Tawi Roller Stove
Cooking for you and your garden
A vibrant, productive garden can make the world seem a brighter place. As our climate changes gardens will need soil that is not just healthy but able to protect plants during extreme weather. Everything is going to have to become more climate resilient.
The Tawi Roller Stove is designed to make super adsorbent biochar. This is not the same as the standard biochar you buy online or in a garden centre. It has an enhanced ability to absorb liquids and adsorb nutrients.
Using layers of Tawi Roller Stove biochar between your vegetable waste will produce a long lasting, carbon-rich super compost full of nutrients. This compost will make your garden more climate resilient, draining your soil during wet weather and retaining water during droughts.
How we make our biochar based compost

1. Collect dry sticks
Instead of throwing your pruning sticks away you can now use them as fuel.
2. Cook a meal
With three distinct cooking surfaces the Tawi Roller Stove is surprisingly versatile.

Most gardens produce some woody waste, from fallen twigs to hedge trimmings. Once seasoned and dried this all makes excellent fuel for your Tawi Roller Stove. Think of this waste as a resource; part of your garden’s annual harvest. You can use chopped wood but, again, it must be dry and small in size.

The Tawi Roller Stove has three distinct cooking surfaces; a top wood-gas burner, a hotplate and a grill. These make it a very versatile stove.
You can cater easily for a group; for example: fry burgers or sausages on the top burner, and onions on the hotplate while toasting buns under the grill. Make a batch of chutney or jam; the top burner will bring a large preserving pan to the boil.

When you have finished cooking, the biochar will have collected in the water tank. Scoop the biochar out, remove any unburnt wood, and spread the biochar on a flat surface to drain. Do not let it dry out.
Before adding food waste to your composter spread a layer of biochar over the base (about 5cm deep). This will soak up the liquids that your compost produces as it decomposes.
Place your vegetable food waste on top of the biochar layer and spread it out. If you have any soil or compost which has worms in it, add a layer of that to help the decomposing process. Continue adding vegetable matter until the layer is around 8cm deep, then spread another layer of biochar over the top until you cannot see the vegetable waste. The layer of biochar will soak up excess liquids and allow air to move through the compost. This aeration is a really important part of our method. You can then add more vegetable waste. Repeat the layering process until your composter is full. We have called this technique ‘carbon composting’, as the only other material you have added to your vegetable waste is carbon in the form of biochar.
Not adding woody material to your compost will mean it is ready to use sooner than traditional mixed material compost. It does depend on the time of year, but your compost could be ready for use in around four months. Open the bottom of your composter and if you see dark brown compost then you can start to extract and use it. Don’t worry if there are still recognizable bits in there because these will continue to decompose in the soil. This is a very carbon rich compost, so you can apply it sparingly to the soil.
