Product Information

Full details

The Original Organics Aerobin Hot Composter is designed for gardeners seeking an efficient, no-turn solution for garden and household waste. Its key benefit is rapid decomposition and nutrient-rich compost production in various climates, year-round, with minimal effort due to its internal "lung" system and moisture recirculation. A caveat is that it requires at least half-full capacity for optimal performance and two people for assembly. This 400-litre composter simplifies hot composting, producing compost suitable for all plants in as little as 90 days, while also reducing landfill waste.

FAQs

How long does it take to get finished compost?

Thanks to its insulated design, the Original Organics Aerobin can produce nutrient-rich compost in as little as 90 days, typically ready for use in 8-12 weeks.

Do I really never need to turn the compost?

Yes, the internal "lung" system is designed to provide continuous aeration, eliminating the need for manual turning.

What is the capacity of the composter?

The composter has a generous capacity of 400 litres.

What materials should I avoid adding?

Avoid adding meat, fish, dairy products, oily foods, diseased plants, or pet waste (from carnivorous animals).

How do I use the liquid fertilizer produced?

The collected liquid is a potent fertilizer. Dilute it with water (typically 10:1 ratio) before applying it to your plants.

What are the dimensions of the composter?

The dimensions are: Height: 120cm, Width: 74cm, Depth: 74cm.

Is assembly difficult?

Assembly requires two people and clear instructions are provided. While not complex, having a second person makes the process much easier.

Troubleshooting

Composter not heating up or decomposing slowly

Ensure the composter is at least half-full. Check the moisture level – it should be damp like a wrung-out sponge. Add more 'green' (nitrogen-rich) material if it seems too dry or 'brown' (carbon-rich) material if it's too wet. Ensure waste is properly mixed and shredded if woody.

Unpleasant odors emitting from the composter

This usually indicates an imbalance, often too much 'green' material or excess moisture leading to anaerobic conditions. Add more 'brown' material (e.g., dry leaves, shredded cardboard) and ensure good aeration by gently stirring the top layer if possible.

Leachate not collecting

Verify that the leachate hose is properly attached and not kinked or blocked. Ensure there is sufficient moisture in the compost pile to generate liquid. The composter may need more time to start producing leachate if it's newly set up or very dry.

Pests attracted to the composter

Ensure the lid is securely closed and that no prohibited items (meat, dairy) are being added. The vermin-resistant design should prevent most issues, but maintaining proper composting conditions discourages pests.

Pros and Cons

Pros

  • Requires no manual turning, saving time and effort.
  • Produces compost quickly, even in cooler climates.
  • Generates valuable liquid fertilizer as a byproduct.
  • Reduces household and garden waste significantly.
  • Vermin-resistant design for cleaner composting.
  • Provides nutrient-dense compost for healthier gardens.

Cons

  • Requires assembly by two people.
  • Needs to be at least half-full for efficient operation.
  • Optimal results depend on proper waste mixing and shredding of woody materials.
  • Initial setup and material addition might require some learning curve.
  • Larger woody materials may take longer to break down without pre-shredding.

Setup, Compatibility & Care

Setup: The Aerobin requires assembly, which is best done with two people. Ensure it is placed on a level surface in a convenient location, preferably with some sun exposure to aid heating.

Getting Started: For optimal performance, add a 5cm layer of non-sterilised compost to the base to introduce beneficial microorganisms. Begin adding a mix of garden and kitchen waste, aiming to keep the composter at least half-full. Pre-mixing waste and shredding woody materials will significantly speed up the composting process.

Compatibility: The Aerobin is designed to process a wide range of organic garden waste (grass clippings, leaves, plant trimmings) and kitchen scraps (vegetable peels, fruit cores, coffee grounds, tea bags). Avoid adding meat, dairy products, oily foods, or diseased plants.

Care: To maintain performance, ensure the composter remains moist but not waterlogged. The internal "lung" system aids aeration, but occasionally checking for blockages is advisable. Clean the exterior with a damp cloth as needed. The leachate hose should be checked periodically to ensure it is not blocked.
