Biotechnology that eats organic material from waste

Our XO systems combine robust, clever engineering with bio-stimulants, turning waste containing organic material into Refuse-Derived Fuel (RDF).

Inside the controlled environment of our XO machines, we use unique blends of bacteria to catalyse the aerobic reaction.

Through this clever application of biotechnology, we achieve in 48hrs what others take 16 weeks to do.

Our technology step-by-step


Waste stream testing

The XO technology is the only on-site solution which can handle a variety of waste streams including organic content.

We test our clients’ waste to ensure the most efficient bio process with a significant mass reduction.


Waste shredding

Waste goes through an industrial shredder.

This begins the process and ensures that a consistent and optimum particle size enters the biomass.


Heating and bacteria

The system initially heats the waste to kick start the bacterial activity.

Once optimum temperatures have been achieved the exothermic reaction self-generates the majority of the heat required. The heating system is then used to maintain the temperature above a minimum threshold for continual operation 24/7.

This creates resiliency in the system for periods of inactivity.



Advetec's unique bio-stimulants are added automatically.

This ensures a robust and strong biomass is maintained and allows for the system to cope with the inevitable existence of biocides within the waste stream.


Rapid digestion

Each Advetec XO machine has multiple chambers.

These chambers are aerated to allow the aerobic process to flourish. The waste is indexed through the process, allowing for the addition of fresh waste at regular intervals.


Outcome: 50% waste mass and 70% waste volume reduction

The output material is called post process FLOC.

It typically has a moisture content less than 15% (with organic matter reduced significantly during digestion) and has an increased calorific value.

Depending on the waste stream and customers’ requirements, the FLOC can be used as Refuse-Derived Fuel (RDF) or have further value extracted benefiting the circular economy.
