Best Solar: Green Cone Solar Waste Digester Green Cone View On Greenconeusa.com Capacity: 1.59 gallons | Dimensions: 23 x 44 inches | Material: Recycled plastic The Green Cone Is a Backyard Solar Digester That Reduces 90% of Food Waste The Green Cone is an innovative composter that’s been popular since the 1980s. It’s not necessarily designed to give you garden soil in the end, but it is an eco-friendly way to process food waste and reduce trash. Senior Editor Katherine Martinko has used one for several years, and loves that critters can't get to the scraps. The way it works is you find a partly sunny spot in your yard to give the Green Cone a home. You fill it from the top with regular compost material, and it breaks down directly into the ground underneath. It has added help from the sun, thanks to the solar component. The nutrients this composter generates naturally benefit nearby soil, so consider positioning it near your garden. The Green Cone can take up to 2 pounds of food waste a day. Final Verdict Treehugger’s Best Overall pick is the EJWXO Compost Bin. We also like the affordable D.F. Omer 18.5 Gallon Tumbler Composter if you want a lower-cost and smaller option. What to Consider When Shopping for an Outdoor Compost Bin or Tumbler Bin v. Tumbler A tumbler makes the work of turning your compost a lot easier, but they can be a bit more expensive and some can be heavy to operate. Consider if the tumbler’s mechanism is comfortable for you to use, and if you have the physical space to turn it. Tumblers are great for patios and non-soil outdoor spaces, says Rebecca Louis, Master Composter and author of “City Compost.” However, a con is that these systems can be a bit more wet, even when they have aeration holes. With a bin, you have the option to slowly let your compost break down on its own, or you can speed things up by turning the material yourself using a pitchfork, rack, or shovel. They’re less likely to have moisture problems, but if your bin isn’t sealed, pests can be an issue. Some bins are open at the bottom, and work best when in contact with soil. Either way, you’ll want to balance the ratio of browns and greens in your composter. Size You’ll not only want to consider how much space you have when selecting your composter, but also how much material you wish to compost. If you’re mostly adding kitchen scraps, a smaller unit might do the trick, but if you have a lot of yard and garden waste, you’ll want one with a bigger capacity. If you don't have a lot of outdoor space, you may want to consider an indoor compost machine, which are small appliances that use energy to process food scraps into a dry, mulch-like material that can be used around the garden. Additional Features “I think a really great innovation that has emerged is having multiple chambers within a tumbler,” says Louis. That way, you can feed fresh scraps into one chamber while the other chamber holds older material that's still breaking down, finishing, and curing. When shopping for a compost bin, a helpful feature to look for is a panel at the bottom that opens and closes to allow you to harvest finished compost from the unit. Once you get the hang of composting, you’ll have a steady supply of nutrient-rich soil. Why Trust Treehugger?
