting bins. Knowing you can't use it for raised beds, I'd like to know why it can be used for one thing and not the other. Is it because compost is a "second stage" material, ready to break down again in the soil and soil for raised beds is not? |

PT wood is just plain nasty to work with. And there's certainly
*some* arsenic that would leach into your compost. How much? Who knows without a quantitative lab test? But by using other materials (wire fencing, plastic, etc) your compost will certainly have LESS arsenic in it. Regular lumber would be fine, although it may only last a few years unless you used cypress, cedar, white oak, or redwood.

Recycled pallets are a good, cheap source of untreated lumber.
Tie three together and you have a bin. Phisherman wrote: PT wood is just plain nasty to work with. And there's certainly *some* arsenic that would leach into your compost. How much?

A compost bin made of PT wood would enhance the leaching of the cca into the compost via all the bacterial and fungal activity. Bad choice |

Coompost Bins
Beth,
I saw a similar three-bin system on Gardening by the Yard on HGTV. They suggest treated lumber due to the tendency for wood to rot when in contact with the ground. I built the 3-bin system but used untreated wood to ensure no arsenic would leach into my compost. We have a commercial 3-bin system at the Arboretum that is treated wood and the compost has been fine, but I didn't want to chance it. I'll replace the wood as it rots (or let it compost - lol). An easy alternative is to cut 3' high fence wire in 10' strips, then use a 4' piece of 1/2" PVC pipe to thread through the fencing at the ends to hold it in a loop. You can simply remove the pipe and move the fence to turn the compost. Quick and easy. A three-bin system can be made from 10 used pallets, which are often free at building supply outlets and other places. Simply tie them with garden twine into squares by standing them on edge. Cut the string to move the material from bin to bin. You can buy a pretty good commercial compost bin like the Seattle bin for about the cost of the lumber to build a 3-bin system, by the way (about $80). Our Seattle bin at the local Arboretum was at 160 degrees after three days. We had to remove the lid to cool it a bit. Good luck and enjoy composting.
