Materials Needed

To build your own cinder block compost bin, you will need the following materials:

Cinder Blocks

Cinder blocks can be purchased from any hardware or home improvement store. You will need around 15-20 blocks for a small compost bin, or up to 50 for a larger one.

Gloves and Mask

It is important to wear gloves and a mask when building your compost bin to protect your hands and lungs from dust and debris.

Heavy-Duty Trash Bags

These are used to line the bottom of your compost bin to prevent soil and other materials from falling out.

Shovel

A shovel will be necessary to level the ground and dig a small trench for your compost bin.

Composter Starter Materials

You will need some starter materials to kickstart the composting process, such as leaves, grass clippings, and vegetable scraps.

Construction Steps

Here are eight simple steps to follow when building your own cinder block compost bin:

Step 1: Select the Site for Your Compost Bin

Choose a level area of your garden that is not in direct sunlight.

Step 2: Level the Ground

Use a shovel to remove any weeds or grass from the area, and level the ground.

Step 3: Lay Out the First Layer of Cinder Blocks

Place six cinder blocks in a rectangle shape, leaving a gap in the middle for a doorway.

Step 4: Build the Second Layer of Cinder Blocks

Repeat step three, but this time place the cinder blocks on top of the first layer, staggering them so that you create corners.

Step 5: Prepare for the Third Layer of Cinder Blocks and Place Composter Starter Materials

Place a heavy-duty trash bag on top of the second layer of cinder blocks, and add your composter starter materials.

Step 6: Continue Building Your Cinder Block Compost Bin

Repeat steps three to five until your compost bin reaches your desired height.

Step 7: Fill Your Compost Bin with Composter Starter Materials

Add leaves, grass clippings, and vegetable scraps to your compost bin to start the composting process.

Step 8: Maintain your Compost Bin

Regularly turn your compost by using a pitchfork or shovel to mix the materials. Add additional compost materials as needed, and keep the compost damp but not too wet.
