Create an environmentally friendly, economical composting system with Greenes Composting Bins. These cedar bins allow you to turn household waste into natural food 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, and allow materials to begin to compost. The bins’ open design makes it easy to turn the pile every two to three weeks with a shovel or pitchfork to aerate the product and speed up the breakdown process. Depending on the climate and the mix of materials, your compost will be ready to use in 3 to 12 months. To keep a continuous supply, create a multi-bin system with our add-on kits sold separately; after one bin is full and the materials have begun to break down, simply move them to the next bin and begin the process again in the first bin.
