The three-bin system is a good way to organize a larger composting operation by having separate bins for each stage of composting. Organic material is added to one bin and then transferred to each subsequent bin as the material breaks down. A three-bin system may be used actively as a hot composting system or passively as a cold composting system.
Material: A triple-bin composting system may be constructed from a large variety of materials. Since the structure is intended to last for several years, we recommend using treated wood, metal or concrete blocks.
Size: The minimum size recommended for each bin is 3 feet wide x 3 feet deep x 3 feet high. Larger bins may be constructed to accommodate the amount of organic material available for composting.
Additional bins may also be added as needed.
Hot composting is the preferred composting method since it will kill pathogens and weed seeds. To achieve this, the pile must be turned periodically to reintroduce oxygen and moisture to the pile.
