The HotBin Mini 100 Litre Compost Bin hot composts all year round to recycle your food and garden waste even quicker. It works well in the sun or shade but should always be sited on an even surface.

Traditional composting takes 18 months in a cold heap at 10°C, but hot composting takes just 90 days in a HotBin running at 60°C. Explore our entire HotBin range here.

Bacteria decomposing the waste generates heat within the HotBin Mini 100 Litre Compost Bin, which provides effective aeration through the bottom air inlet plate and the air outlet rotating valve. It also removes excess water through the valve as steam and allows you to control the rate of heat loss.

The HotBin can achieve hot composting between 40-60°C, which means it can produce a rich compost faster. As hotter temperatures can be achieved, you can recycle more types of household waste, such as food waste (including cooked left-over food waste, eggshells, mouldy bread, fish, meat with bones, and dog and cat litter) and grass/garden cuttings.

Made from Expanded Polypropylene or EPP, the HotBin is made of just 4% raw material and 96% air making it extremely resourceful and efficient!

Key Points

  • HOTBIN creates the perfect conditions in your heap to expediate composting, making the process quicker and easier.

  • Produce rich, peat free, homemade compost every 90 days with no need to turn the heap.

  • Awarded the RHS Chelsea Garden Product of the Year 2019.

  • To maintain high temperatures, feed the HOTBIN 2-3 times per week, evenly stirring the shredded paper to absorb moisture and woodchip to improve airflow.

Top Tip
Do not use tools to lever off the hatch, or force the hinge lid backwards, and ensure the valve is kept free of dirt and/or snow.

Quick Facts

  • HOTBIN is a compact, self-contained composter (with a base).

    Keep the surrounding area, hatch and lid free of any food waste to prevent any interest from pests.

  • HOTBINs are super durable, weather and frost proof.

    Take care when removing compost with pointed/sharp tools to prevent any accidental damage.

  • Considering a location is important for your HOTBIN.

    Place your HOTBIN on a HOTBIN plinth or a hard, flat surface in sunshine or shade. If you have had rats previously in your garden, be careful with the addition of food waste.

  • Keep your HOTBIN closed.

    Always keep the hatch and lid tightly closed. Safely secure cam straps around the hatch; any gaps in the door/lid results in the bin losing heat and odours escaping.
