The Exaco Trading Aerobin 200 is a 55-gallon insulated compost bin designed for year-round composting with minimal effort. Developed in Australia, it features a patented internal aeration "lung" system that draws fresh air into the pile and releases warm gases naturally, promoting aerobic composting without any need for turning or mixing. Double-walled, foam-insulated sides, lid, and access doors retain the natural heat of decomposition, accelerating breakdown even in cooler weather. The bin stands 46 inches tall with a 20 by 20 inch footprint, weighs 30 pounds, and is constructed from BPA-free virgin polypropylene and high-density polyethylene.

Two access doors at the base make harvesting finished compost straightforward, while a built-in reservoir collects nutrient-rich leachate that can be drained via an included hose and cutoff valve and used as a diluted liquid "compost tea" fertilizer for plants. The tightly fitted closed construction keeps pests and rodents out while containing odors inside. The bin requires no sun exposure to function, and the lid features hooks for hanging it on the side while loading materials.
