What is pyro-gasification?

This thermochemical conversion process is used to transform organic matter into synthetic
gas, also known as synthetic gas. Two stages are needed to do this: 

• pyrolysis, which breaks the material down in 3 phases : solid, liquid and gaseous; 

• gasification, which transforms the solid and liquid phases into syngas.

During the pyro-gasification process, more than 90% of waste can be converted into syngas.
It is then combined with hydrogen by methanation to produce synthetic methane. This
sustainable gas has the same properties as natural gas and can be injected into transport
grids for habitual purposes.

Growth of the sector should be boosted by support mechanisms and the emergence of
demonstrators. In its Transition(s) 2050 report, the Ademe (French environmental and
energy management agency) therefore estimates that the potential synthetic methane
production by pyro-gasification would be 75 TWh _PCS.
