GAIA GC 100 Food Waste dehydrator

Gaia is a process of dehydrating and sterilizing organic waste at source.


Gaia is a system for dehydrating organic waste -in particular food waste – at source, preventing the waste going to landfill where it would rot, producing methane (25 times more potent than C02 as a greenhouse gas) and leachate which poisons water tables. Using Gaia allows greenhouse gas emissions to be reduced by up to 90%.

The Gaia process  requires that, as much as possible, the organic waste should be segregated from other types of waste. Inorganic contamination will be unaffected by the process but may limit the options for the use of the organic biomass that results from the dehydration cycle.

It is increasingly common for companies to segregate their waste into organic and inorganic streams, seeking solutions for the former that grant a more environmentally suitable outcome than landfill dumping




The waste is placed inside a drum through which hot air is circulated while a rotating paddle helps breakdown the physical structure of the waste. Over a period of up to nine hours the moisture content is driven off and condensed for (optional) recovery for use as grey water. The solid mass in the machine is reduced in weight and volume by 85 -90% and is rendered fully sterile by the process

No, absolutely not. Composting is a microbial process that takes many weeks to complete. GaiaRecyle takes only a few hours yet still produces a biomass that can be used as a soil amendment

Gaia is a batch process so, once the unit is started, it runs continuously through its preset cycle. We recommend that the process should not be stopped to add more waste as this may give an inconsistent result. After one process is finished, another can be started immediately

Absolutely not. Unlike other methods, Gaia requires NO sawdust, NO microbes or enzymes, NO water. You simply load, press “Start” and walk away

No it doesn’t as the machine automatically senses when the added product has dried enough. We recommend using it full however to reduce your energy consumption. An added benefit is that you can store waste in the machine until ready to run and it won’t smell or attract vermin.

The process is not affected in any way if paper, plastic packaging or inorganics such as knives, forks and even glass are present. It is desirable to reduce the amount of contamination as much as possible depending on what is the intended use of the biomass. On smaller models like the Gaia GC 100 alarms will go off when metal utensils are detected. On the larger models the alarms are not an issue

Yes, but this process is particularly suited to food waste, which is a category that is not easily treated by other methods.

Capacities range from 30 kg per day up to 3000 kg. per day in modular units and then up to 100 tons per day in purpose built plant!

There are several. It can go to landfill but there are better environmental possibilities, including:

  • use as a soil amendment. It is classified as a “High Nitrogen, slow release soil conditioner”
  • it can be compressed into pellets or briquettes and used a fuel for boilers and stoves. Because the biomass is high in nitrogen and low in carbon, its emissions are much less than those of coal and coke. Further, the carbon in the biomass is considered as being already in the Carbon Cycle whereas the emissions from coal that has been sequestered for centuries are net additions to the carbon load in the cycle.
