Create an environmentally friendly and cost-effective composting system with Greenes Composting Bins. Made from North American cedar, these bins allow you to turn household waste into natural fertilizer for your lawn, garden, and flower beds. Simply layer "greens" (such as vegetable and fruit peelings, coffee grounds, tea bags, and grass clippings) and "browns" (such as eggshells, cardboard, corncobs, and cotton towels), then allow the materials to begin composting. The bins' open design makes it easy to turn the pile every two to three weeks using a shovel or pitchfork, aerating the compost and speeding up the breakdown process. Depending on your climate and the mix of materials, your compost will be ready to use in 3 to 12 months. For a continuous supply of compost, consider creating a multi-bin system with our add-on kits. After one bin is full and the materials begin to break down, simply transfer them to the next bin and start a new batch in the first. A three-bin system will keep the process moving seamlessly. The composting bin is 36 in. x 36 in. x 31 in./23.25 cu. ft. and includes 4 posts, 24 boards, and 40 spacers. Cover with a tarp or plywood (not included) if desired.
