How does it work?

The recycling process is completely automatic – food waste is shredded, dried and sterilized without human intervention. Everyday usage simply involves the filling of the feeder with the waste to be processed. The only requirement of the operator is that they properly segregate the waste before filling the feeder. A list of products suitable for processing is contained within the instructions for use.

Garbage can be disposed of at any time, as needed throughout the day, and is subject only to the maximum processing capability of the bioreactor – a daily limit of 120 kg of waste.

Once a day, at 6 o’clock in the morning, the machine automatically ejects the recycled matter into a special container designed specifically for this use. The recycled matter is a high quality compost which research has shown is extremely beneficial for the healthy growth of a wide range of plants. Each 100kg of food waste produces approximately 15kg of compost which, when mixed with soil in a ratio of 1kg of compost to 4kg of soil, will provide a valuable source of fertilizer for your garden or greenhouse.

For your safety we recommended that the bioreactor be cleaned and maintained only by suitably trained personnel.








The only installation requirement for the KWM 100 bioreactor is that it should be placed in a ventilated room with a floor area of at least 7 m². There is no need for any plumbing to remove fluid waste because as much as 85% of the water contained in the waste is evaporated into the atmosphere.


Technical data



More information about the bioreactor can be found in the instructions for use where you can download an instruction manual.



The EU legislation (EC regulation 1774/2002 and consequent regulations in member states) concerning catering and gastronomic waste, as well as different regulations regarding specific hygienic aspects of the handling, storage and transport of the kitchen waste, lead to that this waste can not be treated together with the general waste stream and substantial costs are consequently generated.

A study shows that the cost of kitchen waste removal and processing in most EU member countries runs between 0,23 € and 0,75 € per kilogram.

The KWM-100 can process up to 100 kg of wet waste per day giving gross savings of at least 23 € per day. The operating costs of the KWM-100 are 4 to 5 € per day (electricity). Taking into consideration yearly service and spare parts costs of approximately 550 € the resulting net savings, not including capital costs, are approximately 17 € per day or 6,200 € per year for the minimum waste removal cost scenario. If the waste removal cost is 0,75 € per kg the savings are 25,185 € per year.

Elimination of conventional wet waste removal cost : 100 kg/day x 0.23 €/kg = 23 € /day (savings)

Electricity KWM-100 cost: 60 kWh/day x 0.075 €/kWh = 4.5 €/day,
other costs (service, replacement parts etc: ~1,5 € /day
– total cost excluding capital costs are ~6 € /day

Net savings per day: 23 € /day – 6 € /day = 17 € /day

For the year: 365 days x 17 € /day = 6,205 € /year

When one considers the economy of a KWM-100 installation also the simplification of the HACCP, handling, labour and storage costs should be considered because the alternative of conventional waste removal by specialized waste companies requires separate refrigerated storage, expands the HACCP procedure, thorough documentation, contracting and accounting. It is quite difficult to estimate these costs but one can safely assume them to at least 0.10 € per kg. With these additional savings of 3,600 € per year the total net savings after an installation of a KWM-100 exceed 9,800 € yearly!.
