Not only that, they\u2019re free! Many companies still consider wood pallets a waste material and pay to have them hauled away with their garbage. If you see pallets at a business, ask if you can have them. Select four pallets of the same size to make the four sides of your bin. Connect the sides by tying them with string, rope, or wire, or by nailing them with double-headed nails. However you connect them, be sure to do it in a way that makes them easy to take apart when you want to move the pile or harvest the compost. Wood pallet bins are harder to turn regularly, so many people use them to compost slowly.<\/p>\n\n<\/div>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\" \/>\n\n\n<div class=\"wsu-note\">\n\t\n\t\t\t<div class=\"wsu-note__title\">\n\t\t\tMulti-bin Composting\t\t<\/div>\n\t\t\n\t\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" loading=\"lazy\" width=\"792\" height=\"493\" src=\"https:\/\/wpcdn.web.wsu.edu\/extension\/uploads\/sites\/48\/2026\/02\/3-compost-bins-composting-weeds-mulch-and-pinestraw--792x493.png\" alt=\"Multi Bin Composting setup.

They work well for small yards or patios and help keep pests like rodents and raccoons out. While some tumblers promise compost in just a few weeks, the material typically takes longer to break down, especially since the smaller volume does not retain enough heat to safely compost weeds gone to seed or diseased plants. Because tumblers are off the ground, they often lack worms, but adding a handful from another compost bin can help speed the process. For consistent use, having two tumblers allows you to alternate between decomposition phases, producing finished compost more steadily.<br><\/p>\n\n<\/div>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\" \/>\n\n\n<div class=\"wsu-note\">\n\t\n\t\t\t<div class=\"wsu-note__title\">\n\t\t\tPlastic Bin Composters\t\t<\/div>\n\t\t\n\t\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" loading=\"lazy\" width=\"2000\" height=\"1428\" src=\"https:\/\/wpcdn.web.wsu.edu\/extension\/uploads\/sites\/48\/2026\/01\/5-792x565.png\" alt=\"Upright plastic cylinder with side doors that are open exposing different layers to decomposing compost\" class=\"wp-image-24972\" srcset=\"https:\/\/wpcdn.web.wsu.edu\/extension\/uploads\/sites\/48\/2026\/01\/5-792x565.png 792w, https:\/\/wpcdn.web.wsu.edu\/extension\/uploads\/sites\/48\/2026\/01\/5-396x283.png 396w, https:\/\/wpcdn.web.wsu.edu\/extension\/uploads\/sites\/48\/2026\/01\/5-768x548.png 768w, https:\/\/wpcdn.web.wsu.edu\/extension\/uploads\/sites\/48\/2026\/01\/5-1536x1097.png 1536w, https:\/\/wpcdn.web.wsu.edu\/extension\/uploads\/sites\/48\/2026\/01\/5.png 2000w\" sizes=\"(max-width: 2000px) 100vw, 2000px\" \/><\/figure>\n\n\n\n<p>A contained systems designed for backyard composting in small to moderate spaces.
