Extra large expandable outdoor compost bin

$51

Catalog updated 2026-11-04

This is the largest stationary bin in this catalog, offering a 500 gallon capacity for serious gardeners and large properties. The expandable wrap-around design can be adjusted to fit the specific volume of waste you need to process. It is particularly effective for managing seasonal surges of fallen leaves and grass clippings.

The structure is designed to be placed directly on the soil, allowing for natural drainage and the entry of beneficial insects. The large volume helps the pile retain heat, which accelerates the breakdown of tough organic matter. It is a simple, low-maintenance solution for those who prefer the 'add and wait' method of composting.

The material is weather-resistant and designed to hold its shape even when full. Because it uses a buckle system, you can easily open the side of the bin to turn the pile or extract finished compost from the bottom. This unit provides an economical way to handle massive amounts of organic waste without multiple smaller bins.
