The Green Johanna is a top-performing hot bin composter that turns food waste - including cooked food, meat, fish and dairy - and garden waste into quality compost within months.

Designed in Sweden and made in the UK from 100% recycled plastic, it has an expected lifespan of 10 years or more. 

The Johanna’s patented airflow and ventilation systems create optimum conditions for a busy eco-system of composting micro-organisms to digest waste, releasing energy as they do – hence the term hot composter.

One Johanna hot composting bin is designed to cope with the average food waste of a household of five and compostable waste from an average garden.
A free aerator stick comes provided.

Design features

The Johanna hot bin composter is made up of easily-assembled sections that form an enclosed unit with an integrated base plate that allows easy access to composting micro-organisms while deterring rodents. It should be placed in a shady area on soil, grass or gravel.

The secure, twistable lid regulates the ventilation system to adjust air circulation. In cold weather, twisting the lid to the maximum locked position helps to maintain the ideal temperature inside.  The efficient airflow system helps to maintain an aerobic environment, which, together with effective layering and aerating, prevents odours.

Two secure, good-sized sliding hatches at opposite sides of the unit mean that your finished compost is easy to access but won’t leak out before you need it.

 The Johanna has been designed robust enough to withstand Swedish winters and enable year-round composting. A Winter Jacket is available separately to provide insulation in cold weather.

Depending on conditions, your fresh organic compost should be ready to use after 4-6 months. 

Also Recommended: our bundle with a 12.5kg bag of Complete Rot for Grass -  a composting solution designed to facilitate the easy decomposition of grass clippings. Crafted from restructured organic waste material, this product harnesses the power of natural enzymes and abundant free carbon. Its purpose is to counterbalance the excessive nitrogen levels that typically hinder the composting process of grass clippings.
