The JK 125, JK 270 and JK400 Composters Your own Ecological Revolution! |
|
All the Jora products are true composting machines. Whatever you put in them, the result is a finished compost ready to use on the garden. |
|
The JK 270 has been tested and evaluated in a project comprising 466 households in small houses and blocks of flats and day nurseries. The results proved most satisfactory as shown in the Report No. 4229 by the Swedish Authority for Environment Conservation. The JK 270 was also recently independently tested in the UK - see the report on page 6 of Devon’s Community Recycling & Community Composting Networks newsletter here: See also a review from the Editor of Environment UK magazine: |
Perhaps you want to 'do your bit' for the environment but never thought it was possible to compost all your kitchen waste... Perhaps the Council now only collects your food waste every other week and it rots and smells in a wheelie bin or black plastic sack... Perhaps you've tried composting before, and been unimpressed by the results - wondering if the stuff in the plastic bin at the end of your garden will ever stop smelling and rot down... Perhaps you've noticed how conventional composters can attract rats and mice, particularly if you are putting your kitchen waste in them... Perhaps you've considered buying a wormery-type composter, but have been put off by the thought of managing and cleaning up after all those wriggling, squirming worms... |
| ...if so, then the answer to all your composting concerns has arrived! | |
With a JK125 or JK270 composter, you don't have to be a gardener - or even have a garden! - to be able to produce your own nutritious compost. The JK125/270 helps you make perfect compost from your kitchen waste hygienically, with the minimum of fuss and mess (and no worms!). Your food waste will no longer rot and smell in your dustbin until collection day, and you can take comfort in the fact that you are playing your part in reducing the demands on our overburdened landfill sites. |

What is so different about the JK125/ 270?
The key features of the JK125/270 composter are:
|
| and whatever you put in them, the result is a proper, finished compost you can use straight on the garden! | |
| Rotation | |
Regular mixing is necessary for successful composting for two reasons:
The JK125/270 composter is constructed for ease and simplicity of rotation - it's simply turned by hand whenever waste is put in. |
|
| Insulation | |
The composting process generates heat, and the different microorganisms start working at different temperatures. The insulation in the JK125/270 composter allows the temperature to rise as high as 75 degrees C, resulting in the quickest and most efficient composting of your organic kitchen waste. (The photos opposite and below are of our own JK270 in operation at home.) |
 |
As temperatures drop in winter, the composting process will slow. However, because of its integral insulation, the JK125/270 will continue working long after other composters have stopped completely. The photos our JK270 were taken in January and February this year, when local temperatures got down below minus 5 degrees C on several occasions, and twice reached overnight lows of minus 7 degrees. |
|
| Dual Compartments | |
 |
The JK125/270 is divided into two compartments. One is being filled while the compost in the other matures. Once the compartment being filled can take no more, the mature compost is emptied from the other compartment, and the cycle begins again. You can see from the photo that it's time to empty the mature compost from the left-hand compartment and start filling it again, leaving the right-hand compartment to continue composting to maturity. |
| Rodent Proof | |
| The JK 125/270 is sited off the ground, either wall-mounted or freestanding, so there is no possibility of rodents or other pests gaining access to the waste in the machine. | |
| What can be composted? | |
The JK 125/270 composter will accept all organic waste generated by a household:
In fact, anything biodegradable - even pet waste, e.g. your rabbit or hamster bedding. In addition to the waste, which has a high nitrogen content, a source of carbon must be added to provide an energy source for the microorganisms. This is done by adding sawdust or wood pellets (which are simply compressed sawdust) when adding the waste. Add woodpellets in the ratio of 1:10 (pellets to waste). Add sawdust in the ratio of 1:3 sawdust to waste. The sawdust/wood pellets also absorb moisture, keeping the mixture relatively dry. We have tried using wood shavings but this was not so successful as they do not absorb the moisture to the same degree as sawdust or pellets. Wood pellets can usually be obtained from a solid-fuel appliance vendor as they are used as a biofuel in special wood-burning stoves and boilers. One of our customers has recently told us that coir works very well, as do dry leaves. Dry, chopped straw can also be used. Note to cat owners: wood pellets are also available as cat litter, so this is an excellent environmentally-friendly way of disposing of your cat waste! It will take somewhere in the region of 6 to 8 weeks for each chamber from starting to fill to production of compost - so once both chambers are in operation you should be emptying one chamber every 3-4 weeks or so.

To give you a good idea of the relative sizes, here is a side-by-side comparison of the JK 125 and JK 270. Note that the JK 270 now comes in the slightly darker green colour of the JK 125. |
To work out the appropriate size for you, the best thing is to measure your waste output over a typical week and compare with the capacities given below. If you are unsure, go for the JK 270. There is no harm in having additional capacity. Note that the machines are delivered flat-packed (like all things Swedish!) but are not difficult to assemble. Assembly instructions for the new model with the low stand can be found here: Assembly instructions for the new model with the high stand can be found here: |

The JK 400 can do the job of up to 3 JK270s! Ideal for small businesses:

These are the results from our JK 270 during winter 2005/6. It took us about 4 weeks to fill one compartment, which was then 'maturing' for a further 4 weeks while the other was filled - a total of 8 weeks from starting to fill with kitchen waste into its transformation into the material you see above - and this was during some quite prolonged cold spells - it produced the barrow full you see plus about a bucket full. During the summer the process only took about 6 weeks. |
