Aerobin Compost Bin | Aerobin 200 & Aerobin 400

Developed in Australia, Aerobin specializes in innovative composting systems that simplify home composting through patented aeration technology and insulated construction. Designed for efficient, year-round compost production with minimal maintenance, Aerobin products help gardeners transform everyday kitchen and garden waste into nutrient-rich compost with ease.

Does the Aerobin 400 require turning?

No. The Aerobin 400 is designed to compost without turning or mixing. Its patented internal lung system continuously circulates air through the composting chamber, providing the oxygen needed for aerobic decomposition and eliminating the labor required by traditional compost piles.

What can I compost in the Aerobin 400?

The Aerobin 400 is ideal for fruit and vegetable scraps, coffee grounds, tea bags, eggshells, grass clippings, leaves, shredded paper, and most organic garden waste. For best results, maintain a balance of nitrogen-rich "green" materials and carbon-rich "brown" materials. Avoid meat, dairy, oils, pet waste, and diseased plants.

Can the Aerobin 400 be used year-round?

Yes. Its double-wall construction with a polystyrene-insulated core helps retain the heat generated during composting, allowing the system to remain active through cooler weather and extending the composting season in most climates.

What is the liquid collected in the bottom reservoir?

The Aerobin 400 collects nutrient-rich leachate in its built-in 4-gallon reservoir. When diluted with water, it can be used as compost tea to nourish flowers, vegetables, containers, and garden beds.

Does the Aerobin 400 attract rodents or pests?

The fully enclosed design helps discourage rodents and other common garden pests while minimizing odors associated with traditional compost piles. Avoiding meat, dairy, and oily foods will further reduce the chance of attracting unwanted visitors.

How long does it take to make compost?

Composting time varies depending on temperature, moisture, and the materials added. Under ideal conditions, finished compost can be ready in as little as 8 to 12 weeks, with a continuous supply available as new material is added to the top.

What's the difference between the Aerobin 200 and Aerobin 400?

The Aerobin 200 holds 55 gallons and is ideal for smaller households or compact gardens. The Aerobin 400 holds 111 gallons and is better suited for larger households, avid gardeners, and those who generate more kitchen and garden waste.

Does the Aerobin help control odors?

Yes. When maintained with the proper balance of green and brown materials, the enclosed design and continuous airflow help minimize odors while keeping compost neatly contained.

Can I compost year-round?

Yes. The insulated construction helps retain heat generated during composting, supporting microbial activity even during cooler weather.

Does the Aerobin attract rodents?

The enclosed design and secure lid help deter rodents and other pests far better than open compost piles.

Can I compost kitchen scraps?

What is compost tea?
