Food Waste to Biogas

If food waste were a country, it would be the 3rd biggest emitter or CO2. It is also a huge contributor to methane emissions that are 20 times more environmentally damaging than carbon.

Food waste that can't be avoided can be turned into biogas on site and in seconds, reducing negative environmental impacts and generating significant cost savings

The Biodigester

The BIOMETA accepts all types of food waste (including cooked or raw meat, cooked or raw fish, shellfish, small bones) hot or cold.

How does it work?

Using a 23-litre Bio Bucket, fill the BIOMETA by opening a hatch which enables access to a receiving tray and close the hatch when finished.

Once the hatch is closed, the container is pressurized to prevent air from entering the machine. The process must be carried out without any air supply.

When the waste is in the bin with the hatch closed, an evolving, self-learning artificial intelligence system analyzes and recognizes the different waste inside. If the system detects "unnacceptable" waste (cutlery, dishes, etc.) it will display an alert on the control screen and will stop automatically to enable the user to remove unwanted waste, therefore preventing unforeseen contamination.

Once the waste has been accepted, the machine will programme itself according to the type and weight of waste present (+ - liquids). This enables it to work at maximum efficiency

Once these operations are complete, the bin opens from below and the waste enters the shredder where they are ground into pieces smaller than 12 mm.

The hygenization chamber with infrared lamp treats waste to ensure it meets European health standards.

Once the hygenization has taken place, water is added at an average, 1litre per kg of waste.

Finally, this mixture passes into the anaerobic digestion chamber where the temperature will rise to 40 ° C. In this chamber, there is a cocktail of bacteria which were previously deposited into the BIOMETA prior to its first use. (Unless the machine is stopped for a long time, the bacteria must not be changed).

For first time use, gas is produced after 24 hours of food waste being deposited into the main digester. Once in full time use, gas is produced immediately.

50kg / day of food waste = 15 to 25 m³ of gas / day

100kg / day of food waste = 40 to 50 m³ of gas / day

150kg / day of food waste = 60 to 75 m³ of gas / day

200kg / day of food waste = 80 to 120 m³ of gas / day

How do I use a Toto?

By referring to the manual, choose your programme depending on the room size. Select your programme and leave the room until the cycle has finished.
Can I be in the room when a Toto is on?

No, it is important that there are no people in the room when the Toto is in operation. All windows and doors should be shut until the cycle has finished, and we would suggest displaying a sign that tells people not to enter.
Where can I use a Toto?

In an indoor area that is in need of sanitisation, deodorisation of even as part of a deep clean. The Toto can also work to clean objects before or after regular cleaning.
Can I check how much ozone is in the room during the cycle?

Yes, by using the app. Simply connect to the Toto to see the cycle length and ozone levels. These numbers will disappear during the destruct part of the cycle and clear by the time the cycle ends.
