Creating a recycling society

Composting not only reduces the amount of waste in the rubbish bin, but it also lowers the cost of rubbish collection. Essential nutrients are returned to the soil, and expensive artificial fertilisers become redundant. Most important, composting does the rest of the world a great service by reducing the waste mountain.

The waste mountain is a vast and expensive problem, yet more than half our domestic rubbish is biodegradable and can be composted to produce, free-of-charge, natural nutrients for our gardens.

What is the Green Johanna?

Green Johanna is a unique closed, hot composting container, manufactured in Sweden. It has good ventilation, is easy to empty and the WINTER model comes with an insulating jacket which allows successful composting all year round.

For successful composting you need heat – but not so much that the micro-organisms are killed. The Green Johanna is self-regulating when positioned in the shade, generating the ideal temperature for the growth of micro-organisms and larger insects. In winter, the use of a removable (optional) jacket helps to maintain appropriate temperatures inside the unit.

All food waste for composting includes vegetables, fruit, dairy products, bread, bones, fish remains, soup, meat/bones, fish remains, egg shells, egg cartons, coffee filters, coffee grounds, tea bags, household paper. From the garden: wilted flowers grass clippings leaves twigs weeds bark etc.

Depending on the conditions the compost will be ready to use after four to six months. It will look and feel like soil, smell good, is pleasant to touch and crumbles readily. You can remove the compost from the Green Johanna via the two doors at the base. This ensures you harvest the mature compost (humus), allowing the upper layers to sink down and continue the transformation process. It’s even better if you have two Green Johannas, because you can alternate harvesting, allowing the compost to mature fully. Try to organise the process so you have the humus ready for spring, when your plants need the nutrients.
