Sara June 2 bay pallet system

A two-bay compost system using pallets

This compost was to tend to the waste of a 4 person household in Arcata, California. The house had a garden beginning and produced a fair amount of green-waste. My goal was to have a flowing system that would produce finished compost over time but one that needed little turning. I also needed something I could deconstruct easily if I left the house. It was in budget and desire to take useable material out of the waste stream. therefore I choose pallets for the main material. I made the system quick as the COVID-19 pandemic set in, without altering the pallets much. After this, I was able to test the design and see what types of needs the house had and how accessing the bays went. Redesigning it gave a whole new design fitting the house's needs and size very well! This is a project anyone can do with a little tool borrowing.

Here is how I revamped the oversized pallet system to fit the needs of my household.

How to Build[edit | edit source]

Start with a simple design in mind. Map out the space and what materials you have. You will want to choose a plot that is both accessible to you in a moment between dinner, yet out of the way of things like any important plants. It is nice to have your compost receive sun and water. Preferably not under evergreen trees, for do not easily decompose.

Place four pallets around a middle divider. Using steel wire, wrap pallets together. Boom compost! Super simple and functional. From a design standpoint, however, not meeting the criteria.

After deconstructing the pallets, prepare the space by measuring a layout (3' by 3'). Then, clear the space using a metal rake. Finally, using a hoe, scrap 2 inches into the ground to sit pallets into the ground. This area was already quite soft due to the compost being there before.

Using chalk, draw a straight line that the power saw will go over. Be on the lookout for any old embedded nails!.

Using the other side of the pallets old wood, fill in spaces by hammering in pieces of wood in gaps. This will help keep contents in place, especially during the heavy rain season.

Place pallets together and bind using steel wire. Bring dirt around the bottom to help keep pallets upright and in place.

This post can be made with sturdy hardwood sticks, the sides of pallets, or a metal pole. Dig the stick into the ground and fill in with soil around it. It should be very snug in the ground. You may want to use a hammer to tamp it down (not for metal pole).

Finally, slide in two large boards to the front to keep content in. Here you have your finished 2-bay compost system! Fun sized and ready to add to materials!

Troubleshooting[edit | edit source]

From the first design to the second, these were some adjustments I made. I also made a flow chat to help figure out what is wrong with your compost and how to fix it.

Lessons learned[edit | edit source]

Building a compost system on a larger scale is very obtainable. Even this rustic one has a nice aesthetic and functions well. Getting to learn from what the inside is doing is the real challenge. Overall, this compost operated as both a windrow pile that could simply sit and decompose over less than a season's time. Or it can be turned to speed up the process. Harvesting finished compost felt great! And the plants enjoyed it!
