Operating and maintaining

Since 2014, we have helped optimize the performance of biomethane plants. To do this, we offer services that leverage all operational drivers requiring concurrent management.



As organic waste experts, we bring together waste producers and short-circuit plants to recycle waste and benefit the country as a whole.

A project led by TER’GREEN, agricultural business SCAR, farming cooperative UDCA and SEM 24, this biomethane plant was built by NASKEO. It processes 30,000 tonnes of plant matter to generate 24.7 GWh HHV (260 Nm³/h) of biomethane that is injected into the GRTgaz network. The plant also produces 25,000 tonnes of digestate a year that is used by farming businesses in the region as a substitute for mineral fertilisers.
