This is one of the nicer compost bins I've seen; neat and tidy, well
built and sturdy, and obviously well thought out. Not every compost bin
made from recycled materials is as attractive.
This one features
a replaceable front, with several boards that can be slotted into place
as the pile is filled, and removed when it's well rotted down and it's
time to aerate it - or use it on the garden.
Wire mesh allows
good air circulation, to prevent slowing of the decomposition. A top
can be put over this to keep the nutrients from leaching in high
rainfall areas, or to prevent excess water from snow getting into it.
Two or three bins like this give you adequate space to allow one batch of compost to thoroughly age.
Each
time you move it over in the course of aerating it with a pitchfork,
you fill up the adjacent bin. Then by the time you get to the third
bin, it's ready to use.
Pallets are such a useful score at the landfill - or anywhere that uses them for shipping their products. They are customized to the size specifically needed for whatever is being shipped, so they're not all the same size, making for a logistical nightmare.
Take the odd shaped ones off their hands.
Another design for compost bins is just squares made out of dimension lumber, usually 2x6, but you can use whatever you have available that is cheap.
Don't use treated lumber. By the time these rot, it will be years in the future. Just replace them as needed. build several square boxes, without a bottom.
Stack them to create the bin, fill with your favorite composting ingredients.
To turn, start taking off the layers of boxes, one at a time, placing the first one beside the existing bin.
Fork the compost into it until it's full.
Stack the next layer of wooden square.
Fill that from the bin, and so on, until you now have your compost completely turned, with the newest on the bottom, free to rot, and the oldest on the top of the pile.
Several stacks placed beside each other will be constantly turning, producing many cubic yards (or meters) of finished compost.
