Green Johanna Hot Composter

Product Information

As the micro-organisms break down the waste, they generate heat. As the temperature in the compost fluctuates, the types of micro-organisms present also change. The smaller the waste items are chopped or shredded, the greater the surface area for microbes to work on and the faster the pile will heat up. Items that are added whole, such as apples or carrots etc, will take longer to break down. Egg shells are best added crushed or ground. Garden waste should be chopped into pieces no larger than 5cms or shredded.

Food waste should be dropped into the Cone directly, not in bags of any kind, even compostable ones. Waste lands in the underground basket, where micro-organisms and worms enter and begin to break it down. The upper part of the Cone above ground remains empty: the inner and outer cones create a heat trap of circulating air that facilitates the growth of beneficial micro-organisms and promotes the aerobic digestion process. 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. For those of you who don’t know, the Green Johanna is a “unique closed, home composting container” but it can also take food waste including cooked food. Made in the UK from 100% recycled plastic, the Green Cone has an expected lifespan of 10 years or more.

Compost Tumblers

Embedding the Cone in soil means that bacterial digestion occurs below ground level so any odours are absorbed by the soil. We have tried various things in the past to deal with our food waste to save them from the bin without success. We tried a wormery, but managed to kill off the worms (although I would like to try this again) and we have also tried Bokashi bins, but we didn’t really have enough garden to dig the fermented waste into, so it all just sat in the garage for several months until we threw it away… You need to allow 2 - 5 days for delivery, and we can post to anywhere in mainland Britain. See below if you are in Highlands and Islands.

The Green Johanna is the garden compost bin with a difference. This hot composter recycles all kinds of waste food - even cooked food, meat (except bones) and fish - into natural organic compost. If you love recycling and would like a greener garden, the Green Johanna is for you. Simply install in a shady, sheltered spot and fuel with a few centimetres of garden waste. Then add two layers of food waste for every layer of garden waste. 80 x 26.5 x 80cm. 330 litres. The Green Cone is a solar-powered food waste digester that efficiently disposes of all food waste - including cooked food, meat, fish (even bones) and dairy - with no turning or stirring required.

With Your Food Waste

Then we needed a layer of grass mowings/clippings. Hubby was again not feeling the Green Johanna love, and refused to mow the lawn for us to generate some clippings (some tosh about frosts and killing the grass) BUT after yet another argument heated debate, we set off to the local park with a pair of garden shears and a big bag! (I love my hubby :)) Dobies strives to ensure that all its plants are delivered to you in the perfect condition for planting. While the majority of our nursery plants cope well with slight delays in intransit, sadly, the time it takes to deliver to certain locations in the UK means that we can't guarantee this for some of our smaller plug products and tender bedding and vegetable lines, which do not respond well to the extra journey time. So regretfully while we offer the majority of our live plant offering nationwide, we are unable to ship plugs, begging plants and tender vegetable plants to the following areas: HS, IV41-IV49, IV51, IV55-56, KW15-KW17, PA34, PA41-48, PA60-PA78, PA80, PH40-PH44, TR21-TR24, ZE1-ZE3. Designed in Sweden and made in the UK from 100% recycled plastic, it has an expected lifespan of 10 years or more. The regular addition of a little accelerator powder (a mixture of natural bacteria on a cereal base) is necessary to boost the digestion process. There is plenty of capacity for ALL your food waste, as well as plenty of garden waste as this hot compost bin has 330L capacity.

The Green Johanna is designed to take 1/3 garden waste to 2/3 food waste, and works best in a shady spot. Hopefully this should work really well for us, as we have a shady, not very big garden, so don’t generate a huge amount of garden waste. The Green Johanna was developed in Sweden to provide a simple, easy to use compost system to safely compost all degradable kitchen waste all year round! The well thought out, patented design of Green Johanna means you do not have to know much about composting - with Green Johanna everyone can compost now! Green Johanna can compost two parts food waste to one part garden waste. All food waste including meat, fish and bones can be put in Green Johanna.It’s important that these ventilation holes are left clear or the ventilation system will not function.

Made in the UK from 100% recycled plastic, it has a five-year guarantee and expected lifespan of 10 years or more.Then add the upper rings so that they overlap the section below by about 5cms. Ensure that the ventilation holes at the top of the composter remain uncovered. The ventilation holes at the top and bottom of the Johanna must not be covered or the ventilation system will not function. In the first year it may take 6-8 months to get your first batch of compost. After that it should take 4-6 months. The Johanna 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. Since 2021 Johanna used her lived experience to contribute to Patient and Public Involvement as part of the Patient Advisory Group for Bowel Research UK, and more recently as a member of Bowel Cancer UK's 'Never Too Young' working group; she also worked as Patient Educator for the School of Medical Education at King's College London. Ann Gow, Professor of Information Studies, who was a friend and colleague of Johanna, said: “Johanna's presence within the academic community and her impact on the lives of her students and colleagues were nothing short of remarkable.
